Varied sources and levels of zinc in Ross 308 broiler rations: Its effect on performance, nutrient utilization, intestinal morphology and microbial composition

Varied sources and levels of zinc in Ross 308 broiler rations: Its effect on performance, nutrient utilization, intestinal morphology and microbial composition

ABSTRACT Broilers (n=480) were used in an experiment designated for a 3(4 factorial arrangement to investigate the efficacy of three zinc (Zn) sources (organic Zn-Methionine, inorganic Zn sulphate and Zn oxide) and four inclusion rates (zero, 60, 120 and 180mg/kg of feed). Growth performance was not...

Zusammenfassung:ABSTRACT Broilers (n=480) were used in an experiment designated for a 3(4 factorial arrangement to investigate the efficacy of three zinc (Zn) sources (organic Zn-Methionine, inorganic Zn sulphate and Zn oxide) and four inclusion rates (zero, 60, 120 and 180mg/kg of feed). Growth performance was not affect by Zn source in the entire of experimental period, however Zn level at 180 mg/kg improved body weight gain and feed conversion ratio compared to other Zn levels (P
