饲粮乳清粉含量对乳猪培育性能的影响

Effect of Dried Whey in Creep Fed Ration on the performance of Suckling Piglets

以含乳清粉5、10、15％的乳猪料以及不含乳清粉的酸化乳猪料和合资企业生产5311乳猪料饲喂1～5周龄的杜浙杂交仔猪32窝。仔猪5周龄断奶平均体重分别为8.20±0.19、7.09±0.21、7.81±0.16、7.87±0.18和7.71±0.23公斤(P<0.01);其平均日增重相应为192.0±5.0、162.2±5.3、182.8±4.4、181.0±4.9和178.7±6.3克(P<0.05);饲料/增重分别为0.19、0.30、0.20、0.26和0.26;7～35日龄仔猪成活率分别为98.6、98.3、98.6、98.3和100％;每公斤增重的乳猪料成本为0.30、0.53、0.40、0.41和0.45元。从上述指标分析,以含5％乳清粉的饲粮组较好。

330 crossbred suckling piglets were fed on five diets from 1-week to s-weeks of age. Diet 1 added 2 % citric acid and no dried whey; Diet 2 - 4 contained 5, 10 and 15% dried whey, respectively, and Diet 5 was a commercial complete diet (commercial name 5311 complete diet for suckling pig).The results indicated that the piglets fed diet containing 5 %dried whey exhibited heavier average weaning body weight at 5 -weeks of age. faster gain rate, more superior efficiency of feed utilization and higher profit than others. However, feed intake and survival rate was similar among different dietary treatment groups.
