摘要: This study assessed whether harvest time and microbial anaerobic fermentation could affect ruminal degradability intestinal digestibility of whole Zhang hybrid millet, estimate the effect fermented millet as feedstuff on milk yield quality. Protein degradation digestion were determined using in situ nylon bag technique three-step vitro method, respectively. Results showed that time, fermentation, or their interaction significantly affected EDDM, EDCP, EDNDF (p 0.05). Microbial provided similar compositions compared with controls, it reduced SCC = 0.04). Milk was numerically higher groups. In conclusion, further improve utilization millet. Whole be an alternative feedstock for dairy cows acceptable safety profile potential benefit production.
