In a trial carried out on broiler chickens, the nutritive value of five pea cultivars (coloured-flowered: Turnia, Sokolik, Milwa, and white-flowered Muza and Cysterski) was determined. A total of 60 male Ross 308 17-dayold chickens were assigned to six experimental groups (10 replications per treatment). Apparent ileal digestibility of amino acids (AID AA) and the value of apparent metabolizable energy (AME_N) were determined. Pea cultivars vary in their contents of tannins (Sokolik 0.48 g · kg^–1, Cysterski 0.05 g · kg^–1), raffinose family oligosaccharides (Milwa 72.4 g · kg^–1, Turnia 88.5 g · kg^–1), as well as phytic-P (Muza 4.4 g · kg^–1, Turnia 2.1 g · kg^–1). The study showed positive correlations between starch content and AID AA (P ≤ 0.05), as well as negative correlations between total tract dry matter retention, AME_N value, AME_N/ gross energy ratio and phytic-P content in pea (r = –0.52, r = –0.31, r = –0.42, P ≤ 0.05, respectively).
