Evaluation of sexual behavior of stallion (Arabian versus Barb) during breeding season in Algeria

This study was carried out at National Haras of Tiaret (west of Algeria) to understand and to compare the normal sexual behavior and libido of stallions (Arabian vs Barb) while mounting a mare in estrus. Eighty-four stallions were divided into two groups from 5 to 24 years of age (n=47 Arabian; n=37 Barb). Results revealed significant differences between Arabian and Barb stallion: in sniffing (p less than 0.001), libido score (p less than 0.05), flehmen response (p less than 0.05), time to first mount with erection (p less than 0.05), number of mounts to ejaculation (p less than 0.05) and mount time for ejaculatory (p less than 0.01). These stallions were exactly tested in the same place and conditions allowed us to discard any side effects due to animal management or any other confounding bias. Our study provided us the knowledge of sexual behavior under Algerian environmental conditions and the distinction between Arabian and Barb stallion in their sexual behavior expression.
