Nutrient Management Plan Section 1: Animal Inventory

Purpose:

To assemble the necessary inputs for estimating manure nutrient excreted by an animal feeding operation. A generic estimate of manure nutrient excretion can be made by collecting farm data for:

• Meat animals – Number of animals finished per year.
• All other animals – One-time animal capacity of animal housing.
• Portion of year facility is occupied.

The generic estimate assumes all animals are fed the same diet and achieve the same performance. This assumption can produce large errors in estimating manure nutrients.

A more accurate, farm-specific estimate of manure excretion can be made by collecting:
  1. Average daily feed intake.
  2. Concentration of nitrogen and phosphorus in the ration.
  3. Species specific animal performance information.

Software:

Nutrient Inventory Spreadsheet* (MS Excel file, 1.84MB) for an animal feeding operation. Use for estimating
  1) the amount of N, P, and total quantity of manure excreted by animal feeding,
  2) the quantity of available nutrients after storage and land application, and
  3) the land requirement for utilizing remaining nutrients at an agronomic rate.
