Effects of L-carnitine in the gestating sow diet on fetal muscle development and carcass characteristics of the offspring. J. Appl. Anim. Res., 31: 105–111. A total of 232 sows were used to determine the effects none or an additional 50 ppm of L-carnitine in the gestation diet on sow and offspring performance. Sows were fed dietary treatments from breeding until d 110 of gestation. Offspring from sows were ear-notched according to maternal treatment at birth and carcass data were obtained at slaughter. Sow plasma IGF-I concentration was similar (P>0.10) between control and L-carnitine supplemented sows on d 30 and 60 of gestation at 2 h after feeding. No differences were observed in either the immediate or subsequent number of pigs born per litter. No differences were observed in a sub-sample (n = 181) of pig weight at birth, weaning or d 59 of age between control and treatment offspring. Anal... |
