The objectives of this study were to determinate the scrotal shape and evaluate skin thickness vascular hemodynamics using Doppler ultrasonography in Braford bulls. This experiment was performed at a farm located municipality Santana do Livramento, Rio Grande Sul state, Brazil. A total 106 bulls, 16 months old, housed under extensive breeding conditions. mean temperature on day measurements taken 22.6 ± 2.9 °C, relative humidity 78 9%. These values used calculate Temperature Humidity Index...
Forty-eight Holstein cows were assessed using infrared thermography as noninvasive diagnostic tool for subclinical mastitis detection.The temperature analysis of animals negative in the California Mastitis Test has evidenced a difference between mean temperatures front and rear quarters (p=0.001).The comparison positive not shown any (p=0.236),but results (32.35ºC ±2.35) CMTs (31.00ºC ± 2.20 (p=0.025).The use seems to be promising; however, it is necessary determining protocol guide its use.
The aim of this study was to evaluate the dynamics scrotal temperature, sperm quality and testicular blood flow by using infrared thermography Doppler ultrasonography in bulls submitted insulation. Braford (n = 8) at 18 months age, were assigned into following groups: insulated for 72 h (G 72; n 2), 96 96, 120 120, control animals (CON; 2) that remained without Infrared parameters measured four different time points: immediately after insulation (M0), within 10 min (M10), 30 (M30) 60 (M60)...
The aim of this study was to compare the biometric testicular characteristics, skin thickness and haemodynamics artery 12- 24-month-old bulls using Doppler ultrasonography, conducted 48 indicus-taurus animals. scrotal circumference (SC) biometry characteristics were measured calculate volume. ultrasonography used obtain haemodynamic values artery. volume lower (p<.01) in younger (12 months:4.68 ± 0.68 mm; 168.76 47.96 cm3 ) versus 24 months (5.05 0.89; 499.73 129.24 animals (p<.01). During...

RESUMO: A vesiculite é um processo inflamatório das glândulas vesiculares, podendo ser unilateral ou bilateral, que acomete reprodutores. O objetivo do presente trabalho foi avaliar a utilização da ultrassonografia como meio de diagnóstico precoce alterações vesículas seminais em touros. realizado no município Videira, Santa Catarina. Analisou-se total 42 reprodutores, com média idade 15 meses, raças Aberdeen Angus e Polled Hereford semi-confinamento. Foi exame clinico estado geral dos...
O objetivo deste estudo foi estimar a correlação entre o perímetro scrotal (PE) e idade de touros Aberdeen Angus. Os dados relativos aos PE 248 foram obtidos partir um banco exames andrológicos pertencentes Embryo Inc., Turlock, Califórnia, Estados Unidos da América, realizados 2006 2011. criados em sistema semi-intensivo na região do vale São Joaquim. A média 15,4 (± 1,5) meses médio 36,8 (±2,9) cm. Para análise estatística utilizada linear Pearson com nível mínimo significância. positiva...
Background: The mechanisms of testicular thermoregulation may influence the blood flow provided by artery, where proper supply to testicle is crucial for promotingspermatogenesis and reproductive function in bulls. size shape testicles are determined genetic environmental effects. A better understanding relationships between anatomical characteristics scrotum can support a assessment. purpose current study was evaluate temperature different scrotal shapes using infrared thermography...
Parâmetros biométricos, como formato testicular, espessura de pele, são importantes na avaliação da hemodinâmica testicular e, pode contribuir para compreensão dos mecanismos termorreguladores em animais domésticos. O objetivo deste estudo foi avaliar as características biométricas relação a utilizando ultrassonografia Doppler. Foram avaliados 52 machos 12 meses idade raça Brangus (3/8 Brahman x 5/8 Aberdeen Angus) por meio parâmetros velocidade média (VM), sistólica (VP), diastólica (VE),...
