What is he best known for?

The fields of study he is best known for:

  • Animal science
  • Agronomy
  • Food science

Frank P. O'Mara mainly investigates Dry matter, Animal science, Lactation, Dairy cattle and Food science. His Dry matter study is concerned with Agronomy in general. His Animal science research includes elements of Rumen, Endocrinology, Coconut oil and Forage.

His Dairy cattle research includes a combination of various areas of study, such as Ice calving and Feces. His Food science research is multidisciplinary, incorporating perspectives in Excretion, Low protein, Urine and Pasture. The study incorporates disciplines such as Urea, Randomized block design, Livestock, Animal product and Grazing in addition to Pasture.

His most cited work include:

  • Greenhouse gas mitigation in agriculture (1545 citations)
