title: Effects of single deep insemination on transferable embryo recovery rates in superovulated dairy cows.
abstract: Thirty superovulated Friesian lactating cows were randomly assigned to two groups. Group I donors were inseminated with one unit of semen deposited into the uterine body at 8, 20 and 32 h after the onset of estrus. Group II donors were inseminated with one unit of semen deposited deep into the uterine horns at 15 h after the onset of estrus. Neither the mean rates of fertilized ova nor the mean rates of transferable embryos were different between treatments (P > 0.05).
