【摘要】：本試驗旨在研究飼糧不同硒添加水平對1~21日齡嶺南黃羽肉仔雞生長性能和抗氧化性能的影響,以探討快大型嶺南黃羽肉仔雞飼養(yǎng)前期的飼糧硒適宜供給量。選用1日齡健康、發(fā)育良好的快大型嶺南黃羽肉公雛雞1 200只,根據(jù)體重隨機分為5個組,每組6個重復(fù),每個重復(fù)40只雞,試驗1組(對照組)飼喂基礎(chǔ)飼糧(硒水平為0.039 mg/kg),試驗2~5組飼糧在基礎(chǔ)飼糧中分別添加0.075、0.150、0.225和0.300 mg/kg硒,試驗期21 d。結(jié)果表明:本試驗條件下:1)與對照組相比,飼糧添加0.300 mg/kg硒顯著降低1~21日齡嶺南黃羽肉仔雞的末重(P0.05),顯著提高料重比(P0.05),且0.300 mg/kg硒添加組的平均日增重顯著低于其他各水平硒添加組(P0.05)。2)與對照組相比,飼糧添加0.075和0.150 mg/kg硒顯著提高21日齡嶺南黃羽肉仔雞的血漿谷胱甘肽過氧化物酶(GSH-Px)活性(P0.05),飼糧添加0.225和0.300 mg/kg硒顯著降低血漿丙二醛(MDA)含量(P0.05)。各水平硒添加組的紅細胞GSH-Px活性均顯著高于對照組(P0.05)。3)與對照組相比,飼糧添加0.075、0.150和0.225mg/kg硒顯著提高21日齡嶺南黃羽肉仔雞的肝臟GSH-Px活性(P0.05),0.075和0.150 mg/kg硒添加組的肝臟MDA含量顯著低于對照組和0.300 mg/kg硒添加組(P0.05)。綜合考慮,為獲得較好生長性能和抗氧化性能,1~21日齡嶺南黃羽肉仔雞飼糧硒適宜添加水平為0.075 mg/kg,基礎(chǔ)飼糧中硒水平為0.039 mg/kg,則1~21日齡嶺南黃羽肉仔雞飼糧硒適宜供給量為0.114 mg/kg;以肝臟MDA含量為依據(jù),通過非線性回歸分析估測得到1~21日齡嶺南黃羽肉仔雞飼糧硒適宜供給量為0.130 mg/kg。
[Abstract]:The purpose of this study was to study the effects of different dietary selenium levels on growth performance and antioxidant activity of 1-day-old Lingnan yellow feather broilers, and to explore the appropriate dietary selenium supply for fast and large Lingnan yellow feather broilers in the early stage of feeding. 1 200 fast large Lingnan yellow feather male chicks, healthy and well developed, were randomly divided into 5 groups according to their body weight, 6 replicates in each group and 40 chickens in each replica. Group 1 (control group) was fed with basic diet (selenium level was 0.039 mg/kg). In experiment 2, the diets of group 2 were supplemented with 0. 075 (0.150) and 0.300 mg/kg selenium, respectively, for 21 days. The results showed that the ratio of 1 to 1 in this experiment was higher than that in the control group. Dietary supplementation of 0.300 mg/kg selenium significantly decreased the end weight of Lingnan yellow feather broiler (P0.05), significantly increased the feed weight ratio (P0.05), and the average daily gain of the 0.300 mg/kg selenium added group was significantly lower than that of the other levels of selenium addition group (P0.05) compared with the control group. Dietary selenium of 0.075 and 0.150 mg/kg significantly increased plasma glutathione peroxidase (GSH-Px) activity of 21-day-old Lingnan yellow broilers (P0.05), and dietary supplementation of 0.225 and 0.300 mg/kg selenium significantly decreased plasma malondialdehyde (MDA) content (P0.05). The erythrocyte GSH-Px activity of selenium added group was significantly higher than that of control group (P0.05). The liver GSH-Px activity of 21-day-old Lingnan yellow feather broilers was significantly increased by dietary supplementation of 0.075 and 0.150 and 0.225mg/kg selenium (P0.05). The content of MDA in liver of the groups supplemented with 0.075 and 0.150 mg/kg se was significantly lower than that of the control group and 0.300 mg/kg se added group (P0.05). Taking into account, In order to obtain better growth performance and antioxidant activity, the optimum dietary selenium supplementation level was 0.075 mg/kg, for Lingnan Yellow Feather broiler, and 0.039 mg/kg, for Lingnan Yellow Feather broiler at 1 ~ 21 days of age, while 0.114 mg/kg; for Lingnan Yellow Feather broiler at 1 ~ 21 days. Based on the content of MDA in liver, The optimum dietary selenium supply of Lingnan yellow feather broiler was estimated to be 0.130 mg/kg. by nonlinear regression analysis.
