What to do if a cow is bitten by a tick?

Immediate Actions Upon Discovering a Tick Bite

Identifying the Tick and Bite Area

Visual Inspection

Visual inspection is the first critical step after a bovine is found with a tick attachment. The examiner should approach the animal calmly to reduce stress and ensure a clear view of the affected area.

During the examination, observe the following:

Presence of the tick’s mouthparts embedded in the skin; look for a small, dark puncture or a raised nodule.
Condition of surrounding tissue; note swelling, redness, or discharge that may indicate secondary infection.
Number of ticks on the animal; a heavy infestation suggests the need for broader control measures.
Lesions or ulcerations around the bite site; assess depth and size to determine treatment urgency.
Signs of systemic reaction, such as fever or loss of appetite, which may accompany severe infestations.

After confirming the tick’s location, gently separate the animal’s hair to expose the skin fully. Use a clean, bright light to enhance visibility of minute details. If the tick is still attached, refrain from pulling; instead, employ a fine‑tipped forceps to grasp the tick as close to the skin as possible and extract it with steady, upward pressure. Following removal, clean the area with an antiseptic solution and monitor for changes over the next 24–48 hours. Regular visual checks should become part of routine herd management to detect new infestations early and prevent disease transmission.

Palpation

Palpation provides immediate assessment of the attachment site and surrounding tissue after a tick has attached to a bovine. By applying gentle pressure with the fingertips, the practitioner can locate the tick, evaluate skin integrity, and detect any swelling or inflammation.

Key actions during palpation:

Locate the tick head or mouthparts by feeling for a small, firm nodule beneath the hair coat.
Assess the surrounding area for erythema, heat, or edema, indicating local reaction.
Determine the depth of attachment; a tick embedded deeply may require careful removal to avoid tearing the mouthparts.
Examine adjacent lymph nodes for enlargement, suggesting systemic involvement.

After the tick is removed, palpation continues to verify complete extraction. The practitioner should re‑examine the bite site for residual mouthparts, which appear as a tiny, hard projection. Persistent tenderness or fluctuance may signal secondary infection, warranting antimicrobial therapy.

Regular palpation of the bite region during the following 24‑48 hours ensures early detection of complications. Any increase in swelling, discharge, or pain merits veterinary intervention.

Tick Removal Techniques

Proper Tools for Removal

When a tick attaches to a bovine, removal should be performed with equipment that minimizes tissue damage and reduces the risk of pathogen transmission.

Recommended instruments include:

Fine‑point tick removal forceps or specialized tweezers designed to grasp the tick close to the skin.
Disposable nitrile gloves to protect the handler and prevent cross‑contamination.
Sterile cotton swabs or gauze pads soaked in an approved antiseptic for cleaning the bite site before and after extraction.
A small, sharp scalpel or blade for cutting the tick’s mouthparts only when the head remains embedded and cannot be withdrawn whole.
A sealable container with a disinfectant solution for safe disposal of the removed tick.

Procedure: grasp the tick with the forceps as near to the skin as possible, apply steady, gentle traction, and avoid twisting. If resistance occurs, use the scalpel to sever the embedded mouthparts, then cleanse the wound with the antiseptic swab. Dispose of the tick in the prepared container and replace gloves before handling additional animals.

Using only the specified tools ensures rapid, safe removal and limits exposure to tick‑borne diseases.

Step-by-Step Removal Process

When a bovine presents a tick attachment, immediate removal prevents disease transmission and tissue damage. The following procedure outlines a safe, effective method.

