Kudrik N. Selection estimation of productive qualities and biological features of prolificacy type of Ascanian Karakul breed

The object of researches is Forming of lambskin, meat, milk and wool productivity at the animals of prolificacy type of askanian karakul breed of sheep. Purpose of researches - to carry out complex estimation of askanian pedigree type of prolificacy scrawl sheep in closed population on basic by the indexes of productivity and reproductive qualities. The methods of researches are zootechnics, morphological, biochemical, biological, statistical. Results of researches: 1. For a theory - First, on the basis of complex estimation of prolificacy scrawl sheep of askanian pedigree type of the black colouring, their high reproductive power, precocity, is exposed, and also combined to productivity: lambskin, milk, meat and wool at positive intercommunication of basic selection signs, sufficient sizes of changeability and high complex estimation of lambs of twins, that enables effectively to conduct subsequent selection-pedigree work in explored population. 2. For practice - the In the total conducted researches it is set, that the animals of prolificacy type of askanian karakul breed have the combined productivity and together with the promoted fecundity and desired lambskin qualities are characterized by the high indexes of precocity, milk and meat productivity. The sphere of the use is the economies from growing of scrawl sheep.
