| 摘 要： | 采用单因子试验设计,将20只成年藏獒犬(♂,2岁)随机分为5组,每组4只,饲喂不同蛋白质水平的饲粮,利用氮平衡试验,研究了成年藏獒犬对多种蛋白原料配合而成的不同蛋白质水平的目粮中蛋白质和可消化蛋白质的需要量.结果表明:食入氮对存留氮的回归关系为y1=1.305x1+2.549,可消化氮对存留氮的回归关系为y2=0.97...

| Abstract: | A single factorial arrangement of treatments and self-control design was adopted to investigate the protein and the digestible protein requirement with different pretein source diet by nitrogen balance test.20 adult Tibetan mastiffs(2 ages,♂)were chosen in the test.The results showed that the regression equation between nitrogen consumed and nitrogen retained was y1=1.305x1+2.549.The regression equation between nitrogen digested and nitrogen retained was y2=0.977x2+2.306.When x1=0,y1=2.549,that meant one mastiff required 15.931 g protein each day(2.549 g nitrogen each day).When x2=0,y2=2.306,that meant one mastiff require 14.413 g protein each day(2.306 g nitrogen each day). |
