Calidad físico-química y organoléptica de la leche en bovino de doble propósito en cuatro cantones de la provincia de Manabí

One of the challenges of the province of Manabi is that you do not have a sanitary toilet track milk from their farms which is to fulfill quality standards established in NTE INEN 0009 standard for raw milk. The objective of this research was to determine the physicochemical and organoleptic quality of milk in four corners of the province of Manabi. pH, acidity, density, fat, protein, total solids, reductase, ash, calcium and phosphorus were evaluated. The design was completely randomized (CRD) factorial arrangement 2x4; where the first factor relates to milking systems (Ma = manual, Me = Mechanical) The second factor to the cantons (Pedernales, El Carmen, Flavio Alfaro and Bolivar). The system of cattle production in the province of Manabi is dual purpose with 95%. The milking system is a factor influencing the physico-chemical characteristics of the milk; Taking into account that by applying a manual milking the protein content, pH and reductase averaging 3.76%, 6.73 and 3 hours are suitable and differ from those recorded in the mechanical system. However the composition of total solids (12.74%) is better in mechanical milking and localities, as a quality factor in the fat content in milk denoting the Flavio Alfaro Canton with the highest (4.03%) average. For the organoleptic assessment milking systems influence varying texture (T. Liquid / slightly viscous T.), with a scale of 3.53 due to the content of total solids present in the milking machine.
