In this study, the current status of bovine and ovine breeding in the TR22 South Marmara (GM) region, the land presence of the region, forage crops cultivation in the region, roughage adequacy were evaluated and the importance of roughage in ruminant nutrition was discussed. TR22 GM region, which includes Balıkesir and Çanakkale provinces, with an area of 24 400 km2, constitutes 3.11% of Turkey's surface area, 2.13% of its population with approximately 1.8 million people, and 2.1% of agricultural areas with 792.8 thousand hectares of agricultural land. The share of the agricultural sector in the Gross Domestic National Product of Balıkesir province is 12.9%, while it is 18.1% in Çanakkale. While forage crops are planted on 29% (1.5 million decares) of the arable land of the region, green forage production is 5.6 million tons. This amount is 9% of Turkey's green forage production, and the region constitutes 8% of the area where forage crops are planted in Turkey. TR22 GM region have 765 356 head of bovine (4.2% of the Turkey) and 2 272 056 head of ovine (4.7% of Turkey). With 1 079 613 tons of raw milk production and approximately 57 thousand tons of red meat production, the region contributes 4.7% to Turkey's milk production and 4.8% to red meat production. The roughage requirement calculated according to the ruminant animal presence of the region was determined as 2.15 million tons, and the amount of dry grass obtained from forage crops and pastures in the region was determined as 1 648 908 tons. The rate of meeting the provincial needs of the roughage produced in Balıkesir was 63%, 100% in Çanakkale and 77% in the region. In livestock, profitability, sustainability and a healthy production depend on the supply of quality and cheap roughage. For this reason, it is necessary to develop projects to eliminate the roughage deficit in the TR22 GM Region, to increase the cultivation of forage crops and to improve and protect the pastures.
