Desarrollo de un Sellador Post-Ordeño con Goma Espina Corona

Abstract

To prevent infection by mastitis in cattle, it is advisable to use post milking teat dip. The objective of this study was to develop a post milking antiseptic sealant with physicochemical stability, to avoid product losses by leakage. The sealant was formulated with the espina corona gum, which increases the viscosity of the product. A central composite rotatable design was applied to obtain the optimal formulation. The apparent viscosity was evaluated as the response variable with a Brookfield DVII + LV2. The optimal formula was determined as: espina corona gum (1.7%), dematerialized water (88.60%), glycerin (4.70%), iodine solution and surfactant (3.00%) and buffer solution pH = 50.3 (2.00%). The sealant showed a rheological behavior of the pseudoplastic type. It is concluded that the espina corona gum is suitable to formulate a post milking sealant with acceptable physicochemical stability and that also keeps its active principle as a bactericide.
