What Happened
- The ICAR–Indian Veterinary Research Institute (IVRI), Izatnagar, Bareilly, Uttar Pradesh, has achieved a landmark breakthrough by successfully producing five healthy Sahiwal calves using the OPU–IVF–ET (Ovum Pick-Up, In Vitro Fertilisation, Embryo Transfer) technology — the first such success at the institute.
- All five calves were born within five days starting February 28, 2026, demonstrating high efficiency of the technique.
- The donor cow was a high-yielding Sahiwal producing over 12 litres of milk per day; semen from a proven bull with a maternal lactation yield of approximately 3,320 kg was used, ensuring strong genetic merit in the offspring.
- This technique allows scientists to produce 20–40 calves per year from a single elite donor cow, compared to only one calf per year through natural reproduction.
- The breakthrough supports India's efforts under the Rashtriya Gokul Mission to conserve and multiply superior indigenous bovine germplasm.

OPU-IVF-ET Technology: How It Works
OPU-IVF-ET is a three-stage advanced assisted reproductive technology used in livestock. It enables rapid multiplication of genetically superior animals by combining ultrasound-guided egg collection, laboratory fertilisation, and embryo transfer into surrogate mothers.
- OPU (Ovum Pick-Up): Mature oocytes (eggs) are aspirated from the ovaries of a live, high-value donor cow using an ultrasound-guided needle — without surgery. This can be done repeatedly (typically every 1–2 weeks) from the same donor.
- IVF (In Vitro Fertilisation): The collected oocytes are fertilised in a laboratory dish using semen from a genetically superior bull, and the resulting embryos are cultured for several days.
- ET (Embryo Transfer): Viable embryos are implanted into surrogate cows of lower genetic value, which carry the pregnancies to term.
- The entire process can yield 20–40 calves per year from a single donor cow vs. one calf/year naturally.
- The technique is being scaled under Government of India's Rashtriya Gokul Mission, which is funding ~30 OPU-IVF facilities across the country.
- Ultrasound-guided OPU is non-invasive and safer than older surgical embryo recovery methods.
Connection to this news: IVRI's success is the first institutionally validated OPU-IVF-ET result for the Sahiwal breed, demonstrating that this technology can now be deployed to multiply India's most prized indigenous cattle at scale.
Sahiwal Cattle: India's Premier Indigenous Dairy Breed
The Sahiwal is one of India's most valued indigenous zebu (Bos indicus) cattle breeds, recognised for combining reasonable milk yields with exceptional adaptability to tropical conditions — traits that make it critical for sustainable Indian dairy farming.
- Origin: Named after Sahiwal district of Pakistan's Punjab province; distributed across Punjab, Haryana, Rajasthan, and Uttar Pradesh on the Indian side.
- Milk yield: Average lactation yield of ~2,325 kg; recorded up to 6,000 litres under optimal farm management.
- Adaptive traits: Heat-tolerant, tick-resistant, and disease-resilient — key advantages over high-yielding exotic breeds like Holstein-Friesian in India's hot and humid climate.
- Multi-purpose: Reared for milk, draught work, and meat — making it economically vital for small and marginal farmers.
- Conservation concern: Indiscriminate crossbreeding with exotic breeds has drastically reduced pure Sahiwal numbers; only a few hundred animals remain under field conditions along the Indo-Pakistan border.
- Registered breeds: India has 41 registered indigenous cow breeds and 13 buffalo breeds; Sahiwal is among the most prominent.
Connection to this news: IVRI's IVF calves are all Sahiwal — the technology directly addresses the conservation crisis facing this breed by enabling multiplication of genetically pure, high-yielding animals without relying on scarce natural breeding populations.
Rashtriya Gokul Mission: Policy Framework for Indigenous Breed Conservation
The Rashtriya Gokul Mission (RGM) is a central government flagship scheme under the Department of Animal Husbandry and Dairying (DAHD) aimed at conserving and developing indigenous bovine breeds and increasing milk production through scientific breeding.
- Launched: December 2014; revamped and extended for 2021–2026 with a ₹2,400 crore allocation.
- Key components:
- Gokul Grams: Integrated cattle development centres for indigenous breed propagation.
- National Kamdhenu Breeding Centres: Centres of excellence for elite breed development.
- National Bovine Genomic Centre for Indigenous Breeds: Genomic selection to identify superior animals.
- Establishment and strengthening of ET/IVF centres — directly enabling IVRI-type breakthroughs.
- Target: Setting up ~30 OPU-IVF facilities across India to take technology to farmers' doorsteps.
- Broader goal: Increase milk production, reduce import dependence for exotic breeds, and conserve India's unique genetic heritage in livestock.
- India is the world's largest milk producer (over 230 million tonnes per year), yet per-animal productivity remains low compared to global averages — RGM directly targets this productivity gap.
Connection to this news: IVRI's breakthrough is a direct output of the RGM's investment in IVF infrastructure, validating the mission's strategy of using biotechnology to scale up indigenous breed numbers rapidly.
India's Dairy Sector: Economic and Food Security Dimensions
India is the world's largest producer of milk and the dairy sector is the single largest agricultural commodity, contributing about 5% of GDP. Yet the sector faces a structural challenge: average milk yield per animal is significantly below global standards, largely because of the dilution of high-yielding indigenous breeds through unscientific crossbreeding.
- India produces over 230 million tonnes of milk annually (as of 2023–24), a fourfold increase since Operation Flood (1970s–1990s).
- Average milk yield of Indian cows: ~1,777 kg/lactation vs. ~10,000 kg/lactation for Holstein-Friesian (exotic).
- Over 80% of milk in India is produced by small and marginal farmers who keep 1–5 animals — making breed improvement directly relevant to rural income.
- Exotic breed crossbreeds have higher yields but lower disease resistance and heat tolerance, increasing input costs (veterinary, housing, feed).
- Indigenous improved breeds like Sahiwal offer a middle path: moderate-to-good yields with low input costs — ideal for smallholder farming systems.
- The National Action Plan for Dairy Development (2022–2027) targets 330 million tonnes of milk production by 2033–34.
Connection to this news: Multiplying genetically elite Sahiwal animals through IVF is a key lever to raise smallholder productivity without the risks associated with exotic crossbreeding — directly contributing to India's dairy and food security goals.
