Abstract
The study was carried out to evaluate on growing pigs kept in metabolism crates, either belonging to a “traditional” cross-breed (Duroc x Large White – DLW) or a local breed (Cinta Senese – CS), the digestibility and the nitrogen balance of non-conventional vegetable protein sources (field beans, pea and sunflower cake) when compared to soybean meal. The four diets were formulated so as to supply the same crude protein amount. CS pigs showed lower apparent digestibility coefficients (ADCs) for crude protein (81,38% vs 82,65%) and crude fibre (35,97% vs 40,65%). Nitrogen balance was more favourable in DLW pigs (32,12% vs 19,67%) which show...
