It Starts with Genetics

For sheep producers with flocks on pasture, controlling internal parasites can be expensive and time-consuming, but the cost of not controlling the parasites can be even greater, in reduced performance and death losses. While it won’t eliminate the need to monitor and deworm entirely, building a flock with greater genetic resistance can help reduce losses and treatment expenses. John Anderson, who raises Polypay sheep seedstock in Ohio has been selectively breeding for parasite resistance for 10 years, and he’s seeing the benefits in his own flock and in the breeding stock he sells.

Study to Access Efficacy of Ivermectin Against Covid-19

Clínica Universidad de Navarra and the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, have launched a clinical trial to investigate the efficacy of ivermectin against COVID-19. The aim of the study, carried out in collaboration with Idifarma, is to determine whether administration of ivermectin is associated with a shorter viral clearance time. Ivermectin was recently shown to inhibit the replication of SARS-CoV-2 in vitro at very high doses, but this effect has not yet been studied in vivo. The new study will investigate this question in a randomised trial with twenty-four patients with mild disease and no risk factors. Read full article

Weighing Sheep and Goats

Don't have a scale? You can use measurements to estimate the weight of a sheep or goat. It's not as good as a scale, but better than guessing. It is important that dewormer doses be based on accurate weights. Underdosing is one of the contributing factors to anthelmintic resistance.

Texas A&M AgriLife FEC Testing

Texas A&M AgriLife is now offering fecal egg count testing to help sheep and goat breeders quantify natural resistance to internal parasites. Testing is most useful when the data is used to develop EBVs through the National Sheep Improvement Program (NSIP). The price is $5 per sample. Results will be returned within 7 business days of arrival. View collection procedure: Several other ACSRPC members with laboratories are offering affordable fecal egg testing for the purpose of genetic evaluation or fecal egg count reduction.
