摘要

This experiment explored the effects of different proportions of sweet sorghum silage as a substitute for corn silage on dry matter intake (DMI), milk yield, milk quality, apparent digestibility, rumen fermentation parameters, serum amino acid profile, and rumen microbial composition of dairy cows. A total of 32 mid-lactation Holstein dairy cows with similar body weights and parities were randomly divided into four treatments: 100% corn silage +0% sorghum silage (CON), 75% corn silage +25% sorghum silage (CS1), 50% corn silage +50% sorghum silage (CS2), and 25% corn silage +75% sorghum silage (CS3). The milk yield was increased (linear, p = .048) as the proportion of sweet sorghum increased. Linear (p = .003) and quadratic (p = .046) increased effects were observed in milk fat as corn silage was replaced with sorghum silage. Compared with the CON diet group, the CS2 and CS3 diet groups had lower dry matter (DM) (linear, p p p = .001) digestibility of the dairy cows. The ruminal fluid aspartate (Asp) level decreased (linear, p = .003) as the proportion of sweet sorghum increased. Linear (p p Faecalibacterium, Bacteroides, and Prevotella ruminicola content/copy number than those fed the CON diet (p < .05). In conclusion, feeding sorghum silage as a replacement for corn silage could increase the milk yield and fat, promote the growth of rumen microbes, and provide more rumen fluid amino acids for the body and microbial utilization. We believe that sorghum silage is feasible for dairy cows, and it is reasonable to replace corn silage with 75% sorghum silage.

该实验探索了不同比例的甜高粱青灰岩的影响，代替了干物质摄入量（DMI），牛奶产量，牛奶质量，明显的消化率，瘤胃发酵参数，血清氨基酸剖面和乳头微生物组成牛。总共32次乳化荷斯坦奶牛具有相似体重和平等的奶牛被随机分为四种治疗方法：100％玉米青贮饲料 +0％高粱青贮饲料（con），75％玉米青贮饲料 +25％高粱青贮饲料（CS1），50％玉米青贮饲料 +50％高粱青贮饲料（CS2）和25％的玉米青贮饲料 +75％高粱青贮饲料（CS3）。随着甜高粱的比例增加，牛奶产量增加（线性，p = .048）。线性（p = .003）和二次（p = .046）在牛奶脂肪中观察到了增加的影响，因为玉米青贮饲料用高粱青贮饲料代替。与CON饮食组相比，CS2和CS3饮食组的干物质（DM）较低（线性，P p p = .001）的奶牛消化率。随着甜高粱的比例增加，瘤胃液天冬氨酸（ASP）水平降低（线性，p = .003）。线性（P P P比喂食饮食的P faecalibacterium，细菌和Prevotella ruminicola含量/拷贝数（P <.05）。总而言之，将高粱青贮饲料作为替代玉米的牛奶产量和脂肪的替代可能会增加牛奶的产量和脂肪，促进瘤胃微生物的生长，并为人体和微生物利用提供更多瘤胃液氨基酸。我们认为，高粱青贮饲料对于奶牛是可行的，并且可以用75％的高粱青贮饲料代替玉米卷。
