Preliminary Report on International Dairy Sire Evaluation Using Individual Performance Records
نویسندگان
چکیده
International genetic evaluation of dairy sires is currently a two-stage process. Sire EBV are first calculated at the national level based on data of local progeny, then these national EBV are combined into international EBV at the Interbull Centre. However, differences in within-country procedures for data collection and genetic evaluation can affect the results, and traits or production environments must be defined according to country borders. Therefore, the objective of this study was to examine the potential for international dairy sire evaluation based on individual animal performance records using raw data collected in participating Interbull member countries.

Relationship between individual herd-heritability estimates and sire misidentification rate.
The objectives of this study were to estimate heritabilities within herds participating in Dairy Herd Improvement and determine the relationship of the individual herd heritability with sire misidentification rate. Individual herd heritabilities for milk, fat, and protein yield and somatic cell score (SCS) were calculated with daughter-dam regression and daughter-sire predicted transmitting abi...
متن کاملA multiple-trait herd cluster model for international dairy sire evaluation.
International dairy sire evaluations have traditionally been calculated using a two-step process. Lactation records within each country are used to predict national estimated breeding values, then these national breeding values are transformed to the genetic base, scale, and units of measurement of other countries by using conversion formulae or the multiple-trait, across-country evaluation met...

A joint sire and cow evaluation for selected type traits has been carried out for the Canadian Holstein population using an individual animal model accounting for all known relationships. Only first lactation, first classification linear records were utilized. Linear scores for final class/final score (combined), feet and legs, mammary system, and stature were analyzed. The model of analysis in...
متن کاملSire Evaluation by Only Extended Partial Milk and Fat Records
The standard of comparison for dairy production records is the 305-day lactation, and much research has been directed to estimating 305-day milk and fat records from incomplete or in-progress records. This study was to determine the effect of several methods of extending incomplete records on sire evaluation. Complete 305-day milk and fat records of first lactations of 73,724 daughters of 1,362...
