Abstract：
The study aimed to evaluate the effect of maternal or formulated transition milk with colostrum powder on the performance and health of dairy calves. After receiving 12% of their birth weight in high-quality colostrum, 36 Holstein calves (17 males and 19 females) were blocked according to sex, birth date and birth weight (29.16 kg ± 1.34) and randomly distributed into three treatments: (1) Milk: supplying 4 L/d of whole milk (WM) for three days (n = 12); (2) Transition milk (TM): supplying 4 L/d of maternal transition milk for three days (n = 12); (3) Formulated transition milk (FTM): supplying 4 L/d of whole milk enriched with 280 g/d of colostrum powder, for three days (n = 12). Daily feeding was split into two feedings, and after the sixth feeding of the transition diet calves were fed 6 L/d of whole milk and had ad libitum access to water and calf starter until 56 d, when the study ended. Calves fed TM or FTM presented a higher total solids intake (p < 0.05). Concentrations of glucose (p = 0.096) and lactate (p = 0.063), evaluated from 0 h to 72 h, tended to be higher in WM-fed calves compared to TM. There were no effects on calf\'s health or performance and weight; at the week 8 averaged 65.06 kg ± 1.85. All treatments resulted in adequate performance and good health, however, the potential benefits of providing TM or FTM were not seen in this study. The transition milk composition and the number of meals after colostrum feeding need more investigation.
摘要：
该研究旨在评估母体或配方过渡乳与初乳粉对奶牛生产性能和健康的影响。在优质初乳中接受12％的出生体重后，36头荷斯坦小牛（17头雄性和19头雌性）根据性别被封锁，出生日期和出生体重（29.16kg±1.34），随机分为三种处理：（1）牛奶：供应4L/d全脂牛奶（WM）三天（n=12）；（2）过渡牛奶（TM）：供应4L/d母体过渡牛奶三天（n=12）；（3）配方过渡牛奶（FTM）：供应4L/d全脂牛奶，富含280g/d的乳粉，三天（n=12）。每日喂食分为两次喂食，在第六次饲喂过渡饮食小牛后，饲喂6升/天的全脂牛奶，并随意取水和小牛发酵剂，直到56天，当研究结束时。饲喂TM或FTM的小牛呈现较高的总固体摄入量(p<0.05)。葡萄糖（p=0.096）和乳酸（p=0.063）的浓度，从0小时到72小时评估，与TM相比，WM喂养的小牛往往更高。对小牛的健康或性能和体重没有影响;在第8周平均65.06kg±1.85。所有的治疗都带来了足够的表现和良好的健康状况，然而,在这项研究中,未发现提供TM或FTM的潜在益处.初乳喂养后的过渡乳成分和餐数需要更多的调查。