Prepare equipment – Obtain fine‑point tweezers or a specialized tick removal tool, disposable gloves, antiseptic solution, and a clean container for disposal.
Secure the animal – Restrain the cow calmly to limit movement; use a chute or stanchion as needed.
Locate the tick – Examine the hide, focusing on ears, udder, and underbelly where ticks commonly embed.
Grasp the tick – Position the tweezers as close to the skin as possible, gripping the tick’s head without compressing the body.
Apply steady traction – Pull upward with consistent force, avoiding twisting or jerking motions that could leave mouthparts embedded.
Inspect the removal site – Verify that the entire tick, including mouthparts, has been extracted; if fragments remain, repeat the grasp and pull step.
Disinfect the area – Apply antiseptic to the bite site to reduce infection risk.
Dispose of the tick – Place the removed specimen in the container, submerge in alcohol, or incinerate to prevent re‑infestation.
Monitor the animal – Observe the site for swelling or signs of infection over the next 24–48 hours; administer veterinary treatment if abnormalities develop.

Following these steps ensures thorough tick removal while minimizing stress to the animal and safeguarding herd health.

Post-Removal Care of the Bite Site

After a tick is extracted from a bovine, the bite site requires prompt attention to prevent infection and promote healing. Begin by applying a sterile saline solution or mild antiseptic directly to the wound. Pat the area dry with a clean gauze pad; avoid rubbing, which can damage surrounding tissue.

Inspect the skin for residual mouthparts or signs of inflammation. If any fragment remains, repeat the removal process using fine-tipped tweezers, grasping the tick as close to the skin as possible and pulling straight upward. Discard the tick in a sealed container for laboratory identification if needed.

Implement a short-term care regimen:

Apply a broad-spectrum topical antibiotic ointment twice daily for 3–5 days.
Cover the site with a breathable dressing if the area is in a high‑traffic region of the hide.
Record the exact location, size of the lesion, and date of removal for herd health tracking.
Monitor temperature, swelling, and discharge; increase observation frequency during the first 48 hours.

If redness expands, pus appears, or the animal exhibits fever, initiate veterinary consultation promptly. Systemic antibiotics may be required based on clinical assessment. Maintain clean housing conditions and ensure the herd’s tick control program remains active to reduce repeat incidents.

Potential Health Risks and Monitoring

Diseases Transmitted by Ticks

Anaplasmosis

Anaplasmosis is a bacterial disease of cattle caused by Anaplasma marginale, transmitted primarily by ticks that have fed on infected animals. The pathogen invades red blood cells, leading to hemolytic anemia and reduced productivity.

Typical manifestations after a tick attachment include fever, pale mucous membranes, rapid breathing, jaundice, and decreased milk yield. In severe cases, hemoglobinuria and weight loss may occur.

Diagnosis relies on laboratory analysis of blood samples. Preferred methods are:

Blood smear microscopy to detect intra‑erythrocytic organisms.
Polymerase chain reaction for definitive identification.
Serological tests such as competitive ELISA to assess exposure.

Therapeutic intervention should commence promptly. Recommended regimen comprises:

Intravenous administration of oxytetracycline at 10 mg/kg body weight, repeated after 48 hours.
Supportive care including fluid therapy and anti‑inflammatory agents.
Monitoring of packed cell volume daily until stabilization.

Prevention focuses on tick control and herd management. Effective strategies include:

Regular application of acaricides to grazing areas and animal hides.
Pasture rotation to disrupt tick life cycles.
Vaccination with commercial A. marginale vaccines where available.
Routine health monitoring to detect early infection.

Implementing these measures reduces the risk of disease transmission following tick bites and safeguards herd health.

Bovine Babesiosis

Bovine babesiosis is a hemoparasitic disease caused primarily by Babesia bovis and Babesia bigemina, transmitted through the bite of infected ixodid ticks. The parasite invades red blood cells, leading to hemolysis, anemia, fever, and possible mortality if untreated.

Clinical signs appear within days of attachment and include elevated body temperature, pale mucous membranes, jaundice, reduced milk yield, and lethargy. Laboratory confirmation relies on microscopic examination of stained blood smears, polymerase chain reaction, or enzyme‑linked immunosorbent assay.

