It seems like every calving season, there is always a calf or two that fails to get up and nurse. Perhaps the labor was stressful. Maybe the calf is slow to figure things out. Possibly the first-calf heifer is confused and kicks at the calf. Whatever the reason, it’s hard to avoid having to milk out and tube feed a few calves every year.
It’s critical to get colostrum in the calf within 24 hours after birth. This ensures the passive transfer of immunity before the closure of the intestine, which allows the calf to absorb good quality immunoglobulin, explains Michelle Arnold, DVM, University of Kentucky ruminant veterinarian, in a recent article for the Ohio State University Extension Beef Newsletter.
BEEF Roundtable: Considerations for a successful calving season
Arnold says there are four key factors that contribute to the goal of successful passive transfer of immunity and ultimately determine the health and survival of the newborn calf.
Arnold recommends, “Feed a high quality colostrum with a high immunoglobulin concentration (>50 g/L) or use of a good quality powdered colostrum replacer (not a supplement).”
She also suggests, “Feed an adequate volume of colostrum (2 quarts to beef calves at birth followed by 2 more quarts in 4-6 hours).”
She advises producers to, “Feed colostrum promptly after birth (within 1-2 hours and again by 6 hours maximum).”
Finally, she warns, “Passing the tube too quickly may result in damage to the laryngeal area and passage into the trachea and lungs. Handling the calf correctly minimizes this risk.”
To achieve the appropriate quality and quantity as quickly and quietly as possible, she also gives advice on how to properly handle the calf, insert the tube, check placement of the tube, administer the colostrum, remove the tube, and clean the equipment, which you can read here.
Arnold concludes, “Learning to use an esophageal feeder may mean the difference in life or death to a newborn calf. Esophageal feeders can also be used to administer vital electrolytes to scouring calves if reluctant to nurse a bottle.”
She recommends watching the videos below for a complete demonstration on tube feeding a newborn calf.
