Abstract
In 2 double switchback trials with 12 cows each, pelleted or nonpelleted cottonseed hulls were substituted for 10, 30 or 50% of the alfalfa hay cubes in a ration containing 50% alfalfa hay cubes and 50% high-energy concentrate. No differences due to diet were detected in total milk production, percents fat, protein, solids-not-fat or fatty acids in milk. Digestibilities of protein, acid detergent fiber and combustible energy but not fat were depressed progressively as cottonseed hulls increased in the diet.
