Precision feeding in pigs

Development of pig precision feeding

Conventional feeding programs are generally designed to maximize the performance of the herd by providing to all the animals and during long periods of time (for example 30 days) the same feed. However, pigs’ nutritional requirements change dynamically during the growing period and also vary greatly among individuals, even in age- and sex-homogeneous populations. By disregarding this variability, conventional feeding programs lead to a significant nutrient oversupply, usually with diets formulated to satisfy the requirements of the most demanding pigs of the herd. (Pomar, C.; 2014).


In 2004, after a few years of scientific collaboration in the field of development of simulation tools and decision support for the Porcine Sector, a cololaboration between the UdL Research Group (GRAP) and the Dairy & Swine Research and Development Center of Agriculture and Agrifood Canada (AAFC) was done to develope a new technological innovation in the line of increasing competitiveness, sustainability and reducing the environmental impact of pork production. The GRAP, led by Jesus Pomar in the precision livestock area, was responsible for the design and development of robotic intelligent systems for the implementation of the concept of precision feed (hardware, software, Sensors, communications, data processing, etc.), while the AAFC, led by Candido Pomar, was responsible for the development of new knowledge of nutrition, modeling and its validation and calibration in fattening pig.




Based on the results obtained after several research projects carried out in this field, the University of Lleida has developed an intelligent feeder prototype, which improves substantially the production efficiency and reduce the environmental impact. This prototype, which implements the new concept of feeding and intelligent management for farms of IPF (Intelligent Precision Feeder®), is a prototype of non-commercial research that requires the realization of certain experimental developments in order to achieve a product suitable for use in commercial farms.
