Carnitine prolongs the half-life of ethanol in broilers

The object was to determine if carnitine attenuated ethanol metabolism in broilers similar to that reported in the rats. Two groups (n = 5) of 5-week-old broilers were given for 10 days the feed with or without 0.5% L-carnitine supplement. A single oral dose of ethanol on day 8 was followed by serial blood samples which were analysed for ethanol. Another dose of ethanol was given on day 10 and 2 hr later, plasma and liver were collected and analysed for ethanol, total lipid, triglycerides and carnitine. The carnitine supplemented diet prolonged the half-life of ethanol due to attenuation of ethanol metabolism which is similar to that reported earlier in rodents. The increases in plasma and hepatic acylcarnitines indicate that supplementary carnitine lessens the load of free acyl groups in the liver by eventual oxidation or excretion.
