Abstract
  Introduction: Bovine Leukemia Virus (BLV) infection is more common in dairy cattle herds. The main cause of leukosis is the disease that leads to the creation of cancerous lymphocytes in different organisms of the body and affects different species, including cattle. This disease reduces milk production ...  Read More

Volume 22, Issue 4 , December 2020, , Pages 515-527

https://doi.org/10.22059/jap.2020.307226.623552

Abstract
  In order to evaluate the effect of genotype by environment interaction on production traits of Holstein cattle of Iran, first lactation test day records of 344170, 135000 and 156840 of milk, fat and protein yield on 34417, 13500 and 15684 cows and SNP markers of 1935 genotyped bulls were used. The ...  Read More

Volume 20, Issue 4 , February 2019, , Pages 499-511

https://doi.org/10.22059/jap.2018.261461.623301

Abstract
  The objective of the present study was the genetic evaluation of retained placenta (RP), metritis (MET), number of inseminations to conception (INS), and days open (DO) in Holstein cows using standard (SMMs) and recursive (RMMs) mixed models. Data on 50230 first-lactation Holstein dairy cattle, collected ...  Read More

Volume 20, Issue 1 , May 2018, , Pages 29-41

https://doi.org/10.22059/jap.2018.236405.623221

Abstract
  This study was conducted to estimate the linkage disequilibrium (LD) and determine haplotype blocks structure in 93 Sarabi cow using SNP-chip 40k of Illumina company. After genotyping and quality control, 27386 SNP markers on autosomal chromosomes remained for analyzing. The LD was measured by r2 and ...  Read More

Volume 15, Issue 1 , July 2014, , Pages 65-77

https://doi.org/10.22059/jap.2013.36604

Abstract
  The objective of this study was to compare six statistical methods for prediction of genomic breedingvalues for traits with different genetic architecture in term of gene effects distributions and number ofQuantitative Traits Loci (QTLs). A genome consisted of 500 bi-allelic single nucleotide polymorphism(SNP) ...  Read More
