【摘要】：本试验旨在研究1~41日龄哺乳山羊羔羊灌服N-氨甲酰谷氨酸(NCG)对其生长性能、血液参数及器官重的影响。选取1日龄体重[(3.1±0.3)kg]相近的哺乳山羊羔羊32只,随机分在2个组中(每组16只),按每天分别灌服0(对照)、100 mg/kg BW的NCG。于羔羊41日龄时进行屠宰。结果表明,与对照组相比:1)灌服NCG显著提高了1~41日龄羔羊平均日增重,显著降低了腹泻率(P0.05);2)灌服NCG显著提高了41日龄羔羊血浆中总蛋白和白蛋白含量(P0.05),而显著降低了21和41日龄羔羊血浆氨和尿素氮含量(P0.05);3)灌服NCG显著提高了21和41日龄羔羊血浆胰岛素、生长激素及一氧化氮含量(P0.05);4)灌服NCG显著提高了41日龄羔羊血浆精氨酸、鸟氨酸和瓜氨酸含量(P0.05)。5)灌服NCG显著提高了羔羊脾脏、小肠及大肠相对重量(P0.05)。结果提示,灌服NCG促进哺乳山羊羔羊的生长发育及内源精氨酸合成。
[Abstract]:The aim of this study was to study the effects of N- amoyl glutamic acid (NCG) on the growth performance, blood parameters and organ weight of 1~41 day old lactation goat lambs. A total of 1 days old weight (3.1 + 0.3) kg] of 32 lambs of lactating goats were randomly divided into 2 groups (16 in each group), and 0 (control) and 100 mg/kg BW NCG were administered daily. The lambs were slaughtered at the age of 41 days. The results show that, compared with the control group: 1) fed with NCG significantly increased the average daily gain of lamb at the age of 1~41 days, significantly reduced the rate of diarrhea (P0.05); 2) oral administration of NCG significantly increased the total protein and albumin content of 41 day old lamb in plasma (P0.05), and significantly decreased by 21 and ammonia and 41 day old lamb plasma urea nitrogen content (P0.05); 3) fed with NCG significantly increased 21 and 41 day old lamb plasma insulin, growth hormone and nitric oxide (P0.05); 4) fed with NCG significantly increased the 41 day old lamb plasma arginine, ornithine and citrulline content (P0.05). 5) the relative weight of the spleen, small intestine and large intestine (P0.05) of the lamb was significantly increased by NCG. The results suggest that NCG irrigation can promote the growth and development of lactation goat lambs and the synthesis of endogenous arginine.

【正文快照】： 精氨酸作为维持幼年家畜最佳生长和氮平衡的必需氨基酸[1],在促进幼畜肠道蛋白质合成,提高肠道免疫力、抗氧化能力及维护肠道健康等方面都具有重要作用[2]。由于母乳中所含的精氨酸量和自身合成的量往往无法满足幼年家畜的营养需求,可能会限制其生长性能的发挥,因此需要额外提
