| Current study evaluated the effect of different sexual groups and different concentrate levels in diets on animal performance, feed efficiency and carcass characteristics of bovines finished in feedlot. Ninety four bulls and 75 steers Purunã with average age 19 months at the beginning of the feedlot period were used. Animals were maintained in individual pens during 116 days and fed with a diet of corn silage and three concentrate levels (0.8, 1.1, and 1.4% of body weight). The concentrate was formulated with 25% soybean meal, 73% corn grain, 1.0% of a mineral mix and 1.0% limestone and adjusted at every 28 days. The interaction between sexual groups and concentrate levels was not significant for any of the studied variables. Bulls were more efficient than... |

| This study was realized to evaluate the production and economic viability of finished beef cattle in feedlot in the Cerrado biome of Piauí State, Brazil. One hundred and fifty cattle -50 bulls (B) with an body weight of 283.0 ± 20.82 kg, at 30 months of age; and 100 cull cows (CC) with an body weight of 296.1 ± 17.80 kg, at 100 months of age- were used in a completely randomized design. The animal performance indicators for the evaluation of economic viability were initial age (months), slaughter age (months), was initial body weight (kg), final body weight (kg), daily feed intake (kg animal-1; kg kg-1 BW), diet cost (R$ kg-1 of diet), cost of kg produced (R$ kg-1 produced), and average price of the kg of meat for finishing (R$). The CC consumed more... |

| The influence of the replacement of soybean meal by crambe crushed in concentrated supplement at proportions 0, 5, 10, 15%, on the performance and carcass traits of grazing cows is assessed. Within a completely randomized design, twenty Nellore cows, fed on Brachiaria humidicola, were supplemented during the rain-drought transition period and monitored with regard to weight and body conditions every 28 days. Total forage mass and percentages of leaf, stem and senescent material were quantified in loco. The estimation of forage quality consumed by animals was performed by the simulated grazing method. There were no significant differences between the levels of inclusion of crambe crushed on animal performance or carcass characteristics. Replacement did not... |

| Objetivou-se, com este trabalho, avaliar os efeitos de fontes de nitrogênio, utilizando-se como volumoso a cana-de-açúcar, suplementada com ureia, glúten de milho-60 ou farelo de soja, sobre o consumo e a digestibilidade aparente total e parcial, em novilhos mestiços. Os tratamentos foram: cana-de-açúcar, cana-de-açúcar suplementada com ureia, glúten de milho-60 ou farelo de soja. Foram utilizados oito novilhos canulados no rúmen e duodeno, distribuídos em dois quadrados latinos 4x4. Para se determinar a digestibilidade aparente no trato digestivo total foi utilizada a coleta total de fezes. As determinações das digestibilidades ruminal e intestinal e dos fluxos diários de matéria seca foram estimadas por meio da fibra em detergente ácido indigestível... |

| This study aimed to analyze the profile of beef sold and consumed in Chapecó – SC, Brazil. Were interviewed 31 individuals responsible for the main distributors, supermarkets, meat markets, restaurants and steakhouses. The structured questionnaire method was used, with questions of closed and open answers applied to those responsible for the establishments previously mapped with greater representativeness in the municipality regarding the characteristics related to the meat trade and the type of product. With the results obtained, it was possible to identify the lack of information regarding the attributes and characteristics that direct preferences in the acquisition of a quality beef. Thus, the knowledge exposure, information dissemination and concepts... |
