Abstract

Thisstudy aimed toobserve the influenceof programsof cleaning and disinfecting in performanceof broilersand microbiologyof the facilities. Two experiments were conducted, both with960 chicksof one dayraised from until42 days. In thefirst experiment, thefloor wascovered withnew woodshavings. Inthesecondthe litter wasreused. The treatments were:Common: removal of organic matterand washingplant;European: removal of dry organic matter, wash with water under pressure, application ofalkaline detergent,rinsing,drying,and application oftwo disinfectants. The performance parameters werefeed intake, weight gain, finalweight, feed conversion,feasibilityand scoreproductiveefficiency. Microbiological analyzesweretotal count ofmicroorganisms, quantification ofClostridiumspp., E.Coli, Salmonellaspp. and Aspergillusspp.through suabesfloor, wall, feeders, drinkers andcurtains. Were alsocollectedsamples oflitter,feed andwater formicrobiological evaluation. Thestatistical analyzeswereperformedby the F testfor performance andKruskal- Wallis test for microbiologyboth witha significance level (p>0.05)using thecomputer programSASPROCGLM. In the first experimentthere was nostatistically significanteffectsfor performanceand microbiological analyzes. In the second experimentit was notedbetter poultry performance ofEuropeantreatmentand reduction ofmicrobialload. The cleaningand disinfectionhavepositive influenceson performanceof broilers. (AU)
