🔍 Mineral Spotlight #4 Selenium

Tiny requirement. Major role.

These cows have had access to our Bloc Oligos lick buckets alongside free-choice salt for the past few weeks, and we’re very pleased with how they’re progressing - improving coat condition and shine, healthy body condition, and good muscle development. 🐂🌱

Selenium may only be required in very small amounts, but its role within the animal is significant. Working closely with vitamin E, selenium forms an important part of the body's natural antioxidant defence system, helping to protect cells from oxidative stress.

Good selenium status supports immune function, fertility and reproduction, normal muscle function, healthy growth and development, and calf and lamb vigour.

It can be particularly important during periods of increased demand, such as growth, pregnancy, calving, and other times of physiological stress.

Of course, what we see in our cows isn't down to one mineral alone. Genetics, grass, overall nutrition, health, and good management all work together. Getting the mineral balance right is one important part of that bigger picture.

And with selenium, balance is essential - both deficiency and excessive intake can cause problems, which is why supplementation should always be considered as part of the complete diet and mineral programme.

Healthy on the outside starts with supporting what's happening on the inside.

At Blackfield Agri Nutrition, we believe exceptional livestock performance starts at cell level. 🌱

🔍 Mineral Spotlight #3 - Copper

Copper may be needed only in small amounts, but it plays a major role in livestock health and performance.

It supports immunity, fertility, growth, energy metabolism, connective tissue formation, and healthy coat pigmentation.

However, the amount of copper listed on a mineral label doesn't tell the whole story. The animal must be able to absorb and utilise it, and antagonists such as molybdenum, sulphur, and iron can interfere with copper availability.

That's why both balance and mineral source matter.

In our powder mineral formulations, we use chelated copper as part of our approach to providing highly available trace elements.

⚠️ **A particularly important point for sheep**
Sheep are much more sensitive to excess copper than cattle. Copper can accumulate in the liver and potentially cause serious toxicity, so supplementation must always be species-appropriate and take the complete diet into account.

When it comes to minerals, more isn't always better.

The right mineral. The right amount. The right balance.

🔍 Mineral Spotlight #2 – Salt

When people think about livestock nutrition, they often focus on protein, energy, or minerals like copper and selenium. Yet one of the most important nutrients is often the simplest... salt.

Every cell in your animal's body depends on sodium. It helps regulate fluid balance, allows nutrients to move into cells and waste products to move out, and is essential for nerve signalling, muscle function, and maintaining normal body processes.

As temperatures rise, cattle naturally lose more salt through increased sweating and higher water turnover. If these losses aren't replaced, hydration, appetite, rumen function, and ultimately animal performance can all be affected.

Providing free access to a quality salt block allows cattle to regulate their own intake according to their physiological needs, helping to support:

✔ Hydration and electrolyte balance
✔ Healthy feed intake and rumen function
✔ Muscle and nerve function
✔ Overall health, fertility, and performance

At Blackfield Agri Nutrition, we believe exceptional livestock performance starts long before you see it in the field—it starts at cell level.

Sometimes the simplest nutritional tools make the biggest difference.

💬 Next week in our Mineral Spotlight series: Why copper isn't always copper... and why the source of a mineral matters just as much as the amount.

🔍 Mineral Spotlight #1 – Bloc Oligos 🐂🌱

As grazing season gets underway, ensuring cattle have access to the right minerals is just as important as providing quality grass.

Bloc Oligos is one of the mineral solutions we use to support our cows throughout the grazing season. Designed specifically for grazing cattle, it provides essential trace elements including copper, zinc, manganese, selenium, cobalt, and iodine.

Benefits include:

✔ Supports immunity and overall vitality
✔ Helps maintain healthy skin and resilience
✔ Supports bone and muscle development
✔ Encourages cattle to regulate their own mineral intake
✔ Weather-resistant and ideal for pasture conditions

Good livestock performance starts with strong nutritional foundations, and sometimes the simplest tools can make the biggest difference.

Over the coming weeks we'll be sharing more about minerals, trace elements, and how attention to detail can help maximise livestock health and performance.

Every day starts the same way on our farm: mixing milk for the calves.

And every day, we're reminded that consistency matters.

We carefully measure the milk powder, mix it with water at 55°C, and feed at the ideal drinking temperature of 40–42°C. The process is simple, reliable, and so easy that even our daughter enjoys helping with the preparation. ❤️

What we appreciate most is the consistency of the milk itself. There is no fat separation during mixing, carrying, or feeding. Every litre remains smooth and uniform, ensuring that the nutrients stay where they belong — in the milk and ultimately in the calves.

That means every calf receives the same balanced nutrition from the first mouthful to the last.

The calves certainly seem to agree. Every day they eagerly line up for their milk, and more often than not they're still licking their noses afterwards, searching for those final drops. 😋🐮

And yes, I've tasted it myself. If I'm being honest, it tastes better than some of the baby formula bottles our daughter drank when she was a baby! 😅

For us, good calf nutrition is about more than growth rates and numbers. It's about knowing that every feed is mixed correctly, fed at the right temperature, and delivers all the nutrition the calves need to get the best possible start in life.

Day after day, feed after feed, that's exactly what we see.
