title: The efficiency of two nonsurgical techniques for bovine embryo recovery on days 6 and 7 of the estrous cycle.
abstract: Two nonsurgical techniques for embryo recovery were employed and used in Days 6 and 7 of the estrous cycle. A significant difference between techniques was observed in both days of collection, with the closed system being more efficient in Day 6 and the opened one more efficient in Day 7. The bacteriological contamination of flushing medium (11% for the closed system and 21% for the opened technique) was of saprophytic bacteria and did not affect the percentage of pregnancies in either system.
