Resumen
The effects of extender and farms on the fertility of sixty-five Mangalarga Marchador breed mares were studied. The mares were randomly assigned to a 2 × 2 factorial experiment, with two breeding farms (H1 and H2) and two extenders (glycine-egg yolk - T1 and lactose-egg yolk modified - T2), from only one stallion, with different number of replicates . The mares were inseminated, on alternated days, with diluted, cooled, transported semen, in a special container (MSP-2). There were no differences in the conception rate at first cycle, regardless of the breeding farm or extender used. Also, there was no difference among breeding farm or extender concerning the conception rate/cycle and the following reproductive characteristics: number of cycles/pregnancy, number of inseminations/ mare, inseminations/pregnant mare, inseminations/open mare, water temperature in the container, temperature of semen in the container, time between collection and insemination and efficiency of pregnancy. The use of lactose-egg yolk modified extender for the dilution, cooling and transport of stallion semen between farms is recommended. The new container MSP-2 showed to be a option for the transportation between farms, for the same purpose.
