Treść
Raw or extruded peas (Pisum sativum, pink-flowered cv. Milwa)were used. Extrusion reduced the trypsin inhibitor activity (TIA) from 2.35 to0.35 mg · g–1, but did not affect tannins content, which was about 1 g · kg–1.A growth trial was conducted on 200 Ross 308 female broilers from day 1 to35 of age. There were 3 treatment groups from day 1 to 14 including controlwithout peas, 10% raw (RP) and extruded (EP) pea. From day 15 birds werekept individually, in groups of 18, and fed diets containing 15%, 20%, 25%, or30% RP and EP. Chickens fed EP ate more feed (P ≤ 0.05) but had similar bodyweight gains and worse feed conversion ratio (P ≤ 0.05) than chickens fed RP.The apparent ileal digestibility (AID) of dry matter was lower in chickens fed EPthan RP (P ≤ 0.01), whereas AID of protein did not differ. The AID of starch was0.835 in the control group, in chickens fed both RP and EP it was, on average,2 percentage points higher (P ≤ 0.01). In birds fed RP the short-chain fatty acidconcentration in ileal digesta was lower (P ≤ 0.05) whereas in caecal digestahigher (P ≤ 0.01) than in birds fed EP. The dietary treatments had no effect onjejunal mucosa morphology. Diets containing up to 30% of peas with a relativelylow tannins content and moderate TIA value, can be fed from the third weekof life as a partial substitute of soyabean meal in broiler diets. The effects ofpea extrusion on ileal nutrient digestibility and activity of gut microbiota was toosmall to affect performance.
