The effect of two milk diets on the changes in selected parameters of energy metabolism was studied in calves. After the termination of colostrum feeding, the experimental group of calves (n = 10) was given whole milk whereas the calves in the control group (n = 10) were given the Laktosan milk replacer. Blood was collected for biochemical investigation from the third day of age (determination of glucose concentration) and from the fourth week of age (evaluation of the parameters of lipid metabolism). The plasma concentrations of glucose were about the same in both groups of calves throughout the period of study. The total lipid, total cholesterol and triglyceride levels in blood serum were significantly higher in the calves of the experimental group during the milk feeding period; later they did not differ significantly from the values determined in the control calves. On the other hand, the concentrations of non-esterified fatty acids were higher in the calves of the control group in the milk feeding period; the differences, however, are not statistically significant. The average daily weight gains from the 5th to the 18th week of age were significantly higher in the calves given whole milk.
研究了两种乳类日粮对犊牛能量代谢选定参数变化的影响。在初乳饲喂结束后，给实验组犊牛（n = 10）喂全脂牛奶，而给对照组犊牛（n = 10）喂Laktosan代乳品。从犊牛3日龄（测定葡萄糖浓度）和4周龄（评估脂质代谢参数）采集血液进行生化研究。在整个研究期间，两组犊牛的血浆葡萄糖浓度大致相同。在喂乳期，实验组犊牛血清中的总脂质、总胆固醇和甘油三酯水平显著高于对照组；之后，它们与对照组犊牛所测值无显著差异。另一方面，在喂乳期，对照组犊牛的非酯化脂肪酸浓度较高；然而，差异无统计学意义。5至18周龄期间，喂全脂牛奶的犊牛平均日增重显著更高。
