Genetic Analysis of Milk Yield in Iranian Holstein Cattle by the Test Day Model
Using monthly test day records the genetic parameters of Iranian Holstein cattle in first lactation were studied. Data of 277400 test-day milk records from 65320 cows and 2210 sires were analyzed by an animal random regression model using restricted maximum likelihood methodology. The model included herd-test-date, interaction between year-season of calving, days in milk (linear and quadratic) ...
متن کاملGenetic Association Analysis of Paratuberculosis Forms in Holstein-Friesian Cattle
A genetic susceptibility to Mycobacterium avium subsp. paratuberculosis (MAP) infections in ruminants has been longtime suspected to exist. Recently, natural infections in cattle have been reclassified into latent and patent forms based on histopathological findings and their associations with immunological and microbiological variables. This study aims to explore whether these newly defined ph...
متن کاملGenetic Evaluation of Calving Ease for Walloon Holstein Dairy Cattle
Calving complications have an incidence on the economic profitability of dairy herds. In the Walloon Region of Belgium, calving ease data recording is being done on voluntary basis since 2000. This allows now the implementation of a genetic evaluation of Holstein dairy cattle addressing the need of dairy breeders to select bulls in order to reduce frequency of calving problems. Calving ease sco...
متن کاملPCR-SSCP Analysis of Genetic Variation in DNMT Gene Family in Holstein Cattle
Members the DNA Methyltransferases (DNMT) gene family have been shown to play fundamental roles in regulating embryonic growth and development from embryonic fertilization to postnatal life; through regulating the establishment and/or maintenance of specific epigenetic marks. The present study was conducted to identify potential reported mutations within the exon 33 of DNMT-1, intron 4 of DNMT-...
متن کاملGenetic Polymorphisms of Cytochrome P450 2D14 (CYP2D14) Gene in Japanese Black Cattle and Holstein-Friesian Cattle
Two types of cytochrome P450 2D14 (CYP2D14) gene deletions (GD1 and GD2) in Japanese Black cattle has been reported by us. In this study, we determined the frequency of cytochrome P450 2D14 (CYP2D14) genetic polymorphisms in 48 Japanese Black (JB) and 48 Holstein-Friesian (HF) cattle using polymerase chain reaction (PCR)-direct sequencing. Two types of CYP2D14 gene deletion variants, GD1 and GD...
