The involvement of the pathogenic Shiga-toxin-producing Escherichia coli (STEC; also called verocytotoxic-producing E. coli or VTEC) in sporadic cases and disease outbreaks is presently increasing. Infrequent cases are due to ingestion of milk and dairy products. As ruminants are healthy carriers of STEC and most dairy products may provide these bacteria with favourable conditions for their gro...

Efficient reproduction is important for optimal profitability on dairy operations. Unfortunately, most dairy farms do not attain optimal reproduction due to many factors related to management, health, and physiology of high-producing dairy cows. The physiology issues involved in reproduction of lactating dairy cows are complex but increasingly, the interactions between nutrition, the hormonal s...

D (Dairy Herd Improvement Association) records are an essential part of dairy herd management for many progressive dairy operations. The old adage “If you can’t measure it, you can’t manage it” holds true when it comes to dairy farm management, particularly when it comes to somatic cell count (SCC) management. When working with dairy farmers, we often hear the statement “I don’t know how I woul...

One of the primary objectives of dairy producers is to promote dry matter intake (DMI) to support milk production. Considerable research to date has focused on improving the DMI of lactating dairy cows by changing the nutrient composition of feeds. However, the DMI of group-housed lactating dairy cows is also affected by feeding behavior, which is modulated by the environment, management, healt...

BACKGROUND Inadequate consumption of dairy products without appropriate dietary substitution may have deleterious health consequences. Social research reveals the factors that may impede compliance with dietary recommendations. This is particularly important given the recent introduction of functional dairy products. One of the challenges for public health professionals is to demonstrate the ef...
