Abstract
An experiment was carried out on 200 Ross 308 chickens, which were divided randomly into 5 equal number groups. All birds were fed mixtures prepared on maize and wheat 50:50, but the factor differentiating the groups was the physical form of wheat (ground or whole grain) according to the following design: I group (control) – 100% wheat as a ground, II – 75% ground + 25% whole grain, III – 50% ground + 50% whole grain, IV – 25% ground + 75% whole grain, V– 100% whole grain. It was shown that the feeding used did not influence the body weight of birds but signifcantly differentiated the feed conversion ratio. Chickens fed the mixtures containing only whole grain of wheat obtained the lowest dressing percentage, the worst musculature and the highest adiposity. Breast muscles of chickens fed a diet with a higher share (>50%) of whole wheat had more crude protein (P ≤ 0.05) but lower crude fat (P ≤ 0.05). The meat of experimental birds was less acid and darker. The applied feeding did not have (P > 0.05) any influence on water holding capacity (WHC).
