Twenty Holstein-Friesian breeding bulls (62-79 months of age) were examined 3 times, at 30-day intervals. Scrotal thermograms for assessment of scrotal surface temperature (SST) and blood samples for plasma testosterone concentrations were taken just

The objective was to determine the effect of time of day (diurnal variation), interval after feeding, prolonged recumbency, moisture on the scrotum, and ambient temperature on scrotal surface temperature (SST) in bulls as measured by infrared thermog

Sixteen 2-yr-old beef bulls were used in the study. Under caudal epidural analgesia (xylazine HCl, 40 mg), infrared thermography was used to determine scrotal surface temperature (SST) and needle thermistors were used to determine scrotal subcutaneou

Scrotal/testicular thermoregulation is a complex process controlled by numerous local mechanisms that attempt to maintain the testes at conditions ideal for spermatogenesis. This article provides a background of the anatomy and physiology of the bovi

The infrared temperature pattern (IRT) of the scrotal surface was recorded for 73 yearling beef bulls and a color video thermogram of the pattern of each bull was recorded. The average scortal surface temperature, temperature at the top and bottom of

The objective of this study was to determine the contribution of the scrotum, testes, and the testicular artery to scrotal/testicular thermoregulation in bulls at two ambient temperatures. Crossbred beef bulls, 1.5 years of age, were placed in contro

Nine Simmental X Angus bulls (2-yr of age) were used in 2 experiments. In Experiment 1, the scrotal neck was insulated (from Day 1 to Day 8) in 5 bulls, and semen was collected from all 9 bulls by electroejaculation approximately every 3 d until Day
