What is performance data?

• A. Records of animal productivity
• B. Genetic sequence data
• C. Climate records
• D. Health history only

Answer: (A)

Performance data are records that show how much and how efficiently an animal produces under typical management. They capture actual productivity across traits such as growth rate and weight gain, feed efficiency, milk or egg production, litter size, and reproductive performance. These data are used to compare animals, make selection and management decisions, and track progress over time. They reflect real output and can be influenced by both genetics and environment, which is why adjustments are often made to compare animals fairly.

Genetic sequence data reveals an animal’s DNA information, not how much it produces. Climate records describe weather conditions, not the animal’s performance. Health history relates to disease events and overall health, which can affect performance but does not itself define production outputs.
