Summary The aim of this study was to separate marked additive genetic variability for three quantitative traits in chickens into components associated with classes minor allele frequency ( MAF ), individual chromosomes and marker density using the genomewide complex trait analysis GCTA ) approach. Data were from 1351 measured body weight BW ultrasound breast muscle BM hen house egg production HHP each bird 354 364 SNP genotypes. Estimates variance show that s on commercially available...
Accuracy of genome-wide association studies, and the successful implementation genomic selection depends on level linkage disequilibrium (LD) across genome also persistence LD phase between populations. In present study adjacent SNPs decay was calculated in three Iranian water buffalo Persistence evaluated these populations effective population size (Ne) estimated from corrected r2 information. A set 404 individuals were genotyped with Axiom Buffalo Genotyping 90K Array. Average |D'| SNP...
Abstract Mastitis is known as intramammary inflammation, which has a multifactorial complex phenotype. However, the underlying molecular pathogenesis of mastitis remains poorly understood. In this study, we utilized combination RNA-seq and miRNA-seq techniques, along with computational systems biology approaches, to gain deeper understanding interactome involved in mastitis. We retrieved processed one hundred transcriptomic libraries, consisting 50 matched data, obtained from milk-isolated...
This research seeks to predict in vivo carcass composition of lambs. A total 576 Makoei fat-tailed lambs were used. Lambs 6-7 months fold and weighed about 15.1 - 41.4 kg. Measurements included body weight, upper, middle lower tail-depth width, middle, tail neck circumference, right, left tail-length, length, whither height, abdominal heart girth. Having slaughtered each animal, omental, mesenteric fat separated weighed. Weight fat-tail sum omental contents varied from 50 2290 g 8.1 536 g,...
The aim of this study was to estimate the allele frequencies in polymorphic site exon six POU1F1 gene three Iranian native and Holstein cattle. Genomic DNA extracted from 3 cattle breeds, including 97 Mazandarani, 87 Sarabi, 112 Golpaygani also 110 A 451 bp fragment intron 5 6 were amplified digested with HinfI restriction enzyme. Frequencies 0.37, 0.27, 0.34 0.21 for cattle, respectively. Significant differences genotype found between Mazandarani or No significant Sarabi Transition G...
.Blood samples were collected from a total 816 sheep of both sexes in three Iranian fat-tailed breeds (Sangsari, Makoei, indigenous on firoozkouh mountain) serum, plasma and erythrocyte separated frozen at -20°C. Variation their blood proteins, albumin, haemoglobin transferrin examined to characterize the obtain genetic relationship among them. Only was polymorphic all investigated; while albumin monomorphic for S allele fixed B breeds.
Abstract. Data including 219 105 test day records of 22 569 first parity Holstein cows in 56 herds were analysed for milk yield, fat content and protein content. Legendre polynomials used a random regression model to explain traits curves, additive genetic permanent environmental effects along days (DIM). order 3 describe on the traits. For effects, 6 4 used. Heterogeneity residual variance was considered. Restricted maximum likelihood (REML) methodology estimate required parameters....
