| 摘 要： | 采用3×3因子的析因设计,将189只1日龄健康肉用仔鹅随机分成9组,每组3个重复,每个重复7只;将日粮的粗纤维和粗蛋白分前、后期各设低、中、高3个水平,构成9个处理,18种日粮,研究不同粗纤维和粗蛋白水平对1~35日龄(前期)、36~63日龄(后期)肉仔鹅生长性能和营养物质利用率的影响。结果:1~35日龄肉仔鹅对日粮中粗纤维水平非常敏感,但对蛋白质水平要求不高;低纤维水平日粮组日增重与料重比明显好于中、高纤维组(P<0.01),日粮粗纤维和粗蛋白水平极显著影响鹅对能量和蛋白质的利用率(P<0.01);1~35日龄肉仔鹅饲粮粗纤维水平以3.5%、粗蛋白水平以17%~19%为宜。36~63日龄,较低的粗蛋白水平即可满足鹅的需要;高纤维水平日粮组鹅的日增重与料重比明显好于低纤维水平组(P<0.01);日粮粗纤维和粗蛋白水平极显著影响鹅对能量和蛋白质的利用率(P<0.01)。试验表明36~63日龄肉仔鹅饲粮适宜粗纤维水平为10%,粗蛋白水平为14%。

| Abstract: | A 3×3 factorial experiment was designed to investigate the effect of diets with different CF and CP levels on the growth performance and availability of nutrients in meat geese aged from 1 to 63 days.One hundred eighty-nine meat geese of 1 day-old were randomly divided into 9 groups,each containing 3 replicates and 7 geese per replicate.The experiment was divided into two period(1~35 day and 36~63 day periods).In each period,geese were fed with 9 diets respectively with different CF and CP levels.During the 1~35 day period of experiment,the daily gain of low dietary CF levels groups were great significantly higher than that of others(P<0.01) and had the lowest F/G.Dietary CP levels had no significant effect on daily gain and F/G(P>0.05).Dietary CF and CP great significantly influenced the availability of energy and protein of young geese(P<0.01).During the 36~63 day period,the daily gain and the F/G of high dietary CF levels groups were great significantly better than that of low dietary CF levels groups(P<0.01);the daily gain of 14% and 16% CP levels groups were significantly higher than that of 18% CP level groups(P<0.05),and 14% CP level groups had the best F/G;dietary CF and CP great significantly influenced the availability of energy and protein of young geese(P<0.01).Therefore,the levels of 3.5% CF and 17%~19% CP and the 10% CF and 14% CP in diets were proper for meat geese aged from 0 to 35 days and 36 to 63 days,respectively. |
