“…An increment in diet protein produces a rise in the synthesis of cholesterol in the liver and intestines but a reduction in plasma concentration, while a lowprotein diet causes a high plasma cholesterol level, reducing its excretion (Leveille and Sauberlich 1961;Yeh and Leveille 1972;Lewandowski et al 1986). Cholesterol contributes to the intestinal absorption of nutrients because it is part of biliar acids and takes part in the construction of cell membranes, especially during growth (Griminger 1986). In this way, the cholesterol decline shown here could suggest a decline in anabolic processes.…”

ABSTRACTAn investigation of the effects of fasting, subfeeding, and refeeding on plasma biochemistry was carried out on 22 captive yellow-legged gulls Larus cachinnans Pallas. These birds showed the same fasting endurance model described in other species, but with an important decrease in glucose plasma concentration and very great differences between individuals when reaching the deterioration limit, suggesting a moderate physiological adaptation to long periods of fasting. A different model was proposed in subfed gulls in relation to fasted gulls, based on lipid and protein use, which could be reflected by changes in nitrogen wastes and triglyceride levels in this experiment. Thus, the subfed gulls might use protein directly from the diet as an energy source, thereby reducing the use of fat stores. The gulls quickly recovered body mass during the refeeding period, but while some plasma substances quickly reached their initial values, others showed many changes before the end of the experiment, which could reflect a process of metabolic restabilization. These results contribute to a better knowledge of fasting, subfeeding, and refeeding processes in birds and can be added to a recent study about fasting in gulls.

“…However, our triglyceride concentration analyses included amounts of free glycerol. Triglycerides are the precursors of glycerol, free fatty acids, and, finally, ketone bodies such as b-hydroxybutirate (Griminger 1986). Therefore, the observed increment can reflect the fat reserve mobilization.…”

“…. In addition to that, butyrate produces mucin glycoproteins in the intestinal epithelium and increase the defence barrier of colon mucosa (Leonel and Alvarez-Leite, 2012).Butyrate increases serum globulin concentrations and lowers albumin to globulin ratio (Griminger, 1986).Studies showed that, BAG at 0.4 % in broiler ration increased serum total protein, albumin and globulin (Ali et al, 2014) in normal and Eimeria maxima challenged-birds.SB at 0.1 % in broiler ration had no influence of serum total protein in healthy birds but in E.coli LPS challenged birds BA prevented the elevation of the serum total protein (Zhang et al, 2011a).Unlike the above results, BAG supplementation at 0.3 (Mahdavi and Torki, 2009) and BA at 3.0 % (Kamal and Ragaa, 2014) did not influence serum total protein, but in the latter study, serum globulin level was significantly higher.…”

“…A/G ratio has been used as an indicator of immune responses so that high globulin level and low A/G ratio signify better disease resistance and immune responses (Griminger, 1986). In addition, the reliability of H/L Ratio as a biological index of stress in avian species is also, well documented (Maxwell, 1993).…”

This study was conducted to determine the impacts of two levels of oyster mushroom (Pleurotus ostreatus) powder on productive and carcass traits, humoral immune responses, and blood characteristics of Ross 308 male broiler chicks reared to 42 d of age in comparison with a prebiotic supplement. Two hundred and forty, day-old male broiler chicks (Ross 308) were randomly assigned to one of four treatments with four replicates of 15 chicks based on a completely randomized design. The dietary treatments consisted of the basal diet as control, prebiotic group receiving 1 g/kg A-Max ® (Mannan-oligosaccharides), 10, and 20 g/kg oyster mushroom powder added to the basal diet. The obtained results showed that inclusion of 20 g/kg mushroom powder significantly improved body weight over the starter and grower (P＜0.05) while feed efficiency was improved only over the starter (P＜0.05) period compared to the control group. Considering the entire experimental period, (1-42 d) birds receiving prebiotic supplemented diets exhibited the highest body weight and lowest feed conversion ratio relative to the other treatments (P＜0.05). Carcass yield and internal organs relative weights were not influenced by dietary treatments, but prebiotic supplementation significantly (P＜0.05) decreased abdominal fat pad compared to the control group. Newcastle, influenza and sheep red blood cell antibody responses of chicks did not differ significantly at either level of inclusion of supplements. Chicks fed supplemented diets had the lowest serum triglyceride concentration at 42 day (P＜0.05) compared to the control chicks, but other biochemical and hematological values tested including protein, albumin, globulin, high-density lipoprotein, low-density lipoprotein, and total cholesterol, red blood cell, white blood cell, hemoglobin and hematocrit were not markedly affected by treatments. In conclusion the obtained results indicated that oyster mushroom powder at an inclusion level of 20 g/kg of diet had favorable effects on performance criteria of chicks reared to 28 day of age while, prebiotic supplementation revealed its beneficial impact on chicks productive traits at slaughter age, besides reducing carcass abdominal fat and serum triglyceride concentration at 42 day.
