genomic selection (gs) is a tool for prediction of breeding values for quantitative traits. for a successful application of gs, accuracy of predicted genomic breeding value (gebv) is a key issue to consider. here we investigated the accuracy of gebv in 345 genotyped iranian holstein cattle. the study was performed on milk, fat, protein yield and somatic cell count. four methods g-blup, bayes b,...
This study was conducted to determine the influence of two intermittent (1wk) and abrupt drying off methods on udder health index of dairy cows with 30d dry period. Eighteen multiparous dairy cows were dried off approximately 4 wk prior to the expected calving time in a completely randomized design. For intermittent milk cessation treatment, cows were dried off in the following manner. Milk sam...

mastitis is one of the most serious and costly diseases affecting dairy cattle production. in the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (scc) and subclinical mastitis was investigated in 121 holstein dairy cattle. two alleles of a and b and two genotypes of aa and ab were found in an ecori recognized single nucleotide polymorphism in int...
Abstract One of the latest methods which can improve the accuracy of prediction and response to selection is the selection based on markers. Research has shown that the POU1F1 (Pit-1) gene has important role in the regulation of animal growth and associated with carcass, weight and milk traits. The purpose of this research was to study polymorphisms of POU1F1 gene and their association with...
The objective of this study was to assess the association of polymorphisms in κ-cn, β-lg, β-lg 5′ flanking region, CSN1S2, and IGFBP-3 genes with milk production traits and mastitis-related traits in Chinese Holstein. Traits analyzed were 305 day standard milk yield, protein percentage, fat percentage, the ratio of fat percentage and protein percentage, pre-somatic cell count, somatic cell coun...
power transformers are important equipments in power systems. thus there is a large number of researches devoted of power transformers. however, there is still a demand for future investigations, especially in the field of diagnosis of transformer failures. in order to fulfill the demand, the first part reports a study case in which four main types of failures on the active part are investigate...

The delivery method of [continuous (CONT) vs. every other day or intermittent (INT)] a glucogenic precursor (GP) which was contained glycerin (500 g/kg), mono-propylene glycol (250 g/kg), calcium propionate (150 g/kg), niacin (1 g/kg) and sulfate-Co (350 mg/kg) on performance, selected blood metabolites and liver enzymes were evaluated. Twenty-four multiparous Holstein fresh cows were ...
