| Popis: | The effects of CP and antioxidants on fatty liver hemorrhagic syndrome (FLHS) in Japanese quail hens were studied. In Experiment 1, four treatments were arranged as a 2 × 2 factorial; dietary CP (18 or 24%) and reduced glutathione (GSH, 0 or 120 mg/kg diet) were the major variables, but cysteine and other amino acids were higher in the 24% CP diets. Negative control (NC1) and positive control (PC1) diets were also evaluated. In Experiment 2, the effects of vitamin E (VE) and GSH were evaluated in the presence and absence of adequate dietary sulfur amino acids. Negative control (NC2) and positive control (PC2) diets were used. In both experiments, liver hemorrhage was most severe in quail fed the diets that were formulated to induce hepatic steatosis and limit oxidant defense capability. Liver hemorrhage was least severe in quail fed the diets that were formulated to minimize liver lipid accumulation and support oxidant defenses. Histological evaluation of affected quail livers showed changes consistent with FLHS in chicken hens. In Experiment 1, neither CP concentration nor GSH supplementation influenced liver hemorrhage. In Experiment 2, liver hemorrhagic score was reduced from 3.8 to 2.7 (P ≤ .05) by adding VE to the basal diet The PC2 diet further depressed liver score to only 2.0 (P ≤ .05). The data clearly show that Japanese quail are susceptible to FLHS and indicate that a combination of lipotropic and antioxidant nutrients is protective against hemorrhage, even when lipogenic demands are maximized by feeding diets devoid of added fat. |
