Alternative Housing and Management for Organic Dairy Production
Organic cows (n = 57) were used to evaluate activity, rumination time and their correlation with pasture fly activity of cows fed 3 grain supplementation strategies during the grazing season from May to September 2013. Cows were assigned to 1 of 3 replicate supplementation groups: 1) no corn grain …
