THE BREEDING OF DAIRY SHEEP BY GENETIC MARKERS ASSESTED

Abstract


The investigation involved 66 Teleorman Black Head Tsigai sheep. The animals were monitored throughout their twelve controls determining the total amount of milk. The genetic markers considered by the investigation were the haemoglobin and transferrin. They were identified two genotypes (HbA/HbB and HbB/HbB) at the haemoglobin locus and eight genotypes at the transferrin locus.  The simultaneous analysis of the two studied markers reveals the superiority of the heterozygous sheep HbA HbB/TfMTfE, which displayed the highest productive performance for the studied character.

 Key words: genetic marker, sheep, haemoblobin, transferrin
