Özet

: In this study, it was aimed to investigate the saturated and unsaturated fatty acid compositions in herbage and straw of safflower (Carthamus tinctorius L. Dinçer; thornless) plant as alternative forage for ruminant. Major fatty acids in safflower herbage and safflower straw were determined as linoleic, palmitic, oleic and stearic acids. The proportions of myristic, pentadecanoic, cis-10-pentadecenoic, palmitic, palmitoleic, cis-10-pentadecenoic, α-linolenic, ciseicosatrienoic, erucic, cis-docosahexaenoic, tricosanoic and lignoceric acids in total fat acids of safflower herbage were higher than those of safflower straw (P<0.01). The proportions of margaric, stearic, elaidic, oleic, linoleic, cis-11- eicoenioic, arachidonic, cis-eicosapentaenoic and nervonic acids in total fatty acids of safflower herbage were lower than those of safflower straw (P<0.001). The proportions of saturated fatty acid (SFA), medium-chain fatty acids (MCFA), very-long-chain fatty acids (VLCFA) and w-3, and w-3/w-6 ratio for fatty acids of safflower herbage were higher than those of safflower straw (P<0.001). The proportions of unsaturated fatty acid (UFA), monounsaturated fatty acid (MUFA), polyunsaturated fatty acid (PUFA), w-6, w-9 and long-chain fatty acids (LCFA) in total fatty acids of safflower straw were higher than those of safflower herbage (P<0.001). Palmitic, stearic, oleic and linoleic acids contents as mg/ g in dry matter (DM) of safflower herbage were lower than those of safflower straw. As a result, safflower herbage and safflower straw had a rich fatty acid content in mg/g DM. The proportions and amounts of essential fatty acids in safflower straw, which have important biological activity, were higher than safflower herbage. In general, these feedstuffs stand out as rich alternative forages in w-3 and w-6 fatty acids.
