【摘要】 将7周龄中雏分为试验组(豌豆蛋白粉组)与对照组(国产鱼粉组),在规模生产条件下进行为期14周的饲喂试验(7—20周龄),定期检测其增重、耗料和死淘率等指标,观察豌豆蛋白粉替代鱼粉在育成期的饲养效果。两个鸡场7850只鸡的试验结果,试验组生产成绩均优于对照组。平均体重20周末分别比对照组高52克和66.67克(P<0.01),差异极显著。死淘率分别降低0.15％和0.26％。每百千克饲料成本分别降低6.83元和9.45元。育成期每只鸡降低饲料成本平均1.32元,经济效益显著。更多还原

【Abstract】 The 7-week old growing were randomly divided into testing group(feeding proteinpowder of pea)and control group (feeding native fish meal). The feeding test was con-ducted 14 weeks (from 7 week to 20 week old) in two different chicken farms. Gainweight,feed consumption, death-culling rate were recorded. The results in two chickenfarms showed that the performance of test group was better. The average weight at 20week of age of test group was in creased 52g and 66. 67g than that of control group,re-spectively. The difference was very significant (P>0. 01). Death-culling rate of testgroup reduced 2. 06 Per cent and 3. 24 Per cent,respectively. But the difference was notsignificant (P>0. 05)The average feed consumption reduced 0. 15% and 0. 26% respec-tively. the cost of per 100kg feed in test group reduced 6. 83 yuan and 9. 45 yuan. The costof per-growing feed reduced 1. 32 yuan.更多还原
