Resumo(s)
A total of 195 bulls of eight Portuguese beef
cattle breeds (Alentejana, Arouquesa, Barros , Maronesa, Marinhoa, Mertolenga, Mirandesa and Preta) were genotyped for the GH AluI polymorphism by the polymerase chain reaction and restriction length polymorphism (PCRRFLP).
The genotype and gene frequencies for
each breed were determined and shown to be
quite variable among the breeds. The overall
gene frequencies for L and V were 0.759 and
0.241, respectively. The relation between the
bGH-AluI polymorphism and growth performances
was ascertained in 168 of the animals
analysed. According to our results there is a
significant association between the genotypes
LL and LV of the bGH and the average live
body weight of the animals of the breeds Alentejana, Marinhoa and Preta.
