花椒籽对湖羊羔羊生产性能、内脏器官指数和瘤胃组织形态发育的影响
Effects of Zanthoxylum bungeanum seeds on production performance,internal organ index and rumen tissue morphology of Hu sheep lambs
目的 研究饲粮中添加花椒籽对湖羊羔羊生产性能、屠宰性能、内脏器官指数和瘤胃组织形态的影响。 方法 选取3月龄体质量(25.66±3.03)kg相近的健康湖羊公羔27只,随机分为3组,分别在基础饲粮中添加0%(对照组)、3%(试验I组)、6%(试验II组)的花椒籽,预试期10 d,正试期90 d。 结果 对照组料重比显著高于试验I组和试验II组(P<0.05);各组之间屠宰性能差异不显著,但试验I组和试验II组背膘厚有显著高于对照组的趋势(P=0.073);试验I组瘤胃重量显著高于对照组(P<0.05),试验I组瘤胃相对重量、瓣胃重量和瓣胃相对重量显著高于对照组和试验II组(P<0.05),试验I组皱胃重量显著高于试验II组(P<0.05),试验I组总胃重和总胃重相对重量显著高于对照组和试验II组(P<0.05);试验II组瘤胃乳头高度显著高于试验I组和对照组(P<0.05),试验I组瘤胃乳头高度显著高于对照组(P<0.05);对照组和试验I组瘤胃乳头宽度显著高于试验II组(P<0.05);试验I组和试验II组角化层厚度显著高于对照组(P<0.05)。 结论 饲粮中添加3%和6%的花椒籽可促进湖羊羔羊瘤胃组织发育,降低料重比,其中添加3%的花椒籽更有利于复胃的生长。
Objective This experiment was conducted to investigate the effects of dietary Zanthoxylum bungeanum seeds on growth performance,slaughter performance,organ index and rumen tissue morphology of Hu lambs. Method Twenty-seven healthy male lambs of similar body weight (25.66±3.03)kg at 3 months of age were randomly divided into 3 groups,the basal diets were supplemented with 0% (control group),3% (experimental group I) and 6% (experimental group II) Z.bungeanum seeds,respectively.The pre-trial period was 10 days and the formal trial period was 90 days. Result The feed to gain ratio of the control group was significantly higher than that of test groups I and II (P<0.05).There was no significant difference in carcass performance (P>0.05),but the backfat thickness of experimental groups I and II was significantly higher than that of the control group (P=0.073).The rumen weight of test group I was significantly higher than that of the control group (P<0.05),the relative rumen weight,omasum weight and relative omasum weight of test group I were significantly higher than those of the control group and test group II (P<0.05),and the abomasum weight of test group I was significantly higher than that of test group II (P<0.05).The total stomach weight and the relative weight of the total stomach weight of test group I were significantly higher than those of control group and test group II (P<0.05).The ruminal papilla height of test group II was significantly higher than that of test group I and control group (P<0.05),and that of test group I was significantly higher than that of control group (P<0.05).The ruminal papilla width of the control group and test group I was significantly higher than that of test group II (P<0.05).Stratum corneum thickness of test groups I and II was significantly higher than that of control group (P<0.05). Conclusion Diets supplemented with 3% and 6% Z.bungeanum seeds can promote rumen tissue development and reduce the feed to gain ratio of Hu lambs,but the addition of 3% seeds is more conducive to the growth of stomachus compositus.
