| RESUMO Desde tempos remotos, a pelagem é valorizada no agronegócio equestre. Em animais Campolina, objetivou-se avaliar a ocorrência de pelagens e a distribuição entre sexos nos estados do Brasil, assim como verificar a frequência desse fenótipo nos acasalamentos e associá-lo com medidas lineares e qualidade da marcha. Foram selecionados 44.437 registros definitivos e utilizaram-se testes de qui-quadrado para avaliar a distribuição de pelagens entre sexos, estados e décadas. Por análise descritiva, foi obtida frequência de acasalamento dos fenótipos e proporções resultantes nos filhos. Foram contabilizados os indivíduos acasalados e os mais usados por décadas de nascimento e de registro. Pelagens baia, alazã e castanha predominaram, com 20.422; 11.941 e... |

| Circadian rhythmicity of physiological processes in animals has been described for some variables. In order to investigate the daily rhythmicity of blood pressure, seven foals (Equus caballus) were used for 40 days after birth. Measurements of blood pressure were done by means of an oscillometric apparatus (Argus TM-7, Schiller, Barr Switzerland) with the foals in a standing position and the cuff placed around the tail. Blood pressure was recorded twice a day, 1 hour before dawn and 1 hour before dusk for the first 10 days of life, every 2 days from the 11th to the 32nd day, on the 36th and on the 40th day. Two-way repeated measures analysis of variance (ANOVA) were used to determine statistically significant differences between the mean values recorded at... |

| Aimed to evaluate the coat and Quarter reproductive age used in equine production used in Vaquejada in micro regions of the Northeast. They used information from 264 horses, taken from the database of the Association of Quarter Horse Breeders (ABQM). Were collected individual information: date of birth, sex and animal fur, number of copies of disputed official Vaquejada, better and worse placed, cumulative score in ABQM, coats and dates of parents' birth (31), coats and birth dates mothers (257). There was a higher frequency (P<0.05) of births between the months of September and October. There was no age-specific greater use of stallions or matrix playback (P>0.05). There was no correlation (P>0.05) between the number of children and the stallion... |

| ABSTRACT: This study aimed to determine and compare corneal sensitivity values in different regions of the cornea in five horse breeds. One hundred and forty five healthy horses, adults of both sexes, of the following breeds - Arabian horse (AH; n=20), Mangalarga Marchador (MM; n=50), Pure Blood Lusitano (PBL; n=35), Quarter Horse (QH; n=20), Brazilian Sport Horse (BSH; n=20)-were investigated. Corneal touch threshold (CTT) was measured with a Cochet-Bonnet esthesiometer in five different corneal regions. Measurements of the median central CTT were: 4.50±0.50cm (AH), 3.50±0.56cm (MM), 3.00±0.25cm (PBL), 2.50±0.44cm (QH) and 2.50±0.00cm (BSH). The central region was the most sensitive and the dorsal region the least sensitive corneal region for all breeds.... |

| Abstract The first horses were brought to Brazil by the colonizers after 1534. Over the centuries, these animals evolved and adapted to local environmental conditions usually unsuitable for exotic breeds, thereby originating locally adapted Brazilian breeds. The present work represents the first description of maternal genetic diversity in these horse breeds based on D-loop sequences. A D-Loop HSV-I fragment of 252 bp, from 141 horses belonging to ten Brazilian breeds / genetic groups (locally adapted and specialized breeds) were analysed. Thirty-five different haplotypes belonging to 18 haplogroups were identified with 33 polymorphic sites. Haplotype diversity (varying from 0.20 to 0.96) and nucleotide diversity (varying from 0.0039 to 0.0239) was lower... |

