Oleik ve Linoleik Tip Aspir Tohumlarının (Carthamus tinctorius L.) Ruminant Beslemede Kullanımı ve Etkileri

In this review, the effects of linoleic and oleic types of safflower (Carthamus tinctorius L .) seeds in animal feeding were evaluated. Safflower is an important agricultural product that has the potential to be used in alternative/complementary medicine, food and some industrial areas in terms of its seed oil contents and quality. In addition, due to the use of safflower in animal diet as herbage, silage, residues, seeds, by-product after harvest, it provides safflower the feature of an animal feed. In recent studies, it is noteworthy that researches have increased on the positive or negative effects of the feed fatty acids profile (oleic or linoleic acids, etc.) on the yield and body characteristics of animals and the results of these reflections on animal products and human health. The fat content of the safflower plant is generally in the range of 20-45% depending on the varieties and there are linoleic (omega-6) and oleic (omega-9) types depending on the predominance of the fatty acid types. Based on the studies, it has shown that feeding of full-fat safflower seeds can create changes in both milk and meat fatty acid profiles of animals and especially increased levels of unsaturated fatty acid types. In addition, it has been determined that feeding safflower seed with high oleic content increases the milk fat content and feeding safflower seed with high linoleic content increases the amount of conjugated linoleic acids (CLA) in animal products. Thus, it is considered that a positive improvement can be seen in the health of people who consume such products based on the results of the studies.
