His primary areas of investigation include Veterinary medicine, Animal science, Virology, Serology and Digital dermatitis. In the subject of general Veterinary medicine, his work in Flock is often linked to Infectious bursal disease, thereby combining diverse domains of study. His primary area of study in Animal science is in the field of Herd.
His work in the fields of Virology, such as Virus, Herpes B virus and Disease reservoir, intersects with other areas such as Fowl cholera. His work in the fields of Serology, such as Direct agglutination test, overlaps with other areas such as Water buffalo. David W. Hird has included themes like Ice calving and Odds in his Digital dermatitis study.
His primary areas of study are Veterinary medicine, Animal science, Herd, Outbreak and Flock. His work in the fields of Cattle Diseases overlaps with other areas such as Livestock. His Animal science research focuses on Odds and how it connects with Odds ratio.
His Herd study integrates concerns from other disciplines, such as Breed, Gynecology and Disease. His studies in Outbreak integrate themes in fields like Transmission and Case-control study. His Flock study combines topics in areas such as Mortality rate and Newcastle disease.
David W. Hird mainly investigates Veterinary medicine, Serology, Herd, Medical education and Water buffalo. The study of Veterinary medicine is intertwined with the study of Isolation in a number of ways. His research integrates issues of Therapeutic effect, Placebo, Brucellosis and Vaccination in his study of Serology.
He interconnects Bayesian probability, Bayes' theorem and Receiver operating characteristic in the investigation of issues within Brucellosis. His study with Herd involves better knowledge in Animal science. His research investigates the connection between Animal science and topics such as Direct agglutination test that intersect with problems in Card agglutination, Agglutination, Brucella, Brucella Infections and Standard plate.
His primary areas of investigation include Veterinary medicine, Serology, Vaccination, Animal science and Direct agglutination test. Veterinary medicine is closely attributed to Isolation in his research. His research on Serology often connects related areas such as Therapeutic effect.
His Vaccination study combines topics from a wide range of disciplines, such as Papillomatous Digital Dermatitis, Dairy cattle, Placebo and Lactation. Specifically, his work in Animal science is concerned with the study of Herd. His Direct agglutination test research includes elements of Gold standard, Brucella Infections and Standard plate.
