The objective of this work was to evaluate nutritional characteristics of meat from lambs finished on feedlot with diets containing sugar cane or corn silage on two roughage:concentrate ratios (60:40 or 40:60). It was used 32 non castrated Ile de France lambs, with 15 kg of body weight distributed in a complete random experimental design in a 2 × 2 factorial arrangement. The animals were confined in individual stalls and slaughtered at 32 kg. Lamb meats had 74.55% of moisture, […]

The objective was to evaluate the physical, chemical and sensory of buffaloes meat slaughtered in different periods of feedlot. Twenty castrated, hornless Murrah buffaloes with initial average age of 15 months old were slaughtered at 75, 100, 125 or 150 days of feedlot. After slaughter, the carcasses were identified and cooled for 24 hours. During the deboning, samples were taken from striploin between the 10th and 11st ribs for sensory characteristics analyses and cooking losses; between 11st and 12nd ribs […]

The aim of this work was to determine the centesimal composition and fatty acids profile of freshwater prawn (Macrobrachium amazonicum) for determination of its nutrient potential. Six lots (each one with 100 g) containing whole prawns with individual mass ranging from 0.9 to 1.2 g were triturated and stored for posterior chemical analysis. The average values for moisture, ash, CP and total lipids were as follows: 70.3, 1.5, 24.8, and 1.5%, respectively. It was detected 36 varieties of fatty acids, […]

The objective of this study was to evaluate the meat centesimal composition of Santa Ines pure breed and Santa Ines vs Texel crossbreed lambs, slaughtered at different body weights. Thirteen males and fourteen females from both breeds were selected. The muscle biceps femoris was used to determine water, crude protein, crude extract and minerals contents. The experiment was arranged randomly, with 16 traits in a 2x2x4 factorial scheme with two genetic groups, two genders (14 males and 13 females in […]
