TLDR
The ability to produce a bull that is desired by the dairy farmers is imperative for the survival of breeding companies and selection has been based solely on phenotypic information analysed with sophisticated statistical models.Abstract:
INTRODUCTION Each year over 7000 bulls are progeny tested throughout the world. At an approximate cost of US$30,000 per bull this amounts to an overall cost of approximately US$200 million per year. With this amount of expenditure the ability to produce a bull that is desired by the dairy farmers is imperative for the survival of breeding companies. Traditionally selection has been based solely on phenotypic information analysed with sophisticated statistical models. In recent years the phenotypic information has been complemented, to a small degree, by molecular information.read more

Genomic Selection in Dairy Cattle: The USDA Experience.
TL;DR: The integration of DNA marker technology and genomics into the traditional evaluation system has doubled the rate of genetic progress for traits of economic importance, decreased generation interval, increased selection accuracy, reduced previous costs of progeny testing, and allowed identification of recessive lethals.

A High Throughput Single Nucleotide Polymorphism Multiplex Assay for Parentage Assignment in New Zealand Sheep
Shannon M. Clarke,HM Henry,Ken G. Dodds,Timothy W. D. Jowett,Tim R Manley,Rayna M. Anderson,John C. McEwan +6 more
TL;DR: A high throughput SNP assay for use in the New Zealand sheep industry that gives accurate pedigree assignment and will allow a reduction in breeder input over lambing and the SNP test’s suitability for paternity testing is developed.

Effects of pedigree errors on the efficiency of conservation decisions

TL;DR: It is recommended that pedigree registration include whether missing parents are either true founders or non-founders, and the population structure and type of errors should be taken into account before applying optimal contributions.

The number of single nucleotide polymorphisms and on-farm data required for whole-herd parentage testing in dairy cattle herds.
TL;DR: Through simulation and empirical data, a 40-SNP panel was shown to be a comparable or better diagnostic tool than the current 14-microsatellite panel that is used to parentage test New Zealand dairy animals.

Udder Health Shows Inbreeding Depression in Danish Holsteins
TL;DR: The purpose of this study was to estimate inbreeding depression for udder health using records on mastitis incidence and somatic cell count, and three traits, CM1, CM3, and SCC, showed a nonlinear relationship between phenotype and inbreeding coefficient.
