接种有益菌的糟渣饲料对蛋鸡生产性能的影响

The effect of residual forage inoculated prebiotics on performance of laying hens

对接种有益菌的糟渣饲料对产蛋性能的影响进行了研究 ,结果表明 :日粮中使用接种有益菌的糟渣饲料的产蛋率、总蛋重、饲料转化率比Ⅰ组和Ⅱ组分别高 3 .80 %和 6 .50 % ;3 .0 %和 6 .86 % ;3 .0 1 %和 6 .85 % ;破蛋率和死淘率分别降低 1 5 .7%和 1 7.5 % ;1 4 .2 %和 33 .2 % ;对蛋壳品质没有影响。使用接种有益菌的糟渣饲料可降低饲料成本 。

Beijing White-939 laying hens of 280 day-old were ass igned randomly into 3 groups to study the effect of residual forage inoculated prebiotics on g rowth performance of laying hens. The diets were formulated to contain 3% residu al forage inoculated prebiotics (experimental groups); 1% fish meal and 1% corn as well as 1% wheat bran, respectively (control Ⅰgroup); 3% untreated residual forage (control Ⅱ group).The main results showed as follows: The experime ntal groups had a increased egg rate,gross egg weight and forage ratio of 3.80% and 6.50%; 3.0% and 6.86%; 3.01% and 6.85% compared with control Ⅰand control Ⅱ groups; a decreased broken egg rate,mortality and cull rate of 15.7% and 17. 5%; 14.2% and 33.2%; but has no significant difference of the quality of egg-she ll. It could also decrease the feed cost, thus increase the ecnomic efficience.
