AVALIAÇÃO DA QUALIDADE FÍSICO QUÍMICA E MICROBIOLÓGICA DE RAÇÕES PARA CÃES ADULTOS

Abstract

Brazilian legislation guarantees minimum levels of nutrients for animal feed. The information on the labels is used to show the amounts and guarantees of nutrients in that feed formula. It is necessary that the values declared on the labeling are as accurate as possible. This work aimed to evaluate the physicochemical and microbiological quality of Premium food for adult dogs of different commercial brands in the city of Goianésia. Physicochemical analyzes were performed to determine the dry matter (DM), mineral matter (MM) or ash, moisture and pH levels. Comparisons were made of the values declared by the manufacturers (VD); with the values observed by the analyzes (VO). The results of the laboratory analyzes were compared with the minimum and maximum values allowed by the Ministry of Agriculture of Brazil, Livestock and Supply (MAPA). The results obtained were submitted to ANOVA analysis of variance and the Tukey test at the 5% level to verify the interaction between the means. It is concluded that the microbiological analysis of all diets tested negative for total coliforms and thermotolerant coliforms. The pH results indicated an average of 5.72, with sample A showing the highest value (6.30) followed by samples B (5.49) and sample C (5.47). For the moisture content, sample B (8.36%) showed higher values, differing statistically from samples A (7.50%) and C (7.33%). In the evaluation of Mineral Matter, sample A (8.33%), obtained a higher value, compared to samples B (7.34%) and C (7.44%). In the dry matter content, it was observed that samples A (92.67%) and C (92.50%) do not differ statistically from each other. Physico-chemical analysis showed that the rations were in accordance with the legislation. This ensures that the premium dry food for adult dogs sold in the city of Goianésia is of good quality.
