Estudo exploratório do desempenho zootécnico de duas linhagens de frango de corte à campo

Abstract

This work was prepared from the indexes of 29 batches of pullets cutting Cobb and 27 pullets cutting Ross within the Southwestern region of Paraná, having as main objective the study of the field performance of different strains of chickens cut under the same breeding system, correlated with the time of lodging the birds. The method of analysis was an exploratory, using individual values and average performance for mortality, feed conversion and ADG (Average Daily Gain), based on the reference values of the manual creation of each strain. This study showed that there is no apparent influence of the variables studied in the different months of the year, proving that there are many other factors to be considered for the study variables beyond the breeding season. A difference was found in the results field will reference values of the studied strains, but requires a study with more reps and statistical analysis to prove the differentiation. The only variable that showed average results among the different strains was higher mortality for Cobb regarding Ross.
