Energy is essential for good fertility

Energy is the fuel to a cow’s body. If a cow is well supplied with energy, it will have a positive contribution to milk production, fertility, immunity and calving, among other things. Unfortunately, there are times when energy supply is compromised, which greatly affects her fertility. To overcome these tough periods, AHV has developed the Energy & Metabolism Program. We put the cow in her power with our Booster products so she is well prepared to fight and thrive during difficult periods.

Negative Energy Balance (NEB) after calving is inevitable

Optimal energy balance is important for cow health. Unfortunately, it is inevitable that dairy cows go into an energy dip after calving. At that time, they do not take in enough food to provide the energy needed for milk synthesis. Every cow experiences this so-called Negative Energy Balance (NEB) at the beginning of lactation.

Two weeks before calving, this problem has already started. The unborn calf grows rapidly in the last two weeks of dry-off, increasing the size of the uterus and compromising the rumen. The calf’s rapid growth uses a lot of the cow’s energy. To make matters worse, the cow takes in less dry matter during this period. Also, milk production will already start during this period, demanding even more energy. A cow then starts drawing on her fat reserves, possibly resulting in fatty liver.

How can a NEB cause fatty liver?

A cow that is in too deep of a negative energy balance mobilizes and uses her own body fat as a source of energy, trying to restore the balance. When a cow mobilizes a lot of body fat, the liver cannot process it properly. This results in the liver clogging up, so to speak. In addition, metabolic challenges may also occur. The liver will then produce less glucose, forcing the cow even further into a negative energy balance, as well as decreasing her production and immune system. A fatty liver will also not be able to filter the blood as well which is very detrimental to good immunity.

What are the consequences of fatty liver?

Failure to address fatty liver challenges can have far-reaching consequences for the fertility of your cows. In fact, fatty liver is a major cause of fertility challenges. It can also lead to other things like:

1. Poor uterine recovery after calving that leaves more cows with a retained placenta
2. These cows often have no activity on the ovaries and show no heat
3. A negative impact on conception rates resulting in fewer cows pregnant

Too deep of a negative energy balance can be tackled with AHV solutions. It is important to take timely action on reduced energy levels so that the cow can return to optimal performance. With AHV solutions, you put the cow in her power, so she herself is well prepared to compete during a tough period.

When to apply AHV Booster for fertility?

Animals showing poor heats are not getting enough energy from the ration. The AHV Booster Bolus (14-7 days before calving) stimulates the cow to use energy from the ration more efficiently, minimizes the detrimental effects of negative energy balance, and promotes rumen functionality. This increases the chances of successful ovulation many times over. The fertilization rate increases, and overall health improves.

When there is a need for lots of quick energy, drenching with the Booster Powder is the best solution given in combination with the Booster Bolus. The rumen should be filled as soon as possible, after the birth of the calf. Thus, the rumen fills the space where the calf used to be. This avoids a displaced abomasum. By drenching with AHV Booster Powder, you not only fill the empty space and provide hydration, but also ensure that your cow starts drinking and eating again. This contributes to the elimination of undesirable substances.
