Resumo

One hundred and one estral cycles of 92 Mangalarga Marchador breed mares were analyzed to study the effect of different spermatic concentrations on different reproductive characteristics. The mares were inseminated with diluted equine semen, cooled at 20°C and transported: T1 - concentrations below 250×10 6 (177.58±41.74×10 6 viable spermatozoa per inseminate dose), T2 - concentrations between 250 and 350 10 6 sptz (315.51±20.78×106), and T3 - concentrations above 350×10 6 sptz (477.71±136.83×10 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±41,74×10 6 viable spermatozoa per inseminate dose had moderate fertility index in a commercial program using cooled and transported semen.
