摘要
采用3×3双因子试验设计,其中粗蛋白质设17.0%、18.5%、20.0%三个水平,大米活性肽设0、1%、2%三个水平,研究了日粮中粗蛋白质水平和大米活性肽的不同添加量对断奶仔猪生长性能和血液生化指标的影响。结果表明,在断奶仔猪的日粮中添加1%~2%的大米活性肽,可明显提高仔猪的生长性能,平均日增重和平均日采食量分别增加5.37%~7.13%和4.62%~5.49%,料重比降低了0.63%~1.86%;还可将日粮中粗蛋白质含量降低1.5~3.0个百分点;同时,添加1%~2%的大米活性肽还能显著增强仔猪的抗氧化能力和免疫功能。
This experim entw as conducted to study effects ofdietary crude protein (CP) and rice active peptide levels on grow th perform ance and blood biochem icalindices in weaned piglets.Two hundred and sixteen 28-day-old weaned D×L×Y pigs were used in a 3×3 double factorialdesign trialand randomly allocated to 9 groups with 4 replicates of 6 piglets each.The piglets were fed atthe dietary 17.0% ,18.5% or 20.0% CP and 0,1% or 2% rice active peptide levels,respectively,w hich lasted for 21 d.The results show thatthe dietary CP levelhad no significanteffecton grow th perform ance and blood biochem icalindices(P >0.05).The dietary rice active peptide levelhad significantor very significanteffecton ADG ,ADFI,SOD ,GSH -Px,IgA ,IgG and IgM (P<0.05 or P <0.01).Itw as concluded thatthe dietsupplem ented atthe 1% ~2% rice active peptide level could reduce the dietary CP level by 1.5~3 percentage points, and could im prove the piglets’ grow th perform ance,body oxidation resistance and immunity function.
