Siyah Alaca Süt Sığırlarında Vücut Ölçülerinin Birbirlerine Oranlarının Verim Özellikleri ile İlişkisi

Çalışmada, Görüntü İşleme Metotları kullanarak Siyah Alaca süt sığırlarının vücut ölçülerinin ortaya konması, elde edilen vücut ölçülerinin birbirlerine bölünerek oranlar elde edilmesi ve bu oranların verim özellikleri ile ilişkilerinin ortaya konması amaçlanmıştır. Bu amaçla 198 büyük baş Siyah Alaca süt sığırının Sabit Nesne Video Metodu yardımıyla vücut ölçüleri tespit edilmiştir. Tespit edilen vücut ölçüleri birbirlerine bölünerek oranlar elde edilmiş ve bu oranlar ile Günlük Ortalama Süt Verimi (GOSV), Gebelik Başına Tohumlama Sayısı (GBTS), İlkine Tohumlama Yaşı (İTY) ile İlkine Buzağılama Yaşı (İBY) arasındaki ilişkileri ortaya konmuştur. Araştırmada, GOSV, GBTS, İTY ve İBY ile vücut ölçülerinden cidago yüksekliği (CY), sırt yüksekliği (SY), sağrı yüksekliği (SGY), oturak yumru yüksekliği (OYY), göğüs derinliği (GD), vücut uzunluğu (VU), gövde uzunluğu (GU), vücut alanı (VA) ve vücut çevresi (VÇ) arasındaki ilişkinin tüm laktasyon guruplarında düşük, negatif yönlü ve istatistik olarak önemli olmadığı gözlenmiştir (p>0.05). Vücut ölçülerinden elde edilen oranlar modele dahil edilerek GOSV, GBTS, İTY ve İBY’nın tahmini için oluşturulan çoklu regresyon denklemlerine ilişkin en yüksek Determinasyon Katsayısı (R2) değerlerinin GOSV için CY (0.389 (p

Relationship Between Production Characteristics and Proportion of Body Measurements of Holstein Cows

The objective of this study was to determine Holstein Cattle body measurements using digital imagingDIPM methods. The ratios were calculated by dividing each measurement by another and the relationship between the ratios and the output characteristics were evaluated. For this reason, the body measurements of the 198 heads of Holstein cattle breed dairy cows were calculated by the Set Object Video System (SOVS) process. The ratios were calculated by dividing each body measurement to another then the relationship between these ratios and the characteristics including the daily average milk yield (DAMY), the number of inseminations per calving (NIPC), the age at insemination (AFI) and the age at first calving (AFC) were evaluated. The relationship between DAMY, NIPC, AFI, AFC and body measurements were; withers height (WH), back height (BH), rump height (RH), pin bone height (PBH) ), chest depth (CD), body length (BL), trunk length (TL), body area (BA) and body perimeter (BP) was low, negative and not statistical significantly (p>0.05). The highest R2 measured for DAMY by WH (0.389 (p
