(Co)variance components for final score and 15 linear types traits of Jersey cows were estimated by multitrait REML using multiple diagonalization and a repeatability model with 34,999 records of 22,354 cows. Multiple diagonalization gave relative off-diagonals (ratio of squared off-diagonals to the product of diagonals) of < 0.1%. Heritabilities and repeatabilities, respectively, were estimate...

Genetic evaluations of Holstein bulls for mean somatic cell score were compared with their standardized transmitting abilities for linear type traits. Based on first lactation daughter information from five dairy records processing centers, PTA for somatic cell scores for 712 sires ranged from -.50 to .56. Standardized transmitting abilities for 14 type traits were provided for these bulls by t...

A granddaughter design was used to locate quantitative trait loci determining conformation and functional traits in dairy cattle. In this granddaughter design, consisting of 20 Holstein Friesian grandsires and 833 sons, genotypes were determined for 277 microsatellite markers covering the whole genome. Breeding values for 27 traits, regarding conformation (18), fertility (2), birth (4), workabi...

genetic and phenotypic parameters related to production traits, udder conformation and somatic cell count for the iranian holstein cows were estimated. monthly records of somatic cell counts (scc) were primarily transformed into somatic cell scores (scs) and the the average level of lactation period, with correction for milk volume, was calculated. by use of these estimates an udder health inde...

The present study was performed to study the genetic relationship of productive life with production and type traits of Korean Holsteins at first three lactations. The data for the analysis from 56,054, 28,997, and 11,816 animals of first, second and third parity cows which were born from 2006 to 2011 were collected by Dairy Cattle Improvement Center, National Agricultural Co-operative Federati...

The study examined the relationship between milk yield and udder morphology traits in White Fulani cows. Fifty-eight apparently healthy cows early lactation at 2nd, 3rd, 4th parity were used study. data obtained from test day (TDMY) single milking comprising length (UL), width (UW), depth (UD), fore teat (FTL), rear (RTL), diameter (FTD), (RTD). There was no significant effect of on TDMY or tra...

This research aims to comprehend the different colostrum production between fore and rear teats of FHC dairy cows. The method used was a case study by observing collecting data at farm purposive sampling. materials in this were 41 postpartum cows that produce on days 1-4 with lactation period 1-5. tabulated analyzed using paired t-test. results showed average 6.40 ± 5.39 kg/cow/day 7.03 5.92 hi...

A study in response to findings the Black, Asian and Minority Ethnic (BAME) students enrolled on education courses at a Northern University, are over-represented Fitness-to-Practice (FTP) investigations. Referrals FTP intended rectify underperformance of students. As phenomenon, it replicates trends across workplace, explained by capital, racial discomfort structural inequality.&amp;nbsp;In thi...

Linear type scoring is key component in decision making process the herd, as it focusses on selection of animals with higher productive potential based their body conformation/linear traits. The present study was carried out 150 lactating Sahiwal cattle first to fifth parity. Measurements linear traits were recorded 1 h before evening milking at three different stages lactation. average score p...
