中文摘要:

      [目的]研究在奶牛中应用膨胀颗粒饲料对生产性能、血液生化指标及营养物质消化率的影响.[方法]试验选用42头中国荷斯坦奶牛进行为期30 d的饲养试验和为期7天的消化试验,[结果]表明膨胀颗粒饲料能显著提高血清中葡萄糖的含量(P＜0.05);显著降低乳中固形物率(P＜0.05).[结论]膨胀颗粒饲料对产奶量、饲料转化率和营养物质的表观消化率均有提高作用,虽差异不显著,但仍具有一定的经济效益.

英文摘要:

      Forty-two China Holstein cows were used to investigate the effects of expanded-pellets on dairy cow.Results showed that the expanded-pellets could improve the glucose content and reduce the total solids content of milk significantly(P<0.05).Expanded-pellets can improve the milk production,blood biochemical parameters and appearance digestibillity.Though the results were not significant in statistics,there were some economical benefits.
