Resumen : En la Sierra central ecuatoriana existen casos de inestabilidad proteica de leche cruda bovina, por lo que la empresa Tonicorp desea conocer las razones por las cuales esto ocurre...
Descripción : In the Ecuadorian central Sierra there are cases of protein instability of raw milk, so Tonicorp wants to know the reasons why this happens. Based on this unknown to be able to establish the factors that could affect at the protein instability of raw milk from cattle, 18 farms that supply milk of the Tonicorp company with different degrees of stability, located in the provinces of Tungurahua and Chimborazo, were studied. 48 factors related to the productive and zootechnical management of each of the farms were collected as study variables. By means of data collection, first of all, the farms were characterized, according to the type of management in order to observe similarities and differences between those with high, medium and low milk protein stability. The farms under study have a productive cattle management with some differences in factors such as: supply of supplements, balanced meal and mineral salts proportion, types of fertilizers, systems of entry to pastures. Besides, similarities were found in factors such as: types of grasses, percentage of protein in the balanced, frequency of use of fertilizers and irrigation systems. On the other hand, correlations were got from each factor under study with the updated and individual results of each cattle of the Ramsdell Test taken at the production plant in Guayaquil; This test determines the degree of protein stability of raw milk using tubes at boiling temperature that show a numerical stability result. As results, the following significant correlations were found: an average positive correlation in the height of the area with the results of the Ramsdell test (0.56), an average negative correlation of the feed supply in kg / day / cow with the results of the Ramsdell test (-0.44) and finally an average negative correlation between the concentration of potassium in grazing soils with the results of the Ramsdell test (-0.57), concluding that these factors could affect protein stability of raw milk. Focus on the data collected and the results obtained, a series of management recommendations were made for cattle in production in order for the milk to reduce its tendency to present protein instability.
