The present study was conducted to determine the feed value of different roughage sources cultivated in 186 different locations in the Western Mediterranean region of Türkiye.The materials of the study were 11 different roughage sources (Legume and Grass Forages) or their mixtures collected from the 27 districts of Antalya (8), Isparta (10) and Burdur (9) provinces representing the region.45 legume samples (alfalfa hay (37) and vetch stalk (8) ) 109 grasses samples (barley stalk (28), wheat fodder (2), wheat stalk (49), oat stalk (12) and grass hay (18);32mixture samples (barley-oat stalk (11), barley-wheat stalk (5), barley-vetch stalk (13) and vetch-oat stalk (3) ) were used for determination of their nutrient contents, feed,and energy values. The relative feed value (RFV) and the relative feed quality (RFQ) results of all roughages; vetch stalk 102.42 & 113.69, alfalfa hay 99.17 & 112.41 for legumes; among the wheats; grass hay 99.50 & 113.05, oat stalk 80.84 & 84.27, wheat fodder 78.69 & 83.83, barley stalk 67.72 & 69.45, wheat stalk 48.88 & 56.97 and mixed roughages were determined as vetch-oat stalk 100.49 & 108.18, barley-vetch stalk 92.58 & 97.14, barley-oat stalk 93.21 & 92.93and barley-wheat stalk 81.97 & 81.36. Grass hay, vetch stalk and vetch-oat stalk were determined as the third quality roughage according to the RFV.These results might have been due to the wrong harvesting time and harvests made with inappropriate equipment; serious nutrient losses occur in roughages until they reached the animal’s feed. According to RFQ; grass hay,vetch stalk and alfalfa hay should be used in feeding heifer, 12 to 18 months beef cow-calf, while vetch-oat stalk is in the class of roughage should be used in feeding of heifer and cows in dry season.Nutrient analysis of roughage samples showed that the nutritional losses could have occurred during harvesting and post harvesting transportation, attributing to wrong harvesting time, inappropriate harvesting equipment,and transportation to farms.
