本研究的目的是调查的影响，饮食补充与多菌株益生菌（MSP）产品含有双歧杆菌动物，干酪乳杆菌，粪链球菌，和啤酒芽孢杆菌的生长，健康，和粪便细菌组成的乳牛在第一个月的生活。将40头2日龄荷斯坦犊牛（24头雌性和16头雄性）按性别和出生日期分组，然后随机分为4组：每天每头犊牛添加0 g（0 MSP）、2 g（2 MSP）、4 g（4 MSP）和6 g（6 MSP）MSP的牛奶添加剂。在30 d期间，添加MSP未导致犊牛体尺参数的任何显著差异。随着MSP剂量的增加，犊牛的平均日增重（p = 0.025）和总干物质采食量（p = 0.020）呈线性增加。2MSP、4MSP和6MSP组小牛的粪便稠度指数低于0MSP组小牛（p = 0.003）。随着MSP剂量的增加，血清中乳酸脱氢酶（p = 0.068）和天冬氨酸转氨酶（p = 0.081）的浓度呈下降趋势，而总胆固醇浓度呈二次曲线增加（p = 0.021）。2MSP、4MSP和6MSP组小牛粪便中Dorea的相对丰度低于0MSP组小牛（p = 0.011）。Dorea（p = 0.001）、粪杆菌（p = 0.050）和Mitsuokella（p = 0.030）的相对丰度线性降低，而Prevotella的相对丰度随着MSP剂量的增加而趋于线性增加（p = 0.058）。在商品化生产条件下，MSP产品可减少新生犊牛腹泻，改善生产性能，并可改变新生犊牛粪便细菌组成。
The aim of this study was to investigate the effects of dietary supplementation with a multi-strain probiotic (MSP) product containing of Bifidobacterium animalis, Lactobacillus casei, Streptococcus faecalis, and Bacillus cerevisiae on growth, health, and fecal bacterial composition of dairy calves during the first month of life. Forty Holstein calves (24 female and 16 male) at 2 d of age were grouped by sex and date of birth then randomly assigned to 1 of 4 treatments: milk replacer supplementation with 0 g (0MSP), 2 g (2MSP), 4 g (4MSP), and 6 g (6MSP) MSP per calf per day. Supplementation of MSP did not result in any significant differences in parameters of body measurements of calves during the 30 d period. As the dosage of MSP increased, the average daily gain (p = 0.025) and total dry matter intake (p = 0.020) of calves showed a linear increase. The fecal consistency index of the 2MSP, 4MSP, and 6MSP group calves were lower than that of the 0MSP group calves (p = 0.003). As the dosage of MSP increased, the concentrations of lactate dehydrogenase (p = 0.068) and aspartate aminotransferase (p = 0.081) in serum tended to decrease, whereas the concentration of total cholesterol increased quadratically (p = 0.021). The relative abundance of Dorea in feces was lower (p = 0.011) in the 2MSP, 4MSP, and 6MSP group calves than that in the 0MSP group calves. The relative abundance of Dorea (p = 0.001), Faecalibacterium (p = 0.050), and Mitsuokella (p = 0.030) decreased linearly, whereas the relative abundance of Prevotella tended to increase linearly as the dosage of MSP increased (p = 0.058). The MSP product can be used to reduce the diarrhea, improve the performance, and alter the composition of the fecal bacteria in neonatal dairy calves under the commercial conditions.
