Effect of Dietary Fiber Level on Body Condition Development,Apparent Nutrient Digestibility and Reproductive Performance of Breeding Male Rabbits
The purpose of this study was to explore the effects of dietary fiber levels on the growth performance,apparent digestibility and reproductive performance of Yila male rabbits.Using the single factor design,twenty 60-day-old male Yila rabbits were randomly divided into 4 treatment groups with 5 replicates in each group and 1 rabbit per repetition.The fiber levels were 10%,12%,14% and 16%,respectively.The pre-feeding period was 7 days and the experimental period was 90 days.The results showed as follows:1)Male living weight in 12% group at 90 days of age and 150 days of age was significantly higher than that in 10% and 16% groups(P<0.05);The ratio of feed to gain of male rabbits in 14% and 16% groups at 90 days of age was significantly higher than that in 10% and 12% groups(P<0.05).2)The apparent digestibility of dry matter,crude protein and digestibility of male rabbits in 12% group was significantly higher than that in 10% and 16% groups;The crude fiber apparent di-gestibility of male rabbits in 12% and 14% groups was significantly higher than that in 10% and 16% groups(P<0.05).3)The sperm density of male rabbits in 14% and 16% groups was significantly higher than that in 10% and 12% groups,the sperm viability of male rabbits in 14% group was significantly higher than that in other group(P<0.05).Thus it can be seen that the appropriate dietary fiber level can increase the body weight gain and improve the reproductive performance of male rabbits.In this experiment,the suitable level of crude fiber in the diet of male rabbits before 120 days of age is 12%,and that of crude fiber after 120 days of age is 14%.
