| This review aimed to identify the importance of vitamin E dietary supplementation to broilers subjected to heat stress in relation to metabolism, growth performance and quality of animal products and its effects on immune system. Vitamin E is the concentration of tocopherol and tocotrienol, which can be found in natural or synthetic form. This vitamin is essential for the integrity of reproductive, muscular, circulatory, nervous and immune systems of the animals. In order to reduce the harmful effects of high temperatures in poultry production, vitamin E supplementation is a viable alternative for the sector. Some studies indicate its potential antioxidant effect able to modulate inflammatory responses and physiological adjustments to mitigate the... |

| ABSTRACT The objective this paper was to evaluate the effect of two categories of beef finished in pasture with supplementation with two herbage allowance on performance, carcass and meat characteristics. Thirty-six Guzera cattle were used, 18 steers and 18 heifers with an initial age of 20 months. There was significant difference in daily weight gain for animal category and the herbage allowance, which were higher in males and animals submitted to high herbage allowance. Steers showed higher final weight, carcass weight and forequarter yield compared with the heifers, although the hindquarter yield was higher in the heifers, however the herbage allowance did not influence these characteristics. There were not statistical differences for carcass yield,... |

| The aim of this study was to evaluate the effect of increasing levels of concentrate on the quantitative and qualitative carcass characteristics of feedlot ewes. Twenty-four crossbred ewes were randomly distributed in four treatments: (1) diet with 20%; (2) 40%; (3) 60%; and (4) 80% of concentrate. Animals were slaughtered when those receiving the diet with 80% of concentrate reached adult weight, at around 50kg LW. The data were analyzed by means of variance and regression analyses and correlations. The levels of concentrate increased live weight at slaughter linearly. Height at the withers and rump presented medium to high correlation (0.86). The correlation of loin eye area measured on the carcass and by ultrasound examination was 0.81, whereas for back... |

| Nowadays, consumers are demanding more natural foods, obliging the industry to include natural antioxidants in foods. Natural antioxidants have been used instead of synthetic antioxidants to retard lipid oxidation in foods to improve their quality and nutritional value. This review discusses some aspects of recent research on antioxidant activity of plant extracts and natural compounds to improve meat quality. Many herbs, spices, and their extracts have been reported as having high antioxidant capacity, such as some plants of the Lamiaceae family, e.g., oregano (Origanum vulgare L.), rosemary (Rosmarinus officinalis L.), and sage (Salvia officinalis L.). The antioxidant activity of these plants is attributed to their phenolic compound content, which... |

| The objective of this study was to evaluate the physicochemical and microbiological parameters of pork meat submitted to dry salting. Sodium chloride (NaCl) was added at levels of 0%, 2.5%, 5%, 7.5% or 10% by the meat weight. Dry salting technique was used, which consists of rubbing the sodium chloride manually, followed by a rest period. The data were submitted to analysis of variance using a completely randomized experimental design. The means were compared by Duncan test at 5%. The salting process reduced (P < 0.05) humidity and water activity, and it increased (P < 0.05) ash, chloride, palmitic acid, and water holding capacity levels compared to those of the control. Luminosity (L*) was lower (P < 0.05) in the control, and a* color was more... |

| Abstract The aim of the present study was to compare the proximate analysis and fatty acid profile of water buffalo meats. Samples were taken from three different local meat suppliers in Baklalı, Orcunlu, and Nakkas villages, Istanbul Province, Turkey. Animals were males 24 months old reaching final live weights of 420-440 kg. Significant differences were observed in pH, moisture, fat, color and fatty acid profile of water buffalo meats (p<0.05 and p<0.01). The results of proximate analysis demonstrated that the pH (5.03-5.46), moisture (48.60-59.73%), fat (18.90-30.02%), ash (2.48-3.56%), protein (15.12-17.65%), ‘L’ lightness (24.38-33.50), ‘a’ redness (9.88-13.81), and ‘b’ yellowness (5.66-8.53) were found in the samples.
