This column brings you information regarding some of the research being done around the world and published in the Journal of Dairy Science. It discusses dairy producers' perception of barriers surrounding educational programs and how using time-temperature recorder data on dairy farms can identify short-term factors that increase free fatty acids in the bulk tank.

Researchers assessed the effects of municipal tap water compared with purified water on calf performance and health.

This column brings you information regarding some of the research being done around the world and published in the Journal of Dairy Science. It discusses how lung ultrasonography is improving our understanding and management of respiratory disease in young calves, and the effect of voluntary waiting period length on milk yield, fertility and culling in high-yielding, second-parity cows.

This article, written by researchers from the University of Wisconsin, explores various applications of artificial intelligence (AI) technologies in dairy farming, including the use of computer vision systems (CVS) for animal identification, body condition score (BCS) and body shape analysis, and potential uses of large language models (LLM) in the dairy industry. 

This article from researchers from the University of Guelph and Prince Edward Island describes a study which objectives were to understand awareness, perceptions and barriers to implementation of established best management practices (BMPs) for early detection and treatment of lameness of participant dairy farms.

A look at two published studies in the Journal of Dairy Science that explore employee onboarding and the perceived risk of Salmonella Dublin on Canadian dairy farms.

This article, from researchers from the University of Montreal and Lactanet, aimed at quantifying the impact and disability weight (DW) of frequent diseases or syndromes of preweaning dairy calves using the perceptions of producers and veterinarians.

This article, from researchers from Michigan University and DeLaval, aimed to assess the impact of a training session on dairy farmworkers’ understanding of the milking routine, behavioural changes during milking and subsequent effects on milk quality and udder health.

This article from researchers from Ohio State University describes an experiment conducted to identify the factors that cause reduced production of cows fed a diet with high content of corn distillers grain with solubles (DDGS).
