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 کاملUsing Proven Genetics in an AI Program*
Introduction The development of methods to synchronize estrus in beef cattle has been refined to a point that is feasible as well as reasonable to obtain pregnancy rates in mixed populations of cycling and anestrous cows that exceed 50% to a single fixed-time artificial insemination, provided a progestin based estrus synchronization protocol is used (Lamb et al., 2001; Kojima et al., 2002; Perr...
متن کاملUtilization of Genetically Elite Holstein Cows
Merit of service sires for Holstein cows designated as genetically elite for yield in January 1990 was calculated to determine the contribution of these cows to genetic progress. Service sires were determined from sires of registered female progeny because male progeny were selectively registered. Primary data were 1295 elite cows (top 1%) that had a daughter produced from a mating in the 6 mo ...
متن کاملPerspectives for Evaluating Conversational AI
Conversational AI systems are becoming famous in day to day lives. In this paper, we are trying to address the following key question: To identify whether design, as well as development efforts for search oriented conversational AI are successful or not. It is tricky to dene ’success’ in the case of conversational AI and equally tricky part is to use appropriate metrics for the evaluation of c...
متن کاملUsing AI Young Sires in Your Herd: Some Genetic and Economic Considerations
Can we predict what a young sire’s proof will be before he has milking daughters? Afrequent argument made against using a young sire is that we don’t know what his production proof will be until after he has milking daughters. This is not entirely true. AI organizations select young sires for progeny sampling based on pedigree merit. One common measure of pedigree merit is parent average. A bul...
