- ... A study was conducted to determine effects of grazing of mixed grass/forb pastures at three stocking rates (SR) on subsequent performance of goats and sheep fed a concentrate-based diet. Experimental periods, in 2002 and 2003, were 15 weeks in length, following 16 weeks of grazing (May to September) of pastures with warm season grasses and various forbs. Sheep (Katahdin) and goat (> or =75% Boer b ...

- ... Our objective was to determine the influence of short-term exposure to endophyte-infected tall fescue on reproductive function of ram lambs. Rams (214 days of age) were fed a diet free of endophyte-infected fescue seed (EF; n = 8) or endophyte-infected fescue seed (EI; n = 9; 34% of diet; 4.8 μg g-1 ergovaline) for 6 weeks. Feed offered to EF rams, individually fed, was reduced to the average inta ...
