Considerations for offering acidified milk

Feeding calves milk is fundamental to their growth and health. This article explores the benefits of feeding cold acidified milk, providing a practical solution for optimizing feeding practices.

Introduction to acidified milk

To acidify milk or milk replacer, follow a protocol developed with your nutritionist or herd veterinarian to add acids (like formic or citric) and lower the pH. When done correctly, the acidified milk will be suitable for room temperature storage, with pH ranging from 4.0 to 4.5, which helps keep bacterial growth in check.

Benefits of feeding acidified milk

1. Bacterial control: Acidifying milk inhibits harmful bacteria such as E. coli, Salmonella, and Staphylococcus, reducing infection risks and improving calf health.
2. Extended storage: Acidified milk can be stored at room temperature for up to three days without significant bacterial growth, which is beneficial in group housing systems where milk is provided ad libitum.
3. Improved digestive health: Acidified milk contributes to better fecal consistency and reduced scours (diarrhea) in calves, due to a more stable pH environment in the digestive tract.
4. Ease of management: Feeding acidified milk simplifies the process as it does not require heating, saving time and reducing labour costs.
5. Calf adaptation: Calves can adapt to drinking cold milk without adverse effects. Studies show no significant differences in growth or health between calves fed cold milk and those fed warm milk if the milk is consistently available.

Effects on digestion

Cold acidified milk slows the rate at which milk exits the abomasum and enters the small intestine, aiding nutrient absorption. This slower passage allows the digestive system more time to process nutrients, enhancing calf health.

Feeding systems

Utilizing insulated containers or specialized feeding systems is an effective strategy to maintain the milk at a stable temperature, regardless of the weather conditions. In both hot and cold climates, insulated containers help ensure that the milk remains at an optimal temperature, preventing it from freezing in cold weather or spoiling in hot weather.

By keeping the milk at a consistent temperature, insulated containers not only enhance the safety and quality of the milk but also contribute to the overall health and well-being of the calves. This approach simplifies the feeding process and ensures that the calves receive milk that is both safe and nutritious, regardless of external temperature fluctuations.

Temperature management

In colder climates, monitor milk temperature to prevent freezing. Extremely low temperatures can make it difficult for calves to drink and may lead to hypothermia. Regularly check milk temperature and quality to ensure it remains safe for consumption.

Practical tips for implementation

To implement an acidified milk feeding program, focus on equipment, consistency, and monitoring. Use well-maintained equipment, maintain a consistent feeding schedule, and regularly monitor calf health. These practices support the overall well-being of the calves.

Conclusion

Feeding calves acidified milk can be beneficial for managing calf health and nutrition, especially in group housing systems. It controls bacterial growth and extends the storage life of milk, improving calf health and reducing digestive issues. Proper preparation methods and potential risks should be considered to ensure the best outcomes for calf rearing.
