What is coccidiosis?

Coccidiosis is a highly contagious disease that normally infects calves between one and six months of age but can also infect older cattle as well. 
Coccidiosis is caused by a single celled microscopic parasite that multiplies in the intestine of infected animals, the eggs are then passed through faeces onto the soil and grass where they are eaten by other animals which then become infected. 
Coccidiosis is still one of the most common and costly diseases a farmer can face on his farm.

What are the symptoms of Coccidiosis?

Common symptoms of Coccidiosis are diarrhoea, rough coat, loss of appetite, loss of weight and weakness in calves. In severe cases there will be blood and mucus present in the animals manure and if left untreated will lead to the animal's death.

White, oral suspension.

4.1 Target Species

Ovine (lambs) and bovine (calves).

4.2 Indications for use, specifying the target species
In lambs: Prevention of coccidiosis caused by Eimeria crandallis and Eimeria ovinoidalis.
In calves: Prevention of coccidiosis caused by Eimeria bovis and Eimeria zuernii.
If there is no recent and confirmed history of clinical coccidiosis, the presence of coccidia in the flock or herd should be confirmed by faecal sampling prior to treatment.

4.3 Contraindications
Do not use in cases of hypersensitivity to the active substance or to any of the excipients.

4.4 Special warnings for each target species
Avoid underdosing which may be due to underestimation of body weight, misadministration of the product or lack of calibration of the dosing device (if any).
Calves: in certain cases, only a transient reduction of oocyst shedding may be achieved.
Suspected clinical cases of resistance to anticoccidials 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 antiprotozoal, an anticoccidial belonging to another pharmacological class and having a different mode of action should be used.

4.5 Special precautions for use
Special precautions for use in animals

The preferred timing of treatment is directed by the known epidemiology of Eimeria spp. and the presence of coccidia in the flock or herd should be confirmed by faecal sampling prior to treatment, if there is no recent and confirmed history of clinical coccidiosis. 
Coccidiosis is an indicator of insufficient hygiene in the flock/pen.
It is recommended to improve hygiene and to treat all lambs in the flock and all calves in a pen.
Frequent and repeated use of antiprotozoals may lead to the development of resistance in the target parasite.
To alter the course of an established clinical coccidial infection, in individual animals already showing signs of diarrhoea, additional supportive therapy may be required as diclazuril has no antimicrobial activity.
Special precautions to be taken by the person administering the veterinary medicinal product to animals Wash hands after administration of the product.

4.6 Adverse reactions (frequency and seriousness)
In very rare cases, adverse events involving gastrointestinal disorders (such as diarrhoea, with possible presence of blood), lethargy and/or neurological troubles (agitation, recumbency, paresis...) have been reported.
Some treated animals may show signs of clinical disease (diarrhoea) even though oocyst excretion is reduced to a very low level.
The frequency of adverse reactions is defined using the following convention:
- very common (more than 1 in 10 animals displaying adverse reaction(s) during the course of one treatment)
- common (more than 1 but less than 10 animals in 100 animals)
- uncommon (more than 1 but less than 10 animals in 1,000 animals)
- rare (more than 1 but less than 10 animals in 10,000 animals)
- very rare (less than 1 animal in 10,000 animals, including isolated reports).

4.7 Use during pregnancy, lactation or lay
Not applicable.

4.8 Interaction with other medicinal products and other forms of interactions
None known.

4.9 Amounts to be administered and administration route
Shake well before use.
To ensure a correct dosage, 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 body weight and dosed accordingly, in order to avoid under- or overdosing.
1 mg diclazuril per kg body weight (i.e. 1 ml of the oral suspension per 2.5 kg body weight), in a single oral administration. 

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
In lambs: no signs of overdose were noted after administration of 5 times the recommended dose.
In calves: no signs of overdose were noted after a single administration of 5 times the recommended dose.
In case of repeated administration of 3 to 5 times the dose, on 3 consecutive days, a softening and a colour change (dark brown) of the faeces can be observed in some calves.
These observations were transient and disappeared without specific treatment.

