Effect of algae feeding on selected qualitative indicators of milk of small ruminants
Novotná, Klára ; Stádník, Luděk (advisor)
Milk fat is one of the most important components of goat milk. Another benefit of goat milk fat is its better digestibility in comparison with cow milk, which is caused by the smaller size of lipid micelles. Goat milk fat contains more lower fatty acids (caproic, caprylic and capric), which affect the production and processing of milk and cause specific flavor of goat's milk and dairy products. In recent years, the subject of many studies the possibility of increasing the content of other health beneficial fatty acids in goat milk, such as conjugated linoleic acid (CLA) and omega-3 and omega-6 polyunsaturated fatty acids. Animal nutrition is a significant factor how to achieve these changes in the fatty acid profile of milk fat. For these purposes can be used as additives for certain species of algae which are the source of nutritionally valuable lipids with a high content of polyene fatty acids, especially omega-3 and omega-6 fatty acids. The ability to change the composition of goat mikl fat, represents an opportunity for the development of new products. Functional foods, such as milk and dairy products enriched with omega-3 and omega-6 fatty acids. The aim of this work is to determine what effect the addition of selected algae (Chlorella vulgaris and Japanochytrium sp.) On milk production and representation of the components of milk, focusing on the composition of milk fat and fatty acid profile in goat milk. Attention was paid to reduction of saturated and increase the proportion of nutritionally beneficial unsaturated fatty acids, in particular n-3 polyunsaturated fatty acids.
