Analysis of the relationships between POU1F1 gene and genetic indexes for milk production in Italian Friesian cows - The POU1F1 has been suggested as candidate gene for genetic variability in milk production traits and some Authors reported relationships with milk, protein and fat production in Friesian breed. This work was aimed to verify if these relationships were detectable in a herd of Italian Friesian cows. The polymorphism of the POU1F1 gene was analysed in 111 cows by PCR-RFLP and correlated to the genetic indexes for milk yield, protein (kg and %), fat (kg and %), ICM, ILQ and ILQM. Significant differences among genotypes were observed only for ICM, with the AA genotype associated to the lowest value.

Abstract

Analysis of the relationships between POU1F1 gene and genetic indexes for milk production in Italian Friesian cows - The POU1F1 has been suggested as candidate gene for genetic variability in milk production traits and some Authors reported relationships with milk, protein and fat production in Friesian breed. This work was aimed to verify if these relationships were detectable in a herd of Italian Friesian cows. The polymorphism of the POU1F1 gene was analysed in 111 cows by PCR-RFLP and correlated to the genetic indexes for milk yield, protein (kg and %), fat (kg and %), ICM, ILQ and ILQM. Significant differences among genotypes were observed only for ICM, with the AA genotype associated to the lowest value.
