Sažetak
Objectives: The aim of this study is to analyze the effects of economic losses due to diseases of hybrid heavy hens in intensive poultry production and their impact on economic production of hatching eggs. Material and methods: The study was conducted at a poultry farms in northern Croatia, where chickens are hatched and then moved and kept at a production barn from the age of 23 weeks until the end of the production cycle at the age of 56 weeks or 32 weeks of laying. In the study, the flocks were followed during the breeding phase (23 weeks) and the laying phase (33 weeks). The analysis of economic losses and costs included the technological results of each phase, the average age of dead poultry, food consumption, mortality rate, egg production as well as farm's operational dana, planned and achieved results. Damages were estimated using differential equations and a detailed analysis. ResuIts: The total costs due to diseases during the breeding phase and in the production of hatching eggs amounted to U.S. $ 33, 413.55 and U.S. $ 251, 695.25, respectively. The most common causes of death in the breeding phase were cachexia (23.56 %), necrosis of the femoral head (7.97 %) and arthritis (10.51 %). In the production of hatching eggs, the most important causes of death of hens were reproductive organs diseases (4.87 %), Marek's disease (5.04%) and costs due to liver disease (2.02 % ). Conclusion: Since the poultry production has the significant role in the agricultural and food production sectors, it is of great importance to know the effect of poultry diseases on the poultry industry and their impact on the country's economy.
