Pig Feed Guide: Practical Rations, Cost Control, and Growth Tracking

Feed cost is usually the largest line item in a pig operation. If feed management is loose, margins disappear even when market prices are decent. This guide focuses on practical feed planning you can run weekly.

Quick Answer

Match feed phase to growth stage, track intake by pen, and calculate cost per pound gained. Adjust quickly when growth lags or waste rises.

Feed Planning by Stage

Starter stage

Use nutrient-dense feed and minimize stress. Intake can be inconsistent, so clean water and consistent routine matter.

Grower stage

Balance protein and energy for steady frame development. This is where poor feed management usually starts to show.

Finisher stage

Optimize for efficient gain and carcass target. Avoid abrupt ration changes close to finish.

Daily Operational Rules

  • Check feeder function every day.
  • Keep feed dry and rodent-protected.
  • Record intake by pen and compare to weight gain.
  • Separate underperformers early so dominant pigs do not suppress intake.

Cost Control That Actually Works

  • Track delivered feed price by lot.
  • Measure spill and wastage points.
  • Use a simple weekly feed conversion trendline.
  • Do not chase cheap feed that creates health or growth penalties later.

Common Failure Points

  • Ignoring water flow rates.
  • Overstocking feeders.
  • No pen-level tracking.
  • Late response to growth stalls.
