【摘要】 研究了代乳粉对早期断奶羔羊生长发育及健康状况的影响,结果表明:(1)美利奴羊饲喂代乳粉对早期断奶的羔羊与对照组羔羊日增质量差异不显著(P>0.05),波尔山羊饲喂代乳粉对早期断奶的羔羊日增质量显著高于对照组羔羊(P<0.05),试验组为180.7g,对照为158.0g。(2)各日龄阶段美利奴羊、波尔山羊试验组和对照组羔羊胸围差异均不显著(P>0.05)。整个试验期美利奴羊试验组和对照组羔羊的胸围差异不显著(P>0.05),波尔山羊试验组和对照组羔羊的胸围差异显著(P<0.05),分别增加15.7cm和12.2cm。(3)各日龄阶段美利奴羊、波尔山羊试验组和对照组羔羊体高差异均不显著(P>0.05)。整个试验期美利奴羊试验组和对照组羔羊的体高增加差异不显著(P>0.05);波尔山羊试验组和对照组羔羊的体高增加差异不显著(P>0.05)。(4)早期断奶羔羊饲喂代乳粉,试验组羔羊成活率达到96.3%,对照组为87.5%,试验组较对照组提高8.8个百分点。代乳粉饲喂早期断奶羔羊有利于羔羊生长发育,提高羔羊抗病力,增强体质,降低羔羊的发病率。更多还原

【Abstract】 The effects of babymeal on the growth performance and health status in early-weaned lamb were studied. The results showed that:(1)There was no significant difference (P>0.05)for Merino sheep between control group and experimental group after being fed babymeal in early-weaned lamb. There was significant difference (P<0.05)for Boer goat between control group (158.0 g) and experimental group (180.7 g ) after being fed babymeal in early-weaned lamb. (2)Chest measurements were no significant differences (P>0.05)for each day-old stage lambs between control group and experimental group including Merino sheep and boer goat. During the whole experiment period, there was no difference(P>0.05)for chest measurement between control group and experimental group in Merino sheep. To the contrary, lamb’s chest measurement in experimental group (15.7 cm)was significantly lager (P<0.05)than that of control group (12.2 cm)for boer goat. (3)Body depth were no significant differences (P>0.05)for each day-old stage lambs between control group and experimental group including Merino sheep and boer goat. There were no significant differences (P>0.05)for body depth between control group and experimental group including Merino sheep and Boer goat during the whole experimental period.(4) After lamb was fed babymeal, survival rates were 96.3% and 87.5% in experimental group and control group, respectively. The lamb survival rate in experimental group increased 8.8% than control group. The results showed that early weaned lambs fed babymeal was conducive to growth and development , and could improve lamb disease resistance, enhance physical fitness, reduce the incidence of lamb.更多还原
