Now is the time to get things prepared for calving to ensure a positive outcome
Ready or not, calving season is just around the corner.
Preparing in advance will position producers to successfully and immediately address the needs of the cow and the calf.
One way to prepare for calving season is to evaluate potential calving locations. Areas should be clean and dry. Consider providing shelters for animals to escape the weather, especially if the calving season will begin in cold weather. However, remember as animals congregate in shelters there can be an increase in disease contamination.
Be prepared if a female presents with calving difficulty. Heifers that labor in Stage 2 of parturition for longer than an hour and cows that labor longer than 30 minutes should be examined immediately. Develop a plan to transport the animal to a veterinary clinic or have excellent onsite facilities to address calving difficulties. In addition, have the truck and trailer hooked up and ready. Early intervention at the first sign of a problem is critical for both calf and dam survival.
Remember to discuss the calving plan with the herd veterinarian. Producers should develop a relationship with their veterinarian well before a 2 a.m. emergency calving call. Due to high demand, many veterinary practices will only accept emergencies from existing clients. Veterinarians can work with producers and their team to develop protocols, so everyone is on the same page when a problem occurs.
Be certain calving equipment is clean, functional, and readily accessible. A producer’s veterinarian can also make suggestions for essentials to include in a calving kit. Items to consider in a calving kit may include:
• Veterinary emergency number in cell phone
• Breeding dates and due dates with associated sire
• Calving book
• Flashlights with batteries
• Ear tags with marker
• Tag applicator
• Iodine for navel
• Catch pen and functional chute
• 5-gallon bucket
• Calf puller in working order
• Obstetrical chains and handles
• Calf sled
• Syringes and needles
• Exam and obstetrical gloves
• Obstetrical lube
• Clean towels
• Straw or hay for bedding
• Esophageal feeder
• Colostrum or colostrum replacer
• Medications prescribed by your veterinarian such as pain medications
• Sorting stick
• Large trash bags
Following delivery, the goal is to see the calf up and nursing as soon as possible. If a calf requires stimulation, especially to breathe, be careful about the approach. Positioning a calf upside down or hanging the hindlegs over a fence is not effective. In fact, it moves all the abdominal organs towards the lungs and applies pressure making it more difficult to expand the ribcage and take a breath. Gently rubbing a piece of hay in the nostrils can be helpful. It may also be worth discussing acupuncture points and other techniques such as the Madigan Squeeze with a veterinarian.
Ideally, a calf should receive colostrum within the first two hours of life. Administering colostrum to calves without a suckle reflex using an esophageal feeder should be done with extreme caution due to the increased risk of aspiration pneumonia.
Milking the dam or maintaining a supply of frozen colostrum are the best options for colostrum replacement. Commercially-prepared colostrum replacer is acceptable if a cow-derived source is not available. If a cow loses her calf during delivery, consider taking the time to milk the cow and freeze the colostrum for future use.
Monitor a calf’s temperature with a rectal thermometer. Inexpensive digital thermometers work well. If a calf’s temperature falls below 100 degrees, gradually raise it. Bring the calf indoors if needed. When used appropriately, warm water baths, blankets and warming boxes are all options. Be careful not to damage the skin of the animal by rubbing too vigorously or placing the animal close to heaters. Do not wash off the odor of amniotic fluid; this helps prevent rejection by the dam. Warm oral or intravenous fluids as advised by a veterinarian can also make a big difference. Once a calf is warm and has been fed colostrum, return it to its mother.
It is important for producers to work with their veterinarian to develop protocols before calving season, this can reduce stress and lead to more successful outcomes if an emergency arises.
