Assessment of sexual behavior and effect of semen collection pen design and sexual stimulation of boars on behavior and sperm output-a review
چکیده انگلیسی
The importance of sexual behavior and factors influencing sexual behavior of AI boars has received minimal study. The majority of studies reviewed used a very small number of boars. A sexual behavior index (SBI) has been developed for naturally mating boars but not for AI boars. Some studies have reported significant correlations between sexual behavior traits and semen characteristics; while other studies did not find significant correlations. A new semen collection pen design (Reicks Design) has reduced the duration of time a boar requires to mount a dummy sow after entering the collection pen and the duration of time needed to exit the collection pen after ejaculation. In general, the observation of another boar mounted on the dummy sow prior to collection, releasing the penis after extension, exposing boars to non-estrous gilts for 2 days before collecting semen, placing a non-estrous gilt underneath a dummy, and removing the boar for 2 min after first mount did not enhance the number of sperm cells collected. Treatment of boars with PGF2α has facilitated the training of sexually experienced boars to mount a dummy sow but not that of sexually inexperienced boars. In general, the treatment of boars with PGF2α did not increase the total number of spermatozoa ejaculated.
