How to scientifically calculate laying materials for laying hens

One of the most significant costs in raising laying hens is feed. Properly managing the amount of feed given to hens at each stage of their growth can greatly improve the profitability of poultry farming. Drawing from over 30 years of hands-on experience in chicken farming, I would like to share some scientifically sound feeding methods for laying hens. These guidelines are intended to help farmers optimize their feeding practices and enhance productivity.

For chicks under 10 days old, the daily feed amount per bird can be calculated as: age in days + 2. For example, a 6-day-old chick should receive 8 grams of feed per day (6 + 2 = 8 g).

For chicks aged between 11 and 20 days, the formula changes to: age in days + 1. A 15-day-old chick would need 16 grams of feed per day (15 + 1 = 16 g).

Chicks between 21 and 50 days old should be fed an amount equal to their age in grams. So, a 28-day-old chick would get 28 grams of feed daily.

For hens aged 50 to 150 days, the daily feed amount is calculated as follows: 50 + (age - 50) ÷ 2. For instance, a 100-day-old hen would receive 75 grams of feed per day (50 + (100 - 50) ÷ 2 = 75 g).

Once hens reach 150 days or older, they can be fed a stable amount of 100 grams or more per day. This helps maintain their health and egg production levels.

Using these scientifically based feeding strategies, a hen will consume approximately 8.84 kg of feed by the time it reaches 150 days. Annually, a laying hen will require about 36.5 kg of feed, which is sufficient to support egg-laying while minimizing waste. By following this approach, farmers can achieve higher efficiency and better returns on their investment in poultry farming.
