The main aim of this paper is to address the question of why native cattle were shifted from native breeds to cultured and cross-breed cattle from 2000 to 2010 and to examine whether milk yield played role in those shifts. In this paper, how milk yield influences cattle production is characterized by taking into account the contribution of local geographical relationships and variations. This paper is motivated by the concern that total number of native cattle has decreased most alarmingly in Turkey. Sustainable dairy farm systems are inextricably linked with high milk yield culture cattle imported from European countries. High milk yield has become the indicator that possesses the spillover effect for the development of cattle production. The high milk yield that is abused by culture cattle systems has led to a general increase in cattle production, especially in the west and middle-south of Turkey where farmers are relatively richer.

Sürdürülebilir Sığır Islahında Coğrafik Ağırlıklı Regresyon Kullanılarak Süt Verimi Rolü Analizi

Öz

Bu makalenin temel amacı 2000-2010 arasındaki dönemde, yerli sığır yetiştiriciliğinden kültür ve melez sığırlara geçişin nedenlerinin ve geçişte süt verimliliğinin rolünün olup olmadığının saptanmasıdır. Bu çalışmada süt verimliliğinin sığır üretimini nasıl etkilediği yerel coğrafi ilişkiler ve varyasyonlar dikkate alınarak karakterize edilmiştir. Türkiye’de yerli sığırların sayılarındaki belirleyici azalma, çalışmanın temel motivasyonu olmuştur. Sürdürülebilir süt çiftlik sistemleri Avrupa ülkelerinden ithal edilen ve yüksek süt verimliliği olan kültür sığırları ile sıkı ilişki içindedir. Yüksek süt verimliliği sığır üretiminin gelişmesinde ayırdedici bir yayılma etkisine sahiptir. Türkiye’nin doğusu ve batısı süt verimliliği açısından oldukça farklılık göstermiştir.  Kültür sığır yetiştiriciliği tarafından suiistimal edilmiş olan yüksek süt verimi, özelikle çiftçilerin oransal olarak daha zengin olduğu Batı ve Orta-Güney Türkiye’de sığır üretiminde genel bir artışa neden olmuştur.
