| Fish transportation is a common practice on fish farms and is considered to be a stressor that could negatively affect fish health. The objective of this study was to evaluate several physiological responses of stress in jundiá caused by transport at different loading densities. Jundiá juveniles were placed in plastic bags on a mechanical transport simulator for four hours at four different loading densities (75, 150, 250 and 350 g L-1) and then transferred to sixteen 80-L plastic boxes for 96 hours after transport. Water samples were collected before and after transport to measure dissolved oxygen, temperature, pH and ammonia levels. Blood samples were taken at departure and arrival, as well as at 24 and 96 hours after transport to monitor cortisol,... |

| Neste estudo foi avaliado o efeito do transporte de curimbatá Prochilodus lineatus, em três densidades (100, 150 e 250 g L-1), sobre a sobrevivência e variáveis metabólicas, iônicas e hematológicas (série vermelha). Juvenis de curimbatá foram transportados em sacos plásticos durante 6h e amostrados antes da embalagem, imediatamente após a chegada, 24 e 96h após o transporte. Os peixes transportados na densidade mais alta apresentaram maior mortalidade durante o período de recuperação. As variáveis físico-químicas da água: condutividade e amônia total apresentaram maiores valores quanto maior a densidade (p < 0,05), enquanto no oxigênio dissolvido ocorreu o inverso. A glicemia observada na chegada estava elevada, reduzindo-se significativamente 96h... |

| Androgenic anabolic steroid, physical exercise and stress induce cardiovascular adaptations including increased endothelial function. The present study investigated the effects of these conditions alone and in combination on the vascular responses of male Wistar rats. Exercise was started at 8 weeks of life (60-min swimming sessions 5 days per week for 8 weeks, while carrying a 5% body-weight load). One group received nandrolone (5 mg/kg, twice per week for 8 weeks, im). Acute immobilization stress (2 h) was induced immediately before the experimental protocol. Curves for noradrenaline were obtained for thoracic aorta, with and without endothelium from sedentary and trained rats, submitted or not to stress, treated or not with nandrolone. None of the... |

| ABSTRACT The effects of vitamins E and C supplementation on growth performance and biochemical and haematological parameters of Japanese quail were studied. A total of 360 one-day-old Japanese female quails were randomly allocated to nine dietary treatment groups (10 birds per replicate and 4 replicates per treatment), including a control (basal diet) and the basal diet supplemented with: 250 or 500 mg/kg of vitamin C, 250 or 500 mg/kg of vitamin E, 250 mg/kg of both vitamins E and C, 250 and 500 mg/kg of vitamins E and C, 500 and 250 mg/kg of vitamins E and C, and 500 mg/kg of both vitamins E and C. Vitamin supplementation improved productive parameters and raised the blood plasma levels of protein, thyroid-stimulating hormone, calcium and phosphorus,... |
