The proton conductance of isolated liver mitochondria correlates significantly with body mass in mammals, but not in ectotherms. To establish whether the correlation in mammals is general for endotherms or mammal-specific, we measured proton conductance in mitochondria from birds, the other main group of endotherms, using birds varying in mass over a wide range (nearly 3000-fold), from 13 g zeb...

The present study examined the antioxidant defense of glutamine on plasma and liver antioxidant status in broilers under PHS with respect to changes in the levels of lipid peroxidation marker malondialdehyde (MDA), total antioxidant status (TAS) and the activities of anti peroxidative enzymes [superoxide dismutase (SOD) and glutathione dependent antioxidant enzymes glutathione peroxidase (GPX)]...

PURPOSE Red ginseng (RG) has been reported to improve the blood and organ lipid profile when combined with exercise. However, the effect of RG on energy metabolism during exercise is poorly understood. Therefore, this study was designed to investigate whether RG treatment alters fat utilization during exercise; METHODS We used seven-week-old ICR mice (n = 42). RG (1 g/kg) was administered ora...

This study examined the effects of various levels of dietary encapsulated choline chloride (ECC) on growth performance, carcass characteristics, serum and liver lipids content in Ross 308 broilers. A total of 480 day-old broilers were assigned to eight dietary treatments with six replicates of 10 birds each from 1 to 21 days of age. Eight experimental diets were provided from a basal non-added ...

The potential of feeding a blend of 3 strains of Bacillus subtilis (Sporulin; SPR), to control Salmonella (SAL) was evaluated in broilers challenged with a strain of Salmonella Heidelberg (SH) isolated in Brazil . A total of 288 broilers were allocated to 6 treatments of 4 replicates of 12 birds each . Groups were T1) Non-challenged (NC), T2) NC fed 250 g of SPR/ton, T3) NC fed 500 g of SPR/ton...

The present experiment was conducted to investigate the effect of drinking water temperature and stocking density (SD) on oxidative metabolism in heart, liver, bursa fabricius, thymus broiler chickens raised under heat stress. comprised 360 one-day-old Ross 308 male randomly divided 6 experimental groups with 4 replicates each group. Experimental treatments included three different SD (low = 12...

AIM The present investigation was conducted to isolate and characterize Salmonella Gallinarum from an outbreak of fowl typhoid in layer birds. MATERIALS AND METHODS Clinically ill and dead layer birds from an outbreak were investigated. History, clinical signs, and postmortem lesions were suggestive of fowl typhoid. Postmortem samples including heart blood, intestinal contents, pieces of ovar...

This experiment was conducted to evaluate the ability of Silybum marianum seeds (SMS) on performance, carcass variables, and liver morphology of the broiler chickens contaminated with aflatoxin B1 (AFB1). A total of 216 broiler chicks (Ross 308) were used. Birds were randomly assigned to nine treatment groups, with four replicates and six birds in each replicate. Chickens were reared on litter ...

Clinical, pathological, and epidemiological findings are presented on fatty liver syndrome mainly in houbara bustards (Chlamydotis undulata macqueenii), but also in some other bustard species. Of 72 houbara bustards, 34 (47%) had fatty liver diagnosed post-mortem. Males and females were equally susceptible, and both adults and juvenile birds were affected. Bustards with fatty liver had signific...

Marek’s disease (MD) was observed in Japanese quails. Gross lesions were confined mostly to the proventriculus, spleen and liver. Microscopic lesions were commonly seen in the spleen and liver. Suggestive lesions of MD were observed in seven out of 20 birds grossly. Organs were collected from all the 20 necropsied birds. The birds which were not revealing gross lesions were also tested for MD v...
