While there are no proven vaccines or products for the control of the highly pathogenic avian influenza (HPAI), sound immunity is a core component of the cow’s physiology and ability to produce efficiently and economically. A sound nutrition program supports immunity in both the long and short term and certainly will have positive effects on reducing HPAI incidence. 

A cow’s plane of health and nutrition can have a lasting and profound impact on her offspring throughout their lives, too.

As calving season progresses, we hear of miracle remedies that will get an unthrifty calf up to snuff in no time. Whether oral or injectable, it’s good to understand what the active ingredient in the “cocktail” is that may – or may not – give the calf a boost.

Not all milk replacers are the same. Sure, they differ by protein source, level of protein/fat and any medications or additives included. But milk replacers also differ on how well they support gut health and protect overall calf health. While you probably have a favorite milk replacer, new research shows that adding IgY, the avian equivalent of IgG (immunoglobulin G found in colostrum), can make a good milk replacer even better.

Most veterinarians recommend vaccinating nursing calves against clostridial, respiratory and digestive pathogens at 2 months old to bolster immunity against those pathogens.

A new era of calf prices begs the question: What’s one more worth? An extra weaned calf can be a result of improved reproductive success in conjunction with reducing morbidity and death loss.

Stress on cattle is inevitable, but producers know the goal is to manage and mitigate the stresses animals experience, including transportation, weaning, parturition, dietary and nutritional changes, predation, commingling, vaccination, diseases and infections. 

Ensuring the health and productivity of starter cattle is a complex challenge. One of the critical aspects of managing this is understanding and supporting their immune systems, especially during the stressful transition from pasture to backgrounder or feedlot.

University of Missouri researchers have created the first-ever vaccine proven to protect cattle from bovine anaplasmosis, a tick-borne cattle disease. The disease infects the red blood cells of cattle and causes millions of dollars in economic losses across the U.S. due to reduced cattle production, treatment costs and animal deaths.
