the process of collecting milk samples and recording milk weights. Sometimes called "test day".

See translations


the application to milk of a heat treatment of a lower intensity than pasteurization that aims at reducing the number of microorganisms. A general reduction of log 3–4 can be expected. Micro-organisms surviving will be heat-stressed and become more vulnerable to subsequent microbiological control measures. (Codex Alimentarius)

application au lait d’un traitement thermique d’intensité moindre que la pasteurisation dans le but de réduire le nombre de micro-organismes. Une réduction globale de log 3 ou 4 est probable. Les micro-organismes restants subiront un stress thermique qui les rendra plus vulnérables aux mesures de maîtrise microbiologiques ultérieures. (Codex Alimentarius)


aplicación a la leche de un tratamiento térmico de intensidad más baja que la de la pasteurización con objeto de reducir la cantidad de microorganismos. En general, se puede esperar una reducción de logaritmo 3-4. Los microorganismos que sobrevivan se verán afectados por el calor y se volverán más vulnerables a las medidas de control microbiológico posteriores. (Codex Alimentarius)
