This study aimed to determine the effect of milk fatty acid composition, breed, and pregnancy status on total milk fat in dairy cows. The study was conducted with a total of 400 milk samples collected form healthy Holstein and Simmental cows. Milk samples were collected for total milk fat and fatty acid analysis. To investigate the effects of milk fatty acids, breed and pregnancy status on total milk fat, multiple linear regression analysis was performed. As a result of the analysis, breed, pregnancy status, C11:0, C14:0, C18:0, C18:1 ω9 and C18:3 ω6 were found to be statistically significant (p<0.05), while the C18:3 ω3 was nearly significant (p=0.069). Also, Holstein cows, C11:0 and C18:0 were found to have a positive effect, while pregnant cows, C14:0, C18:1 ω9, C18:3 ω3, and C18:3 ω6 had a negative effect. The multiple explanatory coefficient of the regression model (R2) was 0.238. In the light of all these findings, it was thought that milk fat could be increased with different breeding protocols. Moreover, it is suggested that the regression model can be improved further by adding different variables in future studies.

Sütçü ineklerde toplam süt yağı üzerine etkisi olan yağ asitleri ve bazı fenotipik karakterlerin çoklu doğrusal regresyon ile belirlenmesi

Öz

Bu çalışma, süt ineklerinde süt yağ asitleri, ırk ve gebelik durumunun toplam süt yağına etkisini incelemeyi amaçlamıştır. Çalışma sağlıklı Holştayn ve Simental ineklerden toplanan toplam 400 adet süt örneği ile yürütülmüştür. Süt örnekleri, toplam süt yağı ve yağ asidi analizi için toplanmıştır. Süt yağ asitlerinin, ırkın ve gebelik durumunun toplam süt yağı üzerindeki etkilerini araştırmak için çoklu doğrusal regresyon analizi yapıldı. Analiz sonucunda ırk, gebelik durumu, C11:0, C14:0, C18:0, C18:1 ω9 ve C18:3 ω6 istatistiksel olarak anlamlı bulunurken (p<0,05), C18:3 ω3 neredeyse anlamlıydı (p=0,069). Ayrıca, Holştayn inekler C11:0 ve C18:0 pozitif bir etkiye sahip bulunmuşken, gebe inekler, C14:0, C18:1 ω9, C18:3 ω3 ve C18:3 ω6 negatif bir etkiye sahipti. Regresyon modelinin çoklu açıklayıcılık katsayısı (R2) 0,238'dir. Tüm bu bulgular ışığında farklı yetiştiricilik protokolleri ile süt yağının artırılabileceği düşünülmüştür. Ayrıca ileriki çalışmalarda farklı değişkenler eklenerek regresyon modelinin daha da geliştirilebileceği önerilmektedir.
