摘要

本试验旨在研究不同氮源对泌乳山羊生产性能的影响,以及对微生物嘌呤衍生物和血液代谢产物排泄的影响。选用32只泌乳山羊(体重38.85±2.14 kg,日产奶量1979±0.25 g),采用完全随机的单因素方差分析设计。试验期为10周:1)对照(以油菜粕为氮源);2)尿素(0.5%尿素);3) Optigen (0.55% Optigen- Alltech)4)基于干物质摄入量的聚合物涂层尿素(PCU-国际专利号:A01K5/00, 0.7% PCU)。非蛋白氮组对乳成分、微生物蛋白合成及尿素、胆固醇、谷丙转氨酶等血液因子的影响均显著高于对照组(p > 0.05), PCU、Optigen、urea组的干物质采食量显著低于对照组(p > 0.05)。PCU山羊微生物蛋白合成量为22.5 g d -1,显著高于其他处理(p < 0.05)。PCU和Optigen山羊血浆胆固醇升高,而尿素和对照山羊血浆尿素浓度升高。PCU组产奶量高于尿素组和对照组。与其他处理相比,PCU和Optigen山羊的饲料系数显著提高(p < 0.05)。本研究表明,聚合物包膜尿素可以作为氮源,提高山羊产奶性能。

Dietary polymer-coated urea enhances the goats lactational performance, excretion of microbial purine derivatives and blood metabolites in the semi-arid zone of Iran
This study aimed to determine the effect of using different sources of nitrogen to supply part of degradable intake protein needs in lactating goat performance and its effect on excretion of microbial purine derivatives and blood metabolites. Thirty-two lactating Saanen goats (body weight 38.85 ± 2.14 kg and 1979 ± 0.25 g day-1 milk yield) were used in a one-way ANOVA completely randomized design. Goats were assigned to the following treatments for a 10-wk experimental period: 1) Control (canola meal as a nitrogen source); 2) Urea (0.5% urea); 3) Optigen (0.55% Optigen- Alltech. Inc., Lexington, KY) and 4) Polymer-Coated Urea (PCU- international patent number: A01K5/00, 0.7% PCU) based on dry mater intake. Non-protein nitrogen groups had a comparative effect (p > 0.05) between control and other treatments on milk composition, microbial protein synthesis and they affected on blood factors including urea, cholesterol, and ALT. Dry matter intake decreased (p > 0.05) in PCU, Optigen, Urea than Control goats. Synthesis of microbial protein in PCU goats was 22.5 g day-1 and it was greater (p > 0.05) than other treatments. Plasma cholesterol was increased in PCU and Optigen, whereas urea concentration was increased in Urea and Control goats. Milk production was higher in PCU than Urea and Control. Feed conversion ratio was improved (p > 0.05) in PCU and Optigen goats versus other treatments. This study demonstrated that polymer-coated urea can be utilized as a nitrogen source and improve goats milk performance.
