VARIETY OF PHYSICOCHEMICAL CHARACTERISTICS OF RAW MILK IN EL-GHARB REGION OF MOROCCO: THE RELATION BETWEEN COMPOSITION AND CLIMATIC CONDITIONS

Starting from January 2015 until December 2016, a daily monitoring of the production of milk at three farms in the region of Gharb in Morocco, the climatic and rainfall data were taking into consideration to evaluate their effect on the physicochemical composition, the aim behind this study is to highlight the variability of the characteristics of raw milk by the seasonal climatic change, and to statistically analyze these variabilities in relation with seasons and the production conditions. The selected farms are known for their mastery of farming techniques, equipped with the new means of livestock health control. The livestock is 165 milk cows from two breed (Prim' holstein and montbeliard). The samples were collected from the farms. One litre bulk of milk were made by mixing the morning and the evening milk and stored at 5C until the measurement. The cows were milked by hand in milking boxes during feeding.
