Less Can Be More: Rethinking Colostrum Feeding for UK Calves

Colostrum remains the calf’s first line of defence. High immunoglobulin (IgG) levels are critical, but achieving and maintaining them depends on multiple factors, including dry cow nutrition, timing of collection, storage temperature, and hygiene.

Preventing bacteria contaminating colostrum and transition milk produced in robotic milking systems

Maintaining colostrum hygiene in robotic milking systems is vital for calf health and immune development. This article explores the risks of bacterial contamination, highlights research findings, and offers best practices for collecting and storing colostrum and transition milk in automated dairy operations.

Management Considerations for Bluetongue Movement Restrictions

Managing calves during Bluetongue movement restrictions requires strict hygiene, proper housing, and strong colostrum protocols. Learn how to protect your herd under movement restrictions.

How to reduce bacterial contamination of colostrum

The awareness and importance of testing and feeding good-quality colostrum has become increasingly popular over the last few years. However, the colostrum storage and handling process is sometimes overlooked [...]

Beef cross calves thrive on two step feeding regime

A two-step approach to calf milk replacer (CMR) feeding has helped a Leicestershire dairy farm cut calf deaths to under 2% and lower the incidence of scour. John Greaves and his family run a herd of 220 all-year-round calving Holstein Friesians at Lodge Farm. It is an 800-acre mixed dairy, beef and arable farm. They […]

Benefits of Feeding Transition Milk for Longer

In a recent survey by Bonanza Calf Nutrition of 153 farmers, it was found that over 57% of the farmers only feed transition milk up to day five of the calf’s life, which aligns with the first 5-6 milkings after colostrum.

Feeding calf milk replacer cuts dairy farm’s GHG emissions and rearing costs

Feeding heifer replacements calf milk replacer (CMR) instead of cow’s milk is allowing a Warwickshire dairy farm to capture environmental and financial wins.

How dairy farmers can unlock the financial potential of beef calves

As market values soar, it has never been a better time to reap the financial rewards of rearing the best calves possible.

Survey demonstrates calf rearers recognise value of transition milk

Growing numbers of farmers are understanding the value of transition milk to the health and future potential of their calves. A recent survey by Bonanza Calf Nutrition found that more than three quarters of the farmers who responded – 94 out of 123 participants – fed transition milk, the highly nutritious and immune-boosting milk produced […]

Factors affecting IgG absorption in the baby calf aside from colostrum

Excellent colostrum management is key when it comes to providing the baby calf with its first source of immunity. But what else can impact the immune status of baby calves? A study conducted by Jones et al. (2004) found the apparent efficiency of IgG absorption ranged from less than 10% to greater than 25% in […]
