Carnitine prolongs the half-life of ethanol in broilers

Area of Science:

• Animal Science
• Biochemistry
• Nutritional Science

Background:

• Ethanol metabolism is a critical process influenced by nutritional factors.
• Carnitine plays a vital role in lipid metabolism and energy production.
• Previous studies suggested carnitine's influence on ethanol metabolism in rodents.

Purpose of the Study:

• To investigate the effect of L-carnitine on ethanol metabolism in broiler chickens.
• To determine if L-carnitine attenuates ethanol metabolism similarly to findings in rats.
• To assess the impact of L-carnitine on plasma and liver parameters related to ethanol and lipid metabolism.

Main Methods:

• Two groups of 5-week-old broilers (n=5 per group) were fed diets with or without 0.5% L-carnitine for 10 days.
• A single oral dose of ethanol was administered on day 8, with serial blood sampling for ethanol analysis.
• On day 10, ethanol was administered again, followed by plasma and liver collection for analysis of ethanol, total lipid, triglycerides, and carnitine.

Main Results:

• L-carnitine supplementation significantly prolonged the half-life of ethanol in broilers.
• Ethanol metabolism was attenuated in the L-carnitine supplemented group compared to the control.
• Increased plasma and hepatic acylcarnitines were observed, suggesting reduced free acyl groups in the liver.

Conclusions:

• Dietary L-carnitine attenuates ethanol metabolism in broiler chickens, mirroring effects seen in rodents.
• Supplementary carnitine appears to mitigate the hepatic load of acyl groups, facilitating their oxidation or excretion.
• L-carnitine holds potential for modulating ethanol's metabolic impact in poultry.
