THE INFLUENCE DENSITY OF POPULATION AND SEX OF FATTENED CHICKENS ON THE KALO IN THE TRANSPORT AND RANDMAN OF SLOUGHTERED

The primary objective of this study was to investigate the influence of population density and sex of chickens on transport kalo and slaughter yield chicken hybrids Cobb 500. The study was carried out on 225 day-old chicks Cobb 500, which were placed in 3-square-foot boxed cubicles with five different population density. The control group (K₀) was populated in a density of 15 chickens / m² which is a technological standard, and the experimental groups K₁ , K₂ , K₃ and K₄ were populated with density of 13 chickens / m², 14 chickens / m², 16 chickens / m² and 17 chickens / m² of floor pads. When choosing chickens, it was considered that the chickens of the experimental groups were approximately the same mass. Selected chicken specimens of the same sex ratio 50:50 (ten male and ten female) were scattered with rings, with the number of records attached to their legs. The rings are made of modified plastic resistant to water and high temperature, avoiding the possibility of damage to the numbers and the determination of the number of sample chickens. Before slaughter, chickens were rehearsed for the purpose of determining the kalo in the carriage, after which they were chained to, a chain conveyor, thus commencing the slaughter process. After slaughtering, we tested the slaughter of slaughtered chickens for the purpose of establishing the randman slaughter. Nutrition and environmental conditions were the same for all chickens. For the purpose of questioning the production parameters after a completed 42-day fattening period, 10 male and 10 female chicks of each sample group were selected by the random sample method. The data were analyzed by statistical program SPSS 15.0 (SPSS Inc., Chicago, IL, USA).
