Research and Experiment of Growth Data Acquisition System for Large-scale Group-reared Broiler Breeders

In order to solve the problems such as the difficulty in collecting growth data and the intensity of data recording and sorting when the growth performance of broiler breeders was measured by means of group rearing, a growth data acquisition system suitable for large-scale breeding of broiler breeders was designed. The growth data acquisition system of broiler breeder consists of an electronic bracelet, an automatic measuring device and a data management platform. The results show that the system can realize electronic identification of individual chickens, automatic acquisition of weight value and feed intake, real-time recording of feeding events of individual or group broiler chickens, and automatic generation of feed conversion. The drop rate of the electronic leg ring worn by individual chickens was less than 0.5%, the identification accuracy was more than 99.9%, and the data acquisition accuracy was more than 99.6%. This study shows that the designed growth data acquisition system can obtain data intelligently for the growth performance verification test of broiler breeders in large-scale group breeding mode, effectively reduce breeding cost input, and provide technical support for the intelligent determination of broiler breeders.
