How Phosphorus powers your dairy herds health and productivity
In the world of dairy farming, there’s one dietary nutrient that takes centre stage: phosphorus. From sturdy bones to abundant milk production, phosphorus is an unsung hero that quietly powers your cows health and productivity.
In this article, we delve into the world of phosphorus and explore why it is so important for your dairy cattle.
1. Strong Bones and Hooves
Phosphorus is the foundation of bone and hoof health. Just as a sturdy frame supports a building, phosphorus supports your cows’ skeletal structure. It ensures bones remain robust, reducing the risk of fractures and disorders like osteoporosis. Moreover, it’s the key to strong hooves, preventing lameness, stress and discomfort in your herd.
2. Energy Metabolism
Think of phosphorus as the fuel for your cows’ engines. It’s a fundamental component of adenosine triphosphate (ATP), the molecule responsible for storing and transferring energy within cells. When your cows need to walk, chew cud, or produce milk, it’s phosphorus that powers these activities.
3. Reproductive Health
Phosphorus doesn’t stop at physical health; it’s essential for reproduction too. It aids in regulating the estrus cycle, supports healthy embryo development, and contributes to foetal growth. Without adequate phosphorus, you might face fertility challenges among your dairy cows.
4. Milk Production
For lactating cows, phosphorus is a non-negotiable ingredient for high milk production. It’s a critical component of milk itself, and when phosphorus levels are insufficient, it can lead to reduced milk yield.
5. Immune Function
A well-functioning immune system is vital on any dairy farm. Phosphorus plays a role in maintaining the immune system’s strength, helping your cows resist health challenges.
6. pH Balance
Phosphorus also contributes to maintaining the acid-base balance (pH) in the rumen and digestive system. This balance is crucial for proper digestion and nutrient absorption in your cattle.
7. Overall Well-Being
Beyond these specific functions, phosphorus influences numerous physiological processes, including nerve function and cell membrane integrity. Ensuring an adequate supply of phosphorus is, therefore, essential for the overall health and well-being of your dairy cattle.
As you can see, phosphorus isn’t just a minor player in the dairy farm orchestra – it’s a star with multiple roles. To keep your herd healthy, productive, and thriving, providing an optimal phosphorus supply through a balanced diet is paramount.
When and how much phosphorus does a cow need?
According to GD research in 2020, the amount of phosphorus in milk can differ a lot from cow to cow and farm to farm. For optimal herd health, it is recommended that you determine the phosphorus in the cow’s diet based on the amount they excrete through milk.
Jan Dijkstra, associate professor of cattle nutrition at Wageningen University reports that the current standardisation has a wide safety margin. A diet with around 3.5 grams of phosphorus per kilogram of dry matter is enough for a lactating cow producing 10,000 kilograms of milk. In the past, the guidelines were too low, resulting in unconscious shortages. According to the associate professor, you can follow these (P) standards:
- Small calves 3.4 g/kg ds
- Older calves and heifers 2.3 g/kg ds
- Dry cows 2.0 g/kg ds
- Dairy animals need more: at 20 kg milk 2.5 g/kg ds, at 40 kg milk 3.3 g/kg ds and for animals with >40 kg milk the norm is 3.5 g/kg ds
Phosphorus is most important after calving
A cow’s demands for phosphorus are most critical at the start of lactation when transition and calving will have depleted the cows own reserves. Around calving, the cow’s body is already asking for extra energy and this demand will only increase in order to support milk production and facilitate post-calving recovery.
To ensure the health and productivity of their cows, dairy farmers need to pay special attention to phosphorus supplementation during the post-calving period.
The advice from the AHV Specialists
- The advice from the AHV Specialists is to administer the AHV Milk Start Tablet at the first signs of calving. Providing high quality calcium, phosphorus and magnesium along with Vitamin D3 to facilitate absorption, Milk Start ensures a highly bioavailable and sustained release of essential minerals. This formulation supports muscle contractions, milk production and promotes the metabolism.
- If you also have challenges with the afterbirth coming off, it’s often due to low calcium and phosphorus. This can happen when cows don’t eat enough during their dry period. To prevent this, right after calving, use the AHV Metri Tablet to help stimulate the release of the afterbirth release and cleanse the uterus.
- Then, give your cow a boost with the AHV StartLac Paste. It’s packed with highly bioavailable magnesium, calcium, phosphorus, and an energy kick, to help get your dairy cow up on her feet and eating after calving.
Implementing these solutions can significantly reduce the risk of challenges, and with extra milk delivered, you will already have earned back the investment. That’s not all, as the benefits extend to subsequent lactation, the healthy inception of your calves, improved fertility, and the avoidance of additional expenses associated with buying restorative products.
