Conteúdo: | The objective of the present study was to evaluate the effects of hemoglobin and carbonic anhydrase phenotype on reproductive, productive and heat tolerance traits in a herd of Pitangueiras dairy cattle. Electrophoresis showed the occurrence of four hemoglobin phenotypes, i.e., A, AB and AC. The alelle frequencies for this system were 91.85%, 7.89%and 0.26% for alelles HBA, HBB and HBC, respectively. The phenotypes observed for the carbonic anhydrase system were S, FS, F, SZ and FZ, with alelle frequencies of 81.83%, 12.84% and 5.33% for CAS, CAF and CAZrespectively. The chi-square test showed that this herd is in Castle-Hardt-Weinberg equilibrium for the hemoglobin and carbonic anhydrase systems. The different phenotypes had no significant effect on reproduction, production or heat tolerance.
