Effect of ewe restraint on the libido and serving capacity of rams

Applied Animal Behaviour Science 35(4): 339-345
Effect of ewe restraint on the libido and serving capacity of rams
The following study examines the effect of ewe restraint when assessing the libido and serving capacity of rams. Twenty-five domestic rams were exposed to both unrestrained and restrained estrous ewes under circumstances in which copulations were permitted and prevented. Ewe restraint did not affect the rate of ejaculation or measures of precopulatory behavior when copulation was permitted. When rams were exposed to ewes whose perinea had been covered to prevent copulations (libido tests), bouts of leg-kicking and anogenital sniffing were not afforded by female restraint but mounting occurred more frequently when ewes were unrestrained. The latter measures of libido correlated with ejaculation rates (serving capacity) observed in tests permitting copulation and, in four out of six cases, were slightly higher when covered females were restrained. Rams were particularly aggressive (bulls and vigorous pawing) toward ewes that were covered and restrained. It was concluded that the advantages of ewe restraint are not great enough to justify its use when assessing the libido and mating potential of rams with estrous ewes.
