The Factors Effect on Weaning Weight of Hair Goats in West Anatolia

Amaç: Bu çalışmada; Türk Kıl keçileri üzerine etkili çeşitli özellikler arası ilişkiler, kanonik korelasyon analizi ile araştırılmıştır. Materyal ve Metot: Çalışmanın verileri 2013-2016 yılları arasında doğan 1020 erkek ve 1011 dişi Kıl keçisi ırkı oğlaklardan elde edilmiştir. Sürü, doğum yılı, doğum tipi ve cinsiyeti birinci değişken seti (X) olarak analiz edilmiştir; doğum ağırlığı, otuz günlük ağırlık ve sütten kesimdeki ağırlıklar ise ikinci değişken seti (Y) olarak değerlendirilmiştir. Kanonik korelasyon analizi ile birinci, ikinci ve üçüncü kanonik değişken çiftleri arasındaki kanonik korelasyonlar tahmin edilmiş ve üç kanonik korelasyon da istatistiksel olarak anlamlı bulunmuştur (P <0.01).Bulgular: Doğum yılı, cinsiyet, doğum tipi değişkenleri ile v1, v2 ve v3 kanonik değişkenleri arasındaki korelasyonlar sırasıyla -0.77, 0.87 ve -0.82 bulunmuştur. Diğer yandan, doğum ağırlığı, otuz günlük ve sütten kesim ağırlığı ile w2, w2 ve w3 kanonik değişkenleri arasındaki korelasyonlar sırasıyla 0.84, -0.97 ve -0.78 bulunmuştur. Sonuç: Oğlakların canlı ağırlığının oluşumunda cinsiyet ve doğum tipi faktörlerinin belirleyici bir rol oynadığı belirlenmiştir

The Factors Effect on Weaning Weight of Hair Goats in West Anatolia

Objective:In this study; the relationships of several traits effects of Turkish Hair Goats were investigated by canonic correlation analysis. Therefore determining more effective factors on weaning weight of Hair goats are aimed.Material and Methods: The data were utilized from 1020 male and 1011 female Hair goat kids which were born in the period 2013 to 2016. The herd, year of birth, birth type and sex are analyzed as the first set of variables (X); weight at birth, weight at thirty day of age and weight at weaning age effects are analyzed as the second set of variables (Y). By performing canonical correlation analysis, canonical correlations between the first, second and third pair of canonical variates were estimated and three canonical correlation were found significant (P < 0.01).Results:The biggest correlations between year of birth, sex, birth type variables and v1, v2 and v3 canonical variates were found -0.77%, 0.87% and -0.82%, respectively. The biggest correlations between weight at birth, weight at thirty day of age and weight at weaning age and w1, w2 and w3 canonical variates were found 0.84%, -0.97% and -0.78%, respectively. As a result it has been determined that sex and birth type play an important role in the formation of the goat kid’s body weights.Conclusion:Hair goats reared in West Anatolia are slaughtered mostly at the end of the weaning. Because of this, assessment the factors effect on weaning weight are important. Canonical correlation analysis therefore is used to analyze all factors at the same time to define relationships between each other of weaning traits for hair goats.
