Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Endocrinology
  • Animal science

José E. P. Santos mainly investigates Internal medicine, Endocrinology, Animal science, Estrous cycle and Insemination. In his research, Dairy cattle is intimately related to Artificial insemination, which falls under the overarching field of Internal medicine. His Endocrinology research focuses on Conceptus and how it relates to Docosahexaenoic acid and Polyunsaturated fatty acid.

His Animal science research includes themes of Mastitis and Ice calving, Lactation. The concepts of his Estrous cycle study are interwoven with issues in Ovulation, Follicular phase, Andrology and Pregnancy rate. His study deals with a combination of Insemination and Reproduction.

His most cited work include:

  • The effect of embryonic death rates in cattle on the efficacy of estrus synchronization programs (471 citations)
  • Effects of rumen-undegradable protein on dairy cow performance: a 12-year literature review. (266 citations)
  • Factors affecting conception rate after artificial insemination and pregnancy loss in lactating dairy cows (257 citations)

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

His primary areas of investigation include Animal science, Internal medicine, Endocrinology, Lactation and Artificial insemination.
