摘要:

本试验旨在研究沙棘叶黄酮对阿勒泰羊生长性能、屠宰性能和血清生化指标的影响。采用单因素随机区组试验设计,选择60只6月龄平均体重约为(28±3)kg的健康阿勒泰羊,随机分成4组,低剂量沙棘叶黄酮组、中剂量沙棘叶黄酮组、高剂量沙棘叶黄酮组和对照组(即SJHT-1组、SJHT-2组、SJHT-3组和Con组),每组3个重复,每个重复5只。对照组饲喂基础日粮,试验组分别添加(0%、0.10%、0.25%、0.50%)的沙棘叶黄酮。试验期64 d。结果表明:1)与Con组相比,SJHT-3和SJHT-2组显著提高平均日增重(P<0.05)。2)各组间屠宰率差异不显著(P>0.05);与Con组相比,SJHT-3组极显著提高净肉率(P<0.01);SJHT-3组极显著降低脂肪率(P<0.01),SJHT-2组显著降低(P<0.05); SJHT-3组显著降低腹脂率(P<0.05)。3)与Con组相比,SJHT-1组极显著提高血清中总蛋白含量(P<0.01);SJHT-2显著提高总蛋白含量(P<0.05);SJHT-3极显著降低尿素氮含量(P<0.01);SJHT-1组极显著提高低密度脂蛋白胆固醇(P<0.01),SJHT-2组显著提高低密度脂蛋白胆固醇(P<0.05);SJHT-3组显著提高碱性磷酸酶含量(P<0.05);SJHT-2组显著提高乳酸脱氢酶含量,比Con组提高28.04%;SJHT-1组极显著提高总钙含量(P<0.01),比Con组提高10.64%。谷丙转氨酶、谷草转氨酶、谷氨酰胺转氨酶和磷酸肌酸激酶各组间均差异不显著(P>0.05)。由此得出,在阿勒泰羊日粮中添加不同剂量的沙棘叶黄酮,可以提高阿勒泰羊的日增重,提高饲料效率;提高净肉率,降低胴体脂肪率和腹脂率。沙棘叶黄酮使阿勒泰羊血清总蛋白升高和尿素氮含量、碱性磷酸酶含量降低,表明沙棘叶黄酮可以提高阿勒泰羊蛋白质的合成,提高钙代谢,而且对其他生理指标无不良影响。

Abstract:

This experiment was conducted to investigate the effect of flavonoids of sea buckthorn leaves on growth performance,slaughter performance and serum biochemical indexes of Altay sheep.A total of 60 6-month-old with average weight of (28±3)kg,health Altay sheep were randomly divided into 4 groups:low doses of flavonoids of Sea buckthorn leaves group,middle dose of flavonoids of Sea buckthorn leaves group,high dose of flavonoids of Sea buckthorn leaves group and the control group (SJHT-1 group,SJHT-2 group,SJHT-3 group and Con group ),with 3 replicates per group and 5 sheep per replicate.The control group(Con) was fed the basal diet,the test groups were fed with different doses of flavonoids of sea buckthorn leaves(0%,0.10%,0.25% and 0.50%).The experiment lasted for 64 days.The results showed as follow:1) Compared with the Con group,the average daily gain in SJHT-3 and SJHT-2 groups were significantly increased (P<0.05).2) Slaughter rates among all groups were not significantly different (P>0.05); Compared with the Con group,the Net meat rate in SJHT-3 group significantly increased (P<0.01); Fat rate in SJHT-3 group significantly reduced (P<0.01),SJHT-2 significantly lower (P<0.05); Percentage of abdominal fat in SJHT-3 group significantly reduced (P<0.05).3) Compared with the Con group,TP in SJHT-1 group significantly increased (P<0.01),SJHT-2 significantly increased (P<0.05); UN in SJHT-3 group significantly reduced (P<0.01); LDL-C in SJHT-1 group significantly increased (P<0.01),SJHT-2 group improved significantly (P<0.05); ALP in SJHT-3 group significantly increased (P<0.05); LDH in SJHT-2 group significantly increased (P<0.05); Ca in SJHT-1 group significantly increased (P<0.01).ALT,AST,GGT and CK of the trial group were not significantly different (P>0.05) among all groups.It follows that,adding different doses of flavonoids of sea buckthorn leaves in diets of Altay sheep,can improve daily gain and lower feed efficiency and improve Net meat rate and reduce fat rate and percentage of abdominal fat.Flavonoids of sea buckthorn leaves can elevate serum TP and UN of Altay sheep,and decrease ALP,indicating that flavonoids of sea buckthorn leaves can increase protein synthesis of Altay sheep,but also conducive to the amino acid balance,improve the metabolism of calcium,and have no adverse effect on other physiological indexes.
