To study the interaction between betaine (BET) and soybean hulls (SBH) on growth performance, body composition, and metabolic status of young growing pigs, 24 barrows with initial body weight (BW) of 29.51 ± 3.24 kg were allotted to one of four dietary treatments in a 2 × 2 factorial arrangement with two levels of BET (0 and 1 g/kg) and SBH (0 and 150 g/kg) for 28 days. Pig BW and feed disappearance were recorded at 14-day intervals. Real-time ultrasonic measurements, as well as jugular blood samples, were obtained initially and on day 28 for all pigs. There was no SBH x BET interaction for growth responses. Pig growth was unaffected by BET supplementation. Dietary SBH addition decreased (P < 0.001) growth rate, as well as feed and energy intakes, which resulted in lighter pigs (P < 0.01) at the end of the study. The inclusion of BET in diets without SBH increased (P < 0.05) loin area and fat-free lean gain, whereas the dietary addition of SBH decreased (P ≤ 0.038) body protein and fat contents. Dietary BET supplementation did not impact the metabolic status of pigs, but feeding SBH increased globulin content (P = 0.039) and decreased albumin-to-globulin ratio (P = 0.023). In conclusion, adding supplemental BET to diets with SBH did not alter nutrient partitioning in young growing pigs, but feeding 150 g/kg SBH lead to slow growth rates and metabolic inefficiency.
为研究甜菜碱（BET）与大豆皮（SBH）对生长育肥仔猪生长性能、体成分和代谢状态的相互作用，将24头初始体重（BW）为29.51±3.24千克的公猪按2×2析因设计分配到四种日粮处理组之一，其中BET有两个水平（0和1克/千克），SBH也有两个水平（0和150克/千克），试验期28天。每隔14天记录猪的体重和采食量。在试验开始时和第28天对所有猪进行实时超声测量并采集颈静脉血样。生长反应方面不存在SBH×BET互作效应。补充BET对猪的生长没有影响。日粮中添加SBH降低了（P＜0.001）生长速度、采食量和能量摄入量，导致试验结束时猪体重较轻（P＜0.01）。在不添加SBH的日粮中添加BET增加了（P＜0.05）腰部面积和无脂瘦肉增重，而日粮中添加SBH降低了（P≤0.038）体蛋白和脂肪含量。日粮中补充BET对猪的代谢状态没有影响，但饲喂SBH增加了球蛋白含量（P = 0.039）并降低了白蛋白与球蛋白的比值（P = 0.023）。总之，在含SBH的日粮中添加补充型BET不会改变生长育肥仔猪的养分分配，但饲喂150克/千克SBH会导致生长速度缓慢和代谢效率低下。
