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).
Milk production and composition were studied on (٣٠) yearlings of
improved Awassi sheep during their first lactation, from ١٩٩٧ to ١٩٩٨ at the
Faculty of Agriculture, Damascus University.
At the beginning of experiment the animals were ١٤ to ١٦,٥ months old and
their body weight was ٤١,٥ kg.
