Abstract

The genetic diversity of a single nucleotide polymorphism (SNP) at the exon 20 (T945M) of the leptin receptor gene (LEPR) and of three short tandem repeats (STRs BM7225, BMS694, and BMS2145) linked to LEPR was investigated in three beef cattle herds (Brangus Ibagé, Charolais, and Aberdeen Angus). A ...

Abstract

In the detection phase of a bovine marker assisted selection programme, this paper investigated the genetic variability of three microsatellites on the chromosome 18 (BTA 18). The possible associations between genotypes or alleles of these markers versus weight at first calving and a lifetime...

Abstract

In cattle, genetic markers at the leptin (LEP) gene and at those linked to the gene have been described as affecting calving interval (markers LEPSau3AI and IDVGA51), or daily weight gain (BMS1074 and BM1500). This work investigated the effect of these alleles on LEP mRNA levels in cattle...

Abstract

The influence of cytoplasmic inheritance on reproductive traits was investigated in the Brangus-Ibagé cattle (3/8 Nelore × 5/8 Aberdeen Angus). Production records of 1577 cows born between 1953 and 1996 were analysed. Additive genetic effects were responsible for 12±11% of phenotypic variation...
