| Outline of Final Research Achievements |
Fatty liver is incidentally induced in chicken, which is much-prized delicacy. We investigated the effect of nutritional manipulation on lipid content in the liver of culled layer-chicken.
Low methionine and low choline diet did not affect free methionine and choline concentrations in plasma, and hepatic lipid content, suggesting that the low methionine and low choline diet did not induce methionine and choline shortage in culled layer-chicken. High fructose diet did not affect hepatic lipid content. However, this diet increased mannitol content in the liver, suggesting that intestinal microbes produce mannitol from fructose and the absorbed mannitol accumulates in the liver. Because severe inflammation is frequently observed in the liver, we also investigated the effect of vitamin E supplementation on the induction of hepatic inflammation. However, vitamin E supplementation did not affect hepatic inflammation.
