Abstract
A trial was conducted to evaluate the effects of copper amino acids complex in piglet diet. 288 (Duroc x Landrace x Yorkshire) hybrid piglets weaned at 23 d with body weight 8.79±1.15 kg were selected and allotted to one of the 6 treatments.Results showed that: 1) The addition of AV Cu or CuSO4 will not affect the daily average yield (ADFI) of weaned piglets, but the dietary AV Cu will linearly increase the daily gain (ADG) of weaned piglets and reduce the feed gain (FGR); the 90-100 mg/kg copper of AV Cu is equivalent to the 150 mg/kg copper of CusO4 on the ADG and FCR.; 2) Av-Cu inclusion in diet decreased diarrhea incidence of piglets.Base on this experiments, supplementation of Av-Cu into weaning piglet diet reduced diarrhea incidence, promoted growth and facilitated feed conversion of weaning piglets, as well as altered blood biochemistry indices.
