This study was conducted at the Deir Al-Hajar Shami Cattle Research Station, Animal Wealth Research Administration. For this purpose 12 primiparous Shami cows were used to know the influence of the milking regimes in the production performance of the cow and the composition of the produced milk. The animals were divided randomly into two equal groups. Machine milking were used at the first group in the presence of the calf, or for the machine milking without the presence of the calf at the second group. The daily production of milk was estimated weekly from every cow in both groups and at the same time milk samples were taken to estimate the percentage of the basic components of milk such as fat, protein, lactose and dry matter until the end of lactation. Data were analyzed in statistical program SAS by using variance analysis ANOVA (Mixed Model).
