Association between DGAT1 Genotype and Breeding Value of Milk Production Traits in Iranian Holstein Bulls
The aim of this study was to test the genotypes effect of DGAT1 gene on breeding value in Iranian Holstein milk production traits. For this purpose, 103 semen samples of registered bulls were collected and then genotyped for partial region of DGAT1 gene. The studied traits were milk yield (MY), fat yield (FY), protein yield (PY), fat percentage (FP) and protein percentage (PP). First lactation ...

متن کاملThe Association of Bovine Osteopontin (OPN) Gene with Milk Production Traits in Iranian Holstein Bulls
Background: The Osteopontin (OPN) is a highly phosphorylated glycoprotein in numbers of bovine tissues and milk. OPN has been reported to be associated with milk production in cattle. Objective: The genotype and allelic frequencies for OPN and its association with milk production will be evaluated in Iranian Holstein Bulls. Materials and Methods: Bulls DNA (100) was isolated. Oligo was used f...

متن کاملPrediction of breeding values for the milk production trait in Iranian Holstein cows applying artificial neural networks
The artificial neural networks, the learning algorithms and mathematical models mimicking the information processing ability of human brain can be used non-linear and complex data. The aim of this study was to predict the breeding values for milk production trait in Iranian Holstein cows applying artificial neural networks. Data on 35167 Iranian Holstein cows recorded between 1998 to 2009 were ...
