Effects of LH administration at the end of an FSH superovulatory regimen on ovulation rate and embryo production in three breeds of sheep.


In 3 experiments, 168 ewes of Manchega (n = 72), Churra (n = 62), and Merina (n = 34) breeds were used to test the hypothesis that administration of pure LH, coincident with progestogen removal during superovulation with FSH, causes an increase in the ovulation rate and number of embryos. This administration of LH can further interact with genotype… (More)
