Genetic disorders are often transmitted via autosomal recessive inheritance, which
negatively affect health, welfare, and yield traits in farm animals such as cattle. In this
study, a total of 80 animals belonging to Holstein Friesian (HF) reared in the dairy farm
of Akdeniz University were investigated in terms of Bovine Leukocyte Adhesion Deficieny
(BLAD), Deficiency of Uridine Monophosphate Synthase (DUMPS), Factor XI Deficiency
(FXID), and Complex Vertebral Malformation (CVM) via three molecular genotyping
methods such as Polymerase Chain Reaction (PCR), PCR-Restriction Fragment Length
Polymorphism (PCR-RFLP), and Allele-Sprcific PCR (AS-PCR). BLAD and DUMPS were
analysed by PCR-RFLP, while PCR and AS-PCR were utilized to investigate FXID and CVM
disorders, respectively. Based on fragment patterns on agarose gel electrophoresis,
animals were genotyped as normal, mutant, and carrier. In this study, no carrier or
mutant animals were detected for BLAD, CVM, DUMPS, and FXID diseases in HF cattle,
since these animals were previously imported from disease-free dairy farms located in
different provinces of Türkiye. Nevertheless, this population should be periodically
checked for autosomal genetic disorders, since inherited diseases may be observed in
the next generations due to causative mutations in the related genomic regions.
