Abstract. The present experiment was conducted to determine the effects of dietary fermented products from chub mackerel extracts (fermented mackerel extracts) on growth, carcass composition, contents of various lipid fractions in the liver, the serum, and the thigh muscle, and activities of lipogenic-related enzymes in the liver of broilers. Fermented mackerel extracts supplementation resulted ini an insignificant slight increase in final body weights of broilers. Fermented mackerel extract did not affect liver weights, but abdominal fat weights of female broilers were significantly decreased by the addition of 2.0% fermented mackerel extracts. Lipid fraction contents of the serum and the liver of broilers were unaffected by fermented mackerel extracts. Triglyceride and free cholesterol contents of the thigh muscle of broilers were significantly decreased or tended to be decreased by adding 1.0 or 2.0% fermented mackerel extracts. Activities of acetyl-CoA carboxylase and faftty acid synthetase in the liver were not affected by dietary feremented mackerel extracts. However, activities of malic enzyme, citrate cleavage enzyme and HMG-CoA reductase in the liver were significantly decreased by 1.0 or 2.0% fertmented mackerel extracts. Dietary fermented mackerel extracts tended to decrease the proportion of crude fat and to increase that of moisture in broiler carcasses (Anim. Sci. Technol. (Jpn), 63 (1): 32-37, 1992
Key words: chub mackerel extracts, broilers, hepatic lipogenesis, carcass composition, abdominal fat
