摘要
要实现奶牛高产必须保证奶牛瘤胃pH值的稳定,要实现瘤胃pH值稳定必须对个体奶牛精饲料量进行精确饲喂,精饲料的数量对瘤胃pH值波动具有重要影响。设计了基于射频识别技术和单片机技术的个体奶牛精确饲喂机,可以实现个体奶牛精饲料量的精确饲喂。通过一个月饲喂实验表明,个体奶牛日产量提高了4 kg。
To realize the high productivity of dairy cow, the pH value of rumen for single dairy cow must be kept stable. The amount of concentrated feed has a significant effect on the fluctuation of pH value. In order to keep the pH value stable, the concentrated feed must be given precisely. Based on the technology of RFID and MCU, a kind of movable precising feeding machine for single dairy cow was designed. This kind of machine can realize the precise feeding of concentrated feed. Through onemonth feeding experiment in the dairy cow farm, the output of milk increases by 4 kg per day.
