Abstract
In wild animal populations, there is a differentiation between populations due to natural selection. The direction and pressure of natural selection in the wild sheep are different in the various geographic areas. Linkage disequilibrium studies showed that regions of the genome in whole wild sheep are under natural selection and that natural selection can affect immune or reproductive or metabolic traits. The study aimed to identify genomic regions under natural selection in wild sheep. For this purpose, the genetic information of 24 European wild sheep and 24 Sardinian wild sheep was used. The genotypes were determined using Illumina 50 K SNPChip arrays based on Oar_4.0 version of the sheep genome. After quality control steps, finally, 31,560 SNP markers were analyzed. The value of LD was calculated by calculating the r2 statistic between all pairs of locations through PLINK software. To identify signs of selection based on linkage disequilibrium methods, an extended haplotype homozygosity test of XP-EHH crossing population and iHS intrapopulation was used. The results of iHS studies showed that in European and Sardinian wild sheep, the highest iHS coefficient under natural selection was observed on 3 and 2 chromosome numbers, respectively. Also, the results of XP-EHH studies showed that the largest XP-EHH coefficients under natural selection in European wild sheep compared to Sardinian and vice versa in Sardinian wild sheep compared to European wild sheep were observed on 3 and 16 chromosome numbers, respectively. In addition, the results of gene cycle studies showed that COPB1, SEC24D, ZDHHC17, BBS4, RFX3, SLC26A8, CAMK2D, GRIA1, GRM1, GRID2, PPP2R1A, CPEB4, PLEKHA5 and KIF13A, VPS39, VPS53, DTNBP1, DYNC1I1, FAM91A genes are under natural selection in Sardinian and European wild sheeps, respectively. The direction and selection pressure of natural selection in the two breeds of wild sheep is different due to different geographic conditions.

Abstract
We analyzed the effect of a single nucleotide polymorphism, g. C3141T in the 3' UTR of Signal transducer and activator of transcription-1 gene (STAT1) on milk production traits in the Holstein Friesian crossbred cattle of Kerala (n = 144) by association analysis and expression study. The population was genotyped by restriction fragment length polymorphism using Pag1. Association study using the General Linear Model-Analysis of Variance revealed that none of the yield or composition traits analyzed were significantly differed. The expression profile of STAT1 gene in leucocytes of animals bearing homozygous genotypes was compared by quantitative real time PCR using SYBR green chemistry with and relative expression was not found to be significantly differed. The second stage of the study, the STAT1 mRNA spanning 3213 bp was amplified from leucocytes and sequenced (GenBank: MT459802.1). Two novel SNPs were identified; one synonymous mutation in the coding region (g.A1212G) and the other in the 3'UTR (g.T3042C). The novel SNPs might contribute to STAT1 gene regulation mediated by alternate spicing or binding sites for regulatory molecules. The results reiterate the importance of extensive studies of STAT1 gene variants to substantiate the presence of a quantitative trait loci for dairy traits in the vicinity of STAT1 gene.

Abstract
The objectives of the current study were to identify polymorphism in the prolactin receptor (PRLR) gene among three Egyptian goat breeds (Zaraibi, Damascus, and Barki) and to investigate the association between PRLR genotype, parity, season of kidding, and litter size factors with milk yield and reproductive traits of Zaraibi goats. One hundred and ninety blood samples were collected for DNA extraction, with 110 from Zaraibi, 40 from Barki, and 40 from Damascus breeds. Three genotypes, CC, CT and TT, for the prolactin receptor gene were identified in the 190 DNA samples using restriction fragment length polymorphism and were confirmed by direct sequencing technique. Milk yield during suckling and lactation periods in addition to age at first conception, gestation length, and litter size were determined in 110 Zaraibi goats. The Zaraibi goats recorded the highest heterozygosity (0.495) and the effective number of alleles (1.972). The g.62130C > T SNP showed a significant association (p < 0.01) with suckling, lactation, and total milk yield of Zaraibi goats with the highest values recorded at the third parity. Age at the first conception and gestation length traits were significantly influenced by the kidding season (p < 0.05) with younger age in autumn and shorter length in spring seasons. Milk yield during the suckling period was significantly (p < 0.01) higher in the case of triplets' litter size. The current study showed that litter size and parity played an important role in the amount of Zaraibi goats' milk yield. The g.62130C > T SNP of the PRLR gene may be a useful marker for assisted selection programs to improve goat milk yield during suckling and lactation periods with the heterozygous genotype CT recording the highest values.

