【摘要】：本试验旨在研究饲粮中核黄素添加水平对生长獭兔肉品质、毛囊发育和免疫性能的影响。选择体重相近的3月龄獭兔160只,随机分为4组,每组40个重复,每个重复1只兔。各组分别饲喂在基础饲粮中添加0(对照)、3、6和12 mg/kg核黄素的饲粮。预试期7 d,正试期53 d。结果表明:与对照组相比,饲粮中添加6、12 mg/kg核黄素显著降低了獭兔肌肉的滴水损失(P0.05),饲粮中添加3、6、12 mg/kg核黄素显著提高了獭兔皮肤中总毛囊密度(P0.05),饲粮中添加3、6 mg/kg核黄素显著提高了獭兔皮肤中初级毛囊密度(P0.05),饲粮中添加6、12 mg/kg核黄素显著提高了獭兔皮肤中次级毛囊密度(P0.05),饲粮中添加3、6 mg/kg核黄素显著降低了獭兔皮肤中次级毛囊密度/初级毛囊密度(P0.05)。饲粮中核黄素添加水平对獭兔的胸腺重、胸腺指数及血清免疫球蛋白G、免疫球蛋白A、白细胞介素-2含量影响显著(P0.05),且均随着饲粮中核黄素添加水平的升高呈先增加后降低的趋势,并均在6 mg/kg添加组中达到最大值,显著高于对照组(P0.05)。由此可见,3~5月龄生长獭兔饲粮中核黄素适宜添加水平为6 mg/kg(实际测定饲粮中核黄素水平为8.35 mg/kg)。
[Abstract]:The purpose of this study was to study the effects of riboflavin supplementation on meat quality, hair follicle development and immune performance of growing Rex rabbits. 160 rabbits of 3 months old with similar body weight were randomly divided into 4 groups, 40 replicates in each group. Each rabbit was fed with a diet supplemented with 0 (control group) with riboflavin for 3 and 12 mg/kg, respectively. The pretest period was 7 days, and the trial period was 53 days. The results showed that: compared with the control group, The addition of riboflavin for 6 ~ 12 mg/kg significantly reduced the drop water loss of muscle of Rex rabbits (P 0.05N), the total hair follicle density of Rex rabbits was increased significantly by adding riboflavin for 612 mg/kg in diet, and the skin of Rex rabbits was increased by adding riboflavin for 36 mg/kg in diet. The density of secondary hair follicles in the skin of Rex rabbits was significantly increased by adding 6 ~ 12 mg/kg riboflavin to diet, and the density of secondary hair follicles / primary hair follicle density of Rex rabbits was significantly decreased by adding 3 ~ (6) mg/kg riboflavin to diet. The ratio of secondary hair follicle density to primary hair follicle density in Rex rabbit skin was significantly decreased by feeding with 3 ~ 6 mg/kg riboflavin. The effect of Riboflavin supplementation on thymus weight in Rex Rabbits, The thymus index, serum immunoglobulin G, immunoglobulin A and interleukin-2 contents were significantly affected by P0.05N, and they all increased first and then decreased with the increase of dietary riboflavin supplementation level, and reached the maximum value in 6 mg/kg supplementation group. It can be seen that the appropriate level of riboflavin in the diet of 3 ~ 5 months old growing Rex rabbits is 6 mg / kg (the actual level of riboflavin in diet is 8.35 mg / kg 路kg ~ (-1)).
