Sažetak
This research was carried out on 115 Ross 208 female broilers. Data on live weights were collected from 91 broilers during 7 weeks of fattening which was the basis for modelling the growth curve using asymmetric S-function. The same function was used for modelling growth of Ross 208 female broilers on the basis of data obtained from technological procedure. The parameters of the model was established as well as the stages of growth and inflection point. By the model, 99.924 percent and 99.954 percent of variance was explained for live weights of female broilers from experiment and from technological procedure, respectively. This means that asymmetric S-function can be used as the model for description of broilers’ growth. Using this function it was possible to predict the future weights of boilers. It is also possible to predict the time in which broilers reach certain live weight. The birds from experiment would cease useful growth at weeks. Other 24 Ross 208 female broilers were slaughtered when they reached determined weights from 2200 to 3400 g in the period from 7th to 12th week. The data obtained by dissection of those broilers on the main parts (breast, thighs with drumstick, wings and back) were used for the analysis of relative growth by allometric equation. Growth rates (b) for the most valuable parts and abdominal fat were: breast - 1.158; thighs with drumstick - 0.869; wings - 0.725; back - 1.063 and fat - 1.519. Allometric coefficients indicate that only fat production was intensive in the studied period. This confirms the conclusion that the best age for the slaughter of broilers is that established by asymmetric S-function.
