摘要

本试验以765窝新西兰白兔(NZW)品种为试验对象,对影响奶类性状的因素进行了为期5年的研究。在研究的大部分周内,点燃季节对产奶量和总产奶量的影响显著较高。胎次对产奶量、第1周、第3周产奶量和总产奶量的影响不显著,但随着胎次的增加,产奶量逐渐增加

FACTORS AFFECTING MILK PRODUCTION AND USING APPLICATION SELECTION INDICES TO IMPROVE PRODUCTIVE TRAITS OF DOES IN NEW ZEALAND WHITE RABBITS.
This study was carried out on 765 litters of New Zealand White(NZW)rabbit breed and extended for about 5years to study some factors affecting milk traits. The effect of season of kindling on milk production was higher significantly during most of the weeks of the study and total milk yield. The insignificant effect of parity on milk production and the milk yield during 1 st , 3 rd week and total milk yield but increased gradually with the advancement of parity from 1 st to 3 rd
