The fields of study he is best known for:

  • Biochemistry
  • Endocrinology
  • Metabolism

Ric R. Grummer mainly investigates Endocrinology, Triglyceride, Lactation, Rumen and Dry matter. His research in Endocrinology intersects with topics in Dairy cattle, Animal science and Postpartum period. He interconnects Very low-density lipoprotein, Insulin and Fatty acid in the investigation of issues within Triglyceride.

His Lactation study focuses on Ice calving in particular. Ric R. Grummer focuses mostly in the field of Rumen, narrowing it down to matters related to Neutral Detergent Fiber and, in some cases, Gestation, Dietary Carbohydrates and Propionate. His study looks at the relationship between Dry matter and topics such as Niacin, which overlap with Lipid metabolism, Carbohydrate and Glycogen.

His most cited work include:

  • Lactation (35.00%)

What were the highlights of his more recent work (between 2004-2016)?

  • Endocrinology (55.00%)
  • Animal science (29.00%)
  • NEFA (24.00%)

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

Ric R. Grummer spends much of his time researching Endocrinology, Animal science, NEFA, Fatty acid and Dairy cattle. The Endocrinology study combines topics in areas such as Linseed oil and Latin square. The various areas that he examines in his Animal science study include Ovulation and Ice calving, Lactation.

The study incorporates disciplines such as Postpartum period and Food science in addition to Lactation. His work deals with themes such as Choline, Triglyceride, Rumen, Insulin and Lipolysis, which intersect with Fatty acid. His studies deal with areas such as Motor activity and Dairy industry as well as Dairy cattle.

Between 2004 and 2016, his most popular works were:

  • Reducing dry period length to simplify feeding transition cows: milk production, energy balance, and metabolic profiles. (183 citations)
  • Nutritional and management strategies for the prevention of fatty liver in dairy cattle. (115 citations)
  • Effects of Dry Period Length on Milk Production and Health of Dairy Cattle (102 citations)

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

  • Biochemistry
  • Endocrinology
  • Metabolism

His scientific interests lie mostly in Endocrinology, Animal science, Dairy cattle, Ice calving and Lactation. His study in Fatty acid extends to Endocrinology with its themes. Ric R. Grummer has included themes like Choline and Triglyceride in his Fatty acid study.

His Triglyceride research is multidisciplinary, relying on both Rumen and Animal feed. In his work, Ovulation, Embryo quality and Body weight is strongly intertwined with Artificial insemination, which is a subfield of Ice calving. His Lactation course of study focuses on Postpartum period and Luteal phase, Follicular phase and Corpus luteum.
