Overview

What is he best known for?

The fields of study he is best known for:

  • Statistics
  • Animal science
  • Genetics

H.D. Norman mainly investigates Animal science, Herd, Dairy cattle, Ice calving and Veterinary medicine. His work in the fields of Herd, such as Culling, overlaps with other areas such as Turnover, Time at risk and Standardized approach. The study incorporates disciplines such as Breed, Lactation and Heritability in addition to Dairy cattle.

H.D. Norman interconnects Milking and Biotechnology in the investigation of issues within Heritability. His Ice calving research is multidisciplinary, incorporating perspectives in Pregnancy rate and Longevity. H.D. Norman has researched Pregnancy rate in several fields, including Animal breeding and Artificial insemination.

His most cited work include:

  • Development of a National Genetic Evaluation for Cow Fertility (225 citations)
  • Reproductive status of Holstein and Jersey cows in the United States. (137 citations)
  • Invited Review: Culling: Nomenclature, Definitions, and Recommendations (112 citations)

What are the main themes of his work throughout his whole career to date?

H.D. Norman mainly focuses on Animal science, Herd, Dairy cattle, Sire and Ice calving. His studies in Animal science integrate themes in fields like Veterinary medicine, Artificial insemination and Lactation, Milk yield. His Herd study integrates concerns from other disciplines, such as Test and Parity.

His biological study deals with issues like Heritability, which deal with fields such as Repeatability and Restricted maximum likelihood. His Sire study incorporates themes from Percentile, Regression analysis, Statistics and Biotechnology. His Ice calving research incorporates elements of Pregnancy rate and Longevity.

He most often published in these fields:

  • Animal science (53.95%)
  • Herd (47.37%)
  • Dairy cattle (36.84%)

What were the highlights of his more recent work (between 2006-2017)?

  • Animal science (53.95%)
  • Herd (47.37%)
  • Sire (35.53%)

In recent papers he was focusing on the following fields of study:

His scientific interests lie mostly in Animal science, Herd, Sire, Ice calving and Dairy cattle. His Animal science research includes themes of Veterinary medicine, Biotechnology and Lactation, Milk yield. His Herd study frequently links to other fields, such as Artificial insemination.

His biological study spans a wide range of topics, including Semen, Insemination and Pregnancy rate. His Sire research is multidisciplinary, incorporating elements of Pregnancy, Parity, Statistics, Gynecology and Breed. His research investigates the link between Dairy cattle and topics such as Heritability that cross with problems in Regression analysis and Regression.

Between 2006 and 2017, his most popular works were:

  • Reproductive status of Holstein and Jersey cows in the United States. (137 citations)
  • Use of sexed semen and its effect on conception rate, calf sex, dystocia, and stillbirth of Holsteins in the United States. (97 citations)
  • Genetic and environmental factors that affect gestation length in dairy cattle. (81 citations)
