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.

In a circular economy context, identifying ways to valorize permeate on-farm could represent an interesting opportunity to increase milk production sustainability. But under what conditions is this practice advantageous? And what impact is this likely to have on animal productivity, and on milk composition and its suitability for processing?

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. 

In dairy production and processing, the various surfaces in contact with milk are also conducive to the development of biofilms. Once established, these biofilms can become attractive habitats for undesirable bacteria or moulds, thus affecting the quality and safety of milk.

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.

Dairy Farmers of Canada (DFC) is proud to announce the launch of the new DFC Student Program, a dedicated initiative for students and postdoctoral researchers involved in DFC-funded research projects.

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.
