摘要
分别以高温菜籽粕、高温菜籽粕醇洗浓缩蛋白、高温豆粕醇洗浓缩蛋白、低温豆粕醇洗浓缩蛋白为主要蛋白源配制的半合成饲料进行大鼠饲喂试验,通过对大鼠生长发育和生理生化指标的检测分析,比较不同蛋白源对大鼠饲喂效果的影响,研究评价高温菜籽粕醇洗浓缩蛋白的营养功能性。结果显示:从大鼠生长发育、消化代谢、血常规、血生化及蛋白质营养价值等指标综合比较,高温菜籽粕醇洗浓缩蛋白组>高温菜籽粕组>低温豆粕醇洗浓缩蛋白组>高温豆粕醇洗浓缩蛋白组;高温菜籽粕醇洗浓缩蛋白组的谷丙转氨酶(ALT)、尿酸(UA)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)在4组中最低,抗动脉粥样硬化指数(AAI)最高,说明高温菜籽粕醇洗浓缩蛋白组的大鼠较其他组的患糖尿病和动脉硬化的概率要低。因此,高温菜籽粕醇洗浓缩蛋白是优质的饲料蛋白源。
Rats were fed with semisynthetic feeds prepared with high temperature rapeseed meal, high temperature alcohol washed rapeseed protein concentrate, high temperature alcohol washed soybean pro- tein concentrate and low temperature alcohol washed soybean protein concentrate as the main protein sources respectively. The growth, physiological and biochemical indexes of rats were detected and ana- lyzed to compare the effects of different protein sources so as to evaluate the nutritional function of high temperature alcohol washed rapeseed protein concentrate. The results showed that according to the com- prehensive comparisons of the growth, digestion and metabolism, blood routine and blood biochemical in- dexes of rats and nutritional value of protein, the group of high temperature alcohol washed rapeseed pro- tein concentrate was the best, followed by the groups of high temperature rapeseed meal, low temperature alcohol washed soybean protein concentrate and high temperature alcohol washed soybean protein concen- trate; the levels of aminotransferase （ALT）, uric acid （UA） , triglyceride （TG） and low density lipopro- tein cholesterol （ LDL - C） of rats in the group of high temperature alcohol washed rapeseed protein con- centrate were the lowest, and anti - atherosclerotic index （AAI） of rats was the highest among the four groups, which indicated that the rats in the group of high temperature alcohol washed rapeseed protein concentrate had lower risk of diabetes and atherosclerosis than the other three groups. Therefore, high temperature alcohol washed rapeseed protein concentrate was a high quality feed protein source.
