Broiler Chicken Feed Intake by Age: Complete Guide for Farmers

 Introduction

Feed intake is one of the most important factors affecting broiler chicken growth, body weight, and farm performance. As broilers grow older, their daily feed consumption gradually increases. However, feed intake can vary depending on bird age, body weight, feed quality, temperature, health status, and farm management.

Understanding broiler feed intake by age helps farmers monitor flock performance, identify unusual changes early, and manage feed more efficiently. In this guide, we will explain approximate feed intake at different broiler ages and discuss the major factors that can affect daily feed consumption.

Why Is Feed Intake Important in Broiler Chickens?

Feed intake directly affects the growth and development of broiler chickens. Adequate feed consumption provides birds with the energy, protein, vitamins, minerals, and other nutrients needed for healthy growth.

Farmers should monitor daily feed consumption rather than looking only at the amount of feed supplied. A sudden decrease in feed intake may be related to heat stress, poor feed quality, water problems, disease, overcrowding, or other management issues.

Regular monitoring of feed intake can help farmers identify problems early and make better decisions for flock management.

Broiler Chicken Feed Intake by Age

Feed consumption normally increases as broiler chickens grow. The following figures are general reference values, not fixed targets, because actual intake varies by breed, genetics, feed formulation, temperature, health, and management conditions.

Age

Approximate Daily Feed Intake per Bird

1–7 days

15–25 g

8–14 days

30–45 g

15–21 days

50–70 g

22–28 days

75–100 g

29–35 days

105–135 g

36–42 days

140–170+ g

Important: These values should be used as a general guide. Farmers should compare actual feed intake with the performance objectives for their specific broiler strain and feed program.

Factors That Affect Feed Intake in Broilers

Several factors can increase or decrease feed intake in broiler chickens:

1. Temperature

High temperatures can reduce feed intake because birds eat less during heat stress.

2. Water Availability

Clean and easily accessible water is essential for normal feed consumption. Water problems can quickly affect feed intake.

3. Feed Quality

Balanced feed with appropriate energy, protein, vitamins, and minerals supports normal growth and feed consumption.

4. Bird Health

Disease and poor health can reduce appetite and negatively affect growth.

5. Ventilation

Good ventilation helps maintain a comfortable environment and can reduce heat and air-quality problems.

6. Stocking Density

Overcrowding can increase competition for feeders and drinkers and may reduce uniform access to feed.

7. Feeder Management

Feeders should be positioned and adjusted correctly so that birds can easily access feed without excessive wastage.

Practical Feed Management Tips

Provide fresh feed regularly, keep feeders clean, reduce feed wastage, and make sure all birds have easy access to feed.

Feed Intake Monitoring

Farmers should monitor daily feed consumption and compare it with the expected performance of the broiler flock. Sudden changes in feed intake should be investigated promptly, especially when they occur together with changes in water consumption, bird activity, or growth.

Conclusion

Understanding broiler chicken feed intake by age helps farmers monitor flock performance and manage feed more effectively. Feed consumption naturally increases as birds grow, but temperature, water availability, feed quality, health, ventilation, stocking density, and feeder management can all affect intake.

Farmers should monitor daily feed consumption and investigate sudden changes early. Good feed management, clean water, proper environmental conditions, and healthy birds can support consistent growth and efficient farm performance.
