Abstract

The aim of this study was to quantify the effects of progesterone profile features and other cow-level factors on insemination success to provide a real-time predictor equation of probability of insemination success. Progesterone profiles from 26 dairy herds were analyzed and the effects of profile ...

AbstractFull Text

The objective of the present work was to evaluate the effect of treatment of estrus cycle control (Co-Synch 5 days; J-Synch or Device by 7 days), reproductive status (cyclic or anestrus) and equine chorionic gonadotropin (eCG) on pregnancy rate after fixed time artificial insemination (FTAI). Angus ...
