| impact of paternity errors in cow identification on genetic evaluations and international comparisons. | the impact of paternity identification errors on us genetic evaluations and international comparisons of holstein dairy bulls for milk, fat, and protein yields was investigated. sire identification was replaced for 11% of holstein cows that were sired by ai bulls and had records in the us database for national genetic evaluations; us evaluations were computed based on those modified pedigrees and compared with official national evaluations. estimated breeding values from the data with introduced ... | 2001 | 11768094 |

| genomic prediction of dry matter intake in dairy cattle from an international data set consisting of research herds in europe, north america, and australasia. | with the aim of increasing the accuracy of genomic estimated breeding values for dry matter intake (dmi) in holstein-friesian dairy cattle, data from 10 research herds in europe, north america, and australasia were combined. the dmi records were available on 10,701 parity 1 to 5 records from 6,953 cows, as well as on 1,784 growing heifers. predicted dmi at 70 d in milk was used as the phenotype for the lactating animals, and the average dmi measured during a 60- to 70-d test period at approximat ... | 2015 | 26188577 |
