摘  要:
采用单因子试验设计,将12只成年贵宾犬(♂,2岁)随机分为3组(每组4只),喂以不同蛋白质水平(1.15 NRC1、.25 NRC1、.35 NRC)的全价饲粮,利用氮平衡试验研究了成年贵宾犬对多种蛋白原料配合日粮中蛋白质的需要量.结果表明:食入氮与存留氮之间的回归关系为:y1=10.76+1.73x1(P=0.15),可消化氮与存留氮的回归关系为:y2=6.35+1.63x2(P=0.04).当x1=0时,y1=10.76,即成年贵宾犬每天总氮最低需要量为10.76g.只-1,蛋白质最低需要量为67.28 g.只-1.当x2=0时,y2=6.35,即成年贵宾犬每天最低可消化氮需要量为6.35 g.只-1,最低可消化蛋白质需要量为39.66 g.只-1.

摘  要:
The experiment was conducted by using 12 adult Poodle dogs(2 ages,♂) to investigate the requirement of protein with different levels and sources in protein(1.15×NRC,1.25×NRC,1.35×NRC) by nitrogen balance test.A single factorial arrangement of treatments and self-control design was adopted in the experiment.The results showed that the regression equation between nitrogen intakes and nitrogen retained is y1=10.76+1.73x1(P=0.15),and the regression equation between nitrogen digested and nitrogen retained is y2=6.35+1.63x2(P=0.04).The results indiacted that the adult Poodle dogs require 67.28 g·只-1 protein(10.76 g·只-1 nitrogen)or require 39.66 g·只-1 digestible protein(6.35 g·只-1 digestible nitrogen).
