Overview

What is he best known for?

The fields of study he is best known for:

  • Agronomy
  • Ecology
  • Animal science

His primary areas of study are Ice calving, Dry matter, Grazing, Animal science and Agronomy. His Dry matter research includes elements of Randomized block design, Dairy cattle and Organic matter. His Grazing research incorporates elements of Agroforestry, Animal product and Temperate climate.

While the research belongs to areas of Animal science, he spends his time largely on the problem of Pasture, intersecting his research to questions surrounding Rumen. Michael O'Donovan has included themes like Concordance correlation coefficient and Agricultural science in his Agronomy study. His Perennial plant study integrates concerns from other disciplines, such as Cultivar, Casein and Raw milk.

His most cited work include:

  • Microbiome analysis of dairy cows fed pasture or total mixed ration diets (169 citations)
  • Effect of restricted access time to pasture on dairy cow milk production, grazing behavior, and dry matter intake (94 citations)
  • Effect of pasture versus indoor feeding systems on raw milk composition and quality over an entire lactation. (72 citations)

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

Michael O'Donovan spends much of his time researching Grazing, Agronomy, Dry matter, Animal science and Pasture. His Grazing study combines topics in areas such as Livestock, Stocking, Lactose and Milk production. His work focuses on many connections between Agronomy and other disciplines, such as Organic matter, that overlap with his field of interest in Randomized block design.

His study in Dry matter is interdisciplinary in nature, drawing from both Silage, Dairy cattle, Tiller, Rumen and Yield. His Animal science research is multidisciplinary, incorporating elements of Feed conversion ratio, Energy balance and Heritability. Michael O'Donovan has researched Pasture in several fields, including Raw milk and Yield.

He most often published in these fields:

  • Grazing (50.00%)
  • Agronomy (48.39%)
  • Dry matter (42.74%)

What were the highlights of his more recent work (between 2016-2021)?

  • Animal science (40.32%)
  • Pasture (25.81%)
  • Grazing (50.00%)

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

Michael O'Donovan spends much of his time researching Animal science, Pasture, Grazing, Agronomy and Perennial plant. The concepts of his Animal science study are interwoven with issues in Energy balance and Raw milk. Within one scientific family, Michael O'Donovan focuses on topics pertaining to Concordance correlation coefficient under Pasture, and may sometimes address concerns connected to Grassland management.

His research in Grazing focuses on subjects like Livestock, which are connected to Significant difference and Productivity. His work in Perennial plant covers topics such as Cultivar which are related to areas like Milk production, Spring and Yield. His work carried out in the field of Yield brings together such families of science as Ruminant, Dry matter and Silage.

Between 2016 and 2021, his most popular works were:

  • PastureBase Ireland (59 citations)
  • Original papersPastureBase Ireland: A grassland decision support system and national database (44 citations)
  • Outdoor grazing of dairy cows on pasture versus indoor feeding on total mixed ration: Effects on gross composition and mineral content of milk during lactation. (31 citations)

In his most recent research, the most cited papers focused on:

  • Ecology
  • Agronomy
  • Botany

His scientific interests lie mostly in Pasture, Agronomy, Animal science, Concordance correlation coefficient and Mean squared prediction error. Among his Pasture studies, there is a synthesis of other scientific areas such as Total dissolved solids and Ice calving. His study in the fields of Yield, Lolium perenne and Grazing under the domain of Agronomy overlaps with other disciplines such as Total mixed ration.

Michael O'Donovan combines subjects such as Ruminant, Perennial plant, Dry matter and Silage with his study of Yield. His Animal science research incorporates themes from Biotechnology and Energy balance. Michael O'Donovan has included themes like Grassland management and Grassland in his Concordance correlation coefficient study.