Effective management comprises immediate supportive care and specific antiprotozoal therapy. Recommended actions are:

Administer an appropriate dose of imidocarb dipropionate intramuscularly or intravenously; repeat after 48 hours if parasitemia persists.
Provide fluid therapy to correct dehydration and maintain electrolyte balance.
Supply iron‑rich supplements or blood transfusions for severe anemia.
Monitor rectal temperature, hematocrit, and parasitemia daily for at least five days.

Prevention focuses on tick control and herd immunity. Implement regular acaricide treatments, pasture rotation, and strategic use of vaccines containing attenuated Babesia antigens. Maintaining a clean environment and promptly removing attached ticks reduce infection risk.

Lyme Disease (Ruminant Implications)

Lyme disease, caused by Borrelia burgdorferi, is transmitted to cattle through the bite of Ixodes ticks. Infection can lead to arthritis, lameness, fever, and reduced milk production, affecting herd profitability.

Clinical observation after a tick attachment should focus on joint swelling, gait abnormalities, and intermittent fever. Early detection reduces the risk of chronic joint damage.

Immediate actions include:

Grasp the tick as close to the skin as possible with fine‑tipped forceps.
Pull upward with steady pressure; avoid twisting to prevent mouthpart retention.
Disinfect the bite site with a suitable antiseptic.
Record the attachment time, tick species (if identifiable), and the animal’s identification.

Diagnostic evaluation involves:

Serological testing for anti‑Borrelia antibodies (ELISA, Western blot) to confirm exposure.
Polymerase chain reaction on blood or synovial fluid for pathogen detection.
Joint aspiration when arthritis is suspected to assess inflammatory cells.

Therapeutic protocol recommends:

Administration of doxycycline (5 mg/kg body weight per day) for 14 days, or oxytetracycline (10 mg/kg intramuscularly) for 5 days if doxycycline is contraindicated.
Anti‑inflammatory medication (flunixin meglumine 2.2 mg/kg IV) to alleviate joint pain.
Supportive care, including adequate hydration and nutrition, to promote recovery.

Preventive measures focus on herd management:

Conduct regular pasture inspections and remove tall vegetation that shelters ticks.
Apply acaricide treatments to cattle according to veterinary guidelines.
Rotate grazing areas to interrupt tick life cycles.
Implement routine tick checks, especially during peak activity months (April–September).

Symptoms to Monitor For

Behavioral Changes

After a tick attaches to a bovine, the animal may exhibit distinct behavioral alterations that signal discomfort or the onset of disease. Recognizing these changes promptly enables effective intervention.

Typical behavioral indicators include:

Reduced grazing time, often accompanied by a tendency to remain near the herd’s periphery.
Increased restlessness, manifested as frequent shifting, head tossing, or attempts to dislodge the parasite.
Elevated respiratory rate and occasional open‑mouth breathing, suggesting systemic stress.
Decreased milk production, reflecting metabolic disruption.
Reluctance to lie down, resulting in prolonged standing and potential hoof strain.

When such signs appear, immediate actions should follow:

Conduct a thorough physical inspection of the hide, focusing on common attachment sites such as the ears, neck, and udder.
Remove visible ticks using calibrated tweezers, ensuring the mouthparts are extracted completely to prevent secondary infection.
Apply a topical acaricide approved for livestock, adhering to the manufacturer’s dosage and withdrawal guidelines.
Collect a blood sample for laboratory analysis to detect tick‑borne pathogens, including anaplasmosis and babesiosis.
Initiate supportive care, such as supplemental electrolytes and anti‑inflammatory medication, under veterinary supervision.
Monitor the herd for similar behavioral shifts, isolating affected individuals to limit pathogen spread.

Persistent or worsening behavioral anomalies—especially loss of appetite, lethargy, or abnormal gait—require urgent veterinary evaluation. Early detection and response mitigate health risks and preserve productivity.

Physical Manifestations

When a tick attaches to a cow, visible changes appear on the animal’s integumentary system.

