Abstract
This study is first to perform a genome-wide association study (GWAS) to investigate the milk quality traits in Karachai goats. The objective of the study was to identify candidate genes associated with milk composition traits based on the identification and subsequent analysis of all possible SNPs, both genome-wide (high-confidence) and suggestive (subthreshold significance). To estimate the milk components, 22 traits were determined, including several types of fatty acids. DNA was extracted from ear tissue or blood samples. A total of 167 Karachai goats were genotyped using an Illumina GoatSNP53K BeadChip panel (Illumina Inc., San Diego, CA, USA). Overall, we identified 167 highly significant and subthreshold SNPs associated with the milk components of Karachai goats. A total of 10 SNPs were located within protein-coding genes and 33 SNPs in close proximity to them (±0.2 Mb). The largest number of genome-wide significant SNPs was found on chromosomes 2 and 8 and some of them were associated with several traits. The greatest number of genome-wide significant SNPs was identified for crude protein and lactose (6), and the smallest number-only 1 SNP-for freezing point depression. No SNPs were identified for monounsaturated and polyunsaturated fatty acids. Functional annotation of all 43 SNPs allowed us to identify 66 significant candidate genes on chromosomes 1, 2, 3, 4, 5, 8, 10, 13, 16, 18, 21, 23, 25, 26, and 27. We considered these genes potential DNA markers of the fatty acid composition of Karachai goat milk. Also, we found 12 genes that had a polygenic effect: most of them were simultaneously associated with the dry matter content and fatty acids (METTL, SLC1A 8, PHACTR1, FMO2, ECI1, PGP, ABCA3, AMDHD2). Our results suggest that the genes identified in our study affecting the milk components in Karachai goats differed from those identified in other breeds of dairy goats.

Abstract
The objective of this study was to investigate the response of Charolais and Ile-de-France meat sheep breeds to stimulate superovulation with various follicle-stimulating hormone (FSH) preparations. A total of 14 adult ewes of meat sheep breeds were used in our study as donors, including Charolais breed (n = 8) and Ile-de-France breed (n = 6). Donors ewes were randomly divided into two groups in equal numbers (first group, n = 7; second group, n = 7), every group included Charolais breed (n = 4) and Ile-de-France breed (n = 3). Ewes in the first group were treated with Folltropin-V (total dose of 200 mg per ewe, seven injections), and ewes in the second group were treated with FSH-P (total of 280 IU per ewe, six injections). Thirty-seven ewes of Edilbay breed used as recipients were divided into two groups (first group, n = 20; second group, n = 17). Our results showed that the number of corpora lutea in donor groups treated with Folltropin-V was significantly higher than in donor groups treated with FSH-P (p < .01). A greater number of embryos recovery and embryos suitable for transplantation were found in the first group compared with the second group of donors. After 30 days from transplantation, transabdominal ultrasonography showed that the presence of pregnancy in recipients groups was found in 16 recipient ewes (43.2%), in the first group of recipients were registered nine pregnant ewes of 20 recipient ewes (45.0%), and in the second group of recipients were registered seven pregnant ewes of 17 recipient ewes (41.2%). In conclusion, using Folltropin-V in Charolais and Ile-de-France meat sheep breeds is a more effective scheme for stimulating superovulation than using FSH-P.

Abstract
In a vegetation experiment with soybean plants of the Svapa and Mageva varieties and in a field experiment with bean plants of the Geliada and Shokoladnitsa varieties, we studied the effect of pre-sowing treatment of the seeds of these plants with Rizotorfin and Epin-extra on the nitrogenase activity of the nodules of these plants and their ultrastructure. Analysis of the ultrastructure of the nodule tissue of beans and soybeans was carried out in the flowering phase. It was found that the highest indices of the mass and number of nodules and the activity of nitrogenase in them were found in bean plants of the Heliada cultivar when the seeds were treated with Epin-extra against the background of inoculation with Rizotorfin, where the largest area of symbiosomes, volutin and their number was noted in the nodules. Beans of the Shokoladnitsa variety showed the protective effect of Rizotorfin. In the nodules of soybean plants of the Svapa variety, the seeds of which were treated with Epin-extra against the background of inoculation with Rizotorfin, the presence of a large number of symbiosomes, bacteroids, volutin inclusions with a larger area and a minimum number of inclusions of poly-β-hydroxybutyric acid (PHB) was noted, and the highest indicators of symbiotic activity. Soybean plants of the Mageva variety showed the protective effect of Rizotorfin. The efficiency of the symbiotic system was determined by the number and weight of nodules and the activity of the nitrogenase enzyme.

