Bu çalışma, Esmer sığırlarda linear tip özelliklerini etkileyen çevresel faktörlerin incelenmesi amacıyla yürütülmüştür. Bu amaçla, 135 sığırda 16 adet tip özelliğine ait 474 adet gözlem yapılmıştır. Araştırmada kullanılan istatistiksel modele sürü, laktasyon sırası, hakem, laktasyon dönemi, değerlendirmenin yapıldığı mevsimin etkileri dahil edildi. Ayrıca, değerlendirmenin yapıldığı dönemdeki ineğin yaşı da linear ve kuadratik kovariyet olarak modele ilave edildi. Göğüs genişliği, vücut derinliği, açısallık, arka bacak açısı, arka bacak (yandan görünüm), arka bacak (arkadan görünüm), sağrı eğimi, sağrı genişliği, ön meme bağlantısı, arkadan meme bağlantısı genişliği, arka meme bağlantısı yüksekliği, meme başı yerleşimi (arkadan görünüm), meme başı yerleşimi (yandan görünüm), meme başı uzunluğu, meme merkez bağı ve meme derinliğine ait ortalama doğrusal puanlar sırasıyla 5,5±0,1; 6,1±0,1; 5,.2±0,1; 4,7±0,1; 4,4±0,1; 4,4±0,1; 5,6±0,1; 5,0±0,1; 5,8±0,1; 5,4±0,1; 6,1±0,1; 5,1±0,1; 4,1±0,1; 5,8±0,1; 5,8±0,1; 6,6±0,1 dır. Vücut derinliği ve arkadan meme bağlantısı genişliği dışındaki bütün tip özellikleri üzerine hakemlerin etkisi önemsiz bulunmuştur. Öte yandan, sürü, laktasyon sırası, laktasyon dönemi ve değerlendirmenin yapıldığı mevsim bir çok doğrusal tip özelliklerini önemli derecede etkilemiştir. Değerlendirme sırasındaki yaşın bir çok doğrusal tip özellikleri üzerine linear ve kuadratik etkileri de önemli bulunmuştur. Doğrusal tip özellikleri arasındaki fenotipik korelasyonlar da düşükten orta dereceye kadar değişim göstermiştir.

The study was carried out to investigate the magnitude of non-genetic factors affecting linear type traits in Brown Swiss cattle. For this purpose, 474 observations for the 16 linear type traits on 135 cattle were made. Statistical model used in this research included fixed effects of herd, parity, scorer, stage of lactation, season at classification. Additionally, the age at classification was included to the model as linear and quadratic covariates. Average linear scores for chest width, body depth, angularity, foot angle, rear leg (side view), rear leg (rear view), rump angle, rump width, fore udder attachment, rear udder attachment width, rear udder attachment height, teat placement (rear view), teat placement (side view), teat length, central ligament and udder depth were 5.5±0.1, 6.1±0.1, 5.2±0.1, 4.7±0.1, 4.4±0.1, 4.4±0.1, 5.6±0.1, 5.0±0.1, 5.8±0.1, 5.4±0.1, 6.1±0.1, 5.1±0.1, 4.1±0.1, 5.8±0.1, 5.8±0.1, 6.6±0.1 respectively. Scorers did not have significant effect on all type traits except for the body depth and rear udder attachment width (P<0.01). On the other hand, herd, parity, stage of lactation as well as season at classification affected significantly most of the linear type traits. The linear and quadratic effects of age at classification on the most of linear type traits were also significant. Phenotypic correlations among the linear type traits were in low to medium range.
