Influence of stallion and insemination technique on embryo recovery rates and pregnancy in a program of embryos transfer in equine Mangalarga breed
Keywords:Equine, Embryo transfer, Mangalarga, Pregnancy
AbstractMany 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%).
