| Abstract: | In order to compare the effects of mineral 2-hydroxy-4-(methylthio)-butanoic acid(HMBA) chelates(Cu,Mn,Zn) versus sulfates on laying hens,one hundred and eight 37-wk-old laying hens(Hyline Brown) were assigned to two treatments,where basal diet in the control group(CON) supplemented with a combination of inorganic minerals(sulfate source,i.e.,Cu 10 mg/kg,Zn 30 mg/kg and Mn 30 mg/kg of diet) and the treatment diets(OTM) supplemented with a combination of organic minerals to replace their inorganic forms in C... |
