Livestock Record Keeping: What to Track for Profitability

Livestock · November 2025 · 5 min read

Good livestock records separate profitable operations from those that just hope for the best. Tracking individual animal performance reveals which animals earn their keep and which ones cost you money. Consistent record keeping also supports health management, breeding decisions, and marketing with data instead of guesswork.

Individual Animal Identification

Every record-keeping system starts with reliable individual identification. Ear tags are the most common and affordable method, but they can be lost. Using a combination of visual tags and a permanent method like tattoo, brand, or electronic ID (EID) ensures each animal can always be identified. EID tags allow rapid data capture with a wand reader during processing.

Assign each animal a unique ID number at birth or purchase and use it consistently across all records. A simple numbering system (year + sequential number, such as 25-001) makes it easy to identify an animal's age at a glance.

Essential Records to Track

The core records that drive management decisions include birth date, sire and dam, birth weight, weaning weight, and health treatments. These data points allow you to calculate adjusted weaning weights, compare sires, and identify cows that consistently produce above-average calves. Health treatment records document what was given, when, and withdrawal periods for food safety compliance.

• Breeding dates and bull exposure periods for calving predictions
• Calving records including ease of birth, vigor, and any complications
• Weight records at weaning, yearling, and sale for growth tracking
• Death loss with cause of death to identify herd health patterns
• Feed and input costs per head or per group for profitability analysis

Using Data for Herd Improvement

Records are only valuable if you analyze them and act on the results. At minimum, calculate each cow's annual output in pounds of calf weaned per cow exposed. Cows that fail to wean a calf, wean a light calf, or require excessive inputs should be identified for culling. The bottom 10 to 15% of producers in any herd are typically costing you money.

Use breeding and calving records to tighten your calving season by culling late-breeding cows. Compare sire groups by progeny weaning weight and disposition to guide future bull purchases. Whether you use a smartphone app, spreadsheet, or paper notebook, consistency matters more than technology. The best record system is one you will actually use every day.
