[ 1 ] - The Effect of Dams of Sire Path Management on Genetic and Economic Parameters in a Simulated Genomic Selection Program
A deterministic model based on the gene flow method, considering the features of Iranian Holstein cattle population, was implemented in this study to evaluate the effect of altering the number of age-classes in the dams of future sire (DS) path and the number of dams required for breeding a young bull (YB), to be evaluated as future sire, on genetic gain and resultant economic efficiency of a g...
[ 2 ] - Estimation of Genetic Trends for Test-Day Milk Yield by the Logarithmic Form of Wood Function Using a Random Regression Model
Estimation of genetic trends is necessary to monitor and evaluate selection programs. The objective of this study was to estimate the genetic trends for milk yield in Iranian Holsteins cows using random regression test day model. Data set was consisted of 743205 test-day records from 1991 to 2008, which were collected by the Animal Breeding Centre of Iran. Breeding, environmental and phenotypic...
[ 3 ] - Genetic Polymorphism Detection of the Exon 1 Region of Acetyl-CoA Carboxylase Alpha Gene in Iranian Mahabadi Goat Breed
Acetyl-coenzyme A carboxylase α (ACC-alpha) is considered as the key regulatory enzyme in fatty acid biosynthesis. ACC-alpha gene is located on Caprine chromosome 11 and is polymorphic in many goat breeds. In the current study, we aimed to find possible single nucleotide polymorphisms (SNPs) in the exon 1 region of the ACC-alpha gene in Iranian Mahabadi goat breed. Genomic DNA was extracted fro...
