摘要
在相同的饲养管理条件下,将56只29日龄、健康贵妃鸡分成4组,每组14只,空白对照组、饲喂1‰、2‰、4‰EM原露的试验组分别标号为A、B、C、D四组,进行为期28d(5 ̄8周龄)的饮水试验。每日记录其饲料消耗量,并在每周龄末称重。试验末期进行屠宰试验。结果表明:①试验期A、B、C、D四个组的平均日增重量分别为9.28g、10.04g、10.47g、10.32g,期末料重比分别是:A组为3.11、B组为2.98、C组为2.90、D组为2.97,以C组的饲料报酬最高;②无论是用1‰、2‰还是4‰比例的EM原露饲喂贵妃鸡,都能促进日增重、提高饲料转化率;③EM原露对贵妃鸡的屠宰性能影响不明显。总体情况比较,选用2‰浓度EM原露的C组饲喂效果要优于其它三组。
Under the same management conditions,56 of 29-day-old healthy Princess Chicken were divided into four groups for a drinking water test of 28 days (5-8 weeks).One group was blank while the remaining three groups were adding 1‰,2‰,4‰ and labeled the blank of EM (groups as A,B,C,D respectively).Recorded feed consumption daily and weighed the chickens weekly,a slaughter experiment at the end of the trial.The results showed:During the trial, the average daily weight increase of the groups was 9.28g,10.04g,10.47g,10.32g.The cumulative feed and weight gain ratio of the groups was 3.11,2.98, 2.90,2.97.This test had shown that it was able to promote the daily weight of princess chickens and feed conversion by adding 1‰,2‰,4‰ of EM in the feed.,In addition,the slaughter experiments showed:EM had little impact on the performance of slaughter.Overall,the performance of the group that adding 2‰ of EM was better than the other three groups.
