How This Calculator Works

The Poultry Feed 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.

📐 Feed Consumption & Bag Formulas

Daily Feed Consumed (kg) = (Number of Birds × Daily Feed Intake Per Bird in Grams) ÷ 1,000 Total Feed for Period (kg) = Daily Feed (kg) × Number of Days Feed With Wastage (kg) = Total Feed (kg) × (1 + (Wastage % ÷ 100)) 50 kg Feed Bags Required = Feed With Wastage (kg) ÷ 50 (Rounded up to next whole bag) Feed Cost Per Day (Rs) = Daily Feed (kg) × Feed Price Per kg Total Estimated Feed Cost (Rs) = Feed Bags Required × Price Per 50 kg Bag

Worked Example: Step-by-Step Practical Calculation

Scenario: A farmer needs to calculate total feed for 1,500 broilers during the 4th week of rearing (Day 22 to Day 28, 7 days) with an estimated intake of 135 grams/bird/day.

Starting Assumptions:

Number of Birds: 1,500
Daily Feed Intake: 135 grams per bird
Duration: 7 days
Wastage Margin: 3%
Bag Size: 50 kg (Standard Pakistan Feed Bag)
Price Per 50 kg Bag: Rs. 8,250 (Rs. 165/kg)

Calculation Steps:

Step 1 — Daily Feed: (1,500 birds × 135g) ÷ 1,000 = 202.5 kg/day

Step 2 — 7-Day Net Feed: 202.5 kg/day × 7 days = 1,417.5 kg

Step 3 — Add 3% Wastage: 1,417.5 kg × 1.03 = 1,460.03 kg

Step 4 — Number of 50 kg Bags: 1,460.03 kg ÷ 50 kg = 29.2 bags → Order 30 bags

Step 5 — Estimated Total Cost: 30 bags × Rs. 8,250 = Rs. 247,500

Step 6 — Feed Cost Per Bird for the Week: Rs. 247,500 ÷ 1,500 = Rs. 165.00/bird

Frequently Asked Questions Common questions about Poultry Feed Calculator

A commercial broiler (Cobb 500 or Ross 308) in Pakistan consumes approximately 3.2 kg to 3.6 kg of feed over 35 to 38 days to reach an average target weight of 1.9 kg to 2.1 kg, corresponding to an FCR of 1.65 to 1.75.

In Pakistan, commercial poultry feed from major mills (such as National, Big Bird, Supreme, Islamabad, and Jadeed) is standardized in 50 kilogram woven polypropylene bags.

Typical farm feed wastage ranges from 2% to 5% due to pan feeder spillage, rodent theft, and moisture contamination. Adding a 3% buffer prevents emergency shortages during weekend transport delays.

Commercial broilers transition through four key feeding phases: Pre-Starter Crumble (Days 0–7, 23% CP), Starter Crumble/Pellet (Days 8–18, 21% CP), Grower Pellet (Days 19–28, 20% CP), and Finisher Pellet (Day 29 to market, 18.5% CP).

An adult commercial layer hen in active egg production consumes between 105 grams and 120 grams of layer ration daily, depending on breed (Brown vs. White), ambient temperature, and egg mass output.

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.
