【摘要】：本试验旨在研究饲粮添加维生素E和酵母硒对黄羽肉种鸡产蛋性能、孵化性能及蛋中维生素E和硒(Se)沉积量的影响。试验采用3×3双因子设计,设3个维生素E添加水平(0、20、40 IU/kg)和3个Se添加水平(0、0.15、0.30 mg/kg)。选用32周龄快大型岭南黄羽肉鸡父母代种母鸡864只,根据产蛋率和体重一致性原则随机分成9个组,分别为VE_0Se_0组、VE_0Se_(0.15)组、VE_0Se_(0.30)组、VE_(20)Se_0组、VE_(20)Se_(0.15)组、VE_(20)Se_(0.30)组、VE_(40)Se_0组、VE_(40)Se_0.15组和VE_(40)Se_0.30组,每组6个重复,每个重复16只鸡。试验期8周。结果表明:1)饲粮中维生素E和Se添加水平对黄羽肉种鸡的体增重、平均日产蛋量、料蛋比、平均蛋重、产蛋率、破蛋率和不合格蛋率均无显著影响(P0.05)。2)饲粮中维生素E和Se添加水平对黄羽肉种鸡的蛋长径、蛋短径、蛋白高度、蛋黄颜色、哈氏单位、蛋黄重、蛋壳重和蛋壳厚度均无显著影响(P0.05)。3)饲粮中维生素E和Se添加水平对黄羽肉种鸡的健雏出壳重、孵化率、弱雏率和受精率均无显著影响(P0.05)。4)饲粮中维生素E添加水平对黄羽肉种鸡血浆MDA含量有显著影响(P0.05),随饲粮中维生素E添加水平的升高血浆MDA含量呈降低趋势,其中维生素E添加水平为40 IU/kg时血浆MDA含量显著低于0 IU/kg时(P0.05);饲粮中维生素E和Se添加水平对血浆MDA含量有显著交互作用(P0.05),其中VE_(40)Se_0组的血浆MDA含量显著低于VE_0Se_(0.15)和VE_0Se_(0.30)组(P0.05)。5)随饲粮中维生素E和Se添加水平的升高,黄羽肉种鸡蛋中维生素E和Se含量显著增加(P0.05);饲粮中维生素E和Se添加水平对蛋中维生素E和Se含量有显著交互作用(P0.05)。结果提示,维生素E可以提高黄羽肉种鸡的抗氧化水平,饲粮中维生素E和Se添加水平可以显著影响蛋中维生素E和Se的含量;建议在无任何应激因素刺激和不使用Se缺乏地区饲料原料的情况下,黄羽肉种鸡玉米-豆粕型饲粮可以不用额外添加维生素E和Se。
[Abstract]:The purpose of this experiment was to study the effects of dietary vitamin E and yeast selenium on egg laying performance, hatching performance and the amount of vitamin E and selenium See in eggs of yellow feather broilers. The experiment was carried out with a 3 脳 3 double factor design with three vitamin E supplementation levels of 40 IU / kg and three se supplementation levels of 0.15 ~ 0.30 mg 路kg ~ (-1) 路min ~ (-1) 路kg ~ (-1). A total of 864 parent breeding hens were selected from 32-week-old fast Lingnan yellow broilers, which were randomly divided into nine groups according to the principle of consistency of laying rate and weight. They were respectively: VE0Se0, 0) (VE0Se0Se0), VE0Se0 (0.30), VE0Se0 (0.15), VE40Se0 (0.30), VE40Se0, and VE40Se0.30, each group, 6 duplicates in each group. Each repeats 16 chickens. The trial period was 8 weeks. The results showed that the supplementation levels of vitamin E and se in diet could increase body weight, average daily egg production, feed / egg ratio, average egg weight and laying rate of yellow feather broilers. The egg breaking rate and unqualified egg rate had no significant effect on egg length, egg short diameter, protein height, egg yolk color, hardy unit and yolk weight of yellow broilers at dietary vitamin E and se supplementation levels. The egg shell weight and egg shell thickness had no significant effect on the hatchability and shell weight of yellow broiler broilers at dietary vitamin E and se supplementation levels. The level of vitamin E supplementation in diet had a significant effect on plasma MDA content of yellow feather broiler chickens. The MDA content of plasma decreased with the increase of dietary vitamin E supplementation level. The level of vitamin E supplementation was significantly lower than that of 0 IUU / kg group (P 0.05), the dietary vitamin E and se supplementation levels had a significant interaction with plasma MDA content (P 0.05), and the plasma MDA content in VEE 40SeS 0 group was significantly lower than that in VESe 0 (0.15%) and the dietary vitamin E and se supplementation levels had a significant interaction with plasma MDA content (P < 0 05) and the dietary vitamin E and se supplementation levels had a significant interaction with plasma MDA content (P < 0 05). The vitamin E and se supplementation levels in the diet increased with the increase of vitamin E and se levels in the vitamin E and se supplementation levels. The contents of vitamin E and se in yellow feather broiler eggs increased significantly (P 0.05), and the supplementation levels of vitamin E and se in diet had a significant interaction on the contents of vitamin E and se in eggs. The results showed that vitamin E could increase the antioxidant level of yellow broiler chickens, and dietary vitamin E and se supplementation levels could significantly affect the content of vitamin E and se in eggs. It is suggested that the yellow feather broiler corn-soybean meal diet should not be supplemented with extra vitamin E and Sein without any stress stimulation and no use of feed raw materials in selenium deficient areas.
