Article Synopsis
- This study examined the genetic diversity and selection signatures in four indigenous Iranian horse breeds: Caspian, Turkmen, Kurdish, and Persian Arabian, using genomewide genotyping data from 169 horses.
- The research identified distinct phylogeographic clades based on the horses' geographic origins and revealed a range of significant single nucleotide polymorphisms (SNPs) associated with traits like height and adaptability.
- Findings highlighted specific candidate genes, such as HMGA2 and LLPH, linked to height variation, and suggested new candidate genes for selection, offering insights for genetic conservation and breeding strategies.
Background: Development of exogenous enzymes is one of the most important discoveries in animal nutrition. The supplementation of exogenous enzymes in broiler diets allows for supplying nutrient deficiencies and to decrease endogenous losses.
Objectives: The effects of phytase (Hostazym and Phyzyme) and xylanase (Ronozyme) enzymes were investigated on growth performance and Mucin2 gene expression in broilers.
Background: Kurdish horse is one of the most valuable horse genetic resources in the Middle East.
Objectives: To assess the genetic diversity of Kurdish horses, Mitochondrial DNA D-loop hyper-variable region1 (HVR1) was sequenced in 29 non-related Kurdish horses which were sampled from diverse geographic regions of Iran.
Methods: Total DNA was extracted from the collected blood samples by modified salting out method.
The genetic diversity and genomic regions being under putative natural selection in Kurdish horse population were studied. The samples from 72 horses were genotyped by using GGP Equine 70K SNP arrays. The Ne Slope (NeS) analyses revealed that a sharp decline in Ne has probably occurred around four generations ago, and high frequency of ROH with 2-4 Mbp in length suggested that the inbreeding has probably occurred around 20 generations ago.

The aim of this study was to evaluate genetic characterization of the Caspian horse population using microsatellite markers. This study determined the efficiency of microsatellite markers for conservation plans and breeding strategies in Caspian horse population. For this purpose, 120 Caspian horse samples including 95 adults and 25 foals were genotyped by using seventeen microsatellite markers recommended by ISAG.
