and creatine kinase muscle (CKM) (g.22999655C>A) genes have been associated with optimum racing distance and muscle development and racing performance in Thoroughbred horses, respectively. Considering that, since its formation, the Quarter Horse breed has received important genetic influence from the English breed, the genes cited become important candidates for athletic performance in the racing line of the American breed. An SNP in the equine doublesex and mab-3-related transcription factor 3 (DMRT3) gene (g.22999655C>A) has been described, which is responsible for the gait phenotype in homozygous individuals. Using a sample of 296 Quarter Horses of the racing line and 68 animals of the cutting line, the objective of this study was to compare the frequencies of the three SNPs cited above between a random subsample of animals of the cutting line (n ¼ 20) and animals with extreme phenotypes for racing performance (n ¼ 20 per extreme phenotype). The MSTN SNP showed practically no variation, with the observation of only one heterozygous animal (CT) in the cutting line, suggesting that this gene has been under great selective pressure within the racing segment. The CKM gene variant studied was found to be polymorphic, but no significant associates were observed between its alleles and the different lines or groups. Two animals carrying the CA heterozygous DMRT3 genotype were identified in the group with poor racing performance and one in the cutting line, indicating that this variant can be a limiting factor for the development of greater speeds.

Integrated management approaches are essential for the sustainability of the beef cattle production system in the Pantanal wetland, and it would direct the adoption of adequate management practices that favor multiple ecosystem services and biodiversity. This paper exemplifies the evaluation of the pasture attributes in a ranch at the Nhecolandia sub-region, Pantanal. The evaluation is based on an indicator of natural pasture conservation status (PCS) applied to landscapes with dominance of native grasslands. To estimate the net primary productivity (NPP) and forage provision, the vegetation at two different landscapes was mapped, one with "regular" and another with a "good" PCS performance. Grassland landscape with "good" PCS presented more than three times NPP than the "regular" one, reflecting the greater forage provision and grazing capacity. This result indicates the PCS indicator is suitable to differentiate among grassland condition with potential positive impact on animal performance and ecosystem services. The integration of different complementary evaluation tools provides useful information for decision making on sustainable grassland management. |
