Fish meal was compared with soybean meal in three trials. In trial 1, 20 early lactation cows fed 70% alfalfa silage received an average .46 kg of CP/d from either source in 2 x 2 Latin squares. Rumen protein escapes estimated in vitro were 37% (soybean meal) and 60% (fish meal). Fish meal increased BW gain, milk protein content, yield of milk, FCM, protein, and lactose; lowered Nmen propionate; and increased rumen acetate:propionate. In trial 2, 32 midlactation cows fed 89% alfalfa silage were… CONTINUE READING