Abstract
This study was to investigate the correlations of myogenic differentiation 1 (MYOD1) gene polymorphisms with carcass traits and its expression with breast muscle development in pigeons. Four SNPs were found in the pigeon MYOD1 gene. Correlation analysis showed that individuals with AA genotype at both SNPs g.2967A > G (p < .01) and g.3044G > A (p < .05) have significantly higher live weight (LW), carcass weight (CW), semi-eviscerated weight (SEW), eviscerated weight (EW) and breast muscle weight (BMW). Moreover, the two SNPs also had the same significant effects on MYOD1 mRNA expression levels in breast muscle of pigeons, ie, the AA genotype showed higher MYOD1 mRNA expression levels. The diameter and cross-section area of muscle fibers continuously increased from 0w to 4w (p < .05), accompanied with the increasing expression of MYOD1 gene, while the density decreased (p < .05) dramatically from 0w to 1w and continuously fell over in the next few weeks (p > .05). What's more, the expression level of MYOD1 gene was positively correlated with a diameter (r = 0.937, p < .05) and cross-sectional area (r = 0.956, p < .01) of myofiber, and negatively correlated with density (r = -0.769, p < .01). The results showed that individuals with AA genotype at both SNPs g.2967A > G and g.3044G > A have showed higher carcass traits (LW, CW, SEW, EW, and BMW) and higher MYOD1 mRNA expression level in breast muscle than AB and BB genotypes. Moreover, the expression level of MYOD1 gene was closely correlated with muscle characteristic traits, indicating variants of MYOD1 gene was closely related to muscle development and could be a potential candidate gene in marker-assisted selection of pigeons.

Abstract
Equines' ability in racing and riding as well as gaitedness have influenced the human civilization. Aim of this study was to identify and characterize the novel polymorphisms or SNPs in DMRT3 gene in Indian horse and donkey breeds. In this study, the DMRT3 gene was sequenced and characterized in 72 Indian horses' and 33 Indian donkeys' samples. One SNP (A > C) at 878 was found in studied horses while identical SNPs (A > C) at two different nucleotide positions i.e., 878 and 942 in DMRT3 gene (chromosome 23) were observed in studied Indian donkey breeds. Horses and donkeys both have a non-synonymous mutation (A > C) at nucleotide 878 (codon 61) that converts a Stop codon (TAG > TCG) to coding codon Serine, whereas donkeys have a synonymous mutation at nucleotide 942 (codon 82) that converts Serine (TCA > TCC) into Serine. A phylogenetic tree indicated that the DMRT3 gene was equally distributed among the equine breeds. Most of the donkey breeds have been shown high levels of genetic diversity while horse breeds and Halari donkey showed the least genetic diversity. Mutation in DMRT3 has a major impact on gaitedness in horses and is presented at a high frequency in gaited breeds and in horses breed for harness racing.

Abstract
This study investigated the associations between the c.189G > T polymorphism of the insulin receptor substrate-1 (IRS-1) gene and the growth and litter size-related traits in the Native rabbit in Middle Egypt (NMER). One hundred sixty-two NMER rabbits were genotyped by RFLP-PCR using Sau3AI restriction enzyme and the associations of the reported genotypes with body weights at 5th, 6th, 8th, 10th, and 12th week old, body gain, and daily gain plus, the litter size-related traits were determined. Additionally, the genotypic and allelic frequencies, the effective (Ne) and observed (NA) numbers of alleles, observed (Ho) and expected (He) heterozygosity, Hardy-Weinberg equilibrium (HWE), and the decrease in heterozygosity because of inbreeding (FIS) were calculated. Three genotypes; GG, GT, and TT with 0.65, 0.33, and 0.02 frequencies, respectively which fit HWE were reported. These genotypes displayed a marked low FIS value. Significant associations of the genotypes with the body weights, and gains, except at the 5th week old determined with superiority of the GT genotype compared with the other genotypes. All reported litter size-related traits significantly varied among different genotypes. In summary, the c.189G > T SNP of the IRS-1 gene is an effective genetic marker to improve growth performance and litter size traits of the NMER rabbits.

