摘要
No presente estudo avaliaram-se aspectos relacionados ao comportamentodi芍rio e reprodutivo de f那meas bovinas mesti as (Zebu x Holandesa) portadoras de dermatite digital, durante um per赤odo de 24 meses. Os bovinos foram distribu赤dos em tr那s grupos (GI, GII, GIII), compostos por dez animais cada. No GI foram alocadas f那meas bovinas portadoras de dermatite digital na forma erosiva, no GII na forma verrucosa eo GIII composto por animais clinicamente saud芍veis. No comportamento di芍rio e alimentar, os animais foram observados no piquete e durante a ordenha. Avaliaram-se a atitude do animal, se em posi o quadrupedal ou dec迆bito, per赤odo de alimenta o, frequ那ncia de ingest o de 芍gua, tempo de rumina o e 車cio. Quanto ao comportamento reprodutivo, estudaram-se o per赤odo de servi o, presen a de cisto ovariano, reten o de envolt車rios fetais, metrite, sinaisexternos de cio, consist那ncia dos ov芍rios e do 迆tero, n迆mero de servi os, prenhez e parto. Ao final do estudo, concluiu-se que a dermatite digital bovina, especialmente do tipo verrucosa, alterou de forma negativa o comportamento di芍rio e alimentar de f那meas bovinasmesti as (Zebu x Holandesa), observadas em diferentes situa es. Com rela o ao comportamento reprodutivo, ao relacion芍-lo 角 presen a ou aus那ncia de dermatite digital, n o foi poss赤vel observar diferen as entre os grupos, em rela o aos parametros avaliados. This present study aimed to evaluate aspects related to daily and reproductive behavior of female crossbred (Bos indicus x Bostaurus) cattle bearing digital dermatitis, raised semi-extensively, during 24 months. The animals were distributed in three groups (GI, GII, and GIII) with ten animals each. GI received cows bearing the erosive type of digital dermatitis, whilst GII received those ofverroucous type and GIII received clinically healthy animals. Animals were observed during milking and grassing for daily and feeding behavior. Animal behavior was evaluated, whether standing or lying, as well as feeding period, frequency of water ingestion,rumination time and leisure. The reproductive behavior was studied as: service period, ovarian cyst presence, fetal envoltory retention, metritis, external signs of estrous, consistency of ovaries and uterus, number of services, pregnancy and birth. At the end ofthe study, it was possible to conclude that digital dermatitis, especially in verrucous presentations, do interfere negatively in daily behavior of female crossbred cattle. However, there was no evidence of differences in reproductive behavior among the evaluated groups.
