调整营养制度降低肉仔鸡饲养成本的研究

设计３个试验研究了调整营养制度，降低肉仔鸡饲养成本的措施。试验结果表明，让肉仔鸡从３周龄提前到２周龄时由生长前期料换用生长中期料，不影响其３７日龄体重及０～３７日龄的饲料利用。在无严重应激存在的情况下，肉仔鸡上市（４９日龄）前３周内的基础日粮中不补加微量元素和２周内不补加维生素不影响生长和饲料转化率。以上对肉仔鸡生长前、后期营养摄入量的调整均可有效降低饲养成本

Modification of the Nutritional Regime to Reduce the Feeding Cost of Broilers

Three experiments were conducted to study the approaches to reduce the feeding cost of broilers through modifying the nutritional regime. The results showed that in a broiler feeding program,the switch from starter to grower diet at two weeks instead of three weeks of age,did not influence the live body weight at age of 37 days and the feed conversion efficiency during the period of 37 days,and as long as no obvious stressors exist.supplemental microminerals and vitamins in the finisher diet can be withdrawn without sacrifice in performance,three weeks and two weeks respectively before the market weight reached. The feeding cost of broilers can be reduced through modifying the amounts of nutrients intake of starters and finishers as shown above.
