Effect of dietary fish oil on the nutrient metabolism and anti-oxidant enzyme activity during the acute phase response in broiler chicks

Koh T.S., . and J.T.I, . and Lee S.I., . (2004) Effect of dietary fish oil on the nutrient metabolism and anti-oxidant enzyme activity during the acute phase response in broiler chicks. [Proceedings Paper]

An anti-oxidant enzyme activities and metabolism of protein and energy was studies to evaluate the effects of dietary n-3 fatty acids with on the lessening of growth-suppressive effects during the acute phase response. One-day old chicks were fed on a diet containing 1.0 of either soybean oil basal diet:SO or fish oil FO and the acute phase response activated injecting with Salmonella typhymurim lipopolysaccaride LPS during 2nd week of age. During the acute phase response dietary fish oil lessened growth-suppressing effect of the LPS-effect and lowered p0.05 the activities of manganese superoxide dismutase MnSOD and copper/zinc SOD CuZnSOD and ceruloplasmin in liver sytosol. And the acute phase response did not affect the excretion of uric acid nitrogen per nitrogen intake nitrogen balance while increased P0.05 ME value of diet. The highered ME value of the fish oil diet was due to enhanced digestive absorption of dietary energy sources and linked with the lowered activity of SOD in liver and ceruloplasmin in plasma. The results indicated that dietary fish oil alter energy metabolism accompanied with a change on the antioxidants systems during the acute phase response.

Abstract

An anti-oxidant enzyme activities and metabolism of protein and energy was studies to evaluate the effects of dietary n-3 fatty acids with on the lessening of growth-suppressive effects during the acute phase response. One-day old chicks were fed on a diet containing 1.0 of either soybean oil basal diet:SO or fish oil FO and the acute phase response activated injecting with Salmonella typhymurim lipopolysaccaride LPS during 2nd week of age. During the acute phase response dietary fish oil lessened growth-suppressing effect of the LPS-effect and lowered p0.05 the activities of manganese superoxide dismutase MnSOD and copper/zinc SOD CuZnSOD and ceruloplasmin in liver sytosol. And the acute phase response did not affect the excretion of uric acid nitrogen per nitrogen intake nitrogen balance while increased P0.05 ME value of diet. The highered ME value of the fish oil diet was due to enhanced digestive absorption of dietary energy sources and linked with the lowered activity of SOD in liver and ceruloplasmin in plasma. The results indicated that dietary fish oil alter energy metabolism accompanied with a change on the antioxidants systems during the acute phase response.
