Abstract
The purpose of research is to create a new intraraceal type of Karakul sheep, which would ensure a high productivity of fur leather, meat, milk. Was used a method of growing through cross-breeding of sheep of indigenous breed named Tsushca with those from Karakul classic breed of asian type. As a result was created a new type of sheep population named Moldavian Flesh Karakul, with a typical exterior for Karakul race, from which will be obtained 68,5-71,2% of fur leather of highest sorts with a large surface (1839 cm2). Body mass of adult rams is 89.0 - 98.5 kg, of sheep - 55.5 - 57.2 kg. Ewe's production of milk is 76,6-80 kg. Ewe's genotype is 12.5 - 25.0% share of blood of Tsushca breed and 87.5 - 75.0% of Asian Karakul breed. New type of Karakul sheep breed overcomes the classical Karakul breed mass body with 45.1%, milk production with 53.2% and fur leather surface with 31.3%. Mass of reformed sheep carcass after the fattening is 32.3 ± 1.0 kg, of 6 months lambs- 16.6 ± 0.3 kg. The slaughter benefit is respectively 54.8% and 47.5%.

Rezumat
Scopul cercetarilor - crearea unui tip nou intrarasial de ovine Karakul, care ar asigura o productivitate înalta de pielicele, carne, lapte. A fost utilizata metoda de crestere prin încrucisare a ovinelor de rasa indigena Tusca cu cele din rasa Karakul clasic de tip asiat. În rezultat a fost creata o populatie de ovine de tip nou Karakul Moldovenesc Corpolent, cu exteriorul tipic pentru rasa Karakul de la care se obtin 68,5-71,2 % pielicele (blanite) de sorturi superioare cu suprafata mare (1839 cm2). Masa corporala a berbecilor adulti constituie 89,0 - 98,5 kg, a oilor - 55,5 - 57,2 kg. Productia de lapte a oilor constituie 76,6-80 kg. Genotipul ovinelor consta din 12,5 - 25,0 % de cota sanguina a rasei Tusca si 87,5 - 75,0 % a rasei Karakul asiat. Tipul nou de ovine depaseste rasa Karakul clasica dupa masa corporala cu 45,1 %, dupa productia de lapte cu 53,2 %, dupa suprafata pielicelei cu 31,3%. Masa carcasei ovinelor reformate dupa îngrasare constituie 32,3 ± 1,0 kg, a berbecutilor de 6 luni - 16,6 ± 0,3 kg. Randamentul de abator, respectiv, 54,8 % si 47,5 %.
