The aim of this study was to characterize the lactational performance of Mongolian native mares grazing on natural pastureland by revealing the seasonal effects on metabolic parameters. In this study, 8 multiparous mares were used. Milk yield and composition and serum metabolic parameters, such as alanine aminotransferase, aspartate aminotransferase (AST), glucose (GLU), triacylglycerol, total cholesterol (TCH), non-esterified fatty acid (NEFA), albumin, urea, total protein, cortisol (Cort), and insulin, were determined at 30, 60, 90, 120, 150, 180, 210, 240, and 270 days of lactation. During the lactation period, milk yield peaked at around the 90th day and declined sharply in the following period. While the milk fat and protein contents decreased gradually from the early stages of lactation to the late stages, the lactose content was highest at mid-lactation and stayed constant until the end of the lactation period. Meanwhile, changes were observed between the stages of lactation, and the differences in metabolic parameters were significant (P<0.05), except for AST and GLU. The strongest correlation was found with NEFA (P<0.01), followed by the Cort (P<0.05) concentration, with both parameters showing negative correlation, and strong positive correlation was detected between the milk yield and TCH (P<0.05) concentration.","PeriodicalId":35701,"journal":{"name":"Journal of Equine Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/e6/42/jes-32-091.PMC8437754.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39429116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To reveal the genetic characteristics of this breed, we investigated haplotypes of mitochondrial DNA (mtDNA) and single-nucleotide polymorphisms of the Y chromosome, as well as genotypes of five functional genes associated with coat color, body composition, and locomotion traits. We detected 10 mtDNA haplotypes that fell into 8 of the 17 major haplogroups of horse mtDNA, indicating a unique haplotype composition with high genetic diversity. We also found two Y-chromosomal haplotypes in Kushum horses, which likely originated from Trotter and/or Don breeds. The findings regarding the mtDNA and Y-chromosomal haplotypes are concordant with the documented maternal and paternal origins of the Kushum horses. The allele frequencies of ASIP, MC1R, and MATP associated with coat color were consistent with the coat color variations of Kushum horses. The allele frequencies of MSTN associated with endurance performance and those of DMRT3 associated with gait suggested that the observed allele frequencies of these genes were the result of selective breeding for these traits. As a result of this study, we were able to obtain useful information for a better understanding of the origin and breeding history of the Kushum horse breed using molecular markers.","PeriodicalId":35701,"journal":{"name":"Journal of Equine Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/6e/96/jes-31-035.PMC7538259.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38494261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
