The objective of this study was to assess genetic diversity among 5 Brazilian (155 animals) and 5 U.S. goat (120 animals) breeds using 23 microsatellite markers. Samples from the United States represented a broad geographic distribution whereas Brazilian samples were from the northeast region. Samples from Boer were common to each country?s breed count. Expected and observed heterozygosity among breeds ranged from 0.55 to 0.72, suggesting ample genetic diversity in the breeds evaluated. United States Angora, U.S. Spanish, and Brazilian Nambi ranked highest for allelic richness, averaging 6.1, 7.1, and 6.5 alleles per locus, respectively. Angora and Spanish also ranked highest in private alleles (7 and 9, respectively). Using STRUCTURE, the U.S. Spanish were also found to share a common cluster assignment with Brazilian Nambi, suggesting that progenitor breeds may have been the same and passed through the Canary Islands or Cape Verde in route to the New World. When non-Boer breeds were pooled by country, the effect of the subpopulation compared with total population (Fst) = 0.05, suggesting minor genetic differences exist between countries. The lack of genetic structure among goat breeds when compared with other species (e.g., Bos taurus vs. Bos indicus) suggests goat breeds may exhibit a plasticity that facilitates productivity across a wide range of countries and environments. Taken a step further, the concept of breed for meat goats may not be as relevant for goat production.

Em 1984, foi conduzido um experimento em seringal adulto, visando selecionar doses de fungicidas alternativos para o controle de Microcyclus ulei. Foram avaliados os fungicidas Triforine, Bitertanol, Triadimefon e Benomil, aplicados, a intervalos semanais, com um atomizador tratorizado. Empregou-se o delineamento de blocos ao acaso com tres repeticoes e 30 plantas por parcela experimental. A avaliacao consistiu na contagem de foliolos infectados. O fungicida Triforine apresentou um bom desempenho no controle do fungo. |
