Functional properties of the three hemoglobin phenotypes of Nelore cattle

Abstract

Blood and stripped hemoglobin from Nelore cattle individuals were submitted to oxygen equilibrium experiments in both gasometric and spectrophotometric methods. No difference was detected in oxygen affinity and Bohr effect among Hb A, Hb B and Hb AB in experiments with both blood and stripped hemoglobin, in the presence and absence of the chloride ion. However, n values (Hill plots) were higher in Hb B and Hb AB (>2) than in Hb A (<2).

Studies on the Productive Traits and Relationship between Breeds of Cattle (Friesian Bunaji Cross, Bunaji and Sokoto Gudali) Using Blood Biochemical Polymorphism

“…There exists a deficit of literature reports on the impact of Hb types on growth and production traits. However, [15] reported that haemoglobin types had no significant influence on LL. No direct evidence exists of differences among the three Hb phenotypes (AA, AB and BB) for fitness in cattle [16,17] reported that Hb type did not significantly affect milk yield and butterfat percentage in dairy cattle.…”
