It is well documented that early embryo loss is one of the most significant factors in pregnancy rates. An early loss of pregnancy (loss of embryo before day 42) is mostly attributed to management related conditions and not infections. Cows that lose > 1 body condition score in the space of the first 30 days of lactation, have a 2.4 times greater risk of embryo loss.

To avoid embryo loss, it is important that the embryo develops sufficiently in the first period after impregnation. A well-developed embryo secretes sufficient amounts of a protein that acts locally in the uterus and prevents the secretion of the reproduction hormones that trigger a new cycle.

Over the course of the past few decades, the proportion of cows that go into standing heat has fallen from 80 to 50 percent, and the duration of standing heat has dropped from 15 to 5 hours. This presents a challenge when determining the right time for insemination in relation to ovulation. In terms of biology, it is natural that some cows should be inseminated again, which is why it is important to detect when the next estrus occurs.

There can be several reasons why cows should be inseminated again:

🔶 Because insemination failed and the cow is not pregnant
🔶 Loss of embryos after insemination
🔶 Presence of follicular or luteal cysts.

Feed efficiency now counts more in the total merit index 🧬💰

After the May 2026 proof run, Saved Feed has gained significantly more weight in the Nordic Total Merit (NTM) for Holstein, RDC and Jersey. This means differences in Saved Feed now have a clearer impact on a bull’s total merit — making feed efficiency a more influential trait in breeding decisions.

The weight assigned to Saved Feed in NTM has increased substantially: for Holstein from 0.18 to 0.35, for RDC from 0.13 to 0.35, and for Jersey from 0.18 to 0.38 — representing roughly a doubling for Holstein and Jersey and more than a threefold increase for RDC.

The change reflects higher feed costs, improved data and genetic models, and increasing climate requirements. Selecting bulls with strong Saved Feed performance now delivers greater impact on profitability, resource use and long term herd efficiency.
