Primiparous Cow Calving Season Effects on Calf Weight and Pregnancy Rates

An experiment evaluated the effects of early versus late calving seasons on 54 Red Angus primiparous cows at 24 months of age. The study measured calf weight gain, weaning weight, and pregnancy rates, finding higher efficiency for early calving cows. The dataset originates from research by Eduardo Madeira Castilho, published via Papers with Code.

Use Cases

• Modeling the relationship between calving season and calf weight gain based on reported daily gain and weaning weight metrics.
• Predicting reproductive performance based on synchronization protocols and pregnancy rates mentioned in the description.
• Analyzing productive efficiency metrics such as calf production rate and calf/kg of cow at weaning.

Strengths

• Dataset is based on a controlled experiment with a defined sample size of 54 cows.
• Includes specific quantitative results, such as calf daily gain (0.721±0.030 vs 0.699±0.032 kg) and total pregnancy rates (86.2% and 52%).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
