EFFICIENCY OF EXTRUDED CONCENTRATED FEEDSTUFF APPLYING IN EARLY BREEDING OF BROILERS

The paper reveals research results on influence of feeding broilers with extruded concentrated feedstuff in the early period on the growth rate and mortality rate of the poultry from its first day to 37th day. The experiment was carried out on boilers of cross IZA F15 in OOO “Kuzbasskiy broiler” of Kemerovo region. The authors arranged the control group and experimental one; each of them contained 120 broilers. The researchers fed broilers from the control group with conventional mixed feed; the broilers of experimental group were fed with mixed feed produced at the enterprise with 33 % extruded concentrated feedstuff additive. The feed additive contains 30 % of soy bean meal, 25 – of wheat, 25 – of sunflower seeds and 20 % of sludge and bone residues. The research declares average daily liveweight gain of the broilers from experimental group increased on 14.5 %; feed consumption pro 1 kilo of liveweight gain reduced on 16.5 % during the early ten days of rearing in comparison with the broilers from the control group. The researchers observed high growth of the broilers from experimental group till the end of rearing. The average body weight of broilers from control group and aged 37 days was 2.09 kilo; the broilers of the same age from experimental group weighed 2.195 kg. Applying of extruded concentrated feedstuff in mixed feed allowed increasing mortality rate of broilers from experimental group on 1.7 % in comparison with the broilers from control group. The authors suggest applying of extruded concentrated feedstuff contained non-merchantable products of poultry processing and sun-flower seeds when feeding broilers in the early age in order to increase poultry growth rate and mortality rate.
