论文旨在研究日粮中添加不同水平乳铁蛋白(lactoferrin,Lf)对早期断奶仔猪养分利用率、血清营养生化指标及血清酶活性指标的影响.采用单因素试验设计,选用21日龄断奶仔猪96头,随机分为4个处理,每个处理4个重复,每个重复6头仔猪,分别在基础饲粮中添加0、250、500和750 mg/kg乳铁蛋白.试验为期21d.结果表明:添加乳铁蛋白有提高断奶仔猪干物质消化率的趋势(P＞0.05),其中500 mg/kg添加组最高.250 mg/kg、750 mg/kg组与对照组相比能显著提高粗灰分消化率(P＜0.05)；750 mg/kg乳铁蛋白组血清中尿素氮和总胆固醇的含量显著低于对照组(P＜0.05),各乳铁蛋白添加组血清中总蛋白水平有提高的趋势(P＞0.05)...

The experiment was conducted to investigate the effects of supplemental lactoferrin in weaning piglets basal diet on nutrient digestibility, biochemical indicators of nutrition in serum, enzymes activ- ity in serum. Ninety-six weaning piglets at 21-day-old were randomly allocated to 4 treatments with 4 rep- licates of 6 piglets per replicate. Each treatment was fed basal diet supplemented with 0,250,500 and 750 mg/kg laetoferrin respectively. The experimental period was 21 days. The results showed： basal diets sup- plied with lactoferrin had t...
