Contents Electroejaculation procedures ( EEP s) provoke stress; nevertheless, ejaculation produces physiological changes similar as those usually used to measure stress responses. The application of animals that cannot ejaculate—as ewes—may be useful discriminate the responses induced by from provoked . aim was determine response in rams and ewes. EEPs were applied 10 ewes during non‐breeding season, number vocalizations, heart rate, rectal temperature, serum cortisol concentration,...
In some domestic ruminants, contact with females is necessary for normal development of sexual behavior.The aims this experiment were to determine if rearing bucks isolated from does affects negatively their behavior when adults, and negative effect overcome after four short contacts females.Sixteen Saanen male kids maintained during one year in two groups: reared permanent direct adult goats (FEM; n = 7), that remained (ISO; 9).When 12 mo-old, removed both groups joined the FEM pen.Nine...
In both captive wildlife and production animals is important to develop strategies for population control. Immunization against GnRH an easy inexpensive immunocastration method that reduces the concentration of testosterone decreases sperm quality. However, its effectiveness depends on species repetition treatment. This study aimed compare a single treatment (initial immunization plus booster with Improvac) vs repeated (six doses inhibit testicular function maintain contraceptive status...
Abstract Transrectal ultrasonic‐guided massage of the accessory sex glands (TUMASG) is a technique that allows collecting semen requiring few electrical stimuli or even no pulse. A long‐acting analogue oxytocin (carbetocin, 0.1 mg) was i.v. administered before TUMASG in 10 conscious bucks (Experiment 1) and anaesthetized Iberian ibexes 2) to shorten time collection, decrease number and/or improve quality. The ejaculated volume, concentration, quality parameters kinetics variables sperm were...
