放牧是一种常见的饲养方法。我们研究了放牧期间补充对牛奶产量和成分的影响,血液生物化学,伊犁马的粪便微生物。控制母马正常放牧,而I组和II组接受1kg/d的浓缩物和1kg/d的浓缩物+0.4kg/d的涂层FA,分别。Ⅰ组和Ⅱ组的奶量明显高于对照组,在前两次中,II组的牛奶量明显高于I组。乳脂,乳糖,II组的蛋白质水平明显高于其他组。I组BUN显著低于对照组。具体FAs,总SFA,II组的总UFA明显高于其他组。喂食后,等离子体GLU,免费FA,TG,LDL,Ⅱ组VLDL显著高于其他组。对照组,I组,第二组有4984、5487和5158个OTU,分别,3483个OTUs是所有组的共同点。拟杆菌和厚壁菌的丰度>75%。I组和II组的Verrucomicrobia的丰度明显高于对照组,在前两次中,II组明显高于I组。对照组和其他组之间的螺旋体_糖原的丰度显着不同,和WCHB1_41,Kiritimatielae,和Verrucomicrobia的丰度在II组和其他组之间显着不同。
Grazing is a common approach to rearing. We investigated the effects of supplementation during grazing on milk yield and composition, blood biochemistry, and fecal microflora in Yili horses. The control mares grazed normally, while those in groups I and II received 1 kg/d of concentrate and 1 kg/d of concentrate + 0.4 kg/d of coated FA, respectively. Milk volumes were significantly higher in groups I and II than in the control group, and among the previous two, milk volumes were significantly higher in group II than in group I. Milk fat, lactose, and protein levels were significantly higher in group II than in the others. BUN was highly significantly lower in group I than in the control group. Specific FAs, total SFA, and total UFA were significantly higher in group II than in the other groups. After feeding, plasma GLU, free FA, TG, LDL, and VLDL were significantly higher in group II than in the other groups. The control group, group I, and group II had 4984, 5487, and 5158 OTUs, respectively, and 3483 OTUs were common to all groups. The abundance of Bacteroidetes and Firmicutes was >75%. The abundance of Verrucomicrobia was significantly higher in groups I and II than in the control group and, among the previous two, significantly higher in group II than in group I. The abundance of Treponema_saccharophilum significantly differed between the control and other groups, and WCHB 1_41, Kiritimatiellae, and Verrucomicrobia abundances significantly differed between groups II and the other groups.
