No Benefit to Ewe Supplementation

For two years in New Zealand, ewes either grazed pasture alone or were supplemented daily for the first four weeks of lactation with 0.5 kg (1.1 lbs) of a high protein pellet. Supplementation did not affect ewe live weight or body condition score or weight of lamb weaned per ewe. Ewe fecal egg counts (FEC) showed a time x supplementation interaction, being reduced by 50% from week six of lactation in both years. After weaning, there was no consistent parasitological benefit to lambs grazing areas where ewes had been supplemented that were reflected in either pasture larvae concentrations, lamb FEC, requirement for anthelmintic treatment, or lamb growth rate. Despite supplementation of ewes d

2019 NAHMS Goat Study

Anthelmintic resistance testing will be part of the 2019 NAHMS Goat Study. In a cooperative agreement between Louisiana State University and USDA APHIS, the study will evaluate the use of anthelmintics on US goat operations and the prevalence of anthelmintic resistance in goat parasite populations in the US. The study will consist of questionnaires and multiple biological components, with the GIN component expected to be the largest incentive for participating operations. A total of approximately 700 goat operations will be targeted with about 4,500 goats expected to be sampled. Read Timely Topic by Dr. Jim Miller
