牛羊高效复合蛋白特种饲料对奶畜生产性能的影响

系列饲养试验表明，蛋白质饲料不足时，给奶畜添喂牛羊高效复合蛋白特种饲料（科威４１８），产奶量提高２９．３％（Ｐ＜０．０５），鲜奶品质显著改善，蛋白质饲料相对饲料相对充足时，用科威４１８代精料中２５－１００％的豆饼或豆子，产奶量提高７．９％（Ｐ＜０．０１），饲料转化率提高２５．８６％（Ｐ＜０．０５），鲜奶中常规养分氨基酸含量增加，以上两种情况时每牛每天分别可增收４．５６元和２．１８元；每羊每天科威４

EFFECTS OF THE SPECIAL COMPOUND FEED WITH HIGH PROTEIN CONTENT ON THE PERFORMANCE OF DAIRY ANIMALS

When the special compound feed (named Kewei-418) was added to the diet of dairy animals under the situation of protein feed shortage, the milk yield was increased 29. 3%(P<0. 05) and the quality of fresh milk was greatly improved. When 25% to 100% soybean meal or soybean in the concentrates was replaced by Kewei -418 under the situation of protein feed wealthy, the milk production and feed coversion efficiency,increased 7. 9% (P<0. 01) and 25' 86% (Prt0. 05), respectively, and the contents of routine nutrients and amino acids in the fresh milk increased(P<0. 05), also. The daily net income of each milking cow could be increased 4. 56 and 2. 18 Yuan(RMB) at the two conditions, respectively. Tbe maximum daily intake of Kewei - 418 was 151. 3 grams for dairy goats, that is the 5. 0 to 7. 5 times of its routine feeding level.
