摘　　要：目的本试验旨在研究不同蛋白水平对实验藏酋猴生长性能和血液生化指标的影响并确定幼年实验藏酋猴的蛋白营养需要量。方法选用15只幼年实验藏酋猴随机分为5个处理组,每个处理3个重复,分别饲喂蛋白水平为11.1%、16.1%、20.5%、24.5%和29.8%的日粮,试验期90 d。结果随着日粮中蛋白水平的提高,实验藏酋猴的增重、血清白蛋白、球蛋白、天门冬氨酸氨基转移酶、丙氨酸氨基转移酶和尿素氮含量显著增加(P<0.05),而血清总蛋白、甘油三酯、γ-谷氨酰胺转移酶和碱性磷酸酶无显著差异。应用折线法确定幼年实验藏酋猴的蛋白营养需要量为23.69%。结论日粮蛋白水平对实验藏酋猴生长性能有显著影响,从生物学和经济学角度考虑,初步认为在本试验条件下,未成年实验藏酋猴日粮蛋白水平以23.69%最合适。Objective To investigate the effect of protein on growth and serum biochemical indexes of juvenile Tibetan macaqueb by a ninety-day feeding trial. Method Diets with five levels of protein （ 11.1% , 16. 1% , 20.5% , 24.5% and 29.8% ） were fed to Tibetan macaque. The results showed that： weight gain, serum albumin, globulin increased with the increasing protein levels （P 〈 0. 05）. Resnlts Activities of serum aspartate aminortransferase, alanine aminotransferase and urea nitrogen were significantly improved in response to the increasing levels of dietary protein. But there was no significant difference in serum total protein, triglycerides, Gamma-irradiation glutamine shift enzyme and alkaline phosphates among these groups. The dietary protein requirement for weight gain of juvenile Tibetan macaque pestimated by brokenline model was 23.69%. Conclusim Under the cage conditions the 23.69% protein is the best choice considering animal biology and feed expense.
