Abstract
ABSTRACT The objective of this study was to verify the association of improved native grassland and winter and summer pastures on the weaning rate in beef cattle production. Subsequently, we also verified the socioeconomic and productive characteristics related to the adoption of technologies to increase the weaning rate of the farmers. The survey was conducted with 73 producers of Hereford and Braford cattle in the state of Rio Grande do Sul, Brazil. A data analysis was performed using the minimum [...]

The global perspective for population growth and the increase in demand for beef meat have led to discussions on the rural extension actions needed to promote sustainable food production
The results showed that cattle farmers who adopt winter pastures have greater weaning rates, and the factors that influence this adoption are related to a greater number of employees on the farm and the use of a crop-livestock production system

Summary
The global perspective for population growth and the increase in demand for beef meat have led to discussions on the rural extension actions needed to promote sustainable food production. Forage production has been reduced due to the use of inappropriate management practices (e.g., high animal stocking rate and cultivation in areas without agricultural suitability), causing soil degradation, erosion, and the appearance of species of low nutritional value for animals (Medeiros and Focht, 2007). In this context of pasture shortage, the feeding of cows becomes alarming, since the adequate response in kilograms of weaned calves depends on the conditions to which the cows were subjected.
