籽粒苋青贮饲喂对产蛋鹅生产性能的影响

为了为我国北方寒冷地区冬季产蛋鹅青绿饲料来源开辟一条新的途径，在籽粒苋Amaranthu paniculatus引种、栽培等试验基础上，进行了籽粒苋青贮试验及青贮籽粒苋饲喂产蛋鹅试验。试验表明，在我国北方寒冷季节对籽粒苋进行青贮调制简单可行，青贮的籽粒苋营养价值有所提高，适口性有所改善；显著提高了产蛋鹅的产蛋率、种蛋率和料蛋比，降低了畸形蛋率和破蛋率，对仔鹅、种蛋受精率、孵化率和健雏率无影响。结果表明，种植籽粒苋进行青贮，用来冬春季饲喂产蛋鹅，可有效解决寒冷地区冬季产蛋鹅青绿饲料不足的问题，降低饲料成本，提高养鹅经济效益。

Effect of amaranth silage on performance of laying geese

Looking for a new way on green fodder for laying geese in winter of northern China,following the introduction and cultivation of amaranth,the effect of amaranth silage on performance of laying geese was conducted.The results showed that it was feasible to make amaranth silage in winter;the nutrient quality and feeding value were improved.Compared with the control group,the laying rate,breeding egg rate and feed conversion efficiency increased markedly;while abnormal egg rate and broken egg rate decreased.There were no difference in fertilized egg rate,hatchability rate and the rate of breed goose between the control and experimental group.The use of amaranth silage may solve the problem of green fodder shortage in winter,and improve the economic profit of haying geese.
