Calf hydration management is one of the most critical and often overlooked components of successful calf raising. In the first weeks of life, calves are highly susceptible to fluid imbalance caused by environmental stress, management transitions and gastrointestinal illness.

A calf’s gut is a blank slate at birth, but bacterial microbes quickly establish themselves within the first weeks of life. During this narrow window, the calf’s gastrointestinal (GI) tract is rapidly colonized by bacteria from equipment, colostrum and bedding – both beneficial as well as harmful.

In an increasingly demanding dairy production environment, the performance of replacement heifers is a major factor for ensuring herd profitability and sustainability. A solid rearing program goes beyond genetics – it starts with measuring current growth results.

Persistently infected (PI) calves shed bovine viral diarrhea virus (BVDV) with every breath and drop of saliva. They don’t just live with the virus – they spread it, continuously and invisibly, exposing every animal around them to the disease, which can impact overall herd health and performance.

Literally, the first hour of birth sets the stage for a calf’s life. After those 60 minutes, a calf climbs aboard one of three tracks.

Recent research has shown the epigenetic influences of colostrum feeding practices on the long-term productivity and health of dairy cows. This article delves into the importance of timely colostrum feeding and its epigenetic impacts, providing insights for dairy farmers and dairy consultants.
