摘要
选择30头28日龄断奶的DLY仔猪,平均体重(8.22±0.31)kg,按体重、性别、品种一致原则随机分为3个处理,每个处理10个重复,每个重复1头猪,分别饲喂可消化赖氨酸水平相同,蛋白水平分别为17.0%、19.0%、21.0%的三种不同日粮,考察不同蛋白水平对仔猪生产性能和营养物质消化率的影响。试验结果表明:在氨基酸水平与模式一致时,日粮中蛋白水平对仔猪生长性能没有明显差异,以日粮中蛋白质水平为19%时,乳猪的生长性能最佳。
A single factor design was conducted to explore the effects of protein at 3 doses on growth performance and nutrients digestibility in weaned piglets. 30 DLY weaned piglets of （8.2＋0.30） kg of body weight were distributed in a completely randomized into 3 treatments with 10 replicates of 1 weaned piglet. The level of protein was 17.0%, 19.0%, and 21.0% respectively. The results of this ex- periment showed： the level of protein had no negative influence on growth performance of weaned piglet, when the model and dose of amino acid in diet were same. But growth performance of weaned piglet tends to be best at 19.0% of protein.
