Effects of Inositol Supplemental Level on Growth Performance, Fur Quality, Immune Organ Indices and Nutrient Availabilities of 2 to 4-Month-Old Growing Rex Rabbits
摘要
Abstract
This experiment was conducted to study the effects of inositol supplemental level on growth perform-ance, fur quality, immune organ indices and nutrient availabilities of 2 to 4-month-old growing Rex rabbits.A total of 88 two-month-old healthy growing Rex rabbits with the similar body weight were randomly divided into 4 groups with 22 replicates per group and 1 rabbit per replicate.Group Ⅰ was used as control group and the rabbits were fed with a basal diet.Groups Ⅱ, Ⅲ, Ⅳ were used as experimental groups and the rabbits were fed with the basal diet plus 25, 50 and 75 mg/kg inositol, respectively.The experiment lasted for 60 days.The results showed as follows: 1 ) dietary inositol supplemental level had no significant effects on average daily gain, average daily feed intake and feed/gain ( P>0.05) .2) Dietary inositol supplemental level had no signifi-cant effects on fur area and fur weight ( P>0.05) , while it had significant effects on wool density and wool length ( P<0.05 or P<0.01) .The wool length in groupⅢwas the longest, and it was significantly longer than that in groupⅠ( P<0.05) , but no significant difference was found between groupsⅢandⅣ( P>0.05);the wool density in groupⅣwas the biggest, and it was significantly longer than that in groupsⅠ( P<0.05) ,Ⅱ( P<0.01) andⅢ ( P<0.05) .3) Dietary inositol supplemental level had no significant effect on spleen index ( P>0.05) , but thymus index showed an increased trend with inositol supplemental level increasing ( P>0.05) . 4)Dietary inositol supplemental level had significant effects on the availabilities of dry matter, gross energy and crude protein ( P<0.05 or P<0.01) , while it had no significant effects on the availabilities of crude fiber, neu-tral detergent fiber and acid detergent fiber ( P>0.05) .The dry matter availability in groupⅣwas the highest, which was significantly higher than that in groupⅠ( P<0.05);the gross energy availability in groupsⅡandⅣ was significantly higher than that in groupⅠ( P<0.05 or P<0.01);the crude protein availability in groupsⅡ,Ⅲand Ⅳwas significantly higher than that in group Ⅰ (P<0.05 or P<0.01).Considering all indices of this experiment, the optimum dietary inositol supplemental level is 75 mg/kg for growing Rex rabbits.关键词
