Injectable Fluke and Worm Housing Treatment

October 30, 2019
Injectable Fluke and Worm Housing Treatment
This week’s Farm Health First #sixtysecondsolutions vlog covers proper use of combination products at housing, with a focus on Animec Super.

While farmers should avoid repeated use of the same active ingredients, injectable formulations can be attractive from a labour point of view versus drenches. As farmers in the UK and Ireland will have multiple parasite species to contend with this housing season, combination products are often also desirable – further reducing potential labour and animal handlings.

That being said, there is no single product that will eradicate all the potential parasites and/or parasite stages in one silver bullet treatment. When using combination products it’s also important to select the right one for your farm.

The combination of ivermectin (effective against internal worms and external parasites) and clorsulon (effective against adult liver fluke) has been sold as an injectable for a number of years and Animec Super is a popular brand.

It is an ideal housing treatment for a drystock farm with a relatively low fluke risk this year. Use Animec Super at housing and follow up with a faecal sample from a number of animals, or drench with an adult flukicide, e.g. Rumenil, prior to turnout.

On a farm with a high fluke risk this housing season, it maybe better advised to opt for a triclabendazole product at housing, e.g. Tribex 10%, to eradicate immature fluke that may be actively damaging livers and would not be killed by clorsulon. A topical ivermectin such as Animec Pour On can be used in conjunction with this to achieve a good parasite coverage at housing.

Depending on variables like prevailing temperatures this winter, subsequent contact with untreated animals post-dosing and shed environments, it may be advised to use a synthetic pyrethroid product in the weeks post-treatment to completely eradicate external parasites such as biting lice.

There is a 66-day meat withdrawal on Animec Super.

Animec Super is given as a subcutaneous injection (under the skin) at a dose rate of 1ml/50kg live weight. A 500kg store heifer would receive a 10ml dose and the 250ml pack size would treat 25 of these animals.

When a dose is above 10ml, best practice is to split across both sides of the animal. The easiest way to administer Animec Super is to fill a chute tightly with animals, pull up a clean portion of skin behind the front shoulder and inject into the ‘pocket’ created. Always massage injection sites post-treatment to prevent leakage. Never, ever under dose with Animec Super, or any medicine.

Ideally, a 16 gauge needle, three quarters of an inch long whould be used with Animec Super. Longer needles are better suited to intramuscular administrations, however older animals will have thicker hides to penetrate. If using an auto-injector, ensure connection between bottle and gun is sound, filling correctly and that there are no air bubbles.

On dairy farms (in the UK only), it can be used at drying off but not within 60 days prior to the commencement of lactation.
