摘要
选用产期相近、产仔猪数为10～12个、胎次相同或相近的10窝母猪(长×大)。每窝选取5头体重相近的7日龄仔猪(2.7 kg左右),随机分成5个处理,每个处理1头猪。各处理组精氨酸的添加水平分别为0、125、250、375mg/(kg·d)和500 mg/(kg·d),结果表明:与对照组相比,250 mg/(kg·d)和375 mg/(kg·d)精氨酸添加组仔猪7～14日龄平均日增重分别提高了3.39%和1.49%;14～21日龄仔猪平均日增重分别提高了6.68%和5.33%。精氨酸添加组仔猪内脏器官相对重量高于对照组(P<0.05)。哺乳仔猪精氨酸的最适添加量为250 mg/(kg·d)。
This experiment was designed to investigate the effect of different arginine supplementations on the growth performance of piglets.Ten sows（Landrace×Yorkshire）with the same parity,varieties,similar parturition and litter size were selected.5 7-day old weaned piglets selected from each sow（average weight 2.7 kg）were randomly assigned into 5 treat-ment groups.Arginine supplementation were 0,125,250,375 mg/（kg·d） and 500 mg/（kg·d）.The results indicated that compared with control group,the supplemention of 250 mg/（kg·d） and 375 mg/（kg·d）arginine could enhance average weight gain by 3.39 %,1.49 % for 7 ～ 14 d,and 6.68 %,5.33 % for 14 ～ 21 d.The relative weight of different visceral organs（visceral organ weight：body,g/kg） significantly increased.The experimental results showed that 250 mg/（kg·d） arginine was optimal supplementation for 7 ～ 21 d old piglets.
