摘要
以宁夏晓明农牧股份有限公司海兰褐父母代育成鸡为试验对象,研究了夏季不同饲养方式对鸡舍有害气体及微生物菌群数的影响.结果表明:在鸡架上1.75m处,3种饲养方式下鸡舍中的NH3、H2S以及微生物菌群数差异均不显著(P>0.05),鸡架上1.15、0.35m处高床平养鸡舍的NH3、H2S体积比以及微生物菌群数均显著低于普通平养和笼养(P<0.05).说明夏季高床平养有利于降低鸡舍有害气体及微生物菌群数,能够提高鸡舍的环境质量.
To selection Hay-Line Brown parents kind of chickens as test objects,we study on the effects of different feeding mode to the harmful gas and Microbial number.Results indicate that： in the chicken frame of 1.75 m eters,three kinds of feeding mode henhouse of NH3 and H2S concentration and microbial number differences are not significant（P 0.05）,Chicken on 1.15、0.35 m eters high bed flat a have henhouse of NH3 and H2S concentration and microbial number were significantly lower than ordinary flat to raise and cage culture（P 0.05）.We conclude that summer high bed flat keep reducing the henhouse harmful gas and microbial flora number,and it can improve the quality of the henhouse environment.
