Different selection objectives within the Quarter Horse breed led to the formation of groups with distinct skills, including the racing and cutting lines. With a smaller population size in Brazil, but of great economic representativeness, the racing line is characterized by animals that can reach high speeds over short distances and within a short period of time. The cutting line is destined for functional tests, exploring skills such as agility and obedience. Although the athletic performance of horses is likely to be influenced by a large number of genes, few genetic variants have so far been related to this trait and this was done exclusively in Thoroughbreds, including the g.38973231G>A singlenucleotide polymorphism in the PDK4 gene and the g.22684390C>T single-nucleotide polymorphism in the COX4I2 gene. The results of the present study demonstrate the presence of polymorphic PDK4 and COX4I2 genes in Quarter Horses. The analysis of 296 racing animals and 68 cutting animals revealed significant differences in allele and genotype frequencies between the two lines. The same was not observed when these frequencies were compared between extreme racing performance phenotypes. There were also no significant associations between alleles of the two polymorphisms and the speed index. These results suggest that the alleles of the PDK4 and COX4I2 genes, which are related to better racecourse performance in Thoroughbreds, are probably associated with beneficial adaptations in aerobic metabolism and therefore play secondary roles in sprint racing performance in Quarter Horses, which is mainly anaerobic.

O presente artigo tem como objetivo apresentar os resultados de um levantamento realizado sobre a infra-estrutura turistica de 11 hoteis, localizados na area urbana de Corumba, municipio de Mato Grosso do Sul, que fica no Pantanal Sul, com enfase nos aspectos relacionados a hospitalidade dos empreendimentos hoteleiros. O estudo foi realizado atraves de pesquisa bibliografica e da aplicacao de questionarios nos hoteis urbanos, sendo que o questionario foi elaborado com o objetivo de organizar a coleta dos dados. A pesquisa mostrou que apesar da taxa media anual de ocupacao dos hoteis analisados ser de 60%, a infra-estrutura dos mesmos ainda apresenta inumeros aspectos a serem desenvolvidos e implantados. Os conceitos de hospitalidade, da forma como sao definidos pelo artigo, estao ainda somente no inicio de sua difusao na hotelaria urbana da cidade. Aspectos relacionados ao lazer e a recreacao na hotelaria do municipio sao inexistentes atualmente, o que mostra o amplo potential de desenvolvimento dos empreendimentos hoteleiros do municipio, haja visto a quantidade e qualidade dos atrativos turisticos naturais e patrmoniais de Corumba, que tambem estao sendo relacionada nesse artigo. |
