畜禽粪便养殖蚯蚓试验

随着专业户养畜业的发展,深感蛋白质饲料源不足,为此,进行了利用畜禽粪便养殖蚯蚓、提供动物性蛋白质饲料源的试验。以前的试验,多用发酵粪便养殖蚯蚓。我们采用了三种处理的牛、猪、鸡粪养殖蚯蚓。试验结果指出,发酵牛粪加10%的发酵鸡粪,蚯蚓繁殖最好;发酵牛粪,风干牛粪和100℃烘干牛粪,蚓蚓繁殖较好;而发酵鸡粪,经两次投蚓,都在两小时内死亡,100℃烘干猪粪两次投蚓都在一周左右死亡,不能繁殖蚯蚓。这样,大型牛场可以采用速干牛粪养殖蚯蚓,减少粪便污染环境时间。对于专业户来说,可随时干燥牛粪来繁殖蚯蚓,提供蛋白质饲料来源。

An Experiment for Earthwarm Feeding and Reproduction

with the development of family farming of animal husbandary in rural area,the feeding stuffs of animal protein concentrates are badly needed now.The experiment for earthwarm feeding and reproduction with animal feces were conducted so as to provide a supplement source of animal protein concentrates. Fermented feces were used to feed and reproduce earthwarms in previous studies.Three treatments with feces voided by catt le,pigs and poultry were applied in this study on earthwarm feedi ng and reproduction. The results show that the earthwarms reproduced best in the fermented cattle dung plus 10 per cent of fermented chicken droppings and they did better in cattle dung fermented,air dried and dried in oven with 100℃ respectively.But earthwarms died within two hours after putting them into fermented chicken droppings for two times. And they could not survive either in pig feces dried in oven with 100℃. It is suggested that cattle dung in large farms could be dried quickly to produce earthwarms and thos decrease the time ol environmental pollution.For the professional families of animaf husbandary,cattle dung could be dried at any time to produce earthwarms as a source of animal protein concentratest.
