Precision farming is a method for achieving higher productivity in plant and livestock productions. The higher productivity is obtained through optimizing feed consumption and therefore, reducing the cost of production. Due to lack of economic justification in many applications, the precision farming has not been prevalent. Fresh dairy cows are very sensitive to quantity and quality of concentrate intake after postpartum.Amount of concentrate feed (energetic feed) on the first day after calving is low (3 to 5 kg) while it must be increased gradually (4 to 5 times) during less than four weeks. Precise control of concentrate consumption (increasing 400 to 600 grams per day) for fresh cows is considerably effective on health, peak of milk production and animal life time. In this research, a device was designed and constructed which is capable of controlling individual feed intake for the cows kept in groups. The main criteria considered in the design of the system were: 1) safety of animal and device 2) easy installation without any significant changes in livestock building, 3) user friendly, 4) automatic control of all necessary processes and 5) capable of being economic and commercial. The main components of the system are: 1) an electro-pneumatic rotary gate for feed trough, 2) a Radio Frequency Identification (RFID) system, 3) a weighing system, and 4) a control and central processing unit (CPU). The identification system consists of a reader and some ear tags. The reader sends the information of the tag to the CPU through a RS232 interface. Also, a load cell and a signal conditioner continuously send the weight of trough feed through a SPI interface to the CPU. The CPU controls all processes related to the identification, registration and measurement of concentrate consumption, updating and controlling the electro-pneumatic rotary gate of the feed trough. The software of the control system can be set in three modes: A) ID configuration for each animal, B) act as monitoring system for the weighing system and C) the ready mode. The first mode is use to define the amount of concentrate in the first day after calving and daily concentrate increment. The second mode is used to calibrate the weighing system and to be informed about the amount concentrate left in the feed trough. The system is normally adjusted in the third mode; in this mode, all processes necessary for accurately controlling the individual concentrate consumption, are executed automatically based on the number of postpartum days. The devices was evaluated in simulated condition similar to individual cow feed intake. .
