不同蛋白日粮对山羊瘤胃环境参数的影响

Effect of different protein diets on rumen fermentation of goats

试验采用4×3拉丁方试验设计,研究豆粕、棉籽粕、菜籽粕、玉米酒糟4种不同蛋白质日粮对3只徐淮白山羊瘤胃发酵参数的影响。结果表明,4种不同蛋白源日粮对山羊瘤胃内环境有显著的影响,玉米酒糟组pH值最高;豆粕和棉籽粕组氨氮浓度与玉米酒糟组相比差异显著(P<0.05),与菜籽粕组相比差异极显著(P<0.01);4种蛋白源的瘤胃总VFA浓度分别为87.44、66.67、80.63、82.73mmol/l,其中以豆粕组最高,显著高于菜籽粕组(P<0.05),极显著高于棉籽粕组(P<0.01);以棉籽粕组最低,极显著低于其它3组。

The study comprised four different samples of protein diets [A： soybean treatment, B： cottonseed treatment, C： rapeseed treatment, D： dried distillers grain with soluble （DDGS） treatment]. The main objective were to determine the effects of different protein diets on rumen fermentation by 4 ×3 Latin square. The result indicated that four different protein diets might significantly affect rumen fermentation. The highest index of pH was in D; The ammonia nitrogen density of A and B was significantly different from D （P〈0.05）, was striking significantly different from group C （P〈0.01）; The total VFA density of tureen were 87.44,66.67,80.63,82.73 mmol/1 respectively, but A was the highest, it was significantly higher than C（P〈0.05）, striking significantly higher than group B（P〈0.01）. B was lowest in the four treatments and striking significantly lower than the others.
