Stravitelnost aminokyselin u kuřat chovaných na maso
Foltyn, Marian
The aim of the work was to determine the effect of substitution of soybean meal (SBM) in the grower diets for broilers with other protein feeds of plant origine. It was study the influence of substitution on growth performance and feed conversion ratio, digestibility of amino acids, activity of digestive enzymes and morphology of small intestine. Protein feeds were chosen raw full fat soybean (RFFSB), extruded full fat soybean (EFFSB), corn DDGS, rapeseed (RS) and rapeseed meal (RSM). Based on our observation it can be concluded, that inclusion of RFFSB up to 8 % level, EFFSB up to 12 % level, DDGS up to 18 % level and RS up to 12 % level did not statistically significantly (P>0.05) negatively affect the yields in fed broilers. Feeding RFFSB and EFFSB influenced (P>0.05) the ileus morphology and activity of digestive enzymes. On the basis of digestibility coefficients, the most appropriate proteinous feed for broilers was SBM, which was comparable to EFFSB.
