2002 journal article
Heritability of changes in genetic evaluations of dairy bulls from first to later records of daughters
JOURNAL OF DAIRY SCIENCE, 85(4), 951–957.
author keywords: change in evaluations; heritability
MeSH headings : Animals; Breeding; Cattle / genetics; Dairying; Fats / analysis; Female; Lactation / genetics; Male; Milk / chemistry; Milk Proteins / analysis
TL;DR:
Investigation of changes in predicted transmitting abilities (PTA) of yields from evaluations based on first records to evaluationsbased on first and later records of daughters and whether these changes are heritable found them to be heritable.

2002 journal article
Prediction of most recent evaluations of Holstein bulls from first available pedigree information
JOURNAL OF DAIRY SCIENCE, 85(3), 670–676.
author keywords: genetic evaluations; pedigree selection; prediction
MeSH headings : Animals; Breeding; Cattle / genetics; Female; Insemination, Artificial / veterinary; Lipids / analysis; Male; Milk / chemistry; Milk Proteins / analysis; Pedigree; Predictive Value of Tests; Regression Analysis
TL;DR:
Predicting most recent evaluations of young bulls entering artificial insemination sampling programs from pedigree information available at time of sampling indicates that AI organizations put different emphasis on PTA of sire in selection of sons for fat and protein.

2002 journal article
Proven and young Holstein: Bulls compared for daughter yields, productive life, somatic cell score, and inbreeding
JOURNAL OF DAIRY SCIENCE, 85(3), 665–669.
author keywords: daughter deviations; proven bulls; young bulls
MeSH headings : Age Factors; Animals; Breeding; Cattle / genetics; Cell Count / veterinary; Female; Inbreeding; Insemination, Artificial / veterinary; Male; Milk / cytology; Pedigree
TL;DR:
Inbreeding was consistently higher for daughters of young bulls than for those of proven bulls, and results indicate that young bulls were competitive with proven bulls.

2002 journal article
Relationships of productive life evaluations with changes in evaluations for yields
JOURNAL OF DAIRY SCIENCE, 85(3), 677–681.
author keywords: correlations; predicted transmitting abilities; productive life
MeSH headings : Animals; Breeding / statistics & numerical data; Cattle / genetics; Female; Insemination, Artificial / veterinary; Lipids / analysis; Male; Milk / chemistry; Milk Proteins / analysis; Pedigree; Predictive Value of Tests; Regression Analysis
TL;DR:
Correlation analyses showed that changes in AI bull evaluations for yields could improve prediction of productive life for little cost and increases in PTA for yield traits as daughters aged corresponded with longer productive life.

2000 journal article
Genetic change in milk, fat, days open, and body weight after calving based on three methods of sire selection
JOURNAL OF DAIRY SCIENCE, 83(6), 1359–1363.
author keywords: genetic change; index; evaluated sires; young bulls
MeSH headings : Animals; Body Weight / genetics; Breeding; Cattle / genetics; Cattle / physiology; Female; Lactation / genetics; Linear Models; Lipids / analysis; Male; Milk / chemistry; Milk / physiology; Selection, Genetic; Time Factors
TL;DR:
Three Holstein lines, were compared, based on different methods of sire selection, for genetic change in 3.7% FCM, fat yield, days open, and predicted body weight after calving.

2000 journal article
Genetic parameters and trends of milk, fat, days open, and body weight after calving in North Carolina experimental herds
JOURNAL OF DAIRY SCIENCE, 83(6), 1364–1370.
author keywords: genetic correlations; genetic trends; selection; heritabilities
MeSH headings : Animals; Body Weight / genetics; Breeding; Cattle / genetics; Cattle / physiology; Female; Lactation / genetics; Lipids / analysis; Male; Milk / chemistry; Models, Animal; North Carolina; Reproduction / genetics
TL;DR:
The results of this study suggest that AI organizations may need to include fertility traits in progeny testing and relax the emphasis on increased body weight in AI organizations.
