NDDB’s Indigenous GauSort Technology Drives Rise in Female Calf Births Across India

08 May 2026, New Delhi: A significant rise in the birth of female calves is being reported across India through the adoption of GauSort, an indigenous gender-sorting semen technology that is bringing a major transformation to the country’s dairy sector. Launched by Prime Minister Mr. Narendra Modi in October 2024, the technology is rapidly gaining ground in bovine breeding programmes nationwide.

Developed by the National Dairy Development Board (NDDB) in collaboration with the Department of Animal Husbandry and Dairying, Government of India, the innovation is being implemented by NDDB Dairy Services under the Rashtriya Gokul Mission. The initiative is aimed at producing superior quality livestock, improving milk productivity and ensuring long-term income stability for dairy farmers.

The use of GauSort technology has now expanded across multiple states, enabling farmers to access more precise and efficient breeding services. The technology is helping improve livestock quality while making dairy farming more organised, dependable and productive.

Under Project Gir Varanasi, the technology has delivered highly encouraging results, with nearly 91% female calf births recorded so far. The outcome highlights the effectiveness of the indigenous innovation. As these calves mature, they are expected to significantly strengthen dairy-based livelihoods and create additional income opportunities for farmers.

Speaking on the development, Dr. Meenesh Shah, Chairman, NDDB, said, “Gausort is not just a technology, it is a powerful tool shaping the future of India’s dairy sector. This cost effective innovation is enabling the birth of higher proportion of female calves, leading to improved productivity and stable income. Under the Rashtriya Gokul Mission, its expansion is laying the foundation for a new dairy revolution in the country. The results from Project Gir Varanasi clearly demonstrate that when modern technology reaches rural India effectively, it not only enhances production but also brings lasting positive change in farmers’ lives.”

The impact of GauSort technology is also becoming increasingly visible in districts of western Uttar Pradesh, including Meerut, Muzaffarnagar, Saharanpur, Bijnor, Bulandshahr, Hapur and Shamli. In these districts, around 91% of calves born through the technology are female, further reinforcing the reliability and effectiveness of the innovation. The technology is also contributing to stronger rural economies by improving milk production and enhancing farmers’ incomes.

Farmers using GauSort technology are already witnessing visible benefits on the ground. Rajveer, a dairy farmer from Varanasi, shared his experience, saying, “With the help of GauSort technology, I have witnessed the birth of many female calves. Earlier we were unsure about the gender of the calf but through this technology we are confident that the chances of female calves are much higher. This will increase milk producing animals and improve our income. Dairying will now become more profitable due to this technology.”
