GEORGIAN MEAL-AND-FUR RABBIT SPECIES AND ITS ROLE IN INCREASING THE PRODUCTION OF RABBIT BREEDING

At present there is plenty of material in zoo technical literature indicating various cases of hetaerists. It has been ascertained that its level depends on many factors. The event is well-indicated in the mixed breeds of the same direction in their evolution process, i.e. similar in the type and the character of productivity. On the other hand the effect of heterosis is always higher in the mongrels of the mixed genotypes with eminent hereditary differences, in the mixed breeds of similar genetic structure. The effect of heterosis is usually higher with the feature of low fertility than with the feature of high fertility. The considerable influence of the features of the mother species such as quality, size, reproductive abilities, adaptation to local conditions and etc. on the level of the revelation of heterosis in crossbreeding is also confirmed. The issue of paramount importance is to effect selection on heterosis. The revelation and level of heterosis is conditioned by the proper selection of animals according to their strength of constitution, health condition, age and used material, herewith, particular attention must be paid to the body weight, bearing in mind the type of body structure, constitution, health condition and etc. So the most special matter is to select species. As it is already known each breed has its own structure and wide variety of animals. Current analysis of the situation of rabbit breeding shows that opportunities for intensive usage are not fully utilized in Georgia. Aiming to increase productivity of agricultural animals with good maturity, high-priced food, increase population, rise productivity, reproductive ability, look for effective methods of breeding.
