Efficiency of broiler chicken meat production under different raising duration

Currently, broiler chicken fattening on commercial poultry farms lasts for 37-38 days. At the same time, it is known that from the 40th to the 56th day of life, the standard indices of average daily live weight gains of broiler chickens of the Ross-308 cross are at the level of 87-100 g. The influence of different broiler chicken raising duration (38, 40, 42, 44 days) on productivity, carcass meat qualities and economic efficiency of poultry meat production on a broiler farm was studied. It was found that the best production and management indices of broiler chickens were in the 2nd trial group where the fattening period lasted for 40 days. Due to the intensive growth of broiler chickens in this group compared to the trial groups 3 and 4, feed conversion improved and, to an even greater extent, the European Efficiency Productivity Factor which is an integrated index of broiler production efficiency was by 6-9 units higher than that in other groups. The increase of the duration of broiler chicken floor management to 40 days of age contributed to improved carcass meat qualities, while slaughter yield, the weight of muscles, fillet, and yield of edible parts in carcasses increased. The profitability of production and sales of broiler chickens in the 2nd trial group was by 1.2-7.7 percentage points higher than in other groups. In order to increase the efficiency and profitability of broiler chicken meat production on the poultry operation of OOO “POZTs Svezhenka”, it is proposed to raise poultry on litter up to 40 days of age using developed and tested technological parameters including the intermittent LED lighting mode.
