Area of Science:

Animal Science
Agricultural Engineering
Biotechnology

Background:

Efficient broiler feeding is crucial for production success.
Traditional methods lack real-time data for agile farm management.
Broiler feed intake directly impacts growth and economic outcomes.

Purpose of the Study:

To develop and evaluate a smart feeding unit (SFU) prototype.
To measure broiler pecking force and average feed intake per pecking.
To assess the SFU's efficiency in continuous feed intake monitoring.

Main Methods:

A prototype SFU was developed with a data acquisition module and video camera.
Seven Cobb-500 broilers were used to test the prototype in an experimental chamber.
Feed intake was calculated by measuring feed consumed and pecking counts within the first minute.

Main Results:

The average broiler pecking force was 1.39 N (range: 0.04–7.29 N).
Average feed intake per pecking (FIP) was 0.13 g, with 173 peckings/min.
Signal acquisition and processing of pecking force data proved valuable.

Conclusions:

The SFU prototype efficiently assesses broiler feed intake in real-time.
The technology provides valuable data for estimating broiler performance.
This system supports more precise and agile decision-making in broiler production.
