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 (AMEN) 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, AMEN value, AMEN/ gross energy ratio and phytic-P content in pea (r = –0.52, r = –0.31, r = –0.42, P ≤ 0.05, respectively)

The nutritional value of four cultivars of Lupinus angustifolius L. seeds was investigated. The experiment was conducted on 50 male 16-day-old Ross 308 chickens. The birds were randomly allocated to five dietary treatments (10 replications each). Digestibility was calculated using the difference method. The basal diet and four diets composed of ground lupin seeds (cv. Sonet, Boruta, Graf or Neptun) and the basal diet at a proportion of 25:75 (w/w) were prepared. The birds were fed the diets starting from day 16; on days 19 and 20 of life, excreta were individually collected, then all chickens were sacrificed and ileal digesta was sampled for determination of ileal digestibility. Ileal dry matter digestibility ranged between 56.8% and 62.5% (P < 0.05). The apparent ileal digestibility of aspartic acid, proline, alanine, valine, histidine and lysine was negatively correlated (P < 0.05) with the in vitro water extract viscosity (WEV) of lupin seeds. The apparent metabolizable energy (AMEN) ranged from 7.91 to 9.27 MJ · kg–1, the lowest was determined for cv. Graf, the highest for Boruta and Sonet. The Graf cultivar was also characterized by the lowest dry matter ileal and total tract digestibility (P < 0.05). The AMEN of lupin seeds was negatively correlated with WEV (r = –0.67; P < 0.05) and raffinose level (r = –0.72; P < 0.05). The relationship between raffinose content and AMEN was linear (P < 0.05).

nr 1
In the first study conducted to investigate the nutritional value of raw and extruded narrow-leafed lupin (Lupinus angustifolius) seeds cv. Boruta, 60 male Ross 308 chickens of age 16–20 days were used (Experiment 1). In 35-day performance trial (Experiment 2), 960 1-day-old chickens were randomly allotted to 11 treatments and fed diets containing 0, 50, 100, 200, 250 or 300 g · kg−1 diet of raw or extruded narrow-leafed lupin seeds. In the first experiment, extrusion of narrow-leafed lupin seeds led to the decrease of neutral detergent fibre (NDF) concentration. Seed processing increased fat digestibility and nitrogen retention in chickens but had no effect on ileal digestibility of protein and amino acids. There was a tendency to increase the apparent metabolizable energy corrected to zero N balance (AMEN) after lupin extrusion. In the second experiment, the inclusion of increasing levels of raw or extruded seeds into diets quadratically decreased body weight gains (BWGs) of birds, except for broilers fed extruded lupin on days 15–35. The extrusion increased the BWGs of birds in the whole trial period (days 0–35). Increasing levels of raw and extruded narrow-leafed lupin seeds quadratically increased feed conversion ratio during the experiment. So, the extrusion of narrow-leafed lupin seeds had a limited positive effect on the chemical composition of seeds and growth performance of broiler chickens.
