Lojistik regresyon analizi ikili veya çoklu kategorik
yapıdaki bağımlı değişkenin bağımsız değişkenlerle neden sonuç ilişkisini
belirlemede yararlanılan bir yöntemdir. Bu çalışmada buzağı ölü doğum oranları
üzerine buzağı cinsiyeti, laktasyon sırası ve buzağılama yıl-mevsim etkileri
ikili lojistik regresyon analizi ile incelenmiştir. Çalışmanın materyali ABD
Ulusal Hayvan Yetiştiricileri Birliği’ne kayıtlı 2003-2005 yılları arasında
yetiştirilen toplam 404460 adet tek doğan buzağının doğum kayıtlarıdır. Analiz
sonuçlarına göre buzağı cinsiyeti, laktasyon sırası ve buzağılama yıl-mevsim
değişkenlerinin buzağı ölü doğumlarına etkileri önemli (P<0.05) bulunmuştur.
Hosmer-Lemeshow uyum iyiliği testi ile modelin iyi uyum gösterdiği
belirlenmiştir (P>0.12). Tüm değişkenler aynı modelde birlikte analiz
edildiğinde, dişilerdeki ölü doğum oranının erkeklere göre 1.03 kat daha fazla
olduğu belirlenmiştir. Ayrıca, laktasyon sırasının artmasıyla ölü doğum
oranının azaldığı saptanmıştır. Diğer yandan, yaz doğumlarındaki ölü doğum
oranı kış doğumlarından fazla bulunmuştur. Ülkemizde ölü doğum oranına ilişkin
kayıtlar toplanmalı ve bu oran üzerine etkili olabilecek risk faktörleri
belirlenmeli ve böylece buzağı ölümleri kontrol altına alınabilmelidir.

Logistic regression analysis is a
method to determine the reason-result relationship of independent variable(s)
with dependent variable, which has binary or multiple categorical structures.
In this study, sex of calf, parity and calving year-season effects on
stillbirth were analyzed with binary logistic regression analysis. Study
material was obtained from the USA National Association of Animal Breeders
collected among 2003-2005 with a total of 404460 birth records of single born
calves. According to the results, sex of calf, parity and calving year-season
effects on stillbirth were found statistically significant (P<0.05). The
model showed good fit, based on Hosmer-Lemeshow goodness of fit statistics
(P>0.12). When all variables were analyzed together in the same model,
stillbirth rate of female calves compared to male calves was found to be more
than 1.03 times higher. In addition, risk of stillbirth was decreased by
increasing parity. On the other hand, the risk of stillbirth in summer calves
was found to be higher than winter calves. In our country, data sets on
stillbirth rates should be collected and risk factors that have an effect on
stillbirth must be detected and then calf deaths could be controlled here, too.
