Genetic correlation of average somatic cell score at different stages of lactation with milk yield and composition in Holstein cows
Genetic and non-genetic correlations of the average somatic cell score (SCS) at different stages oflactation (100, 150, 200, 305 and 365 days in milk) with lactation performance were estimated based on thefirst lactation records of Iranian Holstein calving during 2000 to 2009. (Co) variance components wereestimated using derivative-free REML based on multiple traits animal models. The estimated...
متن کاملSingle Nucleotide Polymorphism in the Promoter Region of Bovine Interleukin 8 Gene and its Association with Milk Production Traits and Somatic Cell Score of Holstein Cattle in Iran
Background: Interleukie-8 is a proinflammatory cytokine and a potent chemotactic and activation factor for neutrophils. It has been reported to be expressed in high levels by various cell types after immune stimulation and mediates neutrophil recruitment in host. Objectives: The aim of this study was to analysis of the relationship between single nucleotide polymorphisms (SNPs) at position -18...
متن کاملSingle strand conformation polymorphisms (SSCPs) in the 5'- flanking region of Lactoferrin gene and its association with milk production traits and somatic cell score in Holstein cattle
Lactoferrin (Lf) is a bioactive protein present in all external secretions such as milk that plays important role in the innate host defense. Therefore, the Lf has a major role in bovine mammary gland defense during mastitis. In this study, 5’-flanking region of bovine Lf gene containing three single nucleotide polymorphisms (SNPs) at positions −602 (T/G), −600 (A/G) ...

متن کاملInfluence of the Bovine Acyl-Coa: Diacylglycerol Acyltransferase1 (DGAT1) K232A on Milk Production and Somatic Cell Score Holstein Cows
This experiment was aimed to study the association between the DGAT1 K232A polymorphism and milk production traits and somatic cell score (SCS) in Iranian Holstein dairy cows. The records of 408 animals from five dairy herds were randomly identified and then genomic DNA was extracted from blood using the modified-salting method described by Miller. RFLP-PCR was performed to obtain all the polym...
