Abstract

Objective: The objective of this study was to estimate the lactation curves of Saanen goats by using individual milk yields in the early, mid and 0-6 months periods of lactation. For this purpose, Wood’s lactation curve was used to estimate lactation yields. Material and Methods: Milk yields of Saanen goats in different periods of lactation were estimated. For this purpose, the Wood’s lactation curve model was adapted to a total of 480 milk yield measured at 14-day intervals of 40 Saanen goats. Milk yields of goats in the first three months of lactation in January-March, mid-lactation in April-June, and 0-6 months in January-June were estimated. Results: According to the harmony of Wood's model, the determination of coefficient values of the estimations of milk yields in the first, mid-lactation and 0-6 months of lactation are 0.84, 0.87 and 0.84, respectively. The root mean square errors of Wood's model are 0.91 for the first period of lactation, 0.81 for the mid-lactation period and 0.30 for the from 0 to 6 months of lactation period. Conclusions: According to the results obtained in this study, Wood's model was found sufficient to define the lactation curve in Saanen goats. However, it would be beneficial to conduct similar studies with larger herds and yield records.

Özet

Amaç: Çalışmada Saanen keçilerinin laktasyonun erken, orta ve 0-6 aylık dönemlerindeki bireysel süt verimleri kullanılarak laktasyon eğrileri tahmin edilmiştir. Bu amaçla, laktasyon verimlerini tahmin etmek için Wood modeli kullanılmıştır. Materyal ve Yöntem: Saanen keçilerinin laktasyonun farklı dönemlerindeki süt verimleri tahminlenmiştir. Bu amaçla 40 baş Saanen keçisinin 14 günlük aralıklı ölçülen toplam 480 adet süt verim ölçümüne Wood laktasyon eğrisi modelinin uyumu yapılmıştır. Keçilerin Ocak-Mart aylarındaki laktasyonun ilk üç aylık dönemi, Nisan-Haziran aylarına ait orta dönemi ve 0-6 aylar arası süt verimleri tahminlenmiştir. Araştırma Bulguları: Wood modelinin uyumuna göre laktasyonun ilk, orta ve 0-6 aylık dönemlerindeki süt verimlerinin tahminlerine ait belirleme katsayısı değerleri sırasıyla; 0.84, 0.87 ve 0.84 olarak bulunmuştur. Wood modeline ait hata kareler ortalamasının karekök değerleri ise laktasyonun ilk dönemi için 0.91; orta dönemi için 0.81 ve 0-6 aylık laktasyon dönemi için ise 0.30 olarak bulunmuştur. Sonuç: Wood modelinin Saanen keçilerinde laktasyon eğrisini tanımlamada yeterli olduğu söylenebilir. Ancak buna benzer çalışmaların daha büyük sürü ve verim kayıtları ile yapılmasında yarar vardır.
