1. Typology of beef production systems according to bioeconomic efficiency in the south of Brazil
RESUMO: O objetivo deste estudo foi avaliar a eficiência bioeconômica em sistemas de produção de bovinos de corte no sul do Brasil. A pesquisa foi realizada com 33 pecuaristas que operam com sistemas de produção baseado em ciclo completo, em áreas maiores ou iguais a 900 hectares. As respostas foram classificadas em dois fatores: tecnologia (TEC) e g

2. Understanding heat stress in beef cattle
ABSTRACT Thermal stress is the result of a misbalance between heat produced or gained from the environment and the amount of heat lost to the environment. The level of thermal stress can range from minor or no effect to death of vulnerable animals. Under summertime conditions, thermal stress results in hyperthermia or heat stress. Heat stress in feedlot catt

4. Economic and socio-environmental performance assessment of beef cattle production systems: a data envelopment analysis (DEA) approach with weight restrictions
This study evaluated the performance of 21 beef cattle modal production systems that conduct only the raising phase. These production systems were developed in 21 municipalities in seven Brazilian states. We used two different DEA BCC models, corresponding to different points of view. Firstly we used an economic model that measured the ability of a productio

5. Economic values for milk production and quality traits in south and southeast regions of Brazil
The objective of this study was to calculate economic values for milk (MY), protein (PY) and fat productions (FY) and somatic cell count (SCC) which could be used to compose an economic index to rank animals involved in an international genetic evaluation program of Holstein cattle used in the commercial dairy population in Brazil. The main milk production s

6. Effects of supplementation frequency on the ruminal fermentation and enteric methane production of beef cattle grazing in tropical pastures
The objective of this study was to evaluate the characteristics of ruminal fermentation and enteric methane production in beef cattle subjected to different supplementation frequencies while grazing on Brachiaria brizanthacv. Marandu pastures. Nine cattle (325±65.7 kg BW) fitted with ruminal and duodenal cannulas were used in the ruminal fermentation study,

7. Avaliação econômica da terminação de bovinos em pastagem irrigada / Economic evaluation of finishing of cattle in irrigated pasture
The adoption of new technologies with the aim of intensifying the production of beef cattle has increased in recent years. Irrigation of pasture is one of these alternatives on the rise and this study aimed to determine the economic viability of finishing cattle by measuring the production costs and financial indicators. This study evaluated three production

8. Reduction of the bull:cow ratio in the Brazilian Pantanal.
This work was conducted to study alternatives for reduction of the bull:cow ratio in the Brazilian lowland and, therefore, lower the production costs for the local beef cattle industry. The ratios 1:10, 1:25, and 1:40 were used in native pastures with a mean stocking rate of 0.27 mature animal unit per hectare over two consecutive breeding seasons. Statistic

9. Formulação de dietas de custo mínimo da matéria seca para bovinos de corte em planilha eletrônica.
ABSTRACT: The diet is one of the main costs animal production in feedlots. In addition, diet composition is one of the main determinants of the animal's performance. Therefore, adequate diet formulation is crucial for the success of the feedlot. This publication describes the fundamentals of diet formulation through the criteria of least cost of dry matter a
