Management tools applied to milk quality in cattle farming in the Western Amazon

This study aimed to analyze the applicability of management tools such as SWOT matrix, GUT matrix, Brainstorming, PDCA, Ishikawa diagram, and 5W2H in improving milk quality in rural properties for family labor. The survey was conducted in 18 properties in the municipality of Senador Guiomard, State of Acre, Brazil, during the period from January to December 2019. The properties were divided into two groups (treatment group-TG and control group-CG) and the data obtained through a form with 255 questions for diagnosis and analysis (LQL-GO) for somatic cell count (SCC) and total bacterial count (TBC) were tabulated in spreadsheets (Excel (R)) and subjected to statistical analysis by the Wilcoxon test. Nineteen weaknesses were obtained through the GUT matrix. The implementation of milking practices using tools obtained an average reduction of 31.4% for SCC and 63% for TBC in TG and a reduction of 39.3% for SCC and an increase of 33.7% for TBC in CG. Thus, the management tools applied to milk quality are capable of generating positive results (p < 0.05) in microbiological control, facilitating quick decision-making, aiming at the correction of weaknesses, and, consequently, an increase in profitability.
