摘要
The aim of this study was to evaluate butyrate supplementation of antibiotic‐free milk replacer and starter on growth performance in male Holstein calves. Twenty‐nine calves were divided into two groups. Group C (n = 13) was fed antibiotic‐free milk replacer without supplementation, and Group B (n = 16) was fed antibiotic‐free milk replacer supplemented with butyrate (1.6 % DM of Gustor BP70®). Starter in Group B contained 0.3 % DM of Gustor BP70®. The intake of milk replacer was lower in group B than in C (p = 0.07 for the treatment x week interaction). Body weight (BW) and heart girth (HG) in group B was higher than in C during the experimental period (p = 0.07 and 0.01 for the treatment × week interaction, respectively). The duration of the weaning period in group B was shorter than in group C (p = 0.02). β‐hydroxybutyrate (BHBA) was higher in group B than in C (p = 0.04). Insulin like growth factor‐1 (IGF‐1) concentrations tended to be higher in group B than in C (p = 0.07 for treatment × week interaction). Our results show that butyrate supplementation in antibiotic‐free milk replacer and starter exerted positive effects on growth performance in suckling calves.

本研究的目的是评估丁酸盐补充无抗生素的代乳品和起子对雄性荷斯坦牛犊的生长性能。将29只小牛分成两组。 C组（n \x3d 13）喂食无抗生素的代乳粉，无需补充，B组的代乳粉摄入量低于C组（治疗x周相互作用p \x3d 0.07）。在实验期间，B组的体重（BW）和心脏周长（HG）高于C组（治疗×周相互作用分别为p \x3d 0.07和0.01）。B组断奶时间短于C组（p \x3d 0.02）。 β-羟基丁酸（BHBA）在B组高于C组（p \x3d 0.04）。B组胰岛素样生长因子-1（IGF-1）浓度往往高于C组（治疗时p \x3d 0.07×周相互作用）。我们的研究结果表明，在无抗生素的代乳品和起子中添加丁酸盐对哺乳小牛的生长性能产生了积极影响。
