Bu çalışmada, Kayseri ilinde yetiştirilen tesadüfî olarak seçilen 262 Holştayn inek, polimeraz zincir reaksiyonurestiriksiyon
fragment uzunluk polimorfizmi (PCR-RFLP) ile sığır lökosit bağlanma yetmezliği (BLAD) yönünden incelenmiş
ve BLAD-taşıyıcısı (BL) ve BLAD-taşıyıcısı olmayan (TL) inekler ilkine buzağılama yaşı, buzağılama aralığı ve
305 günlük süt verimi gibi bazı üretim parametreleri bakımından karşılaştırılmıştır. BLAD taşıyıcı ineklerin prevalansı %
4.58 olarak bulunmuştur. BLAD taşıyıcı ve taşıyıcı olmayan inekler arasında ilkine buzağılama yaşı ve buzağılama
aralığı parametreleri yönünden herhangi bir fark bulunmamıştır (p>0.05). Ancak, 305 günlük süt verimi BLAD taşıyıcı
ineklerde daha yüksek bulunmuştur (p<0.001). Bu nedenle, Holştayn ineklerde bu hastalığın yayılmasını engellemek
için BLAD-taşıyıcılarının belirlenmesi ve çiftleştirmelerin buna göre planlanması büyük önem taşımaktadır.

The Prevalence of BLAD and Comparison of Some Production Parameters in Carrier and Non-Carrier Holstein Cows in Kayseri Province, Turkey

Öz

In this study, randomly selected 262 Holstein cows reared in Kayseri province of Turkey were screened
with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for bovine leukocyte adhesion
deficiency (BLAD) and some production parameters such as age at first calving, calving interval and 305-day milk
production of BLAD-carrier (BL) and BLAD non-carrier (TL) cows were compared. As a result, the prevalence of BL
cows was found as 4.58%. There was not any difference between BL and TL cows for age at first calving and calving
interval parameters (p>0.05). However, 305-day milk production of BL cows was higher than that of TL cows (p<0.001).
Thus, the detection of BLAD carriers and properly planned mating are of great importance for preventing the spread of
the disease in Holstein cows.
