The aim of this research is to get the answer to the
question how the production system influences the growth and slaughter
characteristics of the carcass from naked neck chicken of different
varieties. Investigations were carried out on chickens of domestic breed
– naked neck of various plumage colors: white (W), black (B) and
gray (G). Chickens were reared
in an extensive system and fattening lasted 98 days. Chickens of both
sexes of autochthonous breeds, with 98 days of fattening, reached the
average body mass of 1108.93 g (W), 1080.26 g (B) and 1005.00 g (G),
which cannot be accepted as sufficient body mass for slaughtering
chickens in present conditions. Differences between mean values were
statistically significant. The black variety had the highest relative
share of breast meat (71.14%) and thighs (71.63%), and the white variety
of drumstick (66.97%). The gray variety had the highest relative share of
bones and skin of breasts, thighs and drumsticks, although differences
were not statistically significant. The greatest mass of tibia (18.4 g)
and the lowest of cross sectional cortical (14.52 mm2) was established
in the gray variety (18.40) which indicated the lowest bone strength and this was confirmed
by values of breaking force (30.25 kg).
