Overview

What is he best known for?

The fields of study he is best known for:

  • Internal medicine
  • Pathology
  • Animal science

N. B. Williamson mainly focuses on Herd, Animal science, Veterinary medicine, Dairy cattle and Estrous cycle. His work carried out in the field of Herd brings together such families of science as Mastitis, Lactation and Pregnancy rate. His Animal science research includes elements of Follicle and Ice calving.

His Ice calving study combines topics from a wide range of disciplines, such as Ovulation, Follicular phase, Pasture and Ovary. N. B. Williamson has included themes like Neospora caninum and Abortion in his Veterinary medicine study. His study in Estrous cycle is interdisciplinary in nature, drawing from both Estrus Detection, After treatment and Intramuscular injection.

His most cited work include:

  • A study of oestrous behaviour and oestrus detection methods in a large commercial dairy herd. I. The relative efficiency of methods of oestrus detection. (106 citations)
  • Patterns of follicular development during periods of anovulation in pasture-fed dairy cows after calving (81 citations)
  • Effect of intraruminal monensin capsules on reproductive performance and milk production of dairy cows fed pasture. (66 citations)

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

N. B. Williamson mainly investigates Animal science, Herd, Veterinary medicine, Ice calving and Dairy herds. His Animal science research includes themes of Lameness, Lactation and Pasture. His biological study spans a wide range of topics, including Breed, Milking, Controlled studies and Pregnancy rate.

His research in Veterinary medicine intersects with topics in Mastitis, Neospora caninum, Serology and Inoculation. The various areas that he examines in his Neospora caninum study include Direct fluorescent antibody, Abortion and Gestation. As a part of the same scientific family, he mostly works in the field of Dairy herds, focusing on Herd health and, on occasion, Artificial insemination.

He most often published in these fields:

  • Animal science (47.57%)
  • Herd (32.04%)
  • Veterinary medicine (26.21%)

What were the highlights of his more recent work (between 2008-2020)?

  • Animal science (47.57%)
  • Veterinary medicine (26.21%)
  • Pasture (15.53%)

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

The scientist’s investigation covers issues in Animal science, Veterinary medicine, Pasture, Ice calving and Mastitis. His Animal science research is mostly focused on the topic Dairy cattle. His Dairy cattle study integrates concerns from other disciplines, such as Milking and Lameness.

His Veterinary medicine research incorporates elements of Neospora caninum, Incidence and Crossbreed. His research integrates issues of Inoculation, Serology, Coccidiosis and Direct fluorescent antibody in his study of Neospora caninum. Breed is closely connected to Herd in his research, which is encompassed under the umbrella topic of Pasture.

Between 2008 and 2020, his most popular works were:

  • Efficacy of a Neospora caninum killed tachyzoite vaccine in preventing abortion and vertical transmission in dairy cattle. (49 citations)
  • The incidence and aetiology of clinical bovine mastitis on 14 farms in Northland, New Zealand (34 citations)
  • Culture results from milk samples submitted to veterinary diagnostic laboratories from August 2003 to December 2006 in New Zealand. (27 citations)
