板栗蜂花粉对五龙鹅繁殖性能影响的试验研究

Experimental Study on the Effect of Chestnut Bee Pollen on Breeding Performance of Geese

为检验板栗蜂花粉能否作为繁殖鹅饲料及其合适的添加比例,本试验选取216只90周龄的五龙鹅,公母比例为1:2,随机分为4组,每组54只分成3个重复,其中对照组饲喂基础日粮,3个试验组分别在日粮中添加0.5%、1.0%和1.5%的板栗蜂花粉,进行28d饲养试验。结果显示,添加1.5%的板栗蜂花粉可不同程度提高公鹅的精液量、精子浓度、减少畸形率(P<0.05),不同程度提高公鹅血液雌二醇、促卵泡素、睾酮浓度(P<0.05);不同程度提高母鹅产蛋量、雌二醇、促卵泡素浓度、孕酮浓度(P<0.05),但不能提高母鹅单枚蛋重(P>0.05)。试验表明添加一定比例的板栗蜂花粉能提高鹅繁殖性能,并有助于提高机体免疫力。

In this study,whether the chestnut bee pollen as breeding geese feed and suitable addition ratio were tested.216 90-week-old Wulong geese were selected,male and female ratio of 1：2,randomly divided into four groups,each group 54 is divided into three replicates.One group was fed the basal diet control group,three experimental groups were in the diet added 0.5%,1.0%,1.5%of the chestnut bee pollen.After 28 d feeding trial,the results showed that1.5%of the chestnut bee pollen could improve the gander semen volume,sperm concentration,reduce deformity rate（P〈0.05）,and improve to varying degrees gander blood estradiol,estradiol,testosterone concentrations（P〈0.05）;different degrees to improve the goose egg,estradiol,follicle-stimulating hormone concentrations（P〈0.05）,but not in single eggs weight,testosterone concentrations（P〈0.05）.Tests showed that adding a certain concentration chestnut bee pollen can improve the reproductive performance of geese and helps to improve immunity.
