摘要:

旨在探讨饲粮钙和维生素D3水平在钙磷比固定为1.4/1时对冬毛期蓝狐生产性能、胫骨发育及脏器指数的影响。135只120日龄的蓝狐公狐随机分成9组,每组15个重复,每个重复1只。试验采用3×3双因素试验设计,9组饲粮分别包含3个钙水平0%、0.4%和0.8%,3个维生素D3水平1 000、2 000和4 000 IU·kg-1。基础日粮中钙与维生素D3水平分别为0.8%与327 IU·kg-1。9种饲粮的钙与维生素D3水平分别为0.8%与1 327 IU·kg-1、0.8%与2 327 IU·kg-1、0.8%与4 327 IU·kg-1、1.2%与1 327 IU·kg-1、1.2%与2 327 IU·kg-1、1.2%与4 327 IU·kg-1、1.6%与1 327 IU·kg-1、1.6%与2 327 IU·kg-1、1.6%与4 327 IU·kg-1。试验期为87 d,分别测定蓝狐生长性能指标、胫骨的各组分含量及脏器质量,计算胫骨发育指标及脏器指数。结果表明:1)随着饲粮钙添加水平的增加,蓝狐末重和体长显著降低(P<0.05),饲粮钙添加水平为0%时,蓝狐末重和体长最大。维生素D3水平对蓝狐末重、体长和皮长均无显著影响(P>0.05)。2)随着饲粮钙添加水平的增加,蓝狐胫骨钙含量显著提高(P<0.05),饲粮钙添加水平为0.8%时,蓝狐胫骨钙含量最高。维生素D3水平对蓝狐胫骨灰分含量有显著影响(P<0.05)。3)饲粮钙的添加显著降低了心脏和肝脏指数(P<0.05)。综合以上指标,在本试验条件下,蓝狐饲粮中添加0%钙、1 000 IU·kg-1维生素D3,饲粮中总钙含量为0.8%,总维生素D3含量为1 327 IU·kg-1时,能够改善蓝狐的生产性能、增加蓝狐的体长、调节胫骨发育和脏器指数。

Abstract:

The aim of this study was to investigate the effects of dietary Ca and vitamin D3levels on growth performance, tibia development and viscera indices of growing-furring blue foxes under the condition of a fixed 1.4/1 ratio of Ca to P. One hundred and thirty-five male blue foxes of 120-day-old were randomly allocated into 9 groups, with 15 blue foxes per group. The 9 treatment diets were supplemented with 0%, 0.4% and 0.8% Ca, and they were supplemented with 1 000, 2 000 and 4 000 IU·kg-1 VD3. The experiment was conducted with a 3×3 factorial design using a basic diet that contained 0.8% Ca and 327 IU·kg-1VD3. The treatment diets contained 0.8%Ca and 1 327 IU·kg-1VD3, 0.8%Ca and 2 327 IU·kg-1VD3, 0.8%Ca and 4 327 IU·kg-1VD3, 1.2%Ca and 1 327 IU·kg-1VD3, 1.2%Ca and 2 327 IU·kg-1VD3, 1.2%Ca and 4 327 IU·kg-1VD3, 1.6%Ca and 1 327 IU·kg-1VD3, 1.6%Ca and 2 327 IU·kg-1VD3, 1.6%Ca and 4 327 IU·kg-1VD3. The test period lasted for 87 days. The growth performance, ingredient percent of tibia and viscera weight were measured, respectively and then we calculated the tibia development parameters and viscera indices of growing-furring blue foxes. The results showed that:1) The final BW and body length of blue foxes significantly decreased with increasing Ca levels(P<0.05). The maximum final BW and body length were in 0%-Ca group. There was no significant difference in final BW, body length and pelt length of blue foxes among different VD3 levels(P>0.05). 2) The Ca dosage added had a linear effect on Ca percent of the tibia(P<0.05). The maximum Ca percent of tibia was in 0.8%-Ca group. The dietary VD3 level had a significant effect on ash percent of tibia(P<0.05). 3) The heart and liver indices of blue foxes linearly decreased with increasing Ca levels(P<0.05). In conclusion,the results of this research indicated that the diet supplementation with 0%Ca and 1 000 IU·kg-1VD3(the diet contained 0.8% Ca and 1 327 IU·kg-1 VD3) could improve the growth performance, body length, and regulate the tibia development and viscera indices of growing-furring blue foxes.
