  • Carnitine supplemented finishing pig diet
    Patent number: 5124357
    Abstract: Feed compositions containing at least 0.6% lysine, preferably between about 0.7 and 0.8% lysine, and between approximately 0.1 to 400 ppm, preferably between 5 and 50 ppm, L-carnitine produce greater weight gains and feed efficiency, and alter fat metabolism, as compared with the same diet in the absence of the carnitine when fed to the finishing pigs. The L-carnitine can also be administered as a feed supplement providing between 0.05 and 15 mg L-carnitine/kg body weight/day, most preferably between 0.1 and 2.0 mg L-carnitine/kg body weight/day. The effect of the carnitine is sex linked, with significantly greater weight gains and feed efficiency observed for gilts than for barrows.
