Resumo: | Many factors can affect pregnancy rates after equine embryo transfer. This study had the objective of evaluating the influence of stallion and of three different insemination techniques (natural breed, artificial insemination with fresh or cold semen), on pregnancy and on embryos recovery rates. In the first year, differences were observed (p < 0.05) in embryo recovery rates among the five stallions studied (28.6, 65.0, 62.9, 66.7 and 84.2%), but no statistical differences (p >; 0.05) were detected in pregnancy rates (50.0, 80.7, 70.6, 70.0 and 62.5%). In the second year, it was observed a tendency to statistical significance (p = 0.057) in embryos recovery rates between the stallions (44.4, 56.2, 71.4 and 73.7%), and no statistical differences (p >; 0.05) were detected in pregnancy rates (75.0, 55.6, 86.7 and 71.4%). There were no statistical difference (p >; 0.05) in the number of embryos transferred and in pregnancy rates comparing natural breed (50.0 and 87.5%) and artificial insemination with fresh (60.6 and 73.7%) or cold semen (63.8 and 80.3%). |

Este estudo teve como objetivo avaliar, em eqüinos da raça Mangalarga e em duas estações reprodutivas, a influência do garanhão e de três diferentes técnicas de inseminação (monta natural, inseminação artificial com sêmen diluído fresco ou resfriado) sobre os índices de recuperação de embriões e de prenhez. No primeiro ano, foram encontradas diferenças significativas (p < 0,05) na recuperação de embriões entre cinco garanhões estudados (28,6; 65,0; 62,9; 66,7 e 84,2%), mas não foram encontradas diferenças significativas (p >; 0,05) nos índices de prenhez (50,0; 80,7; 70,6; 70,0 e 62,5%). No segundo ano, verificou-se uma tendência à significância (p = 0,057), na recuperação de embriões entre quatro garanhões estudados (44,4; 56,2; 71,4 e 73,7%) e não houve diferença significativa (p >; 0,05) nos índices de prenhez (75,0; 55,6; 86,7 e 71,4%). Não houve diferença significativa (p >; 0,05) nos índices de embriões recuperados e de prenhez comparando-se a monta natural (50,0 e 87,5%) e a inseminação artificial com sêmen fresco (60,6 e 73,7%) ou refrigerado (63,8 e 80,3%).Universidade de São Paulo.
