The technical field to which the invention relates. The invention relates to agriculture, namely, to livestock, to the way the selection of parental pairs in sheep, and can be used in different types of breeding animals of any species, populations targeted by selection on the basis of individual immunogenetic characteristics of blood and morphostructural characteristics of the placenta. The level of technology There is a method to assess the compatibility of the parent form, which reflects the phenotypic characteristics and productivity of animals (see Angolano, guidelines for breeding sheep masochistic and cold areas of productivity in the Russian Federation. - M, 2000 - 41 C.). The disadvantage of this method is the low precision of the estimate of the degree of compatibility of the parent forms. There is a method of assessing the degree of compatibility of parental forms on immunogenetic parameters, namely blood group (see Ullakko, Ivekovi. Individual selection of parental pairs / Ullakko, Ivekovi // Sheep. - 1991. No. 1. - s-23). The disadvantage of this method is the low precision of the estimate of the degree of compatibility of the parent forms. The known method the selection of parental pairs in breeding pigs, including the testing is the blood group and selection, taking into account their differences in antigenic factors of blood groups, using the genotypes at all loci blood groups, and to reproduce the selected parent pairs with difference coefficient of 0.55 and above (see U.S. Pat. RU # 2160987, IPC A01K 67/02, publ. 27.12.2000,). The disadvantage of this method is that the difference between animals take into account only the loci of blood groups that do not always give an accurate assessment of the degree of compatibility of the parent forms. The closest in technical essence and the achieved positive effect and adopted by the authors for the prototype is the method of selection of parental pairs for breeding cattle, including testing for blood groups and then selection, taking into account their differences in antigenic factors of blood groups, and for reproduction pair with index antigenic similarities, not exceeding 0,250 (see U.S. Pat. RU # 2112370, IPC A01K 67/02, publ. 10.06.1998,). The disadvantage of this method is that the difference between animals take into account only the loci of blood groups that do not always give an accurate assessment of the degree of compatibility of the parent forms. Disclosure of inventions The task of the invention is to develop a method of selection of parental pairs in sheep, has a high predictive effect by establishing limits on the optimum genetic compatibility of both parents and morphostructural state is lacenterra apparatus of the parent body. The technical result that can be achieved using the present invention is to increase fertility viable, productive offspring due to selection of parental pairs with regard to their degree of genetic compatibility and use of the placenta as bischoping material. The technical result is achieved by way of the selection of parental pairs in sheep, including individual testing for blood groups of both parents and then selection taking into account the degree of their genetic differences, expressed through the index antigenic similarities in the range from 0 to 1, while additionally determine morphostructural the condition of the placenta, and selection of parental pairs to determine if the genetic compatibility of the average values of the index antigenic similarities within Ra=0,31 is 0.60 and morphostructural condition of the placenta with mass 310-330 g, the number of cotyledons 68,4-76,2 pieces, the distance between cotyledonary 20/2,5-2,7/3,0, see The method of selection of parental pairs in sheep is as follows. During breeding company form parent pairs: sheep (♂)×uterus (females) of the three variants of the breed selection: option 1 - ST×CA: sheep (♂) Stavropol rocks (ST) uterus (females) Caucasian breed (KA); option 2 - CM×CA: sheep (♂) Soviet gelding is C (CM) uterus (females) Caucasian breed (KA); option 3 - AM×MM: sheep (♂) Australian Merinos (AM) uterus (females) manicacci Merino (MM). The mares and sheep produce blood from the carotid artery in tubes with sodium citrate in the amount of 3.8% in the ratio of 1 ml of citrate: 3 ml blood. Test tubes with blood, after thorough mixing, tightly closed tube and transported to the laboratory. From each blood sample serves 8-10 ml of a 2.5% suspension of erythrocytes. Using specific reagents immunodiagnostics and 2.5% suspension of erythrocytes of investigational animal put hematological tests, the reaction of hemolysis and agglutination, the results of which determine the antigenic composition of the blood of the animal on 6 systems loci of blood groups a, b, C, M, D, and 14 erythrocytic antigens AA, AB, CB, Be, Be, Bi, Bg, Ma, Ca, Cd, Da, O. Determine the individual genetic characteristics of animals, using the formula: where Ra - index antigenic similarities; S is the number of similar antigens, we compared animals; n1- the number of identified antigens for the first animal (father); n2- the number of identified antigens from the second animal (mother). Establish the degree of genetic compatibility between the rams and the uterus, which is expressed in numeric values of the Indus the KSA antigenic similarity from 0 to 1, additionally, postpartum uterine determine morphostructural the condition of the placenta and indicators morphostructural condition of the placenta, and selection of parental pairs to determine if the genetic compatibility of the average values of the index antigenic similarities within Ra=0,31 is 0.60 and morphostructural condition of the placenta with mass 310-330 g, the number of cotyledons 68,4-76,2 pieces, the distance between cotyledonary 20/2,5-2,7/3,0, see A brief description of the drawings and other materials Figure 1 is given to the selection of parental pairs in sheep table 1, the distribution of possible variants of a combination of parental pairs depending on the size of the index antigenic similarities. Figure 2 - the same, table 2, morphostructural indicators placenta females with the value of the index antigenic similarity of parental pairs. Figure 3 - same as table 3, live weight of lambs at birth, the number of re-insemination of Queen bees, depending on the size of the index antigenic similarities. The implementation of the invention Examples of specific implementation method the selection of parental pairs in sheep. Based on the analysis of modern animal husbandry, biological information concluded priority role for the evolution of living nature, objectively existing sexual selectivity. A great value selection, under the ora is that is the only factor that can produce a new biological structures - the birth of the offspring. While the male and female elements must be different, but to a certain extent (Malakhovsky YA screening and Selection methods and breeding of agricultural animals / Alamedacounty, Ayatolah. - Omsk, 1993. - 76 S.). Genetic system of blood groups is a collection of erythrocyte antigens. The sheep know 8 genetic systems, different number of antigens and the number of the corresponding alleles. Erythrocytic factors defined by hematologic tests, the reaction of hemolysis and illuminatii inherited by Mendeleev laws, immutable throughout the life of the animal, independent of the conditions of his detention, feeding inherited by descendants codominance represent a suitable model to identify differences in the genetic compatibility of parental pairs. The degree of these differences are expressed in the value of the index antigenic affinity, high value which indicates the genetic proximity of two individuals, low genetic divergence. The degree of genetic differences from 0 to 1 are calculated according to the formula (see Assurebuy. Genetic analysis / Assurebuy. - M.: Nauka, 1970. - 342 S.). where Ra - index antigenic similarities; S - h is words of similar antigens, we compared the animals; n1- the number of identified antigens for the first animal (father); n2- the number of identified antigens from the second animal (mother).
