1. At such times it may be necessary to use an anthelmintic at intervals of 2-4 weeks depending on the degree of challenge.
2. Anthelmintic treatment and move to safe pasture in mid-July
3. Therefore if calves grazed from early spring are given an anthelmintic treatment in early July and moved immediately to a second pasture such as silage or hay aftermath, the level of infection which develops on the second pasture will be low.
4. In Type II the prevalence of clinical disease is comparatively low and often only a proportion of animals in the group are affected; mortality in such animals is very high unless early treatment with an anthelmintic effective against both arrested and developing larval stages is instituted.
5. Prophylactic anthelmintic medication
6. Apart from anthelmintic prophylaxis some studies, especially in Kenya, have indicated the potential value of some indigenous breeds of sheep which seem to be naturally highly resistant to H. contortus infection.
7. The diagnosis of chronic haemonchosis is more difficult because of the concurrent presence of poor nutrition and confirmation may have to depend on the gradual disappearance of the syndrome after anthelmintic treatment.
8. With this system, effective anthelmintic treatment at housing is also necessary using a drug effective against hypobiotic larvae in order to prevent Type II disease.
9. Although burdens of adult Ostertagia spp. in dairy cows are usually low there is some evidence that a single anthelmintic treatment of such cows at, or soon after, calving can improve milk yields.
10. The timing of the move to other pastures may be dependent on other farming activities, but if it can be delayed until October or later and accompanied by an anthelmintic treatment then eggs from any worms which survive the treatment are unlikely to develop due to the unfavourable winter temperatures.
11. Alternatively, a rumen bolus has been recently developed which releases the anthelmintic morantel over a 90 day period.
12. The pathogenesis, diagnosis, treatment and control measures are as for the other ruminants, but care must be taken in choosing the anthelmintic since many of those recommended for sheep and cattle are not registered for use in goats.
13. Anthelmintic prophylaxis has the advantage that animals can be grazed throughout the year on the same pasture and is particularly advantageous for the small heavily stocked farm where grazing is limited.
