The samples were analyzed in the laboratory of veterinary diagnostic and food safety “Livexlab” and laboratory analysis of food and water “Labolab”. A completely randomized design was used with factorial arrangement (milking systems for locations) and the Tukey test (P≤ 0.05). Regarding the SCC determined that the samples analyzed were classified as very good for the canton Flavio Alfaro, and range from good to satisfactory for other cantons by the Technical Standards INEN: 9:2012 and that milking type used did not influence the result, not in the chromatographic analysis that the fatty acid content was considerably affected by the type of milking applied. Mostly fatty acids of short, medium and long chain had a greater presence in the milk obtained by manual milking. Research shows that poor management can help milking lipolysis where the fat globule membrane is affected by the different physical changes and mechanical factors. |
