Poultry meat is in the range of basic human nutrition. In human nutrition has a significant position mainly due to its composition. It is especially valuable for high-quality protein. They are very easily digested and contain all the essential amino acids. Aim of this study was a comprehensive analysis of the level of commercial properties in broiler chickens and their final hybrids. The analysis can bring about recommendations for breeders in the selection of suitable hybrid combinations in our conditions. Parental self-test forms consisted of rearing parents until the age of 154 days, the laying period of 280 days and four sub-fattening progeny tests. Rearing, laying and fattening progeny took place in the hall without windows, with deep bedding with controlled lighting and air conditioning regimen. The tests were performed 4 sub-fattening progeny tests using a load of 17.2 units chickens/1m2, length of fattening period was 35 days. The data were obtained with the consent of management of the primary data a comprehensive report of international tests and parental forms of broiler fattening sub-tests carried out in the final hybrid MTD Ústrašice for the years 1995 to 2009. These tests were made by MTD and methodology based on the guidelines for the implementation of performance tests of poultry. The data obtained were classified, summarized, and then the variation statistically using STATISTICA version 6. By comparing the results obtained from the parents and fattening tests it can be stated that, overall, the best combinations were Ross 308 and Cobb 500.
