Should the Number of Inseminations Per Pregnancy or the Number of Heats Per Pregnancy in Dairy Cattle Be Preferred?
Öz
Some reproductive criteria were emphasized in this study, and it was debated which ones were more beneficial. Also, it tried to explain that the reproductive parameters discussed should have a connection and harmony. In addition, the importance of the average of days in milk (𝐷𝐼𝑀̅̅̅̅̅̅) parameter of the herd and how it affects not only the reproductive success of the herd but also the profitability of milk yield was explained in the figures. The deficiencies of the number of insemination per pregnancy (NIPP) criterion, which was the main subject of this study, in showing the reproductive success of the flock were discussed and instead, it was argued that the correct parameter was the number of estrus per pregnancy (NEPP). It was emphasized that the use of the NEPP parameter instead of NIPP eliminated the incompatibility among other parameters.

Süt Sığırlarında Gebelik Başına Tohumlama Sayısı mı Yoksa Gebelik Başına Kızgınlık Sayısı mı Tercih Edilmelidir?
Öz
Bu çalışmada bazı üreme kriterleri üzerinde durulmuş ve hangilerinin daha faydalı olduğu tartışılmıştır. Ayrıca ele alınan reprodüktif parametrelerin bir bağlantı ve uyum içerisinde olması gerektiği anlatılmaya çalışılmıştır. Ayrıca sürünün ortalama sağımda geçen gün sayısı (DIM) parametresinin önemi ve sadece sürünün üreme başarısını değil süt veriminin karlılığını da nasıl etkilediği rakamlarla anlatılmıştır. Bu çalışmanın ana konusu olan gebelik başına tohumlama sayısı (NIPP) kriterinin sürünün üreme başarısını göstermedeki eksiklikleri tartışıldı ve bunun yerine doğru parametrenin gebelik başına kızgınlık sayısı (NEPP) olduğu savunuldu. NIPP yerine NEPP parametresinin kullanılmasının diğer parametreler arasındaki uyumsuzluğu ortadan kaldırdığı vurgulanmıştır.
