Effects of Different Levels of Pummelo Leaves in Diets on Growth Performance, Total Tract Apparent Digestibility of Nutrients in Diets and Slaughter Performance of Growing Rabbits
摘要
Abstract
The aim of this study was to investigate the actual feeding effects of diets containing different levels of pummelo leaves for growing rabbits and recommend the best level of pummelo leaves in rabbit diets. A total of 120 healthy and 35-day-old French IRA rabbits with the same genetic background and similar weight were used in a randomized design, which consisted of four groups and ten replicates in each group, three rabbits in each replicate after adaptation period. Four groups were fed different diets that had similar nitrogen, energy and fiber and the levels of pummelo leaves in the diets were 0 ( control group) , 6%( groupⅠ) , 12% ( groupⅡ) and 18% ( group Ⅲ) , respectively. The adaptation period lasted for 7 d and the experimental period lasted for 28 d. The results showed as follows:1) except for the average daily feed intake of growing rabbits in groupⅢwas significantly lower than that in group Ⅱ (P<0.05), the average daily gain and feed conversion rate of growing rabbits in control group and experimental groups had no significant differences in this study ( P>0.05) . 2) The total tract apparent digestibility of neutral detergent fiber in diets in control group and group Ⅲwas significantly higher than that in groups Ⅰ and Ⅱ (P<0.05), and the total tract apparent digestibility of ash in group Ⅱ was significantly higher than that in control group and group Ⅰ ( P<0.05) . 3) At the end of this experiment, live weight in groupⅢ was significantly lower than that in groupsⅠ andⅡ ( P<0.05) , hot carcass weight in control group was significantly lower than that in groups Ⅰ and Ⅱ ( P<0.05) , body length in group Ⅲ was significantly lower than that in other groups ( P<0.05) , and thigh circumference in groupsⅠand Ⅲwas significantly lower than that in groupⅡ( P<0.05) . In conclusion, the diets containing 6% to 18%pummelo leaves have no adverse effects on growth performance, total tract apparent nutrient digestibility and slaughter performance of growing rabbits, and the best level of pummelo leaves in rabbit diets is 12%.关键词
