Abstract
Chicken is a major economic animal in Thailand. Processed chicken, especially, frozen and chilled
chicken are leading export products. Normally, farmers determine the weight of broilers by randomly
catching and weighing broilers periodically. As a result, broilers are hurt by being caught. The objectives of
this study are 1) to design and develop the calculating model to find mass weight of broilers and 2) to
compare the death rate of broilers. We designed and developed the model based on the principles of load cell that converts a load or force acting on load cell into an electronic signal. The processing unit
will send the signal to the controller to calculate the weight of broilers. The system will analyse and
compare the weight to standard values and the result will be displayed on screen. Based on the study in
laboratory, the calculating model could calculate the weight of different objects and display results on
screen accurately. For the test in broiler house, the calculating model could also determine broiler mass
weight and show results correctly. Thus, farmers can use this device to decide which broilers to catch for
further production. This new method of determining mass weight of broilers is reduced the death rate of
broilers approximately 81% due to catching by hands. In the future, this system should be designed and
developed to be compatible with smart phone and tablet in order to be more flexible.
