Abstract
The study included a total of 127 sheep milk samples from two different areas (Livno and Travnik) in summer feeding period (July, August and September). Fatty acids in milk were determined by gas chromatography (GC). The animals were marked with the appropriate number of ear tags on the basis of which we always took samples from the same animals through different periods. Fatty acids in milk were determined by gas chromatography and the following fatty acids composition: butyric acid, caproic acid, caprylic acid, capric acid, stearic acid, oleic acid, linoleic acid, arachidonic acid, eicosapentaenoic acid, docosahexaenoic acid, rumenic acid. The fatty acid content of sheep's milk in this study showed a tendency of variation, both within and between sampling areas, and characterized by its relatively high content of saturated fatty acid (SFA) during the period of harvest.
Highlights
Milk and milk products are well balanced nutritious food in human diet
The fatty acid content of sheep's milk in this study showed a tendency of variation, both within and between sampling areas, and characterized by its relatively high content of saturated fatty acid (SFA) during the period of harvest
Sheep milk from Livno and Travnik areas contained a higher proportion of SFA compared to unsaturated fatty acids (UFA) and polyunsaturated fatty acids (PUFA)
Summary
Milk and milk products are well balanced nutritious food in human diet. The large number of research studies with the aim of increasing the biological value of animal products - the milk of ruminants, comes from the FAO recommendations, which in 2003 established the consumption of SFA for humans. Only two procedures can change the fatty acid profile of products derived from ruminants: modification of fatty acids during the processing, or change in the. Fatty acid profile of the diet (Palma Rennó et al 2013). Most studies focus primarily on the effect of feeding the sheep on the fatty acid profile (Addis et al 2005). The aim of this study is to determine the fatty acid composition of sheep's milk as well as to monitor the influence of diet on their composition
