Four experiments were conducted to evaluate the effects of added dietary Lcarnitine
on growth performance of nursery pigs. Pigs were fed a control diet containing no added L-carnitine or the control diet with 25, 50, 75, or 100 ppm of added L-carnitine (25, 50, or 100 ppm in Exp. 4). In Exps. 1, 2, and 3 for the overall study, ADG and F/G improved with increasing dietary L-carnitine. In Exp. 4, pigs fed increasing L-carnitine had
improved ADG from d 0 to 3 and d 10 to 24.
Increasing added carnitine improved F/G
from d 10 to 24 and for the overall study.
The results suggest that 25 to 50 ppm of
added L-carnitine can improve ADG and F/G
in nursery pigs. The largest response in pig
growth performance was found when carnitine was supplemented to the phase II diet.
