Genetic Investigations Using Immuno-biochemical Markers in a Maramureş Brown Cattle Population

Abstract

The study of the genetic markers and identifying new markers involves an increasing number of research projects in the fields of genetics of immunology, biochemical genetics, molecular genetics, quantity genetics and the genetic improvement of animals. Some studies on genes frequency determining the red cells specificity and for whey hemoglobin are approached in the present report. In this way, some blood factors, most of them belonging to B system (the most complex system in cattle) have been evidenced. The lowest gene frequency was present in K factor (7%), and highest one in, O1, G’ , W and F1 (100%). In addition to basic importance on knowledge and determination of cattle population genetic structure for studied protein loci, another theme proposed to correlate hemoglobin type with some traits of economical importance: milk yield, fat and protein content, fat and protein yield. Higher performance was recorded by HbA/HbA individuals.
