颗粒化全混合日粮对舍饲羔羊生产性能的影响

Granular Total Mixed Rations on the Performance of Confined Lambs

将24只断奶羔羊随机分为2组,对照组饲喂羔羊精料和苜蓿干草,试验组饲喂颗粒(膨化)全混合日粮,试验期为30 d,研究颗粒(膨化)全混合日粮对舍饲羔羊生产性能的影响。试验结果表明,饲喂颗粒(膨化)全混合日粮,舍饲羔羊的平均日增质量提高31.22%,饲料转化率提高17.25%,尤其在断奶初期,可有效减缓羔羊的断奶应激症状和降低羔羊腹泻率,对培育壮羔、提高育成羊的等级、发挥其优良性能具有重要作用。

This research investigated the influence of granular （extruding） total mixed ration on the confined lamb performance. 24 weaned lambs were assigned to 2 groups, which were control group feeding with concentrate and dry alfalfa, and treatment group feeding with total mixed ration. Experiment lasted for 30 days. Results showed that the average daily gain of confined lambs in treatment group increased by 31.22%, and its feed conversion rate increased by 17.25%. The lamb weaning stress symptoms and the rate of diarrhea reduced by feeding granular total mixed ration, especially at the early weaning period. It was concluded that granular mixed ration improved the level of breeding sheep, showed excellent lamb performance and played an important role on cultivate strong lamb.
