日粮中富含限制性必需氨基酸发酵肽对奶牛产奶量和乳品质的影响
Influence of Feeding Fermented Peptides Rich in Limited Essential Amino Acids on Milk Yield and Quality in Dairy Cows
摘要
Abstract
The objective of.this study was to determine if supplementing fermented peptides rich in limited essential amino acids to daily feed can increase milk yield and quality in Chinese Holstein dairy cows in mid-lactation （180 d）. Using randomized complete block design, 15 Chinese Holstein dairy cows with similar body weight, milk yield and number of births were assigned into three groups： control group, 0.5% supplementation group and 1% supplementation group. The results showed that milk yield （by 11.0% and 13.7%）, protein content （by 5.6% and 6.6%）, fat rate （by 7.0% and 7.5%, respectively） and dry matter rate （by 0.25 % and 0.67 %, respectively） of the 0.5% supplementation and the 1% supplementation groups were all significantly higher those of the control group （P 〈 0.01）. Similarly, milk sugar content was also increased. These findings demonstrate that supplementing fermented peptides rich in limited essential amino acids to daily feed can increase milk yield and quality in dairy cows effectively.关键词
