Artificial intelligence (AI) was developed to distinguish cattle by their muzzle patterns and identify early cases of disease, including infectious bovine keratoconjunctivitis (IBK). It was tested on 870 cattle in four locations, with 170 developing IBK. The AI identified 169 of the 170 cases prior to their identification by veterinarians, and another 17 cases that remained free of IBK signs (sensitivity = 99.4%, specificity = 97.6%). These results indicate the AI can detect emerging IBK cases by muzzle images very early in the disease process and be used as an intervention tool in the prevention of IBK outbreaks.

The purpose of this study was to investigate the evolution of digit health (DH) on Swiss dairy farms participating in a nationwide DH program and to identify risk factors associated with poor DH. Specially trained claw trimmers recorded disorders of the digits (DOD) electronically during routine trimmings between January 2020 and June 2023. The first part of the study was a non-randomized controlled implementation study, comparing the evolution of DH in 75 herds that received professional on-farm risk assessments as well as veterinary advice with 49 herds that did not.

Bovine tuberculosis is an important zoonotic infectious disease that presents a risk to human health, livestock, and wildlife. We report the complete genome sequence of a new strain that caused a bovine tuberculosis outbreak on a cattle farm in Saskatchewan, Canada, in 2023.

Brucellosis is a neglected infectious disease caused by animals and is becoming a public health problem in developing countries. There are limited case reports of human brucellosis in Indonesia because the symptoms are not specific. This study investigated the association between serological tests for brucellosis among workers and their knowledge, attitude, and behavior.

Bovine viral diarrhea virus (BVDV), a pestivirus in the family , is a major livestock pathogen. Horizontal transmission leads to acute transient infections via the oronasal route, whereas vertical transmission might lead to the birth of immunotolerant, persistently infected animals. In both cases, BVDV exerts an immunosuppressive effect, predisposing infected animals to secondary infections.

Bovine colostrum (BC), the first milk secreted by mammals after birth, is a trending alternative source for supplementing infants and children, offering benefits for gut and immune health. Its rich components, such as proteins, immunoglobulins, lactoferrin, and glycans, are used to fortify diets and support development. Preterm development is crucial, especially in the maturation of essential systems, and from 2010 to 2020, approximately 15% of all premature births occurred at less than 32 weeks of gestation worldwide.