Abstract
To contribute to the knowledge of maternal genetic diversity in domestic donkeys, this study investigated the mitochondrial DNA variations and analyzed the genetic structure in Indian donkeys based on 31 mitogenome sequences representing four breeds/populations (Agra, Halari, Kachchhi and Spiti). A total of 27 haplotypes with a haplotype diversity value of 0.989 were evident in the donkey genetic resources of India. The genetic differentiation between the investigated populations was evaluated using population pairwise FST values, which showed maximum differentiation between Kachchhi and Halari donkeys. The Neighbor-Joining (NJ) tree based on the whole mitogenome sequence and the Median-Joining (MJ) network for partial D-loop fragment showed clear demarcation of Indian donkeys into Nubian and Somali clades, substantiating African maternal origin of Indian domestic donkeys. The topology of the MJ network excluded the Asian wild asses as the possible progenitors of Indian donkeys. Halari and Agra donkeys showed conformity exclusively to the Nubian lineage of the African wild asses. However, representation of both the Nubian and Somali lineages was observed in Kachchhi and Spiti donkeys. Comprehensive analysis carried out by retrieving D-loop sequences from different countries representing Asia, Africa, Europe and South America revealed existence of shared haplotypes across geographically isolated regions of the globe. This observation is indicative of utility of donkeys as pack animals across inter-continental trading routes during development of human civilizations. Our results represent a valuable contribution to maternal genetic diversity of Indian donkeys and provide insights into the worldwide spread of the species following initial domestication in Africa.

BIOMED RESEARCH INTERNATIONAL 2023; 2023:8823863.

Abstract
The 32 bp deletion in the chemokine receptor (C-C motif) 5 gene (CCR5Δ32) is a natural loss of function polymorphism that prevents the protein from locating on the cell surface. This genetic variation acts as a double-edge sword in the pathogenesis/defense mechanism of different health conditions, such as viral infections, autoimmune diseases, and cancers. Here, we evaluated the prevalence of the CCR5Δ32 polymorphism in the Turkmen population of Golestan province, northeast of Iran. Blood samples were collected from 400 randomly selected Turkmen populations (199 women and 201 men), and genomic DNA was extracted. Characterization of CCR5Δ32 genotypes was performed by PCR using primers flanking the 32-nucleotide deletion in the CCR5 gene. The amplified DNA fragments were visualized on 2% agarose gel electrophoresis with cybergreen staining under UV light. All individuals were of Turkmen ethnicity and lived in the Golestan province, northeast of Iran. The mean age of all participants was 35.46 years, with a 20-45 year range. All the studied subjects were healthy without any severe conditions such as autoimmune disease and viral infections. All individuals had no history of HIV infection. The PCR product visualization showed that all the samples are at the 330 bp size, which means the CCR5Δ32 allele was utterly absent from the study population. The presence of the CCR5Δ32 allele among Turkmens may be attributed to the admixture with European descent people. We conclude that the CCR5Δ32 polymorphism may be absent in the Iranian Turkmen population, and further studies with a large population are needed.

Abstract
During the last decade, research into genetic markers in the casein gene cluster has been actively introduced in cattle breeding programs. A special interest has been paid to the polymorphism of the CSN3 gene, responsible for the expression of the k-casein, playing a key role in protein coagulation, interaction with whey proteins, stabilization, and aggregation of casein micelles. This paper aimed to determine the effect of CSN3 genetic polymorphism on acid; rennet; acid-rennet; heat- and acid-induced as well as heat- and calcium-induced coagulation in skimmed milk; and protein-standardized milk systems (UF, NF, RO, VE). The influence of polymorphic variants of the CSN3 gene on the coagulation ability of milk proteins was assessed by the particle size of casein micelles, protein retention factor in the clot, and coagulation ability (duration of induction period, mass coagulation period, dynamic viscosity in gel point). The correlation between CSN3 gene polymorphism and protein coagulation was revealed. Milk systems obtained from CSN3 BB milk were found to have the shortest duration of coagulation, formation of better gel strength values, and increased yield compared to CSN3 AA. This study will improve the efficiency of milk processing and optimize the technology of dairy product production.

Abstract
Milk proteins determine important milk technological characteristics. Among caseins, Ƙ-casein has been correlated with fat and protein content and cheese yield. Fourteen Ƙ-caseins variants have been described but the alleles A, B and E are the most important ones due to their frequency and/or influence on the technological aptitudes of milk. Therefore, in the present study two different duplex qPCR assays with locked nucleic acid probes (for positions 13104 and 13124 of the Ƙ-casein gene) were developed for the detection of A, B and E variants. Firstly, DNA isolation method from milk somatic cells and hair was optimised. The developed 13124-qPCR assay showed an increased sensitivity reaching up to 6.7 copies DNA copies/reaction at a 95% confidence level with A, B and E alleles reference samples. The 13104-qPCR assay reached up to 6.7 DNA copies/reaction for A allele reference sample and 67 DNA copies/reaction for B and E samples. Intra-assay variation results were below 6%. Applicability was determined using DNA samples from animals with known genotype for Ƙ-casein (AA, AB, BB, BE, AE, EE) and both assays were able to discriminate among the six genotypes with 100% accuracy. Thus, this qPCR method represents a sensitive and rapid option for the detection of Ƙ-casein alleles in both hair and milk samples.

