Abstract

Juvenile growth rate of broiler chicken has been increased at an annual rate of 1.5 and 2.0% for males and females, respectively, in the last two decades. The best individual performances of broilers (liveweight at 49 days of age) were reached by the means of the tested bird groups in less than twenty years in international broiler tests conducted in Hungary. As a correlated response 1995 type commercial male broilers reached 6 kg liveweight in 124 days, compared to broilers of the 1980s, when 175 days were needed to attain the same body mass. Negative physiological and anatomical changes associated with the increased growth rate have been summarised and management procedures have been discussed reducing the incidence and damage caused by leg weakness, ascites and reduced heat tolerance based on published research results using fast growing modern mostly commercial broiler strains.