Physical manifestations include:

Localized swelling at the attachment site
Redness and heat surrounding the bite
Presence of an engorged tick or a detached exoskeleton
Skin ulceration or necrotic tissue development
Discharge or crust formation indicating secondary infection
Excessive licking or scratching of the affected area
Hair loss around the lesion

Additional observations may involve changes in gait if the bite occurs near a joint, and the emergence of small puncture marks surrounding the primary lesion. Prompt identification of these signs enables immediate veterinary intervention.

Changes in Appetite and Milk Production

A tick attachment on a bovine frequently triggers a decline in feed intake. The parasite’s saliva contains compounds that suppress appetite, leading the animal to consume less roughage and concentrate. Reduced consumption diminishes energy availability for lactation, causing a measurable drop in milk yield within days of the bite.

Monitoring feed behavior and milk output provides early indicators of tick‑related stress. When a decrease of more than 10 % in daily milk production coincides with reduced grazing, immediate intervention is warranted.

Recommended actions:

Conduct a thorough physical inspection of the hide, focusing on typical attachment sites such as the udder, neck, and tail base.
Remove attached ticks with forceps, grasping close to the skin to avoid leaving mouthparts.
Apply an approved acaricide to the entire animal, following label dosage and withdrawal periods to prevent residue in milk.
Administer a short‑term anti‑inflammatory or antihistamine regimen to alleviate local irritation and support appetite recovery.
Supplement the diet with high‑energy concentrates and electrolytes for at least 48 hours to counteract the nutritional deficit.
Record milk volume daily for a week; expect a gradual return to baseline as the tick burden is cleared and inflammation subsides.

Prompt removal of ticks and supportive nutritional management restore normal feed intake and stabilize milk production, minimizing economic loss.

Veterinary Consultation

When to Seek Professional Help

A tick attachment on a cow can introduce pathogens, cause anemia, or trigger severe local inflammation. Recognizing situations that require veterinary intervention prevents complications and safeguards herd health.

Presence of fever, lethargy, or loss of appetite indicates systemic infection and warrants immediate professional assessment.
Rapid swelling, ulceration, or necrosis at the bite site suggests aggressive tissue damage; prompt veterinary care is essential.
Detection of multiple engorged ticks or a sudden increase in tick numbers signals a heavy infestation that exceeds routine control measures.
Observation of abnormal blood parameters, such as reduced packed cell volume or elevated white‑blood‑cell count, necessitates diagnostic testing by a veterinarian.
Failure of standard tick‑removal techniques to eliminate the parasite, or recurrence of symptoms after initial treatment, requires expert guidance.

In cases where any of these signs appear, contacting a qualified veterinarian without delay ensures appropriate diagnostics, targeted medication, and effective herd‑level management. Ignoring these indicators increases the risk of disease transmission, production losses, and animal welfare concerns.

Diagnostic Procedures

When a tick attaches to a bovine, accurate diagnosis determines appropriate treatment and prevents disease spread.

Initial assessment includes a thorough visual inspection of the attachment site. Remove the tick with a fine‑pointed forceps, taking care not to crush the body. Preserve the specimen in a sealed container for laboratory identification, as species determination influences disease risk evaluation.

Laboratory diagnostics proceed as follows:

Microscopic examination of the tick’s salivary glands to detect pathogens such as Babesia, Anaplasma, or Ehrlichia.
Polymerase chain reaction (PCR) on blood samples to amplify DNA of specific tick‑borne organisms, providing rapid and sensitive confirmation.
Serological testing (ELISA or indirect immunofluorescence) to identify antibodies against common bovine tick‑borne diseases, indicating current or past exposure.
Complete blood count (CBC) and biochemistry panel to reveal anemia, leukocytosis, or organ dysfunction associated with infection.

