Achieving Better Uterine Health and Increased Milk Output with AHV

When cows face uterine issues, their activity levels drop, leading to reduced dry matter intake—and that can set off a chain reaction. Lower feed intake means less energy, which directly impacts fertility factors like insemination success, heat detection, and the time between calvings. It doesn’t stop there—milk production, overall health, and added costs all take a hit.

The good news? The AHV Metri Tablet, paired with the AHV Aspi Tablet, helps improve uterine health, encourages placental release, and improves animal welfare and recovery. Recent research from AHV’s Technical Specialists highlights the positive impact of these products, helping your herd stay healthy and productive.

In a trial on a US dairy farm, in which 367 dairy cows participated, the results of the AHV Metri and Aspi Tablet were examined by measuring increased milk production, decrease in uterine health issues (concerning uterine hygiene and placental release), and improved fertility through application of the two AHV products directly after calving.

All cows were split into two groups; a AHV group, consisting of 158 cows and a control group consisting of 209 cows. The two groups were split based on ancestry, depending on whether the cow was sired by a Holstein or non-Holstein and whether the animal was pregnant through sexed Holstein semen (HO) or by semen from beef cattle (XB).

US Dairy Trial Results on Uterine Health

The main observations during this trial showed that for both the HO calves and the XB calves there was a reduction in the number of strong uterine issues in the AHV group. As you can see in figure 1. Of the control group, which was not given AHV products, 5.19% of dairy cows in the second lactation and 5.77% of cows in the third or higher lactation showed strong uterine health issues. On the other hand, of the cows that were given AHV’s products, only respectively 3,23% and 2,41% showed strong uterine health issues.

For the XB calves, of the cows in the control group 14.29% of dairy cows in the second lactation and 21.05% of cows in the third or higher lactation showed strong uterine health issues. The cows of the AHV group showed a strong decrease in the percentage of cows suffering from uterine health issues, namely 6.06% and 8.70% respectively.

Additionally, a slight increase in daily milk yield was found, as the yield went up with 1.0 kilogram in the AHV groups.

Optimal support post calving with StartLac, Aspi and Metri

The aforementioned improvement in uterine health is not only important for the short term, but also for the results throughout the lactation. For optimal results, our StartLac Tablet (or StartLac Paste) should also be put into the mix. This product reduces the risk of milk fever and subclinical hypocalcemia after calving, while also ensuring sufficient nutrient intake. Therefore, it is recommended to provide AHV Metri Tablet, StartLac and Aspi Tablet to all your dairy cows immediately after calving.
