Abstract: Introduction: White Striping (WS) and Wooden Breast (WB) pectoral myopathies are relevant disorders for con- temporary broiler production worldwide. Several studies aimed to elucidate the genetic components associated with the occurrence of these myopathies. However, epigenetic factors that ...
Um dos desafios para o Brasil e para o mundo nas próximas décadas é a descarbonização da agricultura. O tema está na fronteira do conhecimento científico e depende de vários atores para se chegar a uma solução. O Brasil instituiu política pública para atender às metas...
The behavior of ruminants can influence their productive efficiency. The aim of this study was to evaluate the behavior of young zebu and composite bulls kept in pasture production systems, either in a crop-livestock-forest integration or without afforestation. The work was carried out&...
The characterization of genetic resources is essential to carry out a breeding program. This study aimed to characterize Paspalum genotypes with potential use as soil surface covering to support breeding programs on the development of turf cultivars. Forty-three Paspalum genotypes, comprising...
The objective was to characterize the pastures by grazing cycle, as well as to evaluate the performance of buffaloes in intensive rotational grazing in a silvopastoral system in the eastern Amazon supplemented with agro-industry co-products in order to characterize the grazing cycles, t...
Gastrointestinal nematodes (GIN), especially Haemonchus contortus, represent a significant challenge for sheep production. Given the global concern about GIN anthelmintic resistance, alternative control methods able to reduce the dependence on these drugs are highly advisable. Since previous studies have&#...
The high prevalence of Haemonchus contortus and its anthelmintic resistance have affected sheep production worldwide. Machine learning approaches are able to investigate the complex relationships among the factors involved in resistance. Classification trees were built to predict multidrug resistance ...
Resumo: Este capítulo apresenta uma síntese do histórico, status atual e das tendências futuras na introdução, disseminação e distribuição de espécies exóticas invasoras (EEIs) no Brasil. São abordadas espécies exóticas invasoras em ecossistemas de águas continentais, marinhos e terrestres no Bra...

Haemonchus contortus and Trichostrongylus colubriformis are the most important gastrointestinal nematodes causing serious losses in sheep production of tropical and subtropical regions. Prophylaxis of gastrointestinal nematode infections is based on anthelmintics use, but their frequent administration selects m...
