Based on the concept that horses have balanced symmetry between its anatomical regions, the aim of this study was to introduce a method of assessing the balance of equines through body proportions. Altogether twelve linear measurements, using metric tape, were measured in 234 horses Quarter Horses for evidence of barrel racing. From these measurements were built nine body proportions, each one given by the ratio of two specific measures, and the effects of sex, weight, age and degree of blood on the balance were evaluated. To check the significance tests we used the F statistic, considering P<0.05. It was found that the linear measurements ML2, ML3 and ML5 were mainly responsible for the disproportionality of the horses evaluated. The effect of sex was significant (P<0.05) for four proportions (R1, R3, R4 and R9) and females were more distant from the concept of balance than males.

With highlighted sprint ability, the racing line is important segment within the Quarter Horses breed, with huge impact on agribusiness. Theseanimals have noted morphological differences when compared to other lines within the breed, especially for larger body size proportions.The objective of this study was to estimate genetic parameters forbody measurements traitsof the racing line of the Quarter Horses breed via Bayesian inference. Here,289 animals of both sexes, registered at brazilian association of breeders (ABQM), were used. The results showed high coefficient of heritability for body length (0.74) and back-loin lenght(0.61). The heritability coefficients for height at withersand croup length were moderate (0.44 and 0.47, respectively). High genetic correlation for body length and croup length and for body length and back-loins lengthwas also observed(0.80 and 0.76, respectively). Taking into account the estimates of heritability and genetic correlations between body measurement traits, the body length and height at withers traits proved to be appropriate to provide future researches that investigate the genetic correlation between body measurements and racing performance.

Uma potra da raça Quarto de Milha com dois meses de idade apresentava aumento de volume bilateral na região da parótida desde algumas horas após o nascimento. Por exame radiográfico diagnosticou-se timpanismo bilateral de bolsa gutural. Realizou-se a abertura cirúrgica da bolsa gutural esquerda e fenestrou-se o septo medial das bolsas guturais. Adicionalmente, procedeu-se à ressecção parcial da mucosa na abertura do orifício guturo-faríngeo. A afecção foi debelada, sem recidivas.
