Relationships between the Polymorphism of Blood Proteins and Some Reproduction Traits in Norduz Goats

The aim of this study was to determine the influences of polymorph systems such as hemoglobin and transferrin types on some the reproduction traits in Norduz goats. The material of this study consisted of 65 Norduz goats. The polymorphism of hemoglobin and transferrin phenotypes of Norduz goats were determined. Blood proteins were analyzed through horizontal starch gel electrophoresis. It was found that the hemoglobin and transferrin types were controlled by two allel genes (HbA and HbB; TfA and TfB) in the goats. The phenotypes of HbAA, HbBB and HbAB; TfAA, TfBB and TfAB were observed in the population. Hemoglobin and transferrin gene frequencies were 0.73 for HbA and 0.27 for HbB; 0.80 for TfA and 0.20 for TfB. Hemoglobin and transferrin genotype percentage frequencies were 51% for HbAA, 4% for HbBB and 45% for HbAB; 65% for TfAA, 4% for TfBB and 31% for TfAB. According to the analyses of variance, the influences of hemoglobin and transferrin types on the gestation efficiency were not significant. However, the highest gestation efficiencies were obtained from HbBB and TfBB types with the averages of 16.05±1.75 and 13.67±3.51 kg, whereas the lowest gestation efficiencies were obtained from HbAB and TfAB types with the averages of 9.94±0.82 and 9.67±0.60 kg, respectively. In conclusion, there were polymorphism in hemoglobin and transferrin types in
