A B S T R A C T The main objective of this study were to identify the chemical composition of cow ' s milk produced in Menofiya governorate and determine the effect of seasonal variation on the main components of raw cow ' s milk along a year in Egypt with special database for Menofiya raw cow ' s milk composition . A total of 100 random cow milk samples were collected from different farms and supermarkets in Menofaya governorate during different seasons [ winter - spring - summer and autumn ] . Our results showed that the mean values of fat , T . S . , protein , and moisture in winter for cow ' s milk were 3 . 6 ± 0 . 055 , 12 . 4 ± 0 . 071 , 3 . 5 ± 0 . 046 and 85 . 5 ± 0 . 075 , respectively , and in summer were 3 . 1 ± 0 . 058 , 11 . 1 ±0 . 092 , 3 . 1 ±0 . 060 and 88 . 8±0 . 092 , respectively . From this study we concluded that the major components of milk (moisture , fat , protein and total solids) are affected by seasonal changes .
