The mares were inseminated with diluted equine semen, cooled at 20 degrees C and transported: T1-concentrations below 250 x 10(6) (177.58 +41.74 x 10(6) viable spermatozoa per inseminate dose), T2-concentrations between 250 and 350 10(6) sptz (315.51 +/- 20.78 x 10(6)), and T3-concentrations above 350 x 10(6) sptz (477.71 +/- 136.83 x 10(6)). The conception rates in the first cycle were 43.75 (7/16), 57.89 (11/19)and 54.55% (18/33) for treatments 1, 2 and 3,respectively. After five cycles, the conception rates were 36.00 (9/25), 44.12 (15/34) and 54.76% (23/42) for treatments 1,2 and 3, respectively. Concentrations of 177.58 +/- 41,74 x 10(6) viable spermatozoa perinseminate dose had moderate fertility index in a commercial program using cooled and transported semen.
