Embryo quality and development in sub-fertile dairy cows

Abstract

Embryo Transfer (ET) is a valuable tool that producers can use to decrease the generation interval and/or quickly increase the genetic potential of the herd. Several factors affect the implantation and establishment of pregnancy with embryos such as fresh vs frozen, produced in vivo vs in vitro, and disease in the recipients. The objective of this study was to investigate the effect of embryo quality and subclinical endometritis (SCE) in Holstein Friesian recipient cows on early embryonic death (EED) between d 7 to d 16.
