硒锌铜交互效应对肉鸡胸肌铜、锌、铁、锰、钙含量的影响

研究了日粮不同硒、锌和铜水平及互作效应对肉鸡胸肌中铜、锌、铁、钙、锰含量的影响.选用1日龄罗斯308肉仔鸡720只,随机分为9个处理组.在玉米-豆粕型日粮基础上添加不同水平的蛋氨酸硒、甘氨酸锌和甘氨酸铜,以饲喂基础日粮组为对照组,试验期7周.结果表明:1)日粮不同硒水平对前中期胸肌铜含量的影响显著,对中期胸肌锌含量影响极显著,对后期胸肌铁含量影响显著,对前中后期胸肌钙含量影响不显著,对前期胸肌锰含量影响显著;2)日粮不同锌水平对前中后期胸肌铜含量影响显著,对中期胸肌锌含量影响极显著,对中期胸肌铁含量影响显著,对前期胸肌锰含量影响显著,对前中后期胸肌钙含量影响不显著;3)日粮不同铜水平对前中期胸肌铜、锌含量的影响显著,对后期胸肌锰含量影响显著,对前中后期胸肌铁、钙含量影响不显著;4)硒、锌和铜的交互作用对前中后期胸肌铜、锌、锰含量影响显著,特别是中期胸肌铜、锌含量影响极显著,对中后期胸肌铁含量影响显著,对中期胸肌钙含量影响显著.

Interactive effect of organic Se,organic Zn and organic Cu on the concentration of Cu,Zn,Fe,Mn and Ca in breast muscles in broilers

In order to study the interactive effect of additive of Se/Zn/Cu on the concentration of copper,zinc,iron,manganese and calcium in breast muscles in broilers,the experiment was conducted using a total of 720 four-week-old Rose 308 broilers to investigate the effects of adding methionine-Se,Glycine-Zn and Glycine-Cu to corn soybean diets on growth and slaughter performance in broilers and their interaction.Broilers were randomly divided into 9 treatments.The basal diet was used as control group,and the exper...
