Abstract

BOIKOVSKI, St., M. BAULOV and D. DIMITROV, 2000. Genetic characteristic of sheep with different degree of blood from Australian Merino and Boroola breed. Bulg. J. Agric. Sci., 6: 93-98

As a result of the study, regarding the allele frecuency of the stydied loci, there has been established that the sheep bearing new components of heritability from Australian merino and Boroola breed have differed from one another as well as from the basic population.
The use of rams with different degree of blood from Boroola breed for increasing the fertility and from Australian Merino for increasing the average clip of clean fibre of the basic sheep population has been accompanied by changes in the formed genetic structures of the crosses.

Key words: genetic characteristic, sheep, Boroola breed, Australian merino
