Objective: The aim of this study was to investigate the availability of quinoa, chia, teff, mung bean, andbuckwheat as an alternative feed in ruminant nutrition.Material and Methods: The materials were composed of quinoa (white, black, red), chia (white,black), teff, mung beans and buckwheat, which have passed their shelf life due to tear or damage intheir package. Fatty acid components as well as enzyme soluble organic matter (ESOM) under in vitroconditions were also determined in addition to crude nutrient contents. Metabolic energy (ME), usingthe obtained data, was also calculated.Results: It was found out that the crude protein (CP) contents were 14.04-15.38% in quinoa, 19.90-21.73% in chia, 11.98% in teff, 25.20% in mung bean, and 13.72% in buckwheat. Ether extract (EE)contents; however, were found out to be 7.13-7.97%, 30.84-35.75%, 2.46, % 3.48%, and 5.25%. Thehighest amount of linoleic acid was found in chia (60.71-66.17%). ESOM contents was determined athigh level in white quinoa, mung bean, and buckwheat. However, in vitro ME contents were found atthe highest level in chia.Conclusion: Quinoa has the potential to be an alternative to traditional cereals during early lactationperiod in ruminant animals, in which energy need is at its highest level, or as a source of energy infattening period. Chia has a high potential to be effective in preventing heat stress, especially in dairycattle. The high linolenic acid content of chia oil may allow the milk fat to be enriched by conjugatedlinoleic acid (CLA), one of the polyunsaturated fatty acids. It has been determined that teff andbuckwheat can be alternatives to other cereals, whereas mung bean, due to its crude protein beinghigh and being rich in minerals is a significant alternative for feed producers who have been in searchof new sources of protein recently
