Monitoring reproduction in cow-calf operations with metrics like pregnancy rate and weaned calf crop percentage are important for operation success. Weaned calf crop percentage is the most important of these metrics. It is calculated by dividing the number of calves weaned by the number of cows exposed to the bull(s) during the breeding season.
The goal is for weaned calf percentage to be at least 85% and preferably even a little higher. Low body condition score at calving is the most common reason for low reproductive rates. Other potential reasons include disease challenges or fertility issues in bulls.
