Subjects of research: The group of karakul sheep fed in a various energetic caloric. The aim and function of investigation: In the condition of new economical trends to work out the effective technological system relying on gaining weight of male lambs separated from ewes in the same year, keeping them, intensifying system of feeding in order to decrease the capacity of lambs in meadows and as a result of which relating on getting products. The methods of investigation: zoo-tcchnical and biological Achieved results and their novelty: The high level of rapid growth and fleshiness of karakul lambs is specified with clearly outlines that beginning from 2-2,5 months to feed them with extra food based on a high energetic ration. The weight of 4-4,5 monthly lambs reach 30,5±0,26 kg. The lactation of experimental ewes is higher than the controlled ewes of the I group for 22,6 %, the II group for 23,2 %. Making up 13,3 kg of experimental group lambs’ body (I group) and 14,8 kg (II group) and 47,3 and 47,9 % getting meat, 2,25 and 2,73 % of fat collection shows the highness of meat industry than usual demands and the high efficiency of gaining weight of young karakul lambs. According to the diet-II the morphological constituents of the body’s of the II group extra fed group lambs showed that the inter-balance between the amount of flesh and bones (fleshiness coefficient) should be 0,29 units comparing to the I group lambs, 1,08 units comparing to the controlled group-mates. Beginning supplementary feeding from the 2 period of ewes’ pregnancies will increase the living function of lambs, if there was not noticed any sheer losses, this indicator would make 2,5 - 3 % in animals kept in farm circumstances, comparing to the experimental group-mates ewes’ high birth of this group was lessened for 6,4 % . Practical value: The practical value of the investigation was seen in the priority in the field of karakul sheep breeding to increase rapidly the male lambs which don’t satisfy the requirements of sheep market, to get a rational use from the energy of young organism, embedding little labour; pecuniary-technical means and finance to work out the technological system of increasing the productivity as well as profitability and efficiency of the system. Application degree and economical efficiency: The result of investigation is utilized in karakul sheep breeding plant: “Karnab ota” of Pakhtachi region of Samarkand. The net profit received from one lamb of the II group makes 27151,8 sums while the lambs of the I and controlled group makes 19167,1; 10282,6 sums, profitability level constitutes correspondingly 54,1,42,1; and 25, 01 percents. Utilizing sphere: All types of estate forms concerning with karakul sheep breeding.
