Sheep production on pasture plays an important role in subtropical climates around the world, with great economic and environmental relevance to those regions. However, this production is much lower than its true potential in subtropical regions, largely due to lack of knowledge of how to feed grazing lambs, and mitigate gastrointestinal parasite infections. Due to weather instability and the high growth rate of tropical grasses, it is difficult to adjust the quality and quantity of feed consumed by lambs. In addition, due to warm, wet weather during spring, summer, and autumn, gastrointestinal parasite infection can be intense on subtropical pastures. Thus, the objective of this paper is to summarize 17 years of research in southern regions of Brazil testing alternative management for sheep farmers under these challenging conditions. Our review indicates that ewes play important roles raising their lambs. Besides protecting and providing milk, they leave a better pasture structure for lamb nutrition. The use of creep feeding and creep grazing are additional alternatives to improve lamb growth. However, feeding supplementation with concentrate can deteriorate pasture quality at the end of the summer?autumn season. Gastrointestinal parasitic infections can be reduced with improved lamb nutrition, although L3 larvae of Haemonchus contortus can be present at various pasture heights. This indicates that it is difficult to control L3 ingestion solely by manipulating grazing heights. We summarize important technologies for raising lambs on pasture-based systems to make the best of high herbage growth and minimize intense parasitic infections common in subtropical regions. We discuss research results in light of the latest studies from other ecoregions and climates, although there is a lack of similar research in subtropical regions of the world.

ABSTRACT: Neonate calves are usually handled a day after birth for navel care and identification. During this procedure the newly calved cows usually become agitated and, in some cases, exhibit aggressive behavior toward humans, increasing the risk of accidents for both, humans and animals. In order to understand the dynamic relationships between cow, calf, and cowhand?s behavior expressed in this particular situation, a conceptual model was built by using the system dynamics methodology. Three dynamic hypotheses were formulated regarding the causeeffect relationship between: i) livestock-handling quality and maternal aggressiveness; ii) livestock-handling quality and newborn calf reactivity, and; iii) newborn calf reactivity and maternal aggressiveness. The first two hypotheses indicated that the improvement (increase) in handling quality will cause an effect in the opposite direction, decreasing cows aggressiveness and calfs reactivity towards the cowhands. The third hypothesis indicated that the greater the calfs reactivity, the greater will be the cow?s aggressiveness, interconnecting cowcalf behaviors. Moreover, the cow, calf, and cowhand subsystems are also comprised of other variables such as human and animal welfare and the occurrence of labor accidents. The combination of these three subsystems constituted a complex general dynamic model highlighting the connection among all agents involved in newborn handling procedure. Despite the complexity it is possible to identify components that promote, simultaneously, human and animal welfare when carrying out newborn calves handling procedures, offering opportunities to develop and adopt system management strategies. In this way, to reduce the risks of labor accidents and the impoverishment of overall welfare it is necessary to focus on three different factors, as follow: i) human behavior, ii) animal behavior, and iii) handling facilities. Thus, it is recommended to implement human capacity-building courses, the culling of aggressive cows and the use of appropriate facilities for the handling of newborn calves.
