【Abstract】 Forty-two DYL ablactation piglets at 35-day-old were chosen to study the effects of three levels of dietary of L-Carnitine:0,25 mg·kg -1 and 50 mg·kg -1 on production performance.The results showed that the average daily gain(ADG)of piglets fed on the diets with 0,25 mg·kg -1 and 50 mg·kg -1 L-Carnitine were respectively 410g,425g and 465g,and F/G ration were respectively 1.58,1.56 and 1.49.The ADG of 50 mg·kg -1 L-Carnitine group was 13.41% higher(P<0.05) than the 0 L-Carnitine group,and the F/G ration was decreased by 5.70%(P<0.05).更多还原
