Combination of betaine and some other methyl donor compounds to improve growth performance, lipid metabolism, and liver function of broilers [electronic resource].

Includes references.

The effect of betaine, Dl-methionine, and choline on the growth performance. lipid profile, liver function, lipid peroxidation, and carcass characteristics of broilers was examined. A total number of 240 broiler chicks were divided into four different groups (control and three groups treated with 1g betaine, 0.5g betaine + 0.5 g DL Methionine or 0.33g betaine + 0.33 g DL- Methionin +0.33 g choline / liter via drinking water). The results indicate that weight gain of broilers treated with betaine is significantly higher than control while combination of betaine by methionine or choline did not cause any significant deference in body weight gain. Also, the methyl donor compounds significantly reduced the percentage of abdominal fat in carcass. Treatment with betaine or mixture of betaine and methionine and choline led to significant reduction in total lipids, triglycerides, and LDL cholesterol.
