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...

 An experiment was conducted to evaluate the feeding behavior of feedlot-finished bulls and cull cows in the Cerrado region of Piauí State, Brazil. Forty Zebu cattle were used, of which 20 steers averaging 283.0 ± 20.82 kg initial body weight and 30 months of age; and 20 cull cows averaging 296.1 ± 17.80 kg initial body weight and 100 months of age. Animals were grouped according to the following treatments: bulls and cull cows, using a completely randomized design. Feeding behavior was evaluated by means of visual observations every five minutes during 24h. Results were subjected to analysis of variance by the F test (p &lt; 0.05) using the System for Statistical and Genetic Analysis - SAEG (version 9.1). The feeding behavior was expected not to affect...

Correlation between performance and feeding behavior of feedlot lambs fed without roughage diet
Provedor de dados: 2
Autores: Cardoso, Elves de Souza; Santana Junior, Hermógenes Almeida de; Oliveira, Aracele Prates de; Ferreira, Antônio Hosmylton Carvalho de; Oliveira, Zeliana Fernandes de; Freitas, Tiago Brandão.
The objective was to evaluate the correlation between performance and feeding behavior of feedlot castrated Santa Inês lambs fed without roughage diet, weighing 20 ± 1,8 kg and four months of age (± 0,34). A completely randomized design was adopted. Correlations were obtained by Pearson’s linear correlation analysis and the t test, and processed on SAS software (version 9.2). The variables number of rumination chews per cud, number of cuds ruminated per day, speed of each chew, and number of rumination cuds per day were positively correlated with the variation in body weight (p &lt; 0.05). For number of cuds ruminated per day, a positive correlation was found with the variations in body weight. Initial and final body weights were positively correlated with...
