RESUMO.-As variações nos parâmetros hematológicos são utilizadas com intuito de avaliar o grau de treinamento ou estado clínico do animal. A avaliação hematológica de eqüinos em repouso tem sido objeto de estudo, a fim de estabelecer uma relação com treinamento ou capacidade atlética. Objetivou-se avaliar o perfil hematológico de eqüinos submetidos à prova de Team Penning, correlacionando o sexo e freqüência da atividade física. Mediante punção da veia jugular externa coletaram-se dois mL de sangue de 29 eqüinos, 18 machos e 11 fêmeas, em repouso (Momento I) e após o exercício (Momento II Variations in hematologic parameters are used to assess the degree of training or clinical state of the animal. The hematologic evaluation of horses at rest has been an object of study in order to establish a correlation with training or athletic capacity. The purpose of this study was to evaluate the hematologic profile of horses subjected to Team Penning competitions, correlating sex and frequency of physical activity. Two milliliters of blood were drawn through a puncture made in the external jugular vein from 29 horses, 18 males and 11 females, at rest (Moment I) and after exercising (Moment II). The blood samples were processed in an ABC VET automated veterinary hematology analyzer (Horiba ABX Diagnostics). The animals were divided into Group A, B, C and D according to the number of times they participated in the competition. The values of globular volume, hemoglobin, erythrocytes, rod-shaped segmented neutrophils and monocytes increased after the physical exercise, unlike the number of lymphocytes and eosinophils, which decreased. A comparison of the before/after exercise correlations showed no significant differences (p<0.05) between males and females. In addition, it was found that the value of the MI/MII ratio for the globular volume, hemoglobin and number of erythrocytes varied according to the frequency of the exercise. It was concluded that the Team Penning competition produces hematologic alterations in horses, which are affected by the frequency of exercising, regardless of sex.INDEX TERMS: Equus caballus, exercise, hematology.

Diseases of the reproductive system are common in both sexes in the most varied of species. In female dog, these diseases produce different degrees of morbidity and mortality and are influenced by environmental conditions, reproductive history, and previous drug treatments. Reproductive disease may have different consequences, ranging from the absence of clinical signs to the impairment of fertility. The objective of this study was to determine the causes of reproductive diseases in female dogs admitted to the Veterinary Hospital, Federal University of Uberlândia, during a six-year period (2012-2017) and to identify the most frequently occurring diseases. Information relative to the species, age, breed, and sex of 32,944 were obtained for animals. Of these, 16,480 were female dogs and 1,185 were diagnosed with alterations to the reproductive system. The animals were divided into four groups according to age (puppies, young adults, adults, and old) and disease of the reproductive system (Group 1 - vaginal and vulvar alterations; Group 2 - alterations to the estrous cycle, ovary, and uterus; Group 3 - alterations to the gestational period and parturition). The highest occurrence of diagnoses (47%) was recorded in young adult female dogs (1 to 5 years old). The most frequent alterations in female dogs were pyometra (48.8%), dystocia (13.6%), and transmissible venereal tumor (TVT) (12.6%). Crossbred dogs were the most affected with alterations to the reproductive system, representing 60% of all the female dogs diagnosed with any pathologic alteration. In conclusion, a 7.2% occurrence of reproductive disorders shows the relevance of these diseases in small animals and suggests that new methods are needed for the prevention, early diagnosis, and treatment of these disorders.
