🐄 Sometimes a calf needs a little extra help getting started after delivery! In this video, Dr. Pospisil will cover the basics of reviving a newborn calf including positioning, clearing the airway when needed, and stimulating the calf to encourage breathing.

Knowing how to respond when a calf isn’t breathing normally can make a difference in those critical first moments. 🫁❤️

⚠️ If a calf isn’t breathing or is only gasping, seek immediate veterinary assistance. Avoid hanging calves upside down, as this can interfere with breathing.

🐮 What do you need to know before assisting with a cow’s calving? In this video, Dr. Pospisil will cover the supplies you’ll need, the basics of palpating to assess calf presentation, what a normal presentation should feel like, and how to appropriately assist during delivery.

Knowing what’s normal, having the right supplies ready, and recognizing when to call your veterinarian can make a big difference for both the cow and calf! 🐄

⚠️ Always use proper hygiene and plenty of obstetrical lubricant. If the calf’s position is abnormal, delivery isn’t progressing, or you’re unsure how to proceed, contact your veterinarian. Improper manipulation or pulling can injure both the cow and calf.

🐮 Assisting with a difficult calving? Knowing how to properly place OB chains is an important step of safe calf delivery! In this video, Dr. Pospisil demonstrates proper chain placement and how to use them when assisting with calving.

Proper placement and technique help distribute pressure more evenly and reduce the risk of injury.

⚠️ Always assess calf presentation and position before pulling. Use appropriate technique, and contact your veterinarian if the calf is malpositioned, delivery isn’t progressing, or you’re unsure how to proceed.

🐮 The 3 Stages of Labor in Cattle 🐄

Calving doesn’t happen all at once! Understanding the 3 stages of labor can help you recognize normal progress and know when a cow or heifer may need assistance.

🐄 Stage 1: Cervical Dilation: The cervix begins to dilate, contractions start, and the cow may become restless, separate from the herd, or show signs of discomfort.

🐄 Stage 2: Delivery of the Calf: The calf moves through the birth canal and is delivered. This is the stage when you’ll see active straining and the appearance of the water bag or calf’s feet.

🐄 Stage 3: Passage of the Placenta: After the calf is born, the cow passes the fetal membranes (placenta).

⏰ Remember: Every calving is different, but knowing what to expect can help you recognize when things aren’t progressing normally. When in doubt, contact your veterinarian! 🩺
