Practical aspects of crossbreeding are discussed
to provide guidelines for sheep producers. Serbia disposes with great natural
potentials for development of lamb
meat production. There are currently more than 10
recognized breeds of sheep in the country. Over the past 20 years, several breeds or
strains have been imported from other countries for their favorable
performance for specific traits. Crossbreeding systems use breed
diversity to increase productivity relative to purebred flocks. The objective of this paper
is to present some of the results obtained by introduction of crossbreeding systems for lamb meat production. Researches were
carried out on the Stara
Planina Mountain.
From data presented in this paper it can be seen that result of crossbreeding
Pirot pramenka, Pirot improved sheep and Merinolandschaf is increasing the body weight
of lambs at weaning. The heterosis effect
occurs only in the F1 generation of crossing, but in
the second F2 generation, it is lost. If differences
are compared between twobreed crossing and threebreed crossing we can see
that here are very significant influences by using Merinolandschaf as
therminal sire breed in the three breed crosing system.
