Sensory nerve conduction velocity of the dorsal penile nerves of bulls.

Mean conduction velocity of sensory axons of the dorsal penile nerves of clinically normal bulls was determined by recording action potentials evoked by cutaneous stimulation. Locations of stimulating and recording electrodes were standardized. Overall mean +/- SD conduction velocity was 55.

Mesothelioma in cattle: eight cases (1970-1988).

Over an 8-year period, 8 beef cattle with mesothelioma were admitted to the Auburn University College of Veterinary Medicine and the Louisiana State School of Veterinary Medicine. Diagnosis was confirmed by histologic examination of affected tissues. Five bulls, 1 steer, and 2 cows were affected.

Effects of the anabolic steroid, boldenone undecylenate, on certain reproductive parameters in bulls.

A total of 17 bulls was used to study the effects of boldenone undecylenate on growth and semen characteristics in beef bulls. In trial 1 nine mature mixed-breed beef bulls with satisfactory semen quality were divided into two groups. Group I (n = 5) received boldenone undecylenate (1.

A caudal flank approach for the collection of oviductal-stage bovine embryos.

Oviductal-stage embryos were surgically collected from 27 superovulated adult cows of various breeds, ages, and parity. A total of 88 surgeries was performed via a caudal flank grid approach, with the animals in lateral recumbency and the reproductive tract irrigated with sterile glycerol solution prior to surgical closure. Eight cows were operated on twice and five cows were operated on three or more times.

Incarceration of a section of small intestine by remnants of the ductus deferens in steers.

A 13-month-old Charolais steer was examined because of anorexia and weight loss of 1 week's duration. Initially, the steer passed tarry feces for 2 days, but no feces were passed for 4 days before examination. Palpation per rectum disclosed moderate distention of the small intestine and dark tenacious mucus in the rectum.
