The Brazilian domestic market demands sheep products in quantity and quality. The disponibility of these products can be achieved through the increase in numbers of animals in production and/or the increase in productivity. The usual crossbreeding systems and the formation of composite groups can contribute to increase production efficiency, through heterosis and complementarily. These tw…
Beef production in Brazil has been attained mainly in extensive systems on pasture, where the animals, generally of low genetic potential, are exposed to a seasonal lack of forage and little health control. Intensive beef production can contribute significantly to the Brazilian beef industry, since it favors the rational utilization of the production factors and the potential and genetic …
Brasil stands out among the ten world's largest sheep herds, and has presented, in the last years, an expressive increase in the number of animals, especially in the Southeast, Midwest and Northeast regions of the country, producing mainly meat. In the opposite way, the South region, considered a reference in wool and meat production is facing an important decline of its herd. This change…
One of the strategies to increase production is the formation of composite groups that, through the use of heterosis and complementarity among breeds, can contribute to increase efficiency in sheep production. However, the advantages of crossbred over pure animals in the production of good-quality leather depend on the breeds involved in the crossings and on the rearing environment. Sheep…
Under heat stress conditions, increases in respiratory frequency is the more important mechanism used by sheep to dissipate heat, especially in wool-on breeds. However, non-wool or semi-wool sheeps have more possibilities to exchange heat by skin, mainly by increasing the sweating rate. Thus, the objective of this study is to evaluate characteristics and types of sweat glands found in dif…
