摘要
采用同胞配对设计，用改进的配方和饲料加工工艺调配的水貂干粉料，与改进前的配合料，对当年生水貂的生长发育和毛皮质量的影响进行了对比试验。结果表明，试验组水貂食欲、消化和生长发育正常，无尿结石病发生，食毛和自咬症减少。体重和体长性状与对照组无显著性差异（Ｐ＞０．０５）。貂皮尺码和皮张质量优良。公貂皮６５ｃｍ以上者比对照组高１７．７％，甲级皮率提高６．１％，次级皮率减少２．１％。母貂皮５３ｃｍ以上者和甲级皮率分别比对照组提高７．８％和１．８％。
Dry powder feed compounded according improved prescription and process technology, and original feed were used to make a compared experiment on growth and fur quality of mink bore the same year. The paired design was used in this experiment. The quanlity of fish powder of treatment group was 24.73% reduced in growth period and 50% reduced in growth period of winter .hair. The result showed that the appetite. digestion and growth of mink in treatment group were normal, and there was no disease of urinary calculus. Eat hair and eatself diseases were reduced. The body weight and length were no remarkable different to comparison group (P>0.05). The fur length and quality were good. The fur rate of male mink above 65cm was 17.7% higher than comparison group. The rate of first grade fur of mink was 6.1% increased, and the rate of not up to required standard was 2.1 % reduced. .The fur rate of female mink above 53cm and the rate of first grade were 7.8% and 1 .8% higher than comparison group.
