The objective was to evaluate the differences between distinct types of litter material and their combinations in the dynamics of degradation on the organic matter fractions and the quality of the final compound. The treatments were established according to material used as substrate for broiler litter: treatment 1 – rice husks; 2 – sugar cane bagasse; 3 – wood shavings; 4 – wood shavings + sugar cane bagasse; 5 – rice husks + sugar cane bagasse; and 6 – Napier […]

The objective of this study was to establish a correlation between the content of total lipids, cholesterol and fatty acid profile of the edible portion of the shoulders of 12 castrated and 12 non-castrated Santa Ines lambs, slaughtered at different ages (84, 168, 210, 252 days). Shoulders and the edible portion (muscle and fat) were weighed and stored at -5 °C. Castrated and uncastrated lambs increased their body weight and half carcass weight, respectively. The shoulder weight increased in the […]

This study was developed with the objective of evaluating reflective paint on covering and artificial ventilation on performance of broilers (males and females). A randomized design with a 2 × 2 × 2 factorial arrangement of treatments was used, as follows: 2 external management systems (coverage with and without reflective paint), 2 internal management systems (with and without artificial ventilation) and 2 sexes (male and female), totalizing 8 treatments. A total of 480 1-day old chicks of the Cobb strain […]

The objective of this study was to identify possible alterations in the composition and anaerobic biodigestion process of manure from Canchim and Nellore cattle in different periods in feedlot fed with different forage to concentrate ratios. The experiment was carried out in complete randomized design in factorial arrangement with time as sub-divided plot. Plots were established by four treatments: manure from two diets (40% forage and 60% concentrate and 60% forage and 40% concentrate) and two genotypes (Canchim and Nellore) […]

This study was designed to investigate the effect of early weaning and concentrate supplementation on performance and metabolic profile of lambs in four production systems on pasture: suckling lambs not supplemented until slaughter; suckling lambs supplemented with concentrate in creep feeding until slaughter; early weaned lambs not supplemented until slaughter; early weaned lambs supplemented with concentrate until slaughter. Performance was assessed by average daily gain (ADG) and body condition score (BCS) measurements. Metabolic profile was delineated by measuring serum albumin, […]

The objective of this study was to identify possible alterations in composition and in the composting process of manure produced by Canchim and Nellore cattle in different periods of feedlot and fed different forage to concentrate ratios. The experiment was carried out in complete randomized design in factorial scheme with time as subdivided plot. Plots were established by four treatments: manure from two diets (40% forage and 60% concentrate and 60% forage and 40% concentrate) and two genotypes (Canchim and […]

The present study was conducted to assess carcass features, physicochemical and sensory parameters of meat from steers finished on three types of pastures: natural pasture; natural pasture improved, fertilized and oversown with winter species; and annual summer grassland. The experiment was conducted from December 14, 2009 to November 30, 2010, with treatments distributed in a completely randomized design with a different number of replicates. Animals were used as experimental units. Experimental animals were Aberdeen Angus steers with twenty months of […]

The objective of this study to assess the relationship between ewe maternal behavior score and physiological parameters related to their temperament. During lambing, 258 Corriedale and 50 Polwarth ewes were evaluated. They were raised on native pasture in the southwest region of Rio Grande do Sul State, Brazil. The effects of farm, age, type of lambing, maternal behavior scores and body condition score before lambing and during the weaning were evaluated in relation to heart rate, respiratory rate and body […]

The objective of this experiment was to study the behavior of chicken consumer, with emphasis on animal welfare and on the willingness to pay a higher value for products with certification for this attribute of quality. Thus, a market research was conducted with consumers of broiler meat in the city of Curitiba, Paraná. A primary analysis was done with experts of the avian chain. After this, 481 consumers were interviewed. Straight questions generated general information and images of the hypothetical […]

The objective was to evaluate the performance of beef heifers until calving receiving different levels of supplementation on native pasture during the first breeding season, from 14 to 17 months: no supplementation; 3.5 g/kg of body weight; and 7.0 g/kg of body weight. Ninety-eight Charolais, Nellore and their crosses, with average initial weight of 255 kg, were used. Weight at the end and average daily weight gain during the supplementation period were higher for 7.0 g/kg of supplement heifers (322 […]
