The livelihood of a cow-calf producer relies on reproductively sound cattle that give birth to live offspring once a year. Two factors, pregnancy rate and pregnancy loss, are informative measures of fertility. Herein, the authors identified that pregnancy rates are interactively influenced by estrus activity and reproductive tract size and position scores. Specifically, cows with smaller reproductive tracts that exhibited estrus activity had greatest pregnancy rates. Neither estrus activity, reproductive tract size and position score, nor their interaction were associated with pregnancy loss.
