Sažetak
This paper presents the research into characteristics of growth of chickens and ducklings, as well as their economical breeding in the outdoor system on a family farm in rural area. Studies have indicated that there are differences in genetic abilities of those two types of poultry. The logistic function was applied to describe the growth of chickens, and the generalized logistic function was applied in the model of growth for ducklings. It was determined that intensive growth phase of ducklings begins earlier and ends earlier (Ti =3.90 weeks ; 1820 g) than in chickens (Ti =4.90 weeks, 1790 g). The research also proved that breeding of ducklings was more economical than of chickens until the age of 56 days. Gross profit per group of ducks was 193.43 €, and per group of chickens the profi t was 62.33 €. Economy coefficient was 1.59, and 1.30, respectively, and the profit rate was 37.24% and 12.23%, respectively. Overall conclusion points out the fact that it was more profitable for agricultural farms to breed ducks than chickens in the outdoor system.
