摘要
选用45日龄Vc-Ⅱ新品系獭兔54只,研究维生素A水平对獭兔生产性能及血液生化指标的影响。结果表明,在基础日粮中添加10000IU/kg维生素A可显著提高獭兔的日增重(P<0.05)、降低料肉比(P>0.05)、降低血清BUN含量(P<0.01)。建议VC-Ⅱ生长獭兔日粮中维生素A的添加量为10000IU/kg。
The purpose of the trail was to investigate the effects of Vitamin A levels on production perfomance and biochemical parameters in Rex rabbits.Results showed that average daily gain was improved,and feed/gain and serum SUN were decreased in 10 000IU/kg supplemented on basal dietary.It is suggested that suitable additive level of Vitamin A in dietary was 10 000IU/kg in Vc-Ⅱgrowing Rex rabbits
