| 1 | Effects of Dietary Vitamins A,B_2,and B_6 Supplementation on Growth and Feed Utilization of Juvenile Chinese Soft-shelled Turtle Pelodiscus sinensis according to an Orthogonal Array Experiment显示文摘An orthogonal experimental design OA_9(3~3) was used to evaluate the effects of vitamins(A, B_2, and B_6) on the growth and digestive ability of the juvenile Chinese soft-shelled turtle, Pelodiscus sinensis(initial weight, 5.9±0.2 g). A total of 135 turtles were divided into 9 groups, which each included 15 individuals. The results revealed that vitamin A(VA) had the strongest impacts on the growth rate and feed utilization among the three vitamins; 35,000 IU kg^(-1) VA had optimal effects on the feeding intake and specific growth rate, and 20,000 IU kg^(-1) VA had optimal effects on protein digestibility and the feed conversion ratio. Vitamin B_2(VB_2) was essential for regulating protein deposition and the energy efficiency for growth of the turtles; 120 mg kg^(-1) VB_2 resulted in increased protein and energy deposition, and 180 mg kg^(-1) VB_2 had greater beneficial effects on the growth rate. Vitamin B_6(VB_6) had important effects on protein and feed efficiency; however, VB_6 at an excessive level(120 mg kg^(-1)) restricted turtle growth. Based on the above growth results, dietary supplementation of VA, VB_2 and VB_6 at levels of 35,000 IU kg^(-1), 180 mg kg^(-1) and 70 mg kg^(-1), respectively, were recommended for the juvenile soft-shelled turtle. | Junwei LI Zhencai YANG Xiaoling HAN Quansen XIE Haiyan LIU | 2016 | Asian Herpetological Research2016，7，4： | 2 |
