1/29 Translocation Test

The 1/29 translocation is a heritable chromosome abnormality that has been detected worldwide in numerous breeds of Bos taurus cattle.

Extensive studies have shown that the 1/29 translocation causes an approximate 10% reduction in fertility. This reduction results in higher return to service rates, increased calving interval and higher culling rates. Karyotype screening and selective breeding of normal cattle has led to a reduction in the incidence of this abnormality while increasing overall fertility of the breed. Diagnosis by karyotyping is an effective means of identifying carriers of this abnormality. A specific procedure has been developed to identify this condition.
