    The objective of this work was to determine the evolution of contamination in the halls of broiler chicken growth, given its implication on survival.
    The degree of contamination was assessed in terms of microbiological parameters, determined by the Surface: the genus Staphylococcus bacteria, coliform, bacteria from the Enterobacteriaceae family, total plate count, total fungi.
    Samples were taken from several points of the hall, the first time at the age of 9 days chickens, then 21 days and 35 days later.
    They performed laboratory analyzes specific in accordance with the methods in operation which is performed in specialized laboratories, strictly respecting labor standards.
    The data obtained revealed that the highest degree of contamination was performed at 35 days. At the age of 9 days 3% of samples were positive for target drinkers, and 35 days were 36 % positive samples; objective feeders, 2% of samples were positive at 9 days and 35 days were 27 % positive samples; objective feed hopper, 9 days was 3 % positive samples, while at 35 days the percentage of positive samples reached 14 %; for hall walls objective, there were 2% positive samples at 9 days and 15 % of positive samples at the age of 35 days.
    The conclusion of our research was that the degree of contamination of warehouse populated with old broiler chickens significantly increase the advance in their age, all parameters analyzed microbiological having higher values towards the end of growth.
