“…Each breed or animal type shows some heterogeneity in morphological, productive and technological qualities. Microsatellite loci (short tandem repeat, STR) can be used to solve breedingtasksrelatedtothedeterminationofbreedaffiliation or breed type (Deniskova et al, 2018;Isakova et al, 2019Isakova et al, , 2021Kharzinova, Zinovieva, 2020;Nosova et al, 2020;Lemesh et al, 2021).…”

“…The preservation and further improvement of the breed should be controlled by the genetic dynamics studies both in the breed as a whole and in the main breeding farms engaged in KMM breeding. We have previously shown that local breeds of farm animals (in particular, the Kyrgyz horse) are characterized withahighgeneticdiversity,butlocaldifferentiationisalso present,andthedifferencesaresignificantforanumberof high-altitude experimental zones (Isakova et al, 2021). In this regard, studies of similar structure are needed.…”

The aim was to ascertain the genetic and geographical structure of the Kyrgyz mountain merino (KMM). We analyzed DNA samples of 109 Kyrgyz mountain merino specimens, bred in three state breeding factories (STB), including“Orgochor” in the Issykul Province,“Katta-Taldyk” in the Osh Province and STb named after Luschikhin in the Talas Province. We identified 126 alleles in 12 microsatellite markers (McM042, INRA006, McM527, ETH152, CSRD247, OarFCB20, INRA172, INRA063, MAF065, MAF214, INRA005, INRA023). There were 6 to 16 alleles in each locus (mean 10.500 ± 0.957 alleles per locus). We identified 67 rare alleles (prevalence less than 5.0 %), which made up 53.2 % of all alleles found. The greatest number of rare alleles was found in STR-markers of CSRD247, INRA023, INRA005, INRA006, MAF214 and OarFCB20. For each group, there were individual differences in the distribution of allele frequencies across all the STR loci studied. The most significant of them were as follows: with regard to the McM042 locus, allele 87 was major in the TALAS and OSH groups (35.6 and 45.7 %, respectively), whereas allele 95 was major in the ISSYK-KUL group (36.2 %); allele 154 was major in all groups with regard to the INRA172 locus, but it was 1.25 times less prevalent in the ISSYK-KUL and 1.66 times less prevalent in the OSH groups compared to TALAS (55.2 and 41.4 %, respectively), whereas alleles 156 and 158 were found only in the ISSYK-KUL group. Considering the ETH152 locus, 186 allele prevalence in the TALAS group was 51.1 %, but allele 190 was also markedly prevalent in the ISSYK-KUL and OSH groups, 34.5 and 34.3 %, respectively. The genetic division of the studied groups of KMM (with K from 3 to 10) was homogeneous – the contribution of each subcluster was equivalent. The AMOVA analysis revealed that the groups are located equidistantly. To conclude, the genetic diversity of the Kyrgyz mountain merino in three state breeding factories of the Kyrgyz Republic was high and comparable with each other.

“…Although wool products have moved to a secondary role in economic terms, but as a breeding trait has not lost its significance, because to some extent it has a protective function of the body and characterizes the adaptive ability of the animal [5]. Therefore, when improving the productive qualities of sheep of certain breeds, a comprehensive approach to assessing the constitutional-exterior and productive properties of animals is necessary.…”

The paper deals with the use of admixture crossing in semi-fine-wool sheep breeding in Kyrgyzstan and its results. The purpose of the research was to develop and scientifically substantiate the methods of using the North Caucasian meat and wool breed during admixture crossing for further improvement of the Tian Shan sheep breed. Generally accepted zootechnical methods were used (the classical scheme of introductory crossing), wool qualities were determined on the OFDA device – 2000. The half-blooded (1/2SKTSH) and quarter-blooded (1/4SKTSH) North Caucasian Tian Shan young animals have better wool qualities without reducing the live weight of the crossbreeds. At the same time, the crossbreeds obtained from the back crossing with wool of 58-56 quality in the specific weight of the herd reached 85.5%, and with the most desirable degree of fineness of 56 quality – 63.3%. According to wool density (M+), the proportion of mixed bred young ewes reached 33.3%, which was 25.2% more than that of half-bloods. It was revealed that the inheritance of wool density trait as a result of crossing these breeds had a positive effect on wool productivity. The crossbred wool cut from them had the best marketable appearance. All this makes it possible to switch to the breeding of quarter-blooded North Caucasian Tian Shan animals “in itself” in the future.
