【摘要】 <正> 在《亚麻饼在蛋用鸡生长阶段日粮中应用的研究》一文中已阐明在生长鸡日粮中可用亚麻饼替代鱼粉。关于产蛋母鸡日粮中加用亚麻饼的研究报道不多,Vogt(1979)两次试验证明在产蛋鸡日粮中加入3.6%或12%亚麻饼,使产蛋率降低6%;当日粮中补加0.05—0.1%赖氨酸,则可纠正此缺点。本试验系用1981年与1982年两批试验的鱼粉日粮组与亚麻饼日粮组保留下的147日龄星杂288来航母鸡,继续饲喂至501日龄,研究亚麻饼替代日粮中鱼粉对母鸡产蛋性能的影响。更多还原

【Abstract】 In 1981 and 1982 linseed meal was used in the ration to replace fishmeal for feeding Xin Zha 288 White Leghorn laying hen. During the 357 days of experimentation, the average total egg weight and the average number of laying eggs of each hen of the linseed meal group were less than those of the fishmeal group by 6—9% and 8—7% respectively, but the costs of the ration for 1 kg egg of the linseed meal group were 34—38% cheaper than those of the fishmeal group. In the metabolic experiment of 1981, the retention of ration protein and the protein utilization for laying eggs of the linseed meal group were less than those of the fishmeal group, but in the comparative slaughter experiment in 1981 there was no significant difference in the protein and fat contents of the laying hen between the two groups (P>0.05) . From the results of the twoyear experiments it may be concluded that linseed meal can be used to replace fishmeal in the ration of the white Leghorn laying hens, particularly in North-West China where fishmeal is very scanty and expensive, while linseed meal is very cheap and abundant in local supply.更多还原
