Abstract: The experiment was carried out with 50 preliminary sexing one day old chicken of both sexes in an
experimental and control group, obtained from the lines of the Poultry Hybrid Center gene pool. The rearing
was in a group to 49 days of age with constant assess (ad libitum) to combined forage, corresponding to
their age and category.
The control group chicken received the traditional combined forage for the corresponding period, and
the experimental ones - combined forage with 10% pea. During the experiment were measured the chicken
live weight by individual measurement with the accuracy of 1g at the age of 1, 14, 28, 42- и 49 days. The
group forage consumption and its utilization was taken into account for the periods from hatching to 14-
days of age, from 14 to 28 days, from 28 to 42 and from 42 to 49 days of age.
At the end of the experimental period a slaughter analysis was performed on eight characteristics after 12
h non-feeding on three male and female chickens with live weight average for the group. On that basis were
calculated the slaughter yield and the proportion between the different body parts.
The growth intensity was maintained at a high level to 49-days of age of the male and female chicken
broilers fad with combined mixture with 10% pea grain and reached average live mass of 1949.34 g and
1891.28 g respectively.
The forage consumption for 1 kg gain during the whole period was with 11.69% and 10.27% lower
respectively for the female and male chicken from the experimental group.
The broiler chickens fad with combined forages with 10% pea to 49-days of age had a higher live mass,
mass of the oven-ready carcasses (bratfertig), thighs, grill, breasts, and giblets.
