营养强化低脂羊奶粉对幼龄动物生长发育及血脂的影响

目的]研究营养强化低脂羊奶粉对幼龄动物生长发育及脂肪含量的影响。方法]给予幼龄SD大鼠营养强化低脂羊奶粉,试验周期42 天。测定动物生长发育指标（体重、体长）、食物利用率、甘油三酯、胆固醇,及体内脂肪和股骨骨密度。结果]营养强化低脂羊奶粉组与空白组比较,生长发育指标（体重、体长）无不良影响,股骨骨密度明显升高（P<0.01）,营养强化低脂羊奶粉对体脂无明显影响。结论]营养强化低脂羊奶粉可促进幼龄SD大鼠骨骼生长,对血脂含量及体脂率无影响。

Effects of Nutrient-enriched Low Fat Goat Milk Powder on Growth and Blood Lipid of Young Animals

Objective]To study the effects of nutrient-enriched low fat goat milk powder on growth and fat content of young animals.Method]Young SD rats were treated nutrient-enriched low fat goat milk powder,and the experiment period was maintain for 42 days.Growth and development indexes（body weight,body length）,food utilization rate,triglyceride,cholesterol,body fat and bone density of femur were measured.Result]Compared with the blank group,the nutrient-enriched low fat goat milk powder group has no obvious adverse effects on body weight and body length,and no significant effect on body fat,but the bone mineral density of femur was significantly increased（P <0.01）.Conclusion]Nutrient-enriched low fat goat milk powder can promote the growth and development of young rats,promote bone growth,but has no effect on the content of blood lipid and body fat percentage.
