Is there linkage between supernumerary teats in cattle and BTA3 markers?

M. Brka, N. Reinsch, and E. Kalm

Abstract. From 1997 to 1999 1005 new born German Holstein calves were investigated for the incidence of supernumerary teats. Age at inspection varied from 1 to 4 weeks. In total 110 affected calves (20 male and 90 female) and their 21 sires were genotyped for five chromosome 3 microsatellites. The average size of half-sib families was 5.2 ranging from 2 to 17. A non-parametric multipoint linkage analysis showed no evidence for linkage.
