The aim of the work presented was to develop a sensor-based control technique for optimal feeding of fattening pigs. In a fattening trial (624 animals) protein utilisation was modified by varying lysine supplementation. Specific sensors recorded feed intake, pig growth, pig environment and liquid manure data. A new approach in this context is the application of a manure sensor based on near infrared spectroscopy. Dependent on gender, higher levels of lysine supplementation led to a lower feed intake, a better feed conversion, a shorter fattening period and a tendency to higher lean meat percentages in the carcass. The relationship of lysine intake and fattening traits can be depicted by the manure nitrogen and ammonium contents.
