| Abstract: | This experiment was conducted to study the effects of normal corn replacement by high amylose corn on growth performance,nutrient apparent digestibility and blood biochemical and physiological indexes of weaning goats.Twenty-seven Xiangdong black goats with an average body weight of(8.97±0.19)kg were divided into 3 groups with 4 male goats and 5 female goats and each of them was raised in a single column.The weaning goats in the 3 groups were fed experimental diets,and the experimental diets were formulated by replacing 0(A group,as control group),50%(B group)and 100%(C group)normal corn with high amylose corn,respectively.Preliminary period lasted for 7 d,and test period lasted for 28 d.The results showed that,compared with control group,the average daily gain in B and C groups was significantly increased(P<0.05),as well as the apparent digestibility of dry matter,crude protein,neutral detergent fiber(NDF)and acid detergent fiber(ADF)was significantly improved(P<0.05).The contents of serum vascular endothelial growth factor(VEGF)and lactic acid(LAC)in B group were higher than those of control group,but the differences were not significant(P>0.05);however,the contents of serum VEGF and LAC in C group were significantly higher than those of control group(P<0.05).In conclusion,the replacement of 50%or 100%normal corn with high amylose corn in weaning goats’diets have a positive effect on growth and nutrient digestibility. |
