摘要

This study was to quantify the milk protein and amino acids (AA) in response to rumen-protected lysine (Lys) and methionine (Met) supplementation in dairy cows fed distillers dried grains with solubles (DDGS) diet. Forty cows were divided into five dietary treatments: soybean meal diet (SM), DDGS diet and DDGS diets with 40 g/day Lys (DL), 20 g/ day Met dry matter (DM) and 20 g/ day Met plus 40 g/ day Lys (DLM), separately. Compared with SM, DL and DM groups, DLM group increased milk yield, 4% fat-corrected milk, energy-corrected milk yield and protein in milk. DDGS treatments increased total AA and the essential AA in milk. Results indicated that dietary DDGS increased intestinal supplies of Lys and Met.

此研究的目的是量化的乳蛋白质和氨基酸（AA）响应于瘤胃 - 被保护赖氨酸（Lys）和甲硫氨酸（Met）补充奶牛饲喂干酒糟及其可溶物（DDGS）的饮食。四头牛被分为五个饮食治疗：豆粕日粮（SM），DDGS饲料和DDGS饲料40克/天赖氨酸（DL），20克/天见了干物质（DM）和20克/天会见加40克/日赖氨酸（DLM），分别。与SM，DL和DM组相比，DLM组增加产奶量，4％脂肪校正奶，能源校正奶产量和蛋白质含量的牛奶。 DDGS治疗增加总AA和牛奶中的必需氨基酸。结果表明，日粮DDGS增加赖氨酸和蛋氨酸肠道用品。
