India Emerging Markets Conference, May 2009 (6) Jana Hutchison 2009 Dairy Herd Information (DHI)  Cow data  National DHIA Producer controlled organization Promote accuracy, credibility, and uniformity of DHI records – Farm management decisions – Genetic evaluations  Dairy Records Processing Center 4 DRPCs in the United States Receive field data Process into approved formats

India Emerging Markets Conference, May 2009 (7) Jana Hutchison 2009 DHI statistics (2007)  48% milk recorded through DHI  4.4 million cows 98% fat recorded 95% protein recorded 94% SCC recorded  22,000 herds  200 cows/herd  22,193 lb (10,067 kg)/cow 3.7% fat 3.1% (true) protein

India Emerging Markets Conference, May 2009 (8) Jana Hutchison 2009 Purebred Dairy Cattle Association (PDCA)  Cow and bull data  Maintain purebred herdbooks Pedigree data Classification/type  Calculate breed specific indexes

India Emerging Markets Conference, May 2009 (9) Jana Hutchison 2009 National Association of Animal Breeders (NAAB)  Bull data  Composed of individuals and organizations in the AI industry  Members account for 95% of the dairy cattle semen in the US

India Emerging Markets Conference, May 2009 (13) Jana Hutchison 2009 AIPL mission  Conduct research to discover, test, and implement improved genetic evaluation techniques for economically important traits of dairy cattle and goats  Genetically improve efficiency of dairy animals for yield traits (milk, fat, protein) and non-yield traits that affect health and profitability (longevity, conformation, fertility, calving, and disease resistance)

India Emerging Markets Conference, May 2009 (14) Jana Hutchison 2009 AIPL research objectives 1. Collect genotypes, specifically single-nucleotide polymorphisms (SNPs), and new phenotypes to improve accuracy and comprehensiveness of the national dairy database

India Emerging Markets Conference, May 2009 (15) Jana Hutchison 2009 AIPL research objectives (cont.) 2. Characterize phenotypic measures of dairy practices, and provide the dairy industry with information needed to determine the impact of various herd management decisions on profitability

India Emerging Markets Conference, May 2009 (16) Jana Hutchison 2009 AIPL research objectives (cont.) 3. Improve accuracy of prediction of economically important traits currently evaluated, determine merit and potential for developing genetic predictions for new traits, and investigate methods to incorporate high-density genomic data

India Emerging Markets Conference, May 2009 (17) Jana Hutchison 2009 AIPL research objectives (cont.) 4. Investigate economic value of traits and correlations among them to most efficiently combine evaluations to select for healthy dairy animals capable of producing quality milk at a low cost in many environments
