Embryonic Losses in Dairy Cows: Early & Late Embryonic Death

Embryonic mortality is a major hidden cause of low fertility in modern dairy herds.

Early Embryonic Death (EED)
Losses up to day 24–30 post-AI, often expressed as repeat breeding.

Late Embryonic Death (LED)
Losses between day 30–42, usually after a confirmed pregnancy.

Common contributing factors include:
▪️ Low progesterone and weak luteal function
▪️ Negative energy balance and nutritional imbalance
▪️ Subclinical uterine infections
▪️ Heat stress
▪️ AI timing and semen handling errors

From a practical dairy-farm perspective, improving embryo survival requires a system-level approach

✅ Transition cow & heifer nutrition
✅ Uterine health and calving hygiene
✅ Accurate breeding and pregnancy monitoring
✅ Heat stress management
✅ Strategic hormonal support in repeat breeders

Fertility success is not about one treatment — it’s about consistent management and attention to detail.

Starting of Breeding Season 2025–2026: Time to Prepare Your Herd for Success

As we step into the 2025–2026 breeding season, it’s the perfect time to prepare your cows and heifers for strong fertility, better conception rates, and healthy pregnancies .Success in breeding starts long before insemination .it begins with good nutrition, health, and management.

1️⃣ Review Animal Health

Before breeding begins:

* Perform body condition scoring (BCS) aim for 2.75–3.25
* Deworm and vaccinate according to your herd health plan.
* Check for any reproductive disorders (repeat breeders, cysts, uterine infections).
* Conduct a pregnancy diagnosis to separate pregnant from open cows early.

➡️ Healthy, disease-free animals are always more fertile.

2️⃣ Review Nutrition Before Breeding

Nutrition plays a major role in fertility.

* Ensure animals are on a balanced ration rich in energy, protein, and minerals.
* Include green fodder and quality silage for fresh energy.
* Provide breeding mineral mixtures containing calcium, phosphorus, copper, selenium, and vitamin E.
* Avoid over-conditioned (fat) or underfed cows both reduce conception rates.

➡️ A well-fed cow shows stronger heat signs and higher conception success.

3️⃣ Water and Comfort

* Always provide clean, cool water— dehydration affects fertility.
* Maintain comfortable housing with proper ventilation and dry bedding.
* Reduce stress — high temperature and overcrowding delay heat cycles.

4️⃣ Reproductive Management

* Record and observe heat signs on daily.
* Use AI (artificial insemination) at the correct time 12–18 hours after standing heat.
* If possible, check semen quality and storage conditions.
* For better results, involve an experienced AI technician or veterinarian.

5️⃣ Post-Breeding Care

* Avoid stress and sudden feed changes after insemination.
* Confirm pregnancy at 30-45days.
* Continue providing balanced nutrition and minerals for embryo survival.

🌿 Final Message

Good fertility is not luck — it’s the result of preparation.
Healthy animals, balanced diets, and timely breeding decisions will ensure the 2025–2026 breeding season brings more conceptions, more calves, and better farm profits.

Prepare early — breed smart — succeed together!
