Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Biochemistry
  • Endocrinology

His primary scientific interests are in Lactation, Weaning, Internal medicine, Endocrinology and Animal science. J. E. Pettigrew performs multidisciplinary study on Lactation and Estrous cycle in his works. His study in Weaning is interdisciplinary in nature, drawing from both Pancreas and Gastric mucosa.

In the subject of general Internal medicine, his work in Hormone, Metabolite and Luteinizing hormone is often linked to Blood urea nitrogen, thereby combining diverse domains of study. As part of one scientific family, he deals mainly with the area of Endocrinology, narrowing it down to issues related to the Lysine, and often Follicular phase and Ovarian follicle. As part of the same scientific family, he usually focuses on Animal science, concentrating on Veterinary medicine and intersecting with Litter and Live weight.

His most cited work include:

  • Effect of age, weaning and diet on digestive enzyme levels in the piglet. (167 citations)
  • Feed intake pattern during lactation and subsequent reproductive performance of sows (97 citations)
  • Characterization of luteinizing hormone secretion in the primiparous, lactating sow: relationship to blood metabolites and return-to-estrus interval. (96 citations)

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

J. E. Pettigrew focuses on Animal science, Lactation, Endocrinology, Internal medicine and Weaning. When carried out as part of a general Animal science research project, his work on Litter is frequently linked to work in Composition and Soybean meal, therefore connecting diverse disciplines of study. His Litter research integrates issues from Body weight and Weight gain.

His study in the field of Insulin, Luteinizing hormone and Hormone also crosses realms of Blood urea nitrogen. His research in Internal medicine intersects with topics in Urea and Digestion. The concepts of his Weaning study are interwoven with issues in Corn oil, Herd, Weanling and Animal feed.

He most often published in these fields:

  • Animal science (60.78%)
  • Lactation (52.94%)
  • Endocrinology (39.22%)

What were the highlights of his more recent work (between 1998-2011)?

  • Lactation (52.94%)
  • Litter (37.25%)
  • Internal medicine (39.22%)

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

J. E. Pettigrew mainly investigates Lactation, Litter, Internal medicine, Endocrinology and Gestation. In his papers, J. E. Pettigrew integrates diverse fields, such as Lactation, Weaning and Weight gain. His work in Weaning addresses subjects such as Meal, which are connected to disciplines such as Animal feed and Estrous cycle.

Animal science covers he research in Litter. In general Internal medicine study, his work on Hormone often relates to the realm of Mammary gland, thereby connecting several areas of interest. His work in the fields of Lysine, such as Lysine intake, overlaps with other areas such as Follicular fluid.

Between 1998 and 2011, his most popular works were:

  • Effects of dietary lysine intake during lactation on blood metabolites, hormones, and reproductive performance in primiparous sows. (71 citations)
  • Impact of dietary lysine intake during lactation on follicular development and oocyte maturation after weaning in primiparous sows. (62 citations)
  • Effect of protein intake during gestation and lactation on the lactational performance of primiparous sows. (60 citations)

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

  • Internal medicine
  • Biochemistry
  • Endocrinology

J. E. Pettigrew mostly deals with Endocrinology, Lactation, Internal medicine, Hormone and Lysine. His Internal medicine study often links to related topics such as Animal science. His research in the fields of Weaning overlaps with other disciplines such as Follicular fluid.

J. E. Pettigrew combines subjects such as Urea and Luteinizing hormone with his study of Metabolism. His Gestation studies intersect with other subjects such as Weight gain, Metabolite and Blood urea nitrogen.
