IVRI Breakthrough Boosts Sahiwal Genetic Gains
The ICAR–Indian Veterinary Research Institute (IVRI), Izatnagar, Bareilly, has achieved a major breakthrough by successfully producing indigenous Sahiwal calves using advanced Assisted Reproductive Technologies (ART), marking the institute’s first-ever success with ultrasound-guided ovum pick-up, in vitro fertilisation and embryo transfer (OPU–IVF–ET). This milestone opens new avenues for rapid genetic improvement of India’s indigenous dairy breeds and strengthens conservation efforts for valuable germplasm.
The achievement stems from a focused programme initiated during 2022–23 to enhance the genetic potential of key dairy breeds including Sahiwal, Tharparkar and Murrah buffalo, with scientists standardising OPU–IVF–ET protocols under both farm and field conditions. The effort culminated in the birth of five healthy Sahiwal calves within just five days starting February 28, 2026. These calves were produced from superior germplasm, with oocytes sourced from a high-yielding Sahiwal cow producing over 12 litres of milk per day and fertilised using semen from a proven bull with an approximate maternal lactation yield of 3,320 kg, ensuring strong genetic merit.
Technically, the programme demonstrated strong efficiency, with oocyte recovery achieved even under non-stimulated conditions, averaging around 14.5 in Tharparkar, 13.14 in Sahiwal and 4.5–5.5 in Murrah buffalo. Embryo development was equally robust, with blastocyst production rates exceeding 47% in cattle and over 42% in buffalo—levels comparable to leading global laboratories. The institute now plans to scale up the use of OPU–IVF–ET technology to accelerate the production of elite indigenous cattle and buffalo, while also promoting training programmes to build skilled manpower, support start-ups and drive innovation across the livestock sector.
