Calves over three weeks old may require an additional 100g of milk replacer powder per 10-degree drop in ambient temperature below 10°C. As calves age, gradually increase the powder-to-water ratio to support growth. Monitor temperature fluctuations and adjust feeding amounts accordingly to ensure optimal nutrient intake and prevent digestive issues. Consistent adjustments help maintain health and development throughout the weaning phase.
Transitioning from Milk Replacer to Solid Feed
Start transitioning calves to solid feed after receiving colostrum and transition milk, around three to four days old, to ensure a smooth digestive adaptation and growth.
5.1 When to Start the Transition
Transitioning calves to solid feed should begin after receiving colostrum and transition milk, typically around three to four days old. This allows the digestive system to adapt gradually, reducing the risk of digestive upset and ensuring smooth growth. The process should align with the calf’s natural development and environmental conditions, such as ambient temperature, to optimize health and performance.
The gradual introduction of solid feed alongside milk replacer helps calves develop a robust digestive system. Start by offering small amounts of high-quality starter feed, such as calf grain or hay, alongside milk replacer at around 3-4 days old. Allow the calf to show interest and begin eating solids voluntarily. Increase the proportion of solid feed gradually over weeks, ensuring the calf can digest both sources effectively. Full transition to solids is typically achieved by 8-10 weeks of age, depending on growth and health.
Selecting the Right Milk Replacer Product
