Broilers meat yield regarding on-floor and cage technologies implication

broilers, meat production, methods and stocking density, duration of growingAbstract
The experiment has been conducted at
the modern industrial complex with broilers meat
line of production by using two comparable poultry
houses. The first poultry house has been fitted by
floor equipment and the second one – by the cages.
The bunch of daily chickens (82300 birds) has been
divided into two groups and grown according to the
standard stocking density. The first group of birds
has been maintained on floor (16.9 birds per m2),
the second one has been kept in cages (50 birds in
each) with 1.93 m2 cage area (25.9 per m2, or
386 cm² per one bird). At 45 days of broilers
age, the first group animals live weight reached
2825±5.19 g, the second group animals live weight
gained 3037±10.53 g. There have been obtained
45,6 kg of meat from 1 m2 of poultry house area by
using on-floor technology, 108.8 kg – by using cage
technology, so that is 2,4 times more regarding the
less (by 57.7%) feed costs and the other resources.
However, the total live weight of broilers grown
in one cage exaggerated the limit by 31.8%
declared by the equipment producer. Complying
this requirement, it is impossible to obtain more
than 82.5 kg from one m2 of poultry house area
using the standard cage technology. It has been
concluded the modernization of this technology,
namely the development of a regimen for adjusting
the stocking density of broilers maintenance,
depending on their live weight, it is possible to
provide the meat production volume increase in
compliance with all the requirements.
