Context Greater production of oocytes and embryos from Gir donors contributes to greater fertility genetic progress. Aims This study aimed obtain parameters for oocyte embryo in the breed. Methods Repeatability random regression models were applied data consisting 17 526 Ovum Pick Up observations 1641 five different herds. Single multi-trait analyses carried out with application both traits: number viable oocytes, total embryos, using BLUPF90 family programs. Legendre polynomials second...
Abstract Runs of homozygosity (ROH) and signatures selection are results processes in livestock species that has been shown to affect several traits cattle. The aim the current work was verify profile ROH inbreeding depression number total (TO) viable oocytes (VO), embryos (EMBR) Gir Indicine In addition, we aimed identify selection, genes enriched regions between subpopulations sorted by breeding value for these traits. genotype file contained 2,093 animals 420,718 SNP markers. Breeding...
Imprinting is a phenomenon that alters the expression of genes according to parental origin their alleles. A quantitative form evaluate imprinting effect known as parent-of-origin effect. Our aim with this work identify effects influence number oocytes and embryos in Gir dairy cattle. dataset 17,526 Ovum Pick Up observations from 1,641 donors was used estimate for traits total (TO), viable (VO) (EM). To effects, dam sire gametic were included, individually or together, an animal model TO, VO...
In vitro embryo production is one of the main reproductive techniques used in dairy Gyr cattle. addition, linear type measures are well characterized and have been breed selection for last 4 decades. The estimation genetic parameters number aspirated oocytes vitro-produced embryos associated with would support progress animal breeding programs toward production. This study aimed to estimate oocytes, production, traits, exploring association between them. repeatability model was applied...
Abstract Genome-Wide Association Studies (GWAS) are used for identification of quantitate trait loci (QTL) and genes associated with several traits. We aimed to identify QTLs, genes, biological processes number total viable oocytes, embryos in Gir dairy cattle. A dataset 17,526 follicular aspirations, including the following traits: oocytes (VO), (TO) (EMBR) from 1,641 donors was provided by five different stock farms. genotype file 2,093 animals 395,524 SNP markers perform a single-step...
Imprinting is the best example of parent-of-origin effects influencing phenotypic variance. Our aim with this work to identify parental origin imprinting that influence number oocytes and embryos in Gir dairy cattle. A dataset 17,526 Ovum Pick Up (OPU) observations from 1,641 donors was used prospect for traits total (TO), viable (VO) (EMBR). To effects, dam sire gametic were included, individually or together, an animal model TO, VO EMBR traits. Single trait models applied each both...
Abstract Our objective was to establish a SNPs panel for pedigree reconstruction using chips of different densities and evaluate the genomic relationship coefficient inferred pedigree, in addition analyzing population structure based on analyses Gir cattle. For parentage analysis relationship, 16,205 genotyped animals were used being 14,458 females 1,747 males, 1,810 common markers four SNP chips. analyses, which include linkage disequilibrium, effective size, runs homozygosity (ROH),...
