What are the signs and effects of livestock infected with parasites?


Signs and effects of infected livestock

Infection:Gut Worm

Symptoms: Diarrhoea, decreased appetite, loss of weight

Effects: Gutworm can cause severe damage to the stomach and small intestine which will cause parasitic gastroenteritis, this will not only negatively affect the health of the animal but will affect the profitability for the farmer.

Infection: Lungworm

Symptoms:Short, sharp cough that becomes worse with exercise, in severe cases the animal will have obvious difficulty breathing.

Effects:Lungworm infections cause a high susceptibility to respiratory viruses and bacteria. Infected cattle are prone to contracting severe bronchial pneumonia which if left untreated can lead to death.

4.1 Target Species


4.2 Indications for use, specifying the target species

In cattle:
For the treatment of infections with the following parasites

Gastro-intestinal worms
- Haemonchus placei (adult and L4)
Ostertagia ostertagi (adult and L4, including inhibited larvae)
Trichostrongylus axei (adult and L4)
Trichostrongylus colubriformis (adult and L4)
Cooperia punctata (adult only)
Cooperia oncophora (adult only)
Strongyloides papillosus (adult only)
Oesophagostomum radiatum, (adult and L4)

Lungworm (adult and L4)–
Dictyocaulus viviparus.

Warbles (parasitic stages) –
Hypoderma bovis,
Hypoderma lineatum.

Mange mites
Sarcoptes scabiei var. bovis.

The product may also be used to reduce infection of the mange mite Chorioptes bovis, but complete elimination may not occur.

Sucking and biting lice
Linognathus vituli,
Haematopinus eurysternus,
Bovicola (Damalinia) bovis.

The product has persistent activity against infections acquired with Trichostrongylus axei and Cooperia spp. up to 14 days after treatment, but only in the case of group treatment;
Ostertagia ostertagi and Oesophagostomum radiatum up to 21 days after treatment;
Dictyocaulus viviparus up to 28 days after treatment.
It also has persistent activity against horn flies (Haematobia irritans) for up to 28 days after treatment;
partial efficacy against Haematobia irritans may last for up to 35 days post application. 

4.3 Contraindications

Do not use in cases of known hypersensitivity to the active ingredient.
The product has been formulated for topical application specifically for cattle.
It should not be administered to other species as severe adverse reactions including fatalities in dogs, may occur.

4.4 Special warnings for each target species

Do not treat cattle when their hide is wet.
Do not treat cattle if rain is expected, as rain within 2 hours of treatment may reduce efficacy.
Do not apply to areas of skin which have mange scabs or other lesions, or to areas contaminated with mud or manure.

Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in ineffective therapy:
-Too frequent and repeated use of anthelmintics from the same class, over an extended period of time.
-Underdosing, which may be due to underestimation of body weight, misadministration of the product, or lack of calibration of the dosing device.

Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. Faecal Egg Count Reduction Test). Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.
Resistance to ivermectin has been reported in Ostertagia ostertagi in cattle. Therefore, the use of this product should be based on local (regional, farm) epidemiological information about susceptibility of this helminth species and recommendations on how to limit further selection for resistance to anthelmintics.

4.5 Special precautions for use Special precautions for use in animals

To avoid secondary reactions due to the death of Hypoderma larvae in the oesophagus or in the spine, it is recommended to administer the product at the end of warble fly activity and before the larvae reach their resting sites. Cases of intolerance with fatal outcome are reported in dogs, especially Collies, old English Sheepdogs and related breeds or crosses, and also in turtles/tortoises.
Do not allow these species to come in contact with this product.
It is recommended to treat all animals within a herd or group.
The shedding of nematode eggs can continue for some time after treatment.
Close container after use.

Special precautions to be taken by the person administering the veterinary medicinal product to animals

May be irritating to human skin and eyes and the user should be careful not to apply it to himself or other persons. Operators should wear rubber gloves, boots, goggles and a waterproof coat when applying the product.
Protective clothing should be washed after use.
As absorption through skin can occur, in the event of accidental skin contact, wash the affected area immediately with soap and water.
If accidental eye exposure occurs, flush the eyes immediately with water and get medical attention.
Do not smoke, eat or drink while handling the product.
Wash hands after use.
Use only in well ventilated areas or outdoors.

HIGHLY INFLAMMABLE, keep away from heat, sparks, open flame or other sources of ignition.

4.6 Adverse reactions (frequency and seriousness)

None known.

4.7 Use during pregnancy, lactation or lay

Studies in laboratory animals have shown neither embryotoxic nor teratogenic effects with ivermectin. Can be used during pregnancy and lactation provided that the milk is not intended for human consumption. Please also see section 4.11

4.8 Interaction with other medicinal products and other forms of interactions

Do not combine ivermectin treatment with vaccination against lungworms.
If vaccinated animals are to be treated, treatment should not be carried out within a period of 28 days before or after vaccination.

4.9 Amounts to be administered and administration route

To ensure administration of a correct dose, body weight should be determined as accurately as possible. If animals are to be treated collectively rather than individually they should be grouped according to their bodyweight and dosed accordingly, in order to avoid under- or over- dosing.

Dosage 1 ml per 10 kg body weight (based on a recommended dosage level of 500 micrograms per kg body weight).

For topical application.
The formulation should be applied along the mid-line of the back in a narrow strip between the withers and tailhead.

The 250 ml and 1.0 litre packs must be used with appropriate dosing equipment. Instructions for using the dispensing chamber:
a) Take dip tube and insert end into base of measuring cap with slotted end going to the bottom of the container.
b) Remove shipping cap from container.
c) Screw measuring cap onto container.
d) Select the correct dose rate by rotating the adjuster cap in either direction to position the dose indicator to the appropriate dose.
e) Gently squeeze the bottle to fill to level (any excess will return to the bottle) and then tip and apply to animal along backline.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

No signs of toxicity appeared in trials up to 3 times the recommended dose rate.
Clinical symptoms of ivermectin toxicity include ataxia and depression.
No antidote has been identified.

ATC vet code:


Pharmacotherapeutic group:


5.1 Pharmacodynamic properties

Ivermectin is a mixture of two compounds belonging to the avermectin family, which are a macrocyclic lactone group of endectocides. Avermectin is a microbial metabolite of the soil organism Streptomyces avermilitis. 

It is generally accepted that ivermectin exerts its action in two main ways, interference with neurotransmission and opening chloride ion channels.
The effect of ivermectin on the parasitic CNS is considered to operate through glutamate-mediated chloride channels. Compounds of this class may also interact with other ligand-gated chloride channels, such as those gated by the neurotransmitter gamma-aminobutyric acid (GABA).
The opening of pre-synaptic chloride ion channels results in an efflux of chloride ions and depolarisation of the nerve terminal. These effects interfere with normal neurotransmission between nerves and muscles, resulting in parasite paralysis and eventual death.

5.2 Pharmacokinetic particulars

After administration of the product, the ivermectin is absorbed through the skin into the circulation of the treated animal. The maximum concentration in plasma occurs around 70 hours after application. Peak concentrations of about 7 ng/ml are obtained. The residual antiparasitic effect of ivermectin is due to its persistence, which in turn is due in part to its long intrinsic half-life (t1/2β of approximately 210 hours), in part to its relatively high plasma protein binding (80% in cattle; binding remains relatively constant over time) and in part to the nature and type of the ivermectin formulation.


is in the faeces (via biliary excretion).
Over 60% of the dose is excreted after 3 days.
