13
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)
14
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
15
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
16
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
17
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