Abstract
ABSTRACT κ-Cn and β-lactoglobulin are important candidate genes associated with milk yield and milk protein content. The present investigation is carried out to determine the polymorphisms status of κ-Cn and β-lactoglobulin genes in Anatolian Black cattle and Holstein breeds. PCR-RFLP technique was used to determine Kappa-Casein and β-lactoglobulin polymorphisms in both cattle breeds. The allele frequency of Anatolian Black cattle in terms of κ-Cn and β-lactoglobulin genes were 0.50 (A) 0.50 (B) and 0.20 (A) 0.80 (B) respectively, whereas in Holstein were 0.29 (A) 0.71 (B) and 0.44 (A) 0.56 (B) respectively. The chi-square test showed that each cattle breed was in Hardy-Weinberg equilibrium (P>0.05).

Abstract
Buffalo is a luxurious genetic resource with multiple utilities (as a dairy, draft, and meat animal) and economic significance in the tropical and subtropical regions of the globe. The excellent potential to survive and perform on marginal resources makes buffalo an important source for nutritious products, particularly milk and meat. This study was aimed to investigate the evolutionary relationship, physiochemical properties, and comparative genomic analysis of the casein gene family (CSN1S1, CSN2, CSN1S2, and CSN3) in river and swamp buffalo. Phylogenetic, gene structure, motif, and conserved domain analysis revealed the evolutionarily conserved nature of the casein genes in buffalo and other closely related species. Results indicated that casein proteins were unstable, hydrophilic, and thermostable, although αs1-CN, β-CN, and κ-CN exhibited acidic properties except for αs2-CN, which behaved slightly basic. Comparative analysis of amino acid sequences revealed greater variation in the river buffalo breeds than the swamp buffalo indicating the possible role of these variations in the regulation of milk traits in buffalo. Furthermore, we identified lower transcription activators STATs and higher repressor site YY1 distribution in swamp buffalo, revealing its association with lower expression of casein genes that might subsequently affect milk production. The role of the main motifs in controlling the expression of casein genes necessitates the need for functional studies to evaluate the effect of these elements on the regulation of casein gene function in buffalo.

Abstract
<p>Objetivou-se caracterizar o genótipo da kappa-caseína em 144 vacas Girolando, do Estado de Pernambuco, utilizando a técnica de PCR-RFLP. Foram coletadas amostras de sangue total desses animais dos seguintes grupos genéticos: 30 ½ holando-gir, 38 ¾ holando-gir e 76 ⅝ holando-gir. Desse material foi extraído o DNA. Através do DNA foi determinada uma região que foi amplificada e seu produto sofreu ação da enzima de restrição HindIII para observar os possíveis polimorfismos. Foram encontrados os seguintes genótipos com respectivas frequências: AA (0,59); AB (0,25) BB (0,06); AC (0,05); BC (0,02) e CC (0,02). As frequências alélicas observadas para os genes A, B e C foram 0,74; 0,20 e 0,06, respectivamente. Há de se registrar a detecção do gene C na população, raramente descrito em outros trabalhos. A presença do genótipo BB na população de vacas holando-gir aponta para implantação de programas de seleção genética visando aumento na frequência do genótipo em questão, o que possibilitará ganhos significativos na cadeia do leite, particularmente, para produtores e indústrias de processamento.</p>

Abstract
In cattle, caseins are subdivided into four main groups: alphaS1-, alphaaS2-, beta- and kappa-caseins. kappa-caseins (CSN2) considerably differ from other caseins in structure and other properties. Testing the A and B alleles is of practical importance, because the milk of cows that carry the B allele of CSN3 has a better thermal resistance and shorter coagulation time, better curdles and contains micelles of different sizes. Iranian Sistani cattle (Bos indicus) are a heavy built breed and used as dual-purpose cattle breed in Eastern Iran. This breed is a genetic resource that shows special features of adaptation to rustic environments. One of the most distinctive features of Sistani cattle is its great capability to resist diseases which makes it a potential reservoir of germplasm useful for future crosses. Our main goal was to study DNA-polymorphism of the CSN3 gene in the Iranian Sistani native cattle (Bos indicus) and analyze the information value of CSN3 gene polymorphism as a genetic marker. We genotyped and analyzed 65 animals of this breed using PCR-RFLP. The frequencies of A and B alleles were 0.6385 and 0.3615 and those of AA, AB and BB genotypes were 0.4000, 0.4769 and 0.1231, respectively. In the Sistani Zebu breed, frequency of B allele is higher than other Zebu breeds, indicating that intensive selection for dairy production have been done and indirectly influenced CSN3 allele frequencies.
