A practical everyday tool for poultry farm supervisors, shed managers, and feed store operators. Enter bird counts, individual intake, and feeding duration to calculate exact kilogram requirements and rounded-up bag orders across standard 50 kg, 40 kg, 25 kg, or custom bag sizes.
The Feed Bag Calculator applies standard avian zootechnical mathematics calibrated specifically for Pakistani poultry production norms. Whether modeling 35-day Cobb 500 broilers in Punjab or commercial brown layers in KPK, the engine accounts for feed intake curves, bird mortality, utility overheads, and prevailing mandi price mechanics.
📐Bag Conversion Formulas
Daily Total Feed (kg) = (Number of Birds × Daily Feed Intake in Grams) ÷ 1,000
Total Period Feed (kg) = Daily Total Feed (kg) × Feeding Days
Exact Bags Required = Total Period Feed (kg) ÷ Bag Weight (e.g. 50 kg)
Rounded-Up Bags To Order = ceil(Exact Bags Required)
Buffer / Remaining Feed (kg) = (Rounded-Up Bags × Bag Weight) − Total Period Feed (kg)
Worked Example: Step-by-Step Practical Calculation
Scenario: A supervisor managing 4,200 broilers in Week 3 (eating 95 grams/bird/day) needs to place a 4-day feed order with standard 50 kg bags.
Frequently Asked Questions
Common questions about Feed Bag Calculator
Feed bags should never be stacked directly on bare concrete floors or against outer walls to prevent moisture absorption and mould. Always stack on wooden pallets raised at least 4 inches off the floor, with maximum 10 bags high.
Under dry, ventilated storage conditions in Pakistan, commercial pelleted feed maintains full nutritional potency for 30 to 45 days. In humid monsoon conditions (July–August), feed should be used within 15 to 20 days to avoid aflatoxin contamination.
Birds generate internal metabolic heat when digesting feed. During cold winter weather, intake increases by 5%–10% as birds eat more to maintain body warmth. In extreme summer heat, intake drops by 15%–25% to prevent heat stress.
Yes. While 50 kg is the commercial standard in Pakistan, this calculator allows you to select 25 kg, 40 kg, or enter any custom bag size for premixes, concentrates, or international packaging.
Poultry Farming Estimation Notice:
These calculations are estimates provided for informational and planning purposes. Actual poultry farming costs, feed performance, Feed Conversion Ratios (FCR), mortality, mandi market prices, and net profitability vary depending on farm shed ventilation, bird genetics, feed quality, seasonal temperatures, management practices, and local market conditions across Pakistan. Always verify binding commercial transactions with registered wholesale mandi dealers or local District Market Committees.
