This study was carried out in the central county of Ağrı Province in order to reveal the cattle feeding habits of cattle breeders. For this purpose, data were obtained by conducting a face-to-face survey with 400 dairy cattle owners of the enterprises in the county. According to the results obtained from this study, it was determined that 91.5% of the breeders produced their forage crops. It was also found out that barley, alfalfa, and sainfoin were the most produced plants in these enterprises. However, the production of the corn silage, which is an important source of roughage for dairy cattle, was performed at a very low level (1.2%). Dry hay (93.5%) took first place among the roughage sources used in these enterprises, and it was followed by alfalfa hay (61.5%) and wheat-barley straw (28.0%). Corn silage was used at a low level (7.8%) in the cattle enterprises. It was determined that cattle breeders in the central county of Ağrı province were deficient in terms of some information about cattle feeding practices. It was also demonstrated that it was necessary to increase the usage and production of corn silage as forage crops and to implement rational animal feeding practices in place of the old traditional animal feeding habits. Therefore, cattle breeders in the central county of Ağrı province should be involved in technical training programs about the cattle feeding and forage planting. As result of the courses given to the cattle breeders, their technical information about cattle nutrition and preparation of ration would be updated. For this purpose, it is also recommended that agricultural extension service should be boosted to increase the education level and awareness of the cattle breeders in the rural areas.

ÖZ: Bu çalışmanın amacı, Şanlıurfa ili merkez Eyyubiye ilçesindeki sığırcılık işletmelerinde sığır besleme uygulamaları, bu amaçla kullanılan yemler ve yemleme yöntemleri ile işletme büyüklükleri arasındaki ilişkilerin ortaya konularak, ilgili sorunları ve çözüm önerileri belirlemektir. Bu amaçla şansa bağlı olarak seçilmiş 135 sığır yetiştiricisiyle yüz yüze anket yapılarak elde edilen veriler, Ki-kare Bağımsızlık testi ve frekans analiz metodu kullanılarak analiz edilmiştir. Elde edilen bulgulara göre, araştırma kapsamındaki işletmelerin %40,2'sinde yem bitkisi yetiştiriciliği yapılırken, %59,8'in de ise yapılmadığı saptanmıştır. İşletmelerin büyüklüğü ile yem bitkisi üretimi yapmaları arasında önemli (P
