Grazing Alfalfa in the nutrition of ruminant animals has been increasing day by day. In this study, it was aimed to compare milk mineral and fatty acid levels of cows fed with Total Ration Mix (TMR) and cows fed with fresh alfalfa and commercial concentrate feed (2.7 Mcal/kg %21 crude protein). 24 Holstein cows were divided into two groups. The first group (TMR Group) was fed with TMR. TMR content involves barley, commercial concentrate feed (2.7 Mcal/kg %21 crude protein), corn silage, straw, and dry alfalfa. The second group (Aflalfa Group) was mainly fed with artificial alfalfa pasture as well as barley and commercial concentrate feed. The element and fatty acid levels of alfalfa plant samples from artificial alfalfa pasture and milk samples were determined by using Induced Coupled Plasma Mass Spectrophotometry (ICP-MS) and Gas Chromatography (GC) devices. TMR Group's milk calcium (Ca), phosphorus (P), and zinc (Zn) levels were found to be lower than cow's milk in Alfalfa Group. It was observed that while the caprylic acid (8:0) and myristic acid (14:0) levels of the Alfalfa Group were lower than the TMR Group; myristoleic acid (14:1), cis-11-eicosenoic acid (20:1n9c), gamma-linolenic acid (18:3n6), cis-8,11,14-eicosatrienoic acid (20:3n6), cis-5, 8,11,14,17-eicosapentaenoic acid (20:5n3), KLAc9t11 and KLAt10c12 fatty acid levels were high (p |