The method of selection of parental pairs in sheep is as follows. During breeding company form parent pairs: sheep (♂)×uterus (females) of the three variants of the breed selection: option 1 - ST×CA: sheep (♂) Stavropol rocks (ST) uterus (females) Caucasian breed (KA); option 2 - CM×CA: sheep (♂) Soviet Merino (CM) uterus (females) Caucasian breed (KA); option 3 - AM×MM: sheep (♂) Australian Merinos (S) uterus (females) manicacci Merino (MM). The mares and sheep produce blood from the carotid artery in tubes with sodium citrate in the number of 3.8% in the ratio of 1 ml of citrate: 3 ml blood. Test tubes with blood, after thorough mixing, tightly closed tube and transported to the laboratory. From each blood sample serves 8-10 ml of a 2.5% suspension of erythrocytes. Using specific reagents immunodiagnostics and 2.5% suspension of erythrocytes of investigational animal put hematological tests, the reaction of hemolysis and agglutination, the results of which determine the antigenic composition of the blood of the animal on 6 systems loci of blood groups a, b, C, M, D, and 14 erythrocytic antigens AA, AB, CB, Be, Be, Bi, Bg, AF, CA, Cd, Da, O. Determine the individual genetic characteristics of animals, using the formula above, establish the degree of genetic compatibility between the rams and the uterus, which is expressed in digital index values antigenic similarity from 0 to 1. The distribution of possible variants of a combination of parental pairs depending on the size of the index antigenic similarities are shown in table 1, Fig.1. Conducted calculations indicated the distribution of possible combinations of parental pairs in three ranges of values of the index antigenic similarity (IAS): in the interval 0-0,30; 0,31-0,60; 0,61-0,90. Among the examined animals the greatest number of parental pairs were distributed in the range of EAS from 0.30 to 0.60: for parent pairs ST×KA-64,7; CM×TO the - 60.2 and AM×MM - 54,4%. During lambing ewes taking placenta immediately after its exit from ancestral ways. The placenta weighed, consider the number of cotyledons, their size, the distance between them. Based on the analysis of the magnitude of the weight of the placenta, indicators cotyledonous apparatus of ewes with different values of the index antigenic similarities, established the superiority of the studied indicators of placental females with IAS with the average of its values (0,31 to 0.60), compared with the extreme options (0-0,30 and 0.61-0,90). Morphostructural indicators placenta females considering the magnitude of the IAS parental pairs shown in table 2, figure 2. In three different parent selection analyzed the magnitude of the body weight of newborn lambs and reproductive properties females. It was determined that females with IAS within 0,31-0,60 was born a larger number of lambs on average, 21.1%, with a greater magnitude of body weight on average, 16.7%, in the period of insemination of Queen bees was almost half the cases of re-insemination, but the birth of a greater number of twins on average of 51.1%. The live weight of lambs at birth, the number of re-insemination of Queen bees is shown in table 3, figure 3. Performance tested and proven on a representative material by verifying with the nature of the structure of the placenta, as bischoping material as is the body performs a major role in the birth of viable offspring. Thus, additional definition morphostructural placenta status in the selection of parental pairs with regard to their genetic compatibility, expressed through the index antigenic similarities contributed to the improvement of the reproductive qualities of the uterus and the birth of a large, viable offspring. The present invention in comparison with the prototype and other known technical solution has the following advantages: - increase of productivity of the young, due to selection of parental pairs, with an excellent combination of genetic parameters with additional assessment morphostructural placenta status; - ability to identify the optimal combination of parental forms in the early stages of pregnancy; - provide forecast of normal pregnancy and birth of viable offspring; - significant savings of time through the use of the placenta as cheap bischoping material. The method of selection of parental pairs in sheep, including individual testing for blood groups of both parents, and then the selection taking into account the degree of their genetic differences, expressed through the index antigenic similarities in the range from 0 to 1, characterized in that it further determine morphostructural the condition of the placenta, the rich selection of parental pairs is carried out at the genetic compatibility of the average values of index antigenic similarities within Ra=0,31 is 0.60 and morphostructural condition of the placenta with mass 310-330 g, the number of cotyledons 68,4-76,2 pieces, the distance between cotyledonary 2,2/2,5-2,7/3,0 see
