Progeny test for AI-sires based on Held results
In Germany the estimation of breeding values of young boars and sows is based on their own data for daily gain and backfat as well as fulland/or half-sib information on carcase traits. In breeding companies young boars are often tested under test station conditions using individual pens to get information on feed conversion while gilts are raised in groups and tested at 90 kg of weight for life...

متن کاملEstimation of pedigree errors in the UK dairy population using microsatellite markers and the impact on selection.
The proportion of cows in the UK dairy herd whose sires were misidentified was estimated using DNA markers. Genetic marker genotypes were determined on 568 cows (from 168 milk samples and 400 hair samples) and 96 putative sires (from semen samples). The estimated pedigree error rate from the hair samples was 8.8%, and from the milk samples, 13.1%, giving an overall estimate of the error rate of...
متن کاملSelection of Sahiwal Cattle Bulls on Pedigree and Progeny
The objective of the study was to compare ranking of Sahiwal bulls selected on the basis of highest lactation milk yield of their dams with their estimated breeding values (EBVs) using an animal model. Data on 23,761 lactation milk yield records of 5,936 cows from five main Livestock Experiment Stations in Punjab province of Pakistan (1964-2004) were used for the study. At present the young A.I...
متن کاملRelationships among performance, residual feed intake, and product quality of progeny from Red Angus sires divergent for maintenance energy EPD.
Energy expenditure is a physiological process that may be closely associated with residual feed intake (RFI). The maintenance energy (ME(M)) EPD was developed by the Red Angus Association of America (RAAA) and is used as an indicator of energy expenditure. The objectives of this study were to evaluate and quantify the following relationships using progeny of Red Angus (RA) sires divergent for M...
