Seasonal Influences on Parasitism
Lambing when parasites are less active is often suggested as a means of controlling parasites. USDA researchers in Arkansas compared parasitism in Katahdin lambs born in the winter (Jan-Feb) vs. those born in the fall (Oct-Nov). Body weights and FAMACHA© scores were determined at approximately 60, 90, 120, and 150 days of age. Fecal egg counts and packed cell volumes were determined at approximately 90, 120, and 150 d of age. Lambs were dewormed if their FAMACHA© score was
Combo Treatment Remains Effective
Combination treatments are now recommended for clinically parasitized sheep/goats, but what happens if you give them for several years? Argentinian researchers evaluated the efficacy of a combination treatment, given continuously over a 4 year period. Forty lambs were divided into four groups (n=10): control (no treatment), moxidectin (MOX), levamisole LEV), and moxidectin + levamisole (MOX + LEV). Drugs were injected subcutaneously. MOX and LEV were administered separatel
