Calving Season: Best Practices for Success

Calving season is one of the most critical periods in the lifecycle of a cattle operation. It can be a time of great anticipation and excitement, but it also demands careful planning, careful management, and a deep understanding of cattle health and behavior.

As an experienced veterinarian with years of hands-on experience, I aim to provide you with comprehensive insights and best practices to ensure your calving season is both successful and stress-free.

Understanding the Calving Process

Before diving into the best practices, it’s essential to understand the stages of the calving process. Calving can be divided into three stages:

1). Stage One: Preparation

Duration: 2-6 hours

Signs: Restlessness, isolation from the herd, mucus discharge, and swelling of the vulva.

Key Actions: Monitor closely for any signs of distress or prolonged labor.

2). Stage Two: Active Labor

Duration: 30 minutes to 2 hours

Signs: Water bag appearance, visible contractions, and the calf’s feet and head emerging.

Key Actions: Assist only if necessary. Ensure the calf is delivered without excessive force.

3). Stage Three: Expulsion of Placenta

Duration: 2-8 hours

Signs: Placenta should be expelled naturally.

Key Actions: Ensure the placenta is fully expelled. Retained placenta can lead to infections.

Preparing for Calving Season

Preparation is the cornerstone of a successful calving season. Here are some critical steps:

1. Nutrition and Health

Proper nutrition and health management of pregnant cows are crucial. Ensure they are on a balanced diet rich in essential nutrients, especially in the last trimester. Regular health checks and vaccinations help prevent diseases that can complicate calving.

2. Calving Environment

Create a clean, dry, and safe calving environment. Calving pens should be spacious and equipped with clean bedding. Regularly disinfect the area to prevent infections.

3. Monitoring and Record-Keeping

Invest in reliable monitoring systems to keep track of each cow's progress. Maintain detailed records of breeding dates, expected calving dates, and any health issues.

Emergency Calving Kit Essentials

Having a well-prepared emergency calving kit is crucial for addressing unexpected complications. Here’s what you should include:

1. Sterile Obstetric Gloves: To maintain hygiene during assistance.
2. Lubricant: Essential for assisting with difficult births.
3. Calving Ropes and Chains: For safely pulling calves if necessary.
4. Antiseptics and Disinfectants: To clean equipment and the calving area.
5. Syringes and Needles: For administering medications.
6. Colostrum Replacer: For calves that struggle to nurse initially.
7. Calf Resuscitator: To help stimulate breathing in weak calves.

Having these items on hand can make a significant difference in emergencies, ensuring you can respond quickly and effectively.

Managing the Calving Process

When calving begins, follow these best practices to ensure the well-being of both the cow and the calf:

1. Early Detection of Problems

Early intervention can save lives. Be vigilant for signs of distress or complications such as dystocia (difficult birth). If labor extends beyond the typical duration or if the cow shows signs of excessive discomfort, seek veterinary assistance immediately.

2. Assistance During Delivery

If intervention is necessary, ensure it is done correctly. Use clean, sanitized equipment, and follow proper techniques to assist the cow without causing injury. Only assist if you are trained; otherwise, call a veterinarian.

3. Post-Delivery Care

Once the calf is born, ensure it starts breathing and stands up within the first hour. Clean the calf’s airways and monitor its breathing. Ensure the cow bonds with the calf and allows it to nurse, as colostrum intake in the first few hours is vital for the calf’s immunity.

Post-Calving Management

Proper post-calving management is essential to ensure the health of both the cow and the calf.

1. Monitor Health

Watch for signs of post-calving complications such as milk fever, metritis, or retained placenta. Regularly check the cow’s appetite, behavior, and overall condition.

2. Nutrition for the Cow

Provide high-quality feed and fresh water to the cow. Lactating cows have increased nutritional requirements, so ensure their diet supports milk production and recovery.

3. Calf Care

Ensure the calf receives adequate colostrum within the first 12 hours. Monitor its growth, health, and development. Vaccinate according to your veterinarian’s recommendations and implement a deworming schedule.

Handling Orphaned or Rejected Calves

Occasionally, a calf may be orphaned or rejected by its mother. Here’s how to manage such situations:

1. Immediate Care

Provide warmth and ensure the calf receives colostrum within the first few hours. Use a bottle or tube feeding if necessary.

2. Nutritional Support

Transition to milk replacer after the initial colostrum period. Follow recommended feeding schedules and ensure the calf is gaining weight and developing normally.

3. Socialization and Monitoring

Orphaned or rejected calves need additional socialization to ensure they integrate well with the herd later. Regularly monitor their health and development, and provide extra care and attention as needed.

Handling Common Calving Challenges

Even with the best preparation, challenges can arise. Here are some common issues and how to handle them:

1. Dystocia

Dystocia can occur due to various reasons such as a large calf, improper positioning, or maternal health issues. Ensure you are familiar with calving assistance techniques or have immediate access to veterinary help.

2. Retained Placenta

If the placenta is not expelled within 24 hours, it can lead to serious health problems. Consult with a veterinarian for appropriate treatments, which may include medications or manual removal.

3. Weak Calves

Weak calves may struggle to stand or nurse. Provide supplemental colostrum and ensure they are kept warm and dry. Seek veterinary advice for further care strategies.

Emphasizing Animal Welfare

Throughout the calving season, prioritize animal welfare. Stress and discomfort can negatively impact both cows and calves, so ensure a calm, supportive environment. Handle animals gently and minimize disruptions during the critical periods of labor and post-calving.

Conclusion

Calving season is a pivotal time that demands meticulous planning, vigilant monitoring, and expert care. By following these best practices, you can ensure a successful and stress-free calving season, promoting the health and productivity of your herd.

Remember, the key to success lies in preparation, early detection of problems, and prioritizing the welfare of both cows and calves. As an experienced veterinarian, I encourage you to embrace these strategies and continuously seek knowledge to improve your calving practices. Here’s to a prosperous calving season and healthy, thriving cattle!
