【摘要】 本试验目的在于研究光合细菌TR饲料饲喂蛋鸡的效果。试验选用435日龄蛋鸡192只,随机均分为4组,设一个对照组,3个试验组。试验1、2、3组分别按2％、4％、6％光合细菌TR饲料等比例替代基础日粮,对照组用基础日粮,试验期30天,统计各组的产蛋数、蛋重、耗料等情况。试验结果表明,试验各组产蛋量均比对照组提高,试验2组提高明显,与对照组差异极显著(P<0.01)。试验各组蛋重有一定的提高,而且饲料消耗均低于对照组,按料蛋比计算,试验1、3组与对照组差异不显著(P>0.05),试验2组与对照组差异显著(P<O.05)。所以,利用光合细菌TR饲料在蛋鸡生产中替代一定比例全价配合饲料,可显著提高产蛋量和饲料报酬,有较好的经济效益。更多还原

【Abstract】 The aim of this experiment is to observe the effects of photosynthesized bacteria forage on egg - chickens. 192 435 - day - old chickens were divided into 4 groups,in which Group 1,2,3 were fed with 2%,4%,6% of TR photosynthesized forage in place of basic feed, Group 4 as the controlled one. After 30 days, the egg production, egg weight and feed consumed of each group were noted down. The experimental results indicated that follows: the egg production of each experimental group increased: among the experimental group,Group 2 was remarkable different with the controlled group(P < 0.01); the egg weight of each experimental group increased a little with less consumption of forage. Based on the feed conversion ratio(FCR) ,Groupl and Group3 were slightly different(P> 0.05) ,Group2 was much different from the controlled (P < 0. 05). Therefore, remarkable increasing of egg production and the reward of forage could be achieved by using TR photosynthesized bacteria forage in place of common forage.更多还原
