the aims of the present study were to propose apolymerase chain reaction-restriction fragment length polymorphismpcr-rflp genotyping method for the ay_376689:c.773c>t single nucleotide polymorphism snp of the equine prkag3 gene, related to muscle performance, as well as to characterize this snp and a second polymorphism, aawr_02017454:g.121684t>c of the spata1 gene, related to male fertility, i...

The aim of this study was to evaluate the influence of physical exercise (marcha gait) on heart rate variability indices in Mangalarga Marchador horses. Twenty-five animals, fourteen females and eleven males, aged 6.4 ± 2.7 years and with a mean weight of 428.3 ± 24.7 kg, were used. Electrocardiograms were recorded at two different time points: rest and immediately after exercise (40 min of aer...

Knowledge of genetic diversity and relationships between breeds is very important for conservation programs. Hair samples were collected from 393 individual Nordestino horses and genotyped using 14 microsatellite markers in order to investigate the genetic relationship between this breed and 66 international horse breeds. There was high allelic diversity and inbreeding coefficient within popula...

The objective of this work was to estimate genetic parameters and evaluate trends over 26 years for morphometric traits in Mangalarga Marchador horses. Twelve were evaluated (withers croup heights; length head, body, shoulder, croup, neck, back, loins; width head cannon bone thorax perimeters). These 38,341 animals born between 1987 2012 with a relationship matrix 77,719 animals. Gibbs sampler ...

The Mangalarga Marchador (MM) breed, which originated in Brazil, constitutes the largest number of horses country. animals are versatile and used several sports because major investments made for genetic improve-ment breed. In recent decades, advances molecular techniques enabled identification diseases hor-ses. Conducting tests determining occurrence mutations fundamental early prevention abno...

One hundred and fifteen unrelated Mangalarga Marchador horses were sampled from three geographically distinct regions of Minas Gerais State, Brazil (South, Southeast, and Northeast) and tested for 10 microsatellite loci. Genetic diversity and population structure parameters were estimated with ARLEQUIN 3.0, CERVUS 2.0, POPGENE 1.31, GENEPOP on the web, STRUCTURE 2.0, and SPAGEDI 1.2 software pa...

ABSTRACT Luxation of the temporomandibular joint (TMJ) in horses, despite being an uncommon condition, is often associated with local trauma involving head. Its clinical importance mainly related to painful injury and impairment multiple movements involved chewing breaking foods. The objective current work describe manual reduction technique TMJ dislocation a 6-year-old Mangalarga Marchador sta...