4.11 Withdrawal period(s)
Meat and offal:
Lambs: zero days
Calves: zero days 

Antiprotozoals, Triazines

ATCVet Code:

5.1 Pharmacodynamic properties
Diclazuril is an anticoccidial of the benzeneacetonitrile group and has anticoccidial activity against Eimeria species. Depending on the coccidia species, diclazuril has a coccidiocidal effect on the asexual or sexual stages of the development cycle of the parasite.
Diclazuril treatment will only have limited effect on the intestinal lesions caused by parasitic stages older than 16 days.
Treatment with diclazuril causes interruption of the coccidial cycle and of excretion of oocysts for approximately 2 weeks.
This allows the animal to bridge the period of decrease of maternal immunity (observed at approximately 4 weeks of age).

5.2 Pharmacokinetic particulars
The absorption of diclazuril in lambs is poor after administration of the oral suspension.
Maximum concentrations in plasma are reached about 24 hours after dosing.
The absorption decreases with the animals’ age.
The elimination half-life is about 30 hours.
In-vitro studies on sheep hepatocytes demonstrated that metabolic transformation of diclazuril is limited.
This was equally observed in other animal species.
Excretion occurs almost completely via the faeces.
When diclazuril is administered in oral suspension to calves, its absorption is poor.

Drench correctly
Sheep Oral Drench

The drenching technique is a vital part of ensuring that the wormer does its job effectively.
Make sure the sheep are properly restrained and cannot leap around when they are being drenched so they swallow the whole amount.
Sheep can also suffer serious injury, or even death, if they are unrestrained and the gun penetrates the tissues at the back of the mouth.
Place a hand under the head and tilt slightly to the side.
Slot the nozzle in the gap between molar and incisor teeth and then over the back of the tongue.
If the wormer is just put into the mouth, it will bypass the rumen as it escapes down the oesophageal groove and will be less effective.
This is particularly important for white (BZ) drenches.

Dosing Weigh – do not guess Underestimating the weight of sheep is a common cause of underdosing. Select and weigh the biggest sheep in the group to determine the correct dose. If there is a wide range of weights, consider splitting the group, then weigh the heaviest in each section. Do not forget to check that the weigh crate is accurate before starting!

Calibrate and maintain the drench gun
Always check the gun is delivering the right amount before you drench. Remove the plunger from a 10 ml syringe, put a thumb over the end and squirt the dose into it, making sure there are no air bubbles left. Adjust the gun until the dose delivered is correct. Drenching guns should also be well maintained and replaced regularly. Clean with warm soapy water after use and check springs and tubes to make sure there are no kinks that will form air bubbles.

Withholding food
Research has shown that the efficacy of the white (BZ) and clear (AV) drenches can be improved by withholding food for 12–24 hours before treatment. It is not advised to deprive heavily pregnant ewes of food, so if you treat this class of stock with anthelmintics, you may wish to use yellow drenches (LV) because their efficacy is less dependent on rumen fill.

Wormers should be stored securely, away from direct sunlight at 4–25°C. Check the use-by date and, once open, use within the time shown on the packaging. Shake white (BZ) products well before use.

 Cattle Oral drenches
Oral drenching guns are designed to deliver the treatment towards the back of the mouth over the tongue, so the entire dose is swallowed at once to optimise efficacy.
• Make sure animals are properly restrained, with their head held up
• Slide the nozzle of the dosing gun in the side of the mouth and over the tongue so that the entire dose is swallowed immediately
• Drenching equipment must be correctly calibrated and in good working order
• Calibrate the gun using the product just before treatment starts by delivering two or more doses into a graduated measuring cylinder. 
Faulty equipment, or attempting to dose too quickly, may mean that the barrel of the gun does not fill properly or that the liquid is full of bubbles.
