Micronized cereals in chicken fattening

Cereal thermal processing procedures such as micronization cause significant physico-chemical changes of internal cereal grain structure whereby nutrients become more available to digestive enzymes. This investigation was aimed at indication of effects of micronized cereal application in chicken fattening. The investigation was carried out with 100 chickens of Ross hybrid, divided into an experimental (E) and control (C) group. The mixture composition was the same with both chicken groups, the experimental and the control one. However the experimental chicken group was ted mixtures with micronized corn and wheat. Chickens fattened during 42 days receiving feed mixtures with micronized cereals were growing faster ; thus, achieved higher finalbody weight (2 224 g) and consumed less feed per 1 kg weight gain (1.88 kg) compared to the control group chickens (2 037 g and 2.03 kg). Chickens fed mixtures with micronized cereals had statistically very significantly higher weight of the dressedcarcasses. On the other hand they had statistically significantly lower abdominal fat share (%) in the dressed carcass compared to the control group chickens. No statistically significant differences regarding some carcass part shares as well as shams of muscle tissue, fat tissue with skin and bones in breast and thigh with drumstick were found between the chicken groups. Use of mixtures with micronized cereals in chicken fattening is justifiable considering achieved chicken production resultsand the mixtures price.
