| 摘 要： | 目的]观察饲喂微生物发酵后的发酵湿料对泌乳期荷斯坦奶牛产奶量及其对饲料消化率的影响。方法]选用全群泌乳期奶牛,按试验目的均匀分为4组,分别为新高产空白组(1组)、新高产试验组(2组)、中低产空白组(3组)、中低产试验组(4组)。新高产试验组(2组)和中低产试验组(4组)每头牛每天饲喂2kg的发酵湿料,新高产空白组(1组)和中低产空白组(3组)不饲喂发酵湿料。结果]发酵湿料对泌乳期荷斯坦奶牛产奶量有明显影响(P<0.05);新高产试验组(2组)奶牛采食量高于新高产空白组(1组);粪筛数据显示,试验组与空白组相比,粪筛第一层比例普遍低2.80%~4.89%。结论]泌乳期荷斯坦奶牛饲喂发酵湿料可显著提高奶牛产奶量及其对饲料的消化率。

| Abstract: | Objective]To evaluate the effect of microbial fermented-wet feed on milk yield and nutrient digestibility of Holstein cows.Method]Cows were divided into four groups according to their milking capacity. Group 1 and group 2 were composed of high-producing cows, whereas group 3 and group 4 were composed of moderate- and low- producing cows. The group 2 and group 4 were set as experimental groups whose basal diet were supplemented with 2 kg fermented-wet feed per day. The group 1 and group 3, serving as control groups, were fed with basal diet without addition of fermented-wet feed.Result] Significant effect of fermented-wet feed on milk yield of Holstein cows was observed (P<0.05);group 2 had higher feed intake compared to group 1;manure screener data showed that the percent of top screen of the experimental groups was generally reduced by 2.80% to 4.89% compared to group 1.Conclusion] Dietary supplementation of fermented-wet feed in lactating period can significantly improve the milk yield and nutrient digestibility of Holstein cows. |
