Factors affecting milk freezing point from montbeliard and Prim Holstein Cows

Abstract

Data comprised 10,000 milk samples from 165 Holstein-Montbeliard cows in three geographical separated zones, geographically located in the ALGHARB region of Morocco. Milk freezing point (MFP), Temperature and precipitations were measured for a period from January 2015 to December 2016. The objective of this study was to estimate the influence of climatic parameters (temperature, precipitations), breed, month of milk sampling on the milk freezing point of Holstein-Montbeliard cows. The milk freezing points of samples were highly significantly affected by two factors: month of sampling and climatic parameters, specially temperature. MFP was lowest in milk samples taken from January to March, and those taken in summer period, highest in samples from November to December.
