摘要

本试验旨在研究饲粮维生素B₆添加水平对生长獭兔生长性能、皮张质量、肌肉品质以及维生素B₆代谢的影响。试验选用200只体重相近、健康状况良好的3月龄獭兔,随机分成5组,每组40个重复,每个重复1只,分别饲喂在基础饲粮基础上添加0(对照)、5、10、20和40 mg/kg维生素B₆的试验饲粮。预试期7 d,正试期53 d。结果表明:饲粮维生素B₆添加水平对平均日增重有显著影响(P=0.017 8),对平均日采食量有极显著影响(P=0.000 4),二者均在维生素B₆添加水平为20 mg/kg时达到最高值。随着维生素B₆添加水平的升高,料重比(F/G)有先降低后升高趋势,并在维生素B₆添加水平为20 mg/kg时达到最低值。饲粮维生素B₆添加水平对獭兔皮张重量有显著影响(P=0.040 0),对皮张面积有极显著影响(P=0.001 6),对皮张厚度和被毛长度无显著影响(P=0.478 0和P=0.756 2)。20 mg/kg添加组的皮张重量、皮张面积显著或极显著高于对照组(P < 0.05或P < 0.01)。饲粮维生素B₆添加水平显著或极显著影响肌肉pH(P=0.039 4)、红度值(a^*)(P=0.013 1)、黄度值(b^*)(P=0.023 9)、亮度值(L^*)(P=0.002 5),其中20 mg/kg添加组的L^*极显著低于对照组(P < 0.01),b^*显著低于对照组(P < 0.05),a^*显著高于对照组(P < 0.05)。饲粮维生素B₆添加水平对肌肉失水率和剪切力无显著影响(P=0.216 1和P=0.825 9)。饲粮维生素B₆添加水平对肌肉中维生素B₆含量有显著影响(P=0.028 3),对肝脏和尿液中维生素B₆含量有极显著影响(P=0.000 1和P=0.008 1),对血清中维生素B₆含量无显著影响(P=0.112 9)。20 mg/kg添加组肌肉和肝脏中维生素B₆含量显著或极显著高于对照组(P < 0.05或 P < 0.01)。综合本试验测定指标,3~5月龄生长獭兔饲粮适宜的维生素B₆添加水平为20 mg/kg。

Abstract

This experiment was conducted to investigate the effects of dietary vitamin B₆ supplemental level on growth performance, fur quality, muscle quality and vitamin B₆ metabolism of growing Rex rabbits. Two hundred 3-month-old healthy Rex rabbits with similar body weight were randomly divided into 5 groups with 40 replicates in each group and each replicate contained 1 rabbit. Rabbits in 5 groups were fed experimental diets containing 0 (control), 5, 10, 20 and 40 mg/kg vitamin B₆, respectively. The trial lasted for 7 days for adaptation, and 53 days for test. The results showed that dietary vitamin B₆ supplemental level had significant influence on average daily gain (ADG) and average daily feed intake (ADFI) (P=0.017 8 and P=0.000 4, respectively), and the highest values of ADG and ADFI were found when vitamin B₆ supplemental level was 20 mg/kg. With the vitamin B₆ supplemental level increasing, the feed/gain (F/G) was firstly decreased and then increased, and it had the lowest value when vitamin B₆ supplemental level was 20 mg/kg. Dietary vitamin B₆ supplemental level had significant influences on fur weight and fur area (P=0.040 0 and P=0.001 6, respectively), but had no significant influences on fur thickness and wool length (P=0.478 0 and P=0.756 2, respectively). The fur weight and fur area in 20 mg/kg group were significantly higher than those in control group (P < 0.05 or P < 0.01). Dietary vitamin B₆ supplemental level had significant influences on pH (P=0.039 4), red value (a^*) (P=0.013 1), yellow value (b^*) (P=0.023 9) and light value (L^*) of muscle (P=0.002 5). The muscle b^* and L^* were significantly lower than those in control group (P < 0.05 or P < 0.01), while the muscle a^* was significantly higher than that in control group (P < 0.05). Dietary vitamin B₆ supplemental level had no significant influences on muscle water loss rate and shear force (P=0.216 1 and P=0.825 9, respectively). Dietary vitamin B₆ supplemental level had no significant influences on vitamin B₆ content in muscle, liver and urine (P=0.028 3, P=0.000 1 and P=0.008 1, respectively), but had no significant influence on vitamin B₆ content in serum (P=0.112 9). The muscle and liver vitamin B₆ contents in 20 mg/kg group were significantly higher than those in control group (P < 0.05 or P < 0.01). Considering all indexes of this experiment, the appropriate vitamin B₆ supplemental level is 20 mg/kg for 3 to 5-month-old growing Rex rabbits.