Interpretation of results should consider regional tick species prevalence, the cow’s health status, and any recent clinical signs such as fever, lethargy, or reduced milk yield. Prompt confirmation of pathogen presence enables targeted antimicrobial or antiparasitic therapy, reducing morbidity and safeguarding herd health.

Treatment Options

When a bovine hosts a feeding tick, immediate attention reduces the risk of pathogen transmission and tissue damage.

Remove the tick promptly with fine‑pointed tweezers or a dedicated tick extractor. Grip the mouthparts close to the skin, pull straight upward without twisting.
Apply a topical acaricide after removal. Products containing pyrethroids or organophosphates provide residual protection; follow label dosage for the animal’s weight.
Administer a systemic acaricide if the infestation is extensive. Injectable ivermectin or doramectin delivers rapid internal action against attached and hidden stages.
Clean the puncture site with sterile saline. Disinfect with a suitable antiseptic, such as chlorhexidine, to prevent secondary bacterial infection.
Observe the wound for signs of inflammation, swelling, or discharge. If erythema or pus develops, initiate appropriate antibiotic therapy based on veterinary guidance.
Monitor the herd for tick‑borne diseases, including anaplasmosis and babesiosis. Conduct periodic blood tests to detect early infection and implement targeted treatment if required.

Effective management combines mechanical removal, chemical control, wound hygiene, and vigilant health surveillance. This integrated approach safeguards the animal’s welfare and minimizes economic losses.

Prevention and Long-Term Management

Tick Control Strategies

Environmental Management

Tick infestation on bovine livestock creates immediate health concerns and long‑term environmental impacts. Effective management requires coordinated actions that reduce tick populations while preserving pasture ecosystems.

Key environmental management measures include:

Rotational grazing to interrupt tick life cycles and reduce host exposure.
Pasture mowing and vegetation trimming to eliminate low‑lying brush where ticks quest for hosts.
Introduction of natural predators, such as certain bird species and parasitic wasps, to suppress tick numbers biologically.
Targeted acaricide application, confined to high‑risk zones and timed to peak tick activity, to minimize chemical runoff.
Regular monitoring of tick density through drag sampling and visual inspections, enabling timely interventions.

Each measure contributes to a sustainable control framework. Rotational grazing limits the duration cattle spend in contaminated areas, while vegetation management reduces microhabitats favorable to ticks. Biological agents maintain ecological balance without excessive pesticide use. Precise acaricide deployment curtails resistance development and protects water quality. Systematic monitoring provides data for adaptive management, ensuring resources focus on emerging hotspots.

Integrating these practices forms an ecosystem‑based strategy that safeguards animal health, protects soil integrity, and supports agricultural productivity.

Topical Treatments

Topical agents provide immediate relief and reduce the risk of secondary infection after a tick bite on a bovine. Application directly to the lesion creates a barrier against bacterial invasion and eases local inflammation.

Effective products include:

Antiseptic solutions containing chlorhexidine or povidone‑iodine, applied with a sterile gauze pad for 30 seconds, then allowed to air dry.
Broad‑spectrum insecticidal creams such as pyrethrin‑based formulations, spread thinly over the attachment site to kill residual tick parts.
Steroid‑containing ointments (e.g., dexamethasone 0.1 %) applied once daily for up to three days to diminish swelling and pain.

Procedure:

Restrain the animal safely; clean the area with lukewarm water to remove debris.
Disinfect with the chosen antiseptic; repeat if visible moisture remains.
Apply the insecticidal or steroid ointment according to the product label, ensuring full coverage of the wound margins.
Monitor the site for signs of worsening inflammation or discharge; repeat antiseptic treatment every 12 hours until healing progresses.

Proper storage of topical preparations—cool, dry environment away from direct sunlight—preserves efficacy. Documentation of the treatment date, product used, and observed response supports herd health records.

Systemic Preventatives

Systemic preventatives are veterinary pharmaceuticals administered orally, by injection, or via feed to provide whole‑body protection against tick‑borne pathogens in cattle. The agents circulate in the bloodstream, killing attached ticks before they can transmit disease.

