The effect of a biocidal paint as a disinfectant and disinsectant on the growth performance and blood biochemical parameters of broiler chickens

Abstract

The aim of this study was to evaluate the effects of liming and a biocidal paint, used in poultry houses as part of disinfection and disinsection procedures, on the growth performance and blood biochemical parameters of broiler chickens. It was assumed that in successive experimental runs (replicates), the active ingredients contained in the tested slow-release water-based long-lasting biocidal paint would not significantly compromise bird performance or blood biochemistry. The following performance parameters were evaluated: body weight (BW), body weight gain (BWG), mortality, the feed conversion ratio (FCR) and the European Broiler Index (EBI). Blood samples were analyzed to determine the levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyl transpeptidase (GGT), urea, cholesterol and triglycerides. It was found that broilers from group BP (biocidal paint) were characterized by better growth performance than birds from group L (liming). Long-term application of the biocidal paint had no significant negative effect on the growth performance or blood biochemical parameters of chickens. However, changes were noted in blood cholesterol and triglyceride concentrations in trials II and III, depending on the applied disinfection and disinsection method. The average values of these parameters were significantly higher in group BP in trials II and III, but the observed differences were at the significance threshold. The results of this study suggest that the innovative biocidal paint can be applied in poultry houses as an effective disinfectant and disinsectant.