Abstract
The aim of the present study was to evaluate seasonal changes in testes size, serum testosterone (T) levels and sperm production characteristics of 24 adult (2-3 years old) rams of meat breeds: Charollais (n = 6), Ile de France (n = 6), Dorset (Polled) (n = 5) and Dorper (Dorper, n = 7). Semen was collected with artificial vagina using a female in spontaneous oestrus (September-November, breeding season, BS) or a female with induced oestrus (March-July, non-breeding season, NBS). A total of 672 ejaculates were examined. Jugular vein blood was collected to determine testosterone levels during BS and NBS, and serum was extracted. Results of the present study indicate that there was no significant change in parameters such as body weight (kg) and testes length, both right and left, during BS and NBS, irrespective of the breed. The remaining metrics of testes differ in varying degrees between breeds of rams (with the exception of the Dorper breed) between BS and NBS. No significant variation in these parameters was found in Dorper rams. For all breeds, season had a statistically significant effect on important parameters such as total sperm count and progressive sperm motility after thawing. There was also significant seasonal variation in ejaculate volume across the three breeds, excluding il-de-France rams. The most constant was the sperm concentration, which was unchanged in BS and NBS in the three breeds, excluding Dorset rams, which showed a slightly significant decrease in this indicator in the non-breeding season. The serum content of the major male hormone testosterone (T) in rams of all breeds showed significant changes between BS and NBS, decreasing by a highly significant amount in the non-breeding season.

Abstract
The introduction of modern technological advances and principles of dairy herd management, which were developed in the member countries of the International Committee for Animal Registration (ICAR), contributed to the increase in milk productivity of pedigree cattle at the national level. The harmonization of national regulatory documents with the methodological principles developed in ICAR is a promising area. The study of new methodological approaches to the assessment of milk productivity shows that one of the differences in the assessment of daily milk yield, milk fat and protein yield is the different frequency of performing the corresponding work on the control milking of cows, the formation of a daily milk sample and the necessary mathematical calculations. In the in article various approaches to assessing the daily yield of the main dairy components during 2- and 3-fold milking of cows of a herd of pedigree black-and-white cattle are considered and coefficients are proposed for recalculating the daily content of fat and protein in milk. At the same time, the presented research results, in general, coincide with the main trends in the dynamics of milk fat and protein indicators shown in the ICAR recommendations.

Abstract
The article presents the findings on the dynamics of the live weight of calves of various breeds in similar climatic conditions in arid regions of the Stavropol Krai of Russia and the steppe zone of Ukraine. It has been established that the live weight of calves of the Hereford, Kazakh white-headed and Kalmyk breeds when raised according to the traditional technology of beef cattle breeding when calves are sucked under cows up to 6-7 months of age, is in relationship with the milk qualities of mothers. At the same time, the live weight of the gray Ukrainian calves was interrelated regarding the live weight at birth and the feeding technology. A positive relationship was shown in the live weight of calves at birth and during their implementation at 15 and 18 months of age. Most effectively animals used pasture fodder in spring and summer. In an arid climate, it is more appropriate to breed specialized cattle belonging to the Hereford breed and then sell them for breeding in other farms in the region.

Abstract
An understanding of what effects particular genes can have on body parameters in productive animals is particularly significant for the process of marker-assisted selection. The gene of transcriptional factor CCAAT/enhancer-binding protein delta (CEBPD gene) is involved in the process of growth in animals and is known to be a promising candidate for use as a genomic marker. The structure of the CEBPD gene locus was determined using NimbleGen sequencing technology (Roche, USA). The effect of polymorphisms, which were identified using the aforementioned technology, was investigated in 30 rams of the Manych Merino sheep breed. Twenty-two single nucleotide polymorphisms (SNP) were detected in the CEBPD gene locus. Significantly, two SNPs, namely, g.315T>G and g.327C>T, have been identified for the first time. It was demonstrated that the complex of linked SNPs, consisting of g.301A>T, g.426T>C, and g.1226T>C, had a negligible effect on body parameters in Manych Merino sheep. Animals with the heterozygous type of SNP g.1142C>T exhibited changes solely in the chest and croup width. The newly discovered SNP g.327C>T was proven to have a negative effect on live weight and body size (p < 0.05) in Manych Merino sheep. Sheep with the heterozygous type of g.562G>A and g.3112C>G SNP complex showed an increase in live weight and dimensions (p < 0.05) compared with those of wild homozygous type. Consequently, SNPs g.327C>T, g.562G>A, and g.3112C>G in the CEBPD gene locus can be successfully used as markers in sheep breeding. Future research will evaluate the influence of the aforementioned SNPs on slaughter indicators for sheep meat production.
