本文对广东地区生产的几种含乳固体饮料进行了分析与动物实验。每组取雄性断乳大鼠10只(组3为8只),以米和6％黄豆粉为基本饲料。正对照组为基本饲料添加12％的全脂奶粉;负对照组只进食基本饲料。四个实验组分别是基本饲料添加35％北芪麦乳精(组3)、35％的椰奶麦乳(组4)、35％椰奶酪(组5)与35％的麦芽蛋白粉(组6)。除组6外,各组饲料蛋白质水平在8.2～8.9％之间。随意进食,单笼饲养四周。通过大鼠的生长效应、食物效价(FE)、每克食物蛋白质增加体重的克数、血红蛋白、血清白蛋白、肝氮含量与肝重等实验指标比较。结果表明:正对照组大鼠四周净增重142.3g,负对照组98.2g,组3～组6分别为81.2g、90.1g、79.9g和55.7g。正对照组与各实验组差异极显著(P<0.001)。饲料消耗、食物效价、每克食物蛋白质增加体重的克数表明,正、负对照组亦比四个实验组高。血清白蛋白正对照组平均值是3.4g/dl,四个实验组是2.5～2.7g/dl(P<0.001)。血红蛋白与肝氮含量在各组未发现显著性差异。肝重随体重而变化,正对照组也明显高于其他各组。
In this paper, several milk solid beverages produced in Guangdong area were analyzed and animal experiments were conducted. Ten male weanling rats (eight in Group 3) were used in each group and rice and 6% soybean powder were used as the basic feed. The positive control group added 12% whole milk powder to the basic feed; the negative control group only consumed the basic feed. The four experimental groups consisted of basic feed supplemented with 35% North buckwheat milk extract (Group 3), 35% coconut milk yoghurt (Group 4), 35% coconut milk (Group 5) and 35% malt protein powder (Group 6). With the exception of group 6, feed protein levels in each group ranged from 8.2 to 8.9%. Free to eat, single cage for four weeks. The rat’s growth effects, food titers (FE), grams of body weight per gram of protein, and hemoglobin, serum albumin, liver nitrogen, and liver weight were compared. The results showed that the rats in the positive control group had a net weight gain of 142.3g, a negative control group of 98.2g, and groups 3 to 6 were 81.2g, 90.1g, 79.9g and 55.7g, respectively. The difference between the positive control group and each experimental group was extremely significant (P<0.001). The consumption of feed, food titer, and grams of body weight per gram of food protein showed that the positive and negative controls were also higher than the four experimental groups. The average serum albumin positive control group was 3.4 g/dl, and the four experimental groups were 2.5 to 2.7 g/dl (P<0.001). No significant difference was found in hemoglobin and hepatic nitrogen in each group. Liver weight varies with body weight and is also significantly higher in the control group than in other groups.
