Application of MACE Proofs for Reliability Improvement of Dairy Sire Selection

Sire selection is one of the most important decisions that a dairy producer makes. It represents a great opportunity to improve the profitability of the dairy production enterprise. This new 3-page fact sheet reviews some key concepts that should be considered in order to make proper selection decisions and discusses alternative methods for selecting sires based on multiple traits.

Sire Selection

First, second, and third lactation Ontario Record of Performance (ROP) 305-day milk records were analyzed separately to evaluate 246 Holstein sires. Second and third lactation records were analyzed with and without adjustment for realized selection intensity of each bull’s daughters on the basis of first lactation yield. The magnitude of adjustments for selection was small, but adjusted records gave sire proofs for second and third lactations that had a variance similar to proofs based on first lactation records. Proofs using adjusted records were more highly correlated with first lactation proofs and with percentage survival figures. One bull out of six significantly reranked on the basis of second or third lactation proofs compared to first lactation proofs. There possibly exists a sire by age of daughter interaction, but the size of the interchange does not warrant an immediate change in sire evaluation procedures or artificial insemination organization sire selection programs.

Reliability Improvement

Abstract A new approach to reliability improvement and failure analysis on ICs is introduced, involving a specifically developed tool for Topography and Deformation Measurement (TDM) under thermal stress conditions. Applications are presented including delamination risk or bad solderability assessment on BGAs during JEDEC type reflow cycles.
