Estimates of correlation between estrus behavior and estradiol concentrations during estrus [PDF]

, 2021
Estrus traits have economic value in dairy production systems and can potentially be incorporated into genomic selection. Three studies were performed to further understand selection responses. Study one and two explored the relationship between rump touches and number of steps during estrus.
