Cow-calf pregnancy distribution information from records collected at the time of pregnancy diagnosis

Abstract

Identifying factors that influence pregnancy success is important for both veterinarians and producers to optimize management decisions. The study objective was to evaluate pregnancy diagnosis histograms, and determine if factors such as herd size, breeding season length, body condition of cow, age of cow, or the season of year affected the likelihood of pregnancy at the end of the first 21-day interval and at the end of the breeding season.