Common active ingredients include:

ivermectin
doramectin
moxidectin
eprinomectin

Dosage recommendations depend on product formulation and animal weight. Typical regimens involve a single dose of 0.2 mg kg⁻¹ for ivermectin, repeated at intervals of 30–45 days during peak tick activity. Injectable preparations achieve rapid plasma concentrations; oral drenches require thorough mixing with feed to ensure uniform intake. Withdrawal periods must be observed before milk or meat processing.

Systemic agents complement environmental management, such as pasture rotation and acaricide‑treated livestock. Combining approaches reduces tick burden and delays resistance development. Regular inspection of herds allows early detection of treatment failures, prompting rotation to a different class of systemic drug.

Resistance monitoring involves periodic efficacy testing, recording tick mortality rates after treatment, and adjusting protocols accordingly. Maintaining a diversified control program preserves the long‑term effectiveness of systemic preventatives.

Herd Health Management

Regular Inspections

Regular inspections form the cornerstone of effective tick‑bite management in cattle. Early detection prevents disease transmission, reduces skin damage, and limits the need for extensive treatment.

Inspections should occur at least once a week during peak tick season and bi‑weekly when activity declines. Each session must include a systematic walk through the herd, focusing on typical attachment sites such as the ears, udder, and lower limbs.

Separate the animal from the group to allow thorough examination.
Part the hair and inspect the skin for engorged or attached ticks.
Remove any found ticks with fine‑tipped forceps, grasping close to the mouthparts.
Disinfect the bite area with an approved antiseptic.
Record the number of ticks, attachment locations, and any lesions in a herd log.

Maintaining detailed records enables trend analysis, informs strategic acaricide applications, and supports veterinary decision‑making. Consistent implementation of these inspection practices safeguards herd health and productivity.

Nutritional Support

When a bovine endures a tick attachment, the immune response and tissue damage increase metabolic demands. Adequate nutrition mitigates stress, supports wound healing, and reduces the risk of secondary infections.

Protein intake should rise to 12‑14 % of dry‑matter intake. High‑quality forages such as alfalfa or clover, supplemented with legume‑based concentrates, provide essential amino acids. Energy density may be enhanced by adding corn grain, barley, or molasses to maintain body condition during the acute phase.

Micronutrients that reinforce immune function include:

Vitamin A – 20 000 IU per kg of feed, sourced from carrot meal or synthetic premix.
Vitamin E – 300 IU per kg, supplied by wheat germ oil or commercial vitamin‑E premix.
Vitamin C – 500 mg per kg, especially valuable for oxidative stress, delivered via ascorbic acid powder.
Selenium – 0.1 ppm, provided through selenium‑yeast or sodium selenite to enhance neutrophil activity.
Zinc and copper – 30‑40 ppm each, incorporated via mineral blocks or fortified mineral mixes.

Electrolyte balance is critical if fever or inflammation induces sweating. A daily electrolyte solution containing sodium, potassium, magnesium, and bicarbonate prevents dehydration and supports cellular function.

Water consumption must be unrestricted; clean, cool water encourages intake and assists toxin elimination. Monitoring feed refusal or reduced rumination signals the need for veterinary assessment.

Implementing the above nutritional adjustments within 24 hours of tick exposure promotes rapid recovery and protects overall herd health.

Vaccinations (if applicable)

When a bovine experiences a tick attachment, immediate attention includes evaluating the need for prophylactic immunization against tick‑borne pathogens.

Vaccines commonly employed to protect cattle from diseases transmitted by ticks encompass:

Theileriosis vaccine, targeting Theileria spp.
Babesiosis vaccine, addressing Babesia spp.
Anaplasmosis vaccine, preventing infection by Anaplasma spp.

