Gaolao cattle

The aim of this study was to identify the Complex Vertebral Malformation (CVM) in repeat breeder and anoestrous animals in Maharashtra state region. Total 102 animals of HF crossbred, Dangi, Gaolao and Non- descript were screened from field and cattle dairy farm. CVM is a hereditary recessive disorder in Holstein cattle which have a significant economic impact on dairy cattle breeding worldwide. Fifty repeat breeder and fifty-two anoestrous animals blood DNA were extracted by traditional method. Genotyping was performed by using PCR-RFLP analysis with the help of PstI restriction enzyme.

The current research was designed to study DNA sequence variation within Signal transducer and activator of trancription 1 (STAT1) gene and to find association of STAT1 gene variants (if any) with milk traits in Gaolao cattle. DNA was isolated from around 40 Gaolao cows from farmers herd and farm in breeding tract. The STAT1 gene regions of 314 bp, 850 bp and 154 bp fragments were amplified using STAT1G1, STAT1G2 and STAT1G4 primers respectively.
