“…The concentrate feed costs had the largest ratio in both total production costs and total variable cost for all farm, and it was followed by roughage costs. In previous studies, the share of feed costs in the total production costs and total variable costs were calculated as 58.20% and 85.20% in Burdur province (Demircan et al, 2007), 57.05% and 71.35% in Biga province (Aktürk et al, 2010), 57.03% and 86.52% in East Mediterranean region (Yılmaz et al, 2016), 60.76% and 84.36% in Konya province (Oğuz and Yener, 2017), 49.83% and 90.36% in Eastern Anatolia region (Gençdal and Yıldırım, 2018). These results demonstrated that the ratio of feed costs in the total production costs of farms in Karacabey district was lower than those of others, and the share of feed costs in total variable costs of farms was higher than those of in Biga and in Konya provinces, but it was lower than those of in Burdur province, in East Mediterranean region and in Eastern Anatolia region.…”
