摘要
Calf starter was offered to 40 calves in a plastic bucket or from a nipple bottle, and intake, growth, and selected blood parameters were measured. The nipple was designed with a large opening to allow feed particles to pass through the nipple during meals. Calves began the study at 7 d of age and were fed for 56 d. A commercially prepared calf starter was offered for ad libitum consumption from d 1 of the study, and commercial milk replacer was offered at 10% of BW to weaning at 6 wk of the study. No effects of treatment on intake, rates of gain, feed efficiency, blood BHBA or plasma glucose, urea N, or NEFA were observed. Consumption of starter DM exceeded 1.9 kg/d by wk 8 of the study. Concentration of blood parameters changed in a fashion consistent with developing ruminal function. Calf starter fed from a plastic nipple bottle promoted starter intake as effectively as did starter fed from plastic buckets.

小牛起子用塑料桶或乳头瓶提供给40只小牛,测量摄入量,生长量和选择的血液参数。乳头设计有一个大开口,允许饲料颗粒在进餐时通过乳头。小牛在7日龄开始研究并喂食56天。从研究的第1天开始,自由采食商业制备的小牛起子,并且在研究的第6周,以10%的BW提供商业代乳品至断奶。没有观察到治疗对摄入,增加率,饲料效率,血液BHBA或血浆葡萄糖,尿素N或NEFA的影响。研究第8周,起始DM消耗量超过1.9 kg / d。血液参数的浓度以与瘤胃功能发展相一致的方式改变。从塑料奶嘴瓶喂养的小牛起动器可以像从塑料桶喂养的起动器一样有效地促进起动器的进气。
