Objective To study the change of the antioxidative function of intestinal tract in semi-starvation rats and the effects of supplementation of protein diet on it. 目的研究半饥饿大鼠肠道抗氧化功能的变化及补充蛋白质对其抗氧化功能的改善作用。
The study indicated primarily that alfalfa diet in layer hens could descend mortality and feed / egg ratio, improve egg production, egg quality and intestinal performance, increase the economical benefit. The 6 % alfalfa diet was the best add ratio. 本试验研究初步表明:蛋鸡日粮中添加苜蓿草粉能够降低死淘率和料蛋比,提高产蛋性能和蛋品质,改善肠道功能,发挥良好的经济效益,添加比例以6%为最佳。
Effect of Xylanase on intestinal amino acids and peptides transporters mRNA expression in yellow-feathered broiler fed with wheat-based diet 小麦型饲粮添加木聚糖酶对黄羽肉鸡肠道氨基酸、小肽转运载体mRNA表达的影响
Their expression is related with age, location of the intestinal tract and the daily cycle. And their expression is also influenced by diet, hormones, the change of electrophysiology in the environment around, the concentration of the substrate and other factors. 其表达与年龄、肠道部位、日周期节律等因素有关,并受到饮食、激素分泌、周围电生理变化以及底物浓度等多种因素的影响。
The results were drawn as follows : 1. Intestinal microflora of geese in next days is effected by corn feed forms of the starter diet in early days. 2. 结果显示:1、饲养后期鹅的肠道微生物区系受到饲养前期玉米形态的影响。
