CONGRATULATIONS to the BVA on producing a poster to encourage a reduction in the use of anthelmintics in grazing animals. Many of us in livestock areas have promoted responsible anthelmintic usage for years.

Veterinary Clinics of North America: Food Animal Practice, 1986
A number of anthelmintics are available for the control of gastrointestinal nematodes in cattle. In North America, O. ostertagi, Cooperia spp., lung worm, and F. hepatica probably cause the greatest losses in production. The older anthelmintics are often deficient in their action against some of these parasites. Recently, the Paratect morantel tartrate

Anthelmintic control of Ostertagia ostertagi in cattle presents some special problems because the arrested larval stage (hypobiotic EL4) tolerates all of the older anthelmintics. The only anthelmintics on the North American market that are effective against this stage as well as the adult and developing stages are ivermectin and fenbendazole.

Anthelmintic Treatment of Uncinariasis
The American Journal of Tropical Medicine and Hygiene, 1954Summary Tetrachlorethylene, U.S.P., when administered without being followed by a purge, causes less shock to the patient and is more efficacious in removing hookworms than when the anthelmintic is followed by a saline purge. A dosage scale of 0.05 cc.

Anthelmintic resistance is widespread in nematode parasites of sheep, goats and horses. Resistance is also developing in nematode parasites of cattle and has been detected in pig parasites. Benzimidazole, levamisole/morantel and ivermectin resistances occur in nematodes of sheep and goats and closantel resistance has been found in Haemonchus contortus.

Since the introduction of broad-spectrum anthelmintics these drugs have been the major means of managed control of nematode parasites. Anthelmintics have been used particularly in livestock for the control of economically important parasites. Because of heavy reliance on these drugs and their widespread use, anthelmintic-resistant parasites have been ...

Since the first reports of resistance to the broad spectrum anthelmintics were made some three decades ago, this phenomenon has changed from being considered merely as a parasitological curiosity to a state of industry crisis in certain livestock sectors. This extreme situation exists with the small ruminant industry of the tropical/sub-tropical region

Veterinary Parasitology, 1993
In populations of livestock in which anthelmintics have become the only means of control, individual worms in some species of helminths evade the effects of specific anthelmintics. If these resistant individuals are selected (by removing the susceptible individuals in the population) then the resistant worm population on individual farms becomes ...

Anthelmintics are drugs used to eradicate helminth infestations of the intestine or tissues of other organs. The most relevant types of chemical classes of anthelmintics are piperazines, benzimidazoles, imidazothiazoles, tetrahydropyrimidines, isoquinolines, salicylanilides, and few sporadic compounds that do not belong to these chemical classes ...
