饲料原料对蛋鸡生产性能和鸡蛋品质的影响

用三种来源不同的饲料饲喂商品蛋鸡,分别是全玉米豆粕饲料(A组)、河北购进的典型商品饲料(B组)和用杂粕配制的饲料(C组)。结果显示,A组产蛋率最高(76.8%),和C组(74.7%)差异显著(P<0.05)。平均蛋重三个组之间差异不显著。平均日耗料量A组(120.3g)低于B组(127.6g),高于C组(116g)。A组料蛋比和C组接近(2.43:1和2.42:1),均优于B组(2.63:1)。常规蛋品质三个组之间差异不显著,但是鸡蛋内容物中一些成分的含量存在差异。C组鸡蛋的水分含量稍高于A组和B组。三种鸡蛋中有毒有害物质含量均低于国家要求的标准,鸡蛋中没有检测出细菌。

Effects of Feed on Productive Performance and Eggs Quality of Laying Hens

Three types of feeds was use to feed commercial laying hens.Group A feed on all corn-soybean feed,while group B feed on the typical feed bought from Heibei province and groupC using the feed containing vegetable seeds.The results showed that group A had the highest egg production percentage(76.8%)and significant higher than group C(74.7%,P<0.05).Feed intake per hen was120.3g for group A,lower than group B(127.6g),and higher than group C.FRC of group A was similar to that of group C(2.43vs.2.42),both superior to group B(2.63:1).Difference of general egg qualities among three groups was insignificant,but some component containing in eggs had significant difference.Water percentage in eggs of group C was higher than group A or group B.Content of venomousness material and injurant were all lower than state standard and no bacterium check out in the eggs.
