Services
SEQ Genetics provides specialised OPU and IVF services designed to help cattle producers fast‑track genetic progress and get more high‑value calves on the ground. Using modern reproductive technology, we turn elite females into multiple pregnancies, giving producers more options, more embryos, and more return from their top genetics.
Ideal Donor
​
-
Body Condition Score 2.5–3.5 (on a 1–5 scale).
-
On a rising plane of nutrition — not losing weight or overly fat.
-
Cycling normally and at least 4 weeks post‑calving.
-
Suitable for OPU up to around 100 days pregnant.
-
Not too young (pre‑pubertal) or too old.
-
Good antral follicle count (≥ 15 follicles), assessed by ultrasound.
-
Bos indicus–influenced breeds often produce more oocytes and embryos.
Preparation of your Donors
Good management in the weeks leading up to OPU has a major impact on results.
Nutrition
For at least 6 weeks before OPU:
-
Keep donors gaining weight.
-
Avoid clover and lucerne pastures (phytoestrogens and excess protein can affect ovaries).
-
If supplementing, use good‑quality cereal hay.
-
Avoid high‑protein grain mixes.
-
Ensure trace minerals are adequate — commonly supplemented nutrients include:
-
Vitamins A, D, E
-
Multimin
-
Phosphorus
-
Selenium
-
Vitamin B12
-
Heifer Donors
Heifers can fast‑track genetic gain, but:
-
They may produce fewer oocytes and embryos than mature cows.
-
Heifers should be around 350 kg for safe handling and good ovarian development.
Vaccinations
-
Follow recommended vaccination programs
-
Give all vaccinations and treatments at least 4 weeks before OPU.
-
Donors should be healthy, calm, and free from recent stress.
Why Producers Choose SEQ Genetics IVF.
• Higher embryo output from elite donors
OPU–IVF allows you to collect oocytes every 7–14 days, producing more embryos in less time compared to conventional ET.
• Works on donors that won’t respond to flushing
IVF is ideal for donors that are pregnant, non‑cycling, or poor responders to super‑ovulation.
• Accelerate genetic gain
Multiply your best cows and heifers quickly, producing more sale‑quality progeny and high‑value replacements.
• Flexible, practical programs
Tailored breeding plans to suit stud and commercial operations across QLD and Northern NSW.
• Local service backed by specialist expertise
Reliable scheduling, clear communication, and a focus on practical outcomes for real producers.
Producers across Queensland and Northern NSW can easily book OPU spots, discuss donor suitability, or plan an IVF program with SEQ Genetics IVF. Whether you’re chasing more embryos from elite cows, looking for advice on donor preparation, or wanting to fast‑track genetic gain, we’re here to help.
