The profitability of broiler chicken production depends on many interrelated factors, such as the size of the farm, farming system, the genetic potential, feed price and the quality of chicken meat obtained as a final product, e.g., meat, and a strategy of their sales on the domestic and foreign market. Economic analysis were conducted in randomly selected farms growing commercial broilers, from April 2008 to March 2013 (28 cycles all together), at the same time in three buildings, with 46 thousands to 54 thousands one-day chickens. In the analyzed period, broilers were reared for 35-50 d. The average slaughter body mass ranged from 2.36 kg to 2.99 kg with feed conversion ratio (FCR) 1.68 kg of feed/kg of body weight gain to 1.78 kg of feed/kg of body weight gain. Stock mortality at that time ranged from 3.5% to 6.4%. On the basis of macroeconomic data, a clear relationship between the increase in the period particularly from 2004 onwards, prices of feed 33.6% and the purchase price of livestock 22.5% in the case of the evaluated farms were found. These values were 27.9% and 31.7%, respectively. From the analysis of the relationship between different types of broiler production costs, it was concluded that the main determinant of the profitability of live poultry production was the cost of feed and first of all was the prices of feed. This means that the boom in live poultry production is variable, resulting in consequences for production and income. 展开更多
