Enhanced Nutritional Support with B Vitamins for Calves Across the Uniblock Bucket Range

Supporting Calves Through the Challenges of Summer Grazing

B vitamins for calves can provide valuable nutritional support during summer grazing, particularly when dietary changes or digestive challenges place rumen function under pressure. Lush, fast-growing grass, low fibre intake and periods of digestive upset can contribute to loose dung, inconsistent thrive and reduced performance—symptoms commonly associated with summer scour.

Recognising these seasonal challenges, Uniblock has enhanced its calf bucket range with protected Vitamin B1 (thiamine), high-level Vitamin B12 and complementary B vitamins.

Protected Vitamin B1 and Vitamin B12 are now included across the Vitulix, Calf to Beef, Copper 5-a-Day and Beef Booster buckets, providing additional nutritional support during periods when rumen function may be under pressure and the natural production of B vitamins may not fully meet the calf’s requirements.

Why Are B Vitamins Important for Calves?

Unlike young calves, mature cattle rely on the microbes within a fully functioning rumen to produce many of the B vitamins required for normal health and performance.

However, calves undergoing the transition to grazing are still developing their rumen. During periods of digestive disturbance, dietary change or reduced feed intake, microbial production of these essential vitamins may be compromised.

Providing supplementary B vitamins during these periods helps support normal metabolic processes and overall calf performance.

The Role of Protected Vitamin B1 for Calves

Vitamin B1 (Thiamine) plays a vital role in:

· Supporting normal rumen function

· Energy metabolism

· Carbohydrate utilisation

· Nervous system health

During digestive stress, thiamine availability may be reduced due to increased degradation within the rumen. By supplying protected Vitamin B1, the Uniblock range helps provide a more reliable source of thiamine when calves need it most.

How Vitamin B12 Supports Calf Performance

Vitamin B12 works alongside Vitamin B1 to support:

· Efficient energy release from feed

· Protein metabolism

· Red blood cell production

· Growth and vitality

Although rumen microbes normally synthesise Vitamin B12, production may be reduced when rumen activity is impaired. Supplementation helps ensure calves continue to receive this essential nutrient during challenging periods.

A Complete B Vitamin Package

In addition to protected Vitamin B1 and high-level Vitamin B12, the enhanced formulation also contains:

· Vitamin B5 (Pantothenic Acid) – supports energy metabolism and nutrient utilisation.

· Vitamin B6 (Pyridoxine) – contributes to protein metabolism and immune function.

· Niacinamide (Vitamin B3) – supports efficient energy production and healthy digestive function.

Together, these vitamins provide a comprehensive package designed to support calves when nutritional demands are increased.

Supporting Calves During Summer Scour Challenges

Summer scour is influenced by a combination of factors, including:

· Rapid changes in diet

· Lush, high-moisture grass

· Low fibre intake

· Developing rumen function

· Weather-related grazing stress

While no nutritional supplement can prevent summer scour, ensuring calves receive an adequate supply of essential B vitamins can help support normal rumen function and metabolism during these periods of challenge.

Maintaining good nutritional status allows calves to continue making the best use of available nutrients while supporting growth and overall resilience.

Now Included Across the Uniblock Calf Bucket Range

This nutritional enhancement is now included as standard in:

· Vitulix

· Calf to Beef

· Beef Booster

Each product has been formulated to provide calves with protected vitamins and minerals in a highly palatable, easy-to-use bucket, ensuring consistent intake throughout the grazing season.

Supporting Performance Throughout the Grazing Season

Good grazing management remains the foundation of healthy calf performance, but nutritional support can play an important role during periods of digestive challenge.

By incorporating protected Vitamin B1, high-level Vitamin B12 and complementary B vitamins across the Uniblock calf bucket range, farmers can provide calves with essential nutrients that help support rumen function, energy metabolism and performance when natural vitamin production may be under pressure.

Targeted Nutritional Support for Calves

Whether calves are adapting to grass for the first time or experiencing periods of digestive stress during the summer months, the addition of a new protected B vitamin formulation to the Uniblock calf bucket range provides targeted nutritional support for calves during periods when rumen function is under pressure, such as during the transition to grass and other digestive challenges.
