Meat quality and slaughter indices of sheep depend primarily on breed peculiarities and are connected with age, fatness, sex, feeding and keeping conditions. According to the pre-slaughter mass, slaughter mass and mass of paired carcass, crossbred animals exceed their pure-bred counterparts. Experimental work was сonducted at Terra Rich LLC in the Pologivskyi district of Zaporizhia region. Tupping rams (Rom) and Hisar (H) were used on ewes of the Romanivska breed. Two groups of cowslip were formed: a control from purebred animals of the Romanivska breed (Rm × Rm) and experimental crossbreed with Hisar (Rm × H). Control slaughter of young rams was performed in accordance with the method of estimating the slaughtering performance (meet productivity) of sheep at 8 months of age. The morphological composition of the carcasses was determined by the results of the deboned half-carcass after 24-hour cooling to determine the dressing percentage of pulp, bones and fat. The chemical composition was determined in the average meat sample, in the longest muscle of the back (mus. longissimus dorsi) the amount of intramuscular fat was determined with the subsequent caloricity count of the meat. Crossbreed animals had higher indices of productivity than the pure-bred born in the same year of the Romanivska breed. The pre-slaughter live weight of crossbreed animals was greater by 29.2 %; slaughter weight – by39.7 %. Dressing percentage of the crossbreed animals was 47.4 %, and in pure-breds – 43.8 %. The crossbreed animals had absolute preference of varietal cuts: meat of the first сlass – 94.57 %, of the second – 5.43 %, in purebreds – 91.60 and 8.40 %, respectively. The preference for purebred Romanivska sheep on the caloricity of the muscle tissue was 8.7 %. In carcasses of crossbreed young animals, the relative mass of muscle tissue was 78.8 %, bones – 21.2%, versus 73.3% and 26.7 %, respectively, in purebred counterparts. The pulpiness ratio for crossbreed young rams was 3.7 and for purebred young rams was only 2.7. The positive effect of crossbreeding on the meat productivity of young animals has been established. Crossing the ewes of the Romanivska breed with the tupping rams of the Hisar breed can be successfully used in commercial sheep raisings.

Sheepskin is a component of two important elements -leather fabric and wool. At all stages -from skinning to the production of semi-finished products, the main task is to preserve the sheepskin's natural qualities and the bond strength of wool with leather fabric. The aim of the research was to study the qualitative indicators of Romanov sheep's and crossbreed's sheepskin obtained by crossing Romanov sheep ewes with rams of Gissar breed. The effectiveness of crossbreeding in terms of sheepskin performance and its physical and technical properties was established. By the mass of sheepskin raw materials, crossbreed lambs were dominated over Romanov purebred peers by 10.9%. These differences were associated with different live weights of experimental young sheep. By the area of sheepskins, crossbreed young growth exceeded purebred peers by 9.8%. These sheepskins have a coarser coat and were characterized by the powerful development of the dermis pilar and reticular layers, which is associated with the breed characteristics of these structures. The dermis thickness in experimental sheep was in the range of 1.1-1.3 mm. Sheepskin of the Romanov breed sheep, due to its preserving and further processing, were reduced by 21.3%, which was 2.9% more compared to the experimental group. This feature is associated with the histological structure of dermal structures in experimental young animals. An indicator that characterizes the relative lightweight of the produced sheepskin is the mass of the semi-finished product (dm 2 ). According to these data, crossbreed young sheep were dominated over purebred peers by 25.6%, and it indicated their compliance with standards, according to current requirements in the fur industry. And according to the physical and technical properties, crossbreed sheepskin was dominated over pure-bred young sheep's in terms of raw materials and semi-finished products, and in terms of wool yield-to-launch ratio, by 2.6%. However, studies indicated that the sheepskin of experimental genotypes met the requirements for raw materials of existing processing industry standards.