| RESUMO O objetivo deste estudo foi avaliar a atividade predatória do fungo Duddingtonia flagrans contra larvas infectantes (L3) de nematoides gastrintestinais na pastagem e no bolo fecal de equinos, em um período de 21 dias. O delineamento experimental foi inteiramente ao acaso, com três grupos tratados (G1, G2 e G3) e um controle (C), com oito animais/grupo. Os tratados receberam 1,5x105; 3x105 e 6x105 clamidósporos de D. flagrans/kg-1peso vivo animal, G1, G2 e G3, respectivamente, durante 21 dias, com administração a cada três dias. Foram delimitadas 36 áreas de 1m2 cada, equivalendo a repetições em triplicata para cada grupo. As fezes foram coletadas dos animais nos dias 0 (D0), 15 (D15) e 30 (D30 = sete dias após a última administração dos tratamentos)... |

| The objective of this work was to evaluate the genetic diversity of Brazilian Pantaneiro horse by microsatellite markers, investigate the effect of genetic bottlenecks and estimate genetic differentiation among four horse breeds. Genetic variation was estimated through allele frequencies and mean breed heterozygosity. Nei's genetic distances among the breeds Pantaneiro, Thoroughbred, Arabian, Spanish Pure Breed (Andalusian), and Uruguay Creole were calculated, and it was used to construct an UPGMA dendrogram. Clustering at different K values was calculated to infer population structure and assign individuals to populations. Nei's distances showed a minimum distance between Pantaneiro horse and Spanish Pure Breed (0.228), and similar distances from Spanish... |

| Los bovinos y equinos criollos americanos son descendientes directos de los animales introducidos al Nuevo Mundo por los europeos durante los siglos XV y XVI. En los comienzos de la década pasada, surgieron tecnologías basadas en el estudio del ADN que permitieron profundizar el análisis genético, por su parte, las especies criollas americanas no quedaron fuera de dichos estudios. En los últimos años, estas metodologías evolucionaron en forma vertiginosa, y en poco tiempo, el aumento de información creció significativamente de modo tal que las investigaciones pasaron de unos pocos loci a la secuenciación y el análisis de los genomas completos de ambas especies. En el presente trabajo se describe como ha evolucionado el estado del arte de la genética... |

| En Argentina existen numerosas poblaciones de caballos cimarrones (Equus caballus), varias de ellas en áreas naturales protegidas. Estos grandes herbívoros son considerados especies exóticas invasoras y a altas densidades pueden causar serio impacto sobre la biodiversidad. En otros países sus poblaciones han sido intensamente manejadas, en nuestro país el manejo ha sido discontinuo, y solo se ha reducido temporalmente la población del Parque Provincial Tornquist, en la provincia de Buenos Aires. El caballo es muy apreciado por el público y existe un rechazo a su manejo. Solo métodos considerados humanos, como la captura viva y posterior adopción o el control de fecundidad son aceptados. Es fundamental basar el manejo en el conocimiento científico, de... |

| Genetic variation in Zemaitukai horses was investigated using mitochondrial DNA (mtDNA) sequencing. The study was performed on 421 bp of the mitochondrial DNA control region, which is known to be more variable than other sections of the mitochondrial genome. Samples from each of the remaining maternal family lines of Zemaitukai horses and three random samples for other Lithuanian (Lithuanian Heavy Draught, Zemaitukai large type) and ten European horse breeds were sequenced. Five distinct haplotypes were obtained for the five Zemaitukai maternal families supporting the pedigree data. The minimal difference between two different sequence haplotypes was 6 and the maximal 11 nucleotides in Zemaitukai horse breed. A total of 20 nucleotide differences compared... |

| Abstract: The objective of this work was to evaluate the development of the morphometric characteristics of Mangalarga Marchador horses through nonlinear models. The transversal method was used to collect data on height at the withers (HW), body length (BL), and thoracic (TP) and cannon (CP) perimeters from 200 horses (75 males and 125 non-pregnant females), aged between 6 and 153 months. The parameters of the Brody, Gompertz, logistic, and von Bertalanffy nonlinear models were estimated using the R software. Models were compared and selected using the coefficient of determination, the residual standard deviation, and the corrected Akaike information criterion. For adult females, HW, BL, TP, and CP ranged between 146.45-148.34, 148.59-151.64,... |
