Autoworm First Grazer
Active substance
ATC code
Species
Cattle weighing between 100 kg and 400 kg
Indications
For administration to cattle weighing between 100 kg and 400 kg at the time the bolus is given. Designed for dosing prior to turnout of cattle in their first grazing season.
In grazing cattle, the device will deliver seven doses of oxfendazole for the treatment of both adult and immature gastro-intestinal roundworms and lungworms and tapeworms at regular intervals of approximately three weeks during a period of approximately 21 weeks, the first dose being released around three weeks after administration. The device thus delivers a programmed therapeutic anthelmintic dosing regime over a period of approximately twenty-one weeks.
Oxfendazole is an established treatment for:
Gastro-intestinal roundworms: Telodorsagia (Ostertagia), Haemonchus,
Trichostrongylus, Nematodirus, Cooperia, Capillaria, Oesophagostomum,
Chabertia, Trichuris;
Lungworms: Dictyocaulus viviparus;
Tapeworms: Moniezia, heads and segments.
At the recommended dose rate in cattle, oxfendazole is effective against inhibited/arrested larvae of Cooperia and usually effective against inhibited/arrested larvae of Ostertagia. It is also ovicidal against nematode eggs.
Dose to be administered and administration route
Bodyweight should be determined as accurately as possible.
One bolus should be administered to each calf being turned out to pasture for the first grazing season. Alternatively, one bolus may be administered later in the season - ideally approximately three weeks before the first anthelmintic dose is normally required, or approximately one week before a move to pasture which has previously been contaminated by worm eggs.
Lungworm infestations which develop during the active life of the bolus and are present at the time of pulsing will be controlled by oxfendazole. Under conditions of very heavy larval challenge, clinical signs of lungworm can become evident within 10 - 14 days of picking up an infection. Therefore, if clinical signs of lungworm occur in treated animals they should be dosed immediately with an appropriate anthelmintic.
Lungworm infestations can sometimes develop during the active life of the bolus.
Administration:
Administer orally using the Autoworm Bolus Applicator which delivers the bolus directly into the top of the gullet. When using the Autowonn Bolus Applicator, insert the bolus into the balling gun with the metal end weight innermost. The applicator should be inserted from the front (not sides) of the mouth and over the back of the tongue, with no more than gentle, firm pressure. As the animal begins to swallow the end of the gun, the passage down the throat becomes easier. The applicator is now in position for firing. Depress the plunger to eject the bolus. Normal care should be taken not to cause injury by placing the gun too far inside the throat of the animal.
Ensure that each animal has swallowed the bolus by observing the animal for a short time after dosing.
Adverse reactions
None when used as recommended.