Administration timing depends on herd health status and regional disease pressure. Routine immunization programs schedule initial doses before the peak tick season, followed by booster injections at intervals recommended by the manufacturer, typically every 6–12 months. In cases of a recent tick bite, a veterinarian may advise an accelerated booster if serological testing indicates exposure risk.

Vaccination procedures require sterile injection techniques, proper site selection—commonly the neck or shoulder region—and adherence to dosage specifications. Record‑keeping of vaccine batch numbers, dates, and animal identifiers supports traceability and facilitates disease surveillance.

Consultation with a veterinary professional ensures selection of appropriate vaccine formulations, assessment of contraindications, and integration of immunization into an overall tick‑control strategy.

Record Keeping

Date and Location of Bite

Accurate documentation of the bite’s date and location forms the foundation for effective tick‑management in cattle. Recording the exact calendar day, and when possible the precise time, enables correlation with tick activity cycles and informs the timing of acaricide applications.

Essential data elements include:

Calendar date (day, month, year) and, if available, hour of observation.
Geographic coordinates (latitude and longitude) or a clearly defined pasture name.
Description of the micro‑environment (e.g., shaded area, proximity to water, vegetation type).
Weather conditions at the time of discovery (temperature, humidity, recent rainfall).

Standardized recording procedures improve consistency. A physical logbook may contain pre‑printed fields for each element, while electronic herd‑management systems allow rapid entry via mobile devices and automatic GPS capture. Entries should be legible, use uniform date formats (ISO 8601 recommended), and be verified by a second caretaker when possible.

Collected information supports several critical actions. It guides targeted treatment by identifying high‑risk zones, facilitates evaluation of control‑measure efficacy over time, and contributes to regional surveillance programs that track tick‑borne disease emergence.

Treatment Administered

When a bovine presents a tick attachment, immediate intervention prevents local irritation and systemic disease.

The first response includes:

Gentle extraction of the tick using fine‑point forceps; grasp the mouthparts close to the skin and pull straight upward to avoid fragmentation.
Application of a sterile antiseptic solution (e.g., iodine or chlorhexidine) to the puncture site.
Observation of the wound for hemorrhage; apply a clean dressing if bleeding persists.

Pharmacological measures follow the removal:

Administration of a systemic acaricide (e.g., ivermectin, doramectin) according to label dosage to eliminate residual parasites.
If signs of secondary bacterial infection appear, a broad‑spectrum antibiotic (e.g., oxytetracycline) is prescribed, respecting withdrawal periods.
Anti‑inflammatory agents (e.g., flunixin meglumine) may be given to reduce swelling and pain.

Continued care involves:

Daily inspection of the treated area for edema, discharge, or re‑infestation.
Recording of any adverse reactions to medications.
Scheduling a follow‑up examination within 7–10 days to confirm wound healing and parasite clearance.

Observed Symptoms and Outcomes

A tick attachment on a cow produces a recognizable set of clinical signs.

Localized swelling or a small, raised nodule at the bite site.
Redness and heat around the lesion, sometimes with a crusted scab.
Sudden increase in body temperature, often exceeding 39 °C.
Pale mucous membranes indicating early anemia.
Decrease in milk production, sometimes by 10‑20 % within days.
Reduced feed intake and visible lethargy.

If the infestation progresses, several outcomes may develop.

Transmission of Babesia spp., leading to hemolytic anemia, hemoglobinuria, and potentially fatal collapse.
Introduction of Anaplasma marginale, causing chronic anemia, weight loss, and intermittent fever spikes.
Tick‑induced paralysis due to neurotoxic saliva, manifested by hind‑limb weakness progressing to recumbency.
Secondary bacterial infection of the bite wound, presenting as purulent discharge and worsening inflammation.

Prompt identification of these symptoms enables early intervention, reducing the risk of severe disease and mortality. «Effective treatment hinges on rapid tick removal and appropriate antimicrobial or antiparasitic therapy».
