RESUMO: Objetivou-se avaliar níveis de inclusão da casca de banana sobre as variáveis fisiológicas de vacas F1 Holandesas × Zebu em lactação. Foram utilizadas 10 vacas distribuídas em dois quadrados latinos 5×5. Sendo cinco dietas experimentais: silagem de sorgo (grupo controle); e a inserção de 15, 30, 45 e 60% da casca de banana em substituição a silagem de sorgo. O experimento teve duração de 80 dias. Mensuraram-se as variáveis ambientais e fisiológicas dos animais. O índice de temperatura de globo negro e umidade encontrada no turno matutino apresentou uma situação de alerta e no turno vespertino uma situação perigosa. A frequência respiratória foi influenciada pelos níveis de inclusão de casca de banana no turno vespertino. A temperatura retal não foi influenciada pelos níveis de inclusão de casca de banana na dieta. Sob as condições ambientais estudadas, o nível de até 60% de casca de banana, em substituição a silagem de sorgo, não alterou as variáveis fisiológicas de termorregulação em vacas F1 Holandesas × Zebu.

ABSTRACT: The objective was to evaluate the effects of different levels of banana peel inclusion on the physiological variables of lactating F1 Holstein × Zebu cows. Ten cows distributed in two 5 × 5 Latin squares were used. Five experimental diets were tested: sorghum silage (control group); and the addition of 15%, 30%, 45%, and 60% of banana peel to replace sorghum silage. The experiment lasted 80 days. The environmental and physiological variables of the animals were measured. The Black Globe-Humidity Index presented an alert situation in the morning shift and a dangerous situation in the afternoon shift. The respiratory rate was not influenced by the levels of banana peel inclusion (P > 0.05) in the morning shift. However, it was influenced (P < 0.05) in the afternoon shift. The levels of banana peel inclusion in the diet did not affect the rectal temperature. Under the study environmental conditions, the level of up to 60% of banana peel replacing sorghum silage did not alter the physiological variables of thermoregulation in F1 Holstein × Zebu cows.

RESUMO Objetivou-se determinar índices zoométricos, correlacionar e predizer o peso corporal a partir das medidas biométricas de fêmeas F1 Dorper × Santa Inês (F1 D × SI) criadas extensivamente. Foram acompanhadas 25 fêmeas ovinas F1 D × SI, com idades variando de 2 a 9 meses. Mensurou-se mensalmente o peso corporal, perímetro torácico, perímetro de barriga, comprimento corporal, altura de cernelha, altura de garupa, largura de garupa, comprimento de garupa e a partir dos mesmos estimou-se os índices zoométricos. Realizou-se análise descritiva dos dados, correlação de Pearson e análise de regressão. As medidas biométricas e os índices zoométricos das fêmeas F1 D × SI indicam um animal de aptidão para corte, com boa conformação, além disso, demonstram aspectos favoráveis para reprodução, característica fundamental na seleção de matrizes. O peso corporal apresenta correlação alta e positiva para todas as características analisadas, com valores variando de 0,74 do comprimento de garupa a 0,88 de perímetro torácico. As regressões para todas as medidas biométricas foram altamente significativas (P<0,0001) com destaque para o perímetro torácico que apresenta o maior coeficiente de determinação (R² = 0,77), as demais medidas apresentaram abaixo de 0,70. Conclui-se que as fêmeas F1 Dorper × Santa Inês apresentam características para produção de carne e para reprodução. E que das medidas biométricas, o perímetro torácico, pode ser utilizado para predição do peso corporal das fêmeas F1 Dorper × Santa Inês.

ABSTRACT The objective was to determine zoometric indices, correlate, and predict body weight based on the biometric measurements of F1 Dorper × Santa Inês (F1 D × SI) ewes created extensively. Were 25 F1 D × SI sheep monitored, with ages varying from 2 to 9 months. Body weight, thoracic perimeter, belly perimeter, body length, withers height, rump height, rump width, and rump length were measured on a monthly basis and zoometric indices were estimated from them. Descriptive data analysis, Pearson's correlation, and regression analysis were performed. The biometric measurements and zoometric indices of F1 D × SI ewes indicate an animal of aptitude for cutting, with good conformation. In addition, they demonstrate favorable aspects for reproduction, a fundamental characteristic in the selection of matrices. Body weight has a high and positive correlation for all characteristics analyzed, with values ranging from 0.74 of the rump length to 0.88 of the thoracic perimeter. The regressions for all biometric measurements were highly significant (P <0.0001) with an emphasis on the thoracic perimeter that has the highest coefficient of determination (R² = 0.77), the other measures presented below 0.70. It was concluded that F1 Dorper × Santa Inês ewes have characteristics for meat production and for reproduction. Also, of the biometric measurements, the thoracic perimeter can be used to predict the body weight of F1 Dorper × Santa Inês ewes.

ABSTRACT The objective of this study was to evaluate the effect of the trainer and the adopted daily work on the behavior and performance of horses of the Mangalarga Marchador breed on a horse farm and in racetracks in northern Minas Gerais State, Brazil. Twenty equines and nine trainers from four farms and three competition events of the breed were observed. The experiment was divided into two stages. In the first stage, the animals were observed together with their trainer on the farm, during the daily work, and the behavior reactions were recorded based on scores. The duration of training and the behavior told by the trainer of the animal were recorded in scores. The second stage happened in three competitions of the breed in agricultural fairs. The same observations were made on horse farms, including the behavior of the animal, before and after the trial, as well as the emotional state in the same period. For data analysis, multivariate statistics were used based on the principal components and factor analysis, using the statistical software R (version 3.3.2). From the data analyzed, it was verified that the variables embouchure, behavior and voice of the presenter, and reward and incentive in the competition influenced the reactivity of the animal. Variables of human behavior in training influenced the animal behavior variables in training. The behavior of the trainer and the form of the training, as well as the fact that the trainer is the presenter, interfered in the behavior of the horses on the horse farm and in the competitions, resulting in safer animals. However, the need for time adaptation and training management is necessary for the whole man × animal relation to get better rankings in the race competitions.
