The composition of goat milk in different types of farmings

Possible differences between compositions of raw goat's milk due to the types of farmings system (organic, conventional and traditional) were investigated. Farms were located in different parts of Republic of Serbia. All animals were loose housed. The capacity of the farm ranged from 50 to 750 French Alpine goats. A total of 72 bulk samples of raw milk were collected from each farm during the year. The principle of analysis of raw milk samples was in accordance to mid-infrared spectrometry and flow cytometry. The following parameters in raw Milk were analyzed: fat, protein, lactose, total solids, somatic cell count, milk urea, and contents of fatty acid: saturated, unsaturated, polyunsaturated and monounsaturated fatty acids. The fixed effect the types of farming and season (winter, spring, summer and fall) have shown a statistical significance difference (P 0.05). The Composition of milk also affected by a number of other factors such as the nutrition of dairy goats, breed and farm management. It is recommended to consider all these factors during the comparison of different farming systems. The results that showed significant differences could be used to improve the breeding technology of dairy goats, and feeding strategies as well as emphasize the importance of using pastures.
