O sistema de producao de gado de corte, desde a preparacao para a estacao de monta ate a terminacao dos animais, necessita de um planejamento sanitario. Esse controle, em uma primeira analise, visa a dar maior seguranca economica ao produtor, pela diminuicao dos riscos de perdas na produtividade do sistema. Ao mesmo tempo, o sistema vai oferecer um produto mais seguro, do ponto de vista sanitario, para o consumidor. Portanto, a viabilidade da resposta dos investimentos no sistema de producao, com relacao ao melhoramento genetico e nutricao animal, vai depender da eficacia da prevencao de doenca no sistema. Este trabalho tem o objetivo de discutir a importancia do planejamento sanitario nas doencas consideradas importantes, sem a pretensao de esgotar o assunto, para a diminuicao dos riscos sanitarios de consequencias economicas para o sistema de producao de gado de corte. |

Abstract Fusarium head blight (FHB) is a disease of wheat (Triticum aestivum L.) that causes major yield losses in South America, as well as many other wheat growing regions around the world. FHB results in low quality, contaminated grain due to the production of mycotoxins such as deoxynivalenol (DON). In Brazil, FHB outbreaks are increasing in frequency and are currently controlled by fungicides which are costly and potentially harmful to the wider environment. To identify the genetic basis of resistance to FHB in Brazilian wheat, two mapping populations (Anahuac 75 × BR 18-Terena and BR 18-Terena × BRS 179) segregating for FHB resistance were phenotyped and quantitative trait loci (QTL) analysis was undertaken to identify genomic regions associated with FHB-related traits. A total of 14 QTL associated with FHB visual symptoms were identified, each of which explained 3.7?17.3% of the phenotypic variance. Two of these QTL were stable across environments. This suggests FHB resistance in Anahuac 75, BR 18-Terena and BRS 179 is controlled by multiple genetic loci that confer relatively minor differences in resistance. A major, novel QTL associated with DON accumulation was also identified on chromosome 4B (17.8% of the phenotypic variance), as well as a major QTL associated with thousand-grain weight on chromosome 6B (16.8% phenotypic variance). These QTL could be useful breeding targets, when pyramided with major sources of resistance such as Fhb1, to improve grain quality and reduce the reliance on fungicides in Brazil and other countries affected by FHB.
