Abstract
The length of broiler production cycle is also an important factor when profitability is
measured. This paper is to determine the effects of different market ages and down-time
period, overall broiler production cycle length on performance and economic parameters
based on Hungarian production and financial circumstances. A deterministic model was
constructed to manage the function-like correlations of age-related daily weight gain, daily
feed intake and daily mortality data. The results show that broiler production cycle length has
a significant effect on production and economic performance. Cycle length is determined by
the length of down-time and grow-out periods. If down-time period is reduced by one day, an
average net income of EUR 0.55 per m2 is realizable. However, the production period is not
directly proportional either with emerging costs or obtainable revenues. Profit maximization
is attainable if the production period is 41-42 days.
