Bu çalışma, Kırşehir İlinde yetiştirilen Akkaraman ırkı koyunlarda gebeliğin son döneminde yapılan ek yemlemenin kuzularda doğum ve çeşitli dönemlerdeki ağırlıklar üzerine etkisinin belirlenmesi amacı ile yapılmıştır. Araştırma materyalini, 580 baş Akkaraman koyunu ve bunların 2015 doğum sezonunda doğurmuş oldukları 554 baş Akkaraman kuzusu oluşturmuştur. Akkaraman koyunları iki gruba ayrılmıştır. Her iki gruba da buğday samanı gebelik süresince verilmiştir. Ek yemleme grubuna (EYG), gebeliğin son döneminde buğday samanına ek kesif yem (400 gr/hayvan) verilmiştir. Kontrol grubuna (KG) ise gebelik süresince sadece buğday samanı verilmiştir. Araştırmada kuzuların çeşitli dönem canlı ağırlıkları, yaşama güçleri ve Akkaraman koyunlarının bazı döl verim özellikleri incelenmiştir. Akkaraman koyunlarında döl verim özelliklerinden kısırlık oranı, doğum oranı, ikizlik oranı, yavru atma oranı, koç altı koyun başına kuzu sayısı ve doğuran koyun başına kuzu sayısı değerleri EYG ve KG gruplarında sırasıyla %12 ve %9, %86 ve %91, %13 ve %5, %2 ve %0, 0,96 ve 0,95, 1,12 ve 1,04 olarak bulunmuştur. Kuzularda yaşama gücü 90. gün ve 120. günde EYG ve KG gruplarında sırasıyla %84, %80 ve %91, %91 olarak tespit edilmiştir. Akkaraman kuzularının doğum, 90. ve 120. günlük yaştaki canlı ağırlık ortalamaları EYG ve KG gruplarında sırasıyla 5,82±0,06 kg, 30,94±0,44 kg, 35,91±0,09 kg ve 3,43±0,05 kg, 30,17±0,39 kg, 30,84±0,39 kg olarak tespit edilmiştir. Ek yemlemenin, cinsiyet ve doğum tipine göre, doğum ağırlığı ve 120. gün yaş ağırlığı üzerine etkisi önemli bulunmuştur. 90. gün ağırlığı bakımından ise sadece doğum tipinin etkisi çok önemli bulunmuştur. Sonuç olarak, gebeliğin son döneminde yapılan ek yemlemenin kuzuların doğum ve 120. gün ağırlıklarını artırdığı tespit edilmiştir.

Bekir Atar | Burhan Kara
In spite of the low grain yield they produce, the hulled wheat have become even more important in recent years because of their resistance to negative environmental conditions and healthy nutritional content. The research was carry out in order to comparison the yield and yield characteristics of durum (Kiziltan-91 and C-1252), hulled (Einkorn and Emmer) and bread wheat (Tir) varieties in Isparta ecological conditions in 2013-14 and 2014-15 vegetation periods. In both years, the highest grain yield was obtained in Kiziltan-91 variety (3992 and 3758 kg ha-1 respectively). The grain yield of hulled wheats in the first year (Einkorn 1269 kg ha-1, Emmer 2125 kg ha-1) was around Turkey averages. However, grain yield decreased of commercial wheat varieties due to the negative effect of high amount of rainfall in June in the second year, but considerably increased in (Einkorn 2150 kg ha-1, Emmer 2533 kg ha-1). N uptake was found to be lower in the than durum wheats. In terms of grain protein content, the highest values were obtained in Emmer variety (16.4%-15.3%).

Damla Özsayın
The aim of this study was to investigate the relationship between the amount of cow milk production and its price in Turkey in the period between 1985-2015.The Koyck model that is one of the distributed lag models was used to analyse of these data. The production of cow milk was considered as dependent variable and the price series consisting of cow milk prices and lagged price series are considered as explanatory variable in the model. According to the results of Koyck model, it was determined that the production of cow milk was affected by the prices of maximum one year retrospectively and the time required to dramatically affect to production of cow milk of the change taken place in prices of cow milk was 2.9 years. Furthermore, the increase of 1 TL in price of cow milk decreases the production of cow milk by 183372.4 tonnes. On the other hand, the increase of 1 TL in prices in the previous period decreases the production of cow milk by 137345.9 tonnes. Based on these data, it can be said that the price of cow milk composed in the free market conditions is rather efficient in determination to production amount. In conclusion, economic measures such as making of production planning, constituting of efficient marketing opportunities, price policies and giving a place to stable production can be taken against to fluctutations in the price increases.
