Scientists at the National Institute of Animal Nutrition and Physiology (NIANP) in Bengaluru have developed CRYODIL, a ready‑to‑use, egg‑yolk‑free semen extender designed specifically for buffaloes. The technology promises to improve the success rate of artificial insemination and was highlighted during recent updates on livestock innovation.
Background
Semen extenders are nutrient solutions that protect sperm during chilling, freezing and thawing, thereby enabling artificial insemination across long distances and time intervals. Traditional extenders use egg yolk as a source of proteins and lipids; however, egg yolk carries a risk of microbial contamination and batch‑to‑batch variability. Developing a plant‑based or synthetic alternative can improve hygiene, extend shelf‑life and reduce costs.
Features of CRYODIL
- Egg‑yolk‑free formulation: By replacing egg yolk with safer ingredients, CRYODIL minimises the risk of bacterial contamination and allergic reactions.
- Ready to use: The extender comes in a pre‑measured liquid form that does not require mixing or warming. This reduces preparation time and errors, especially in field conditions.
- Long shelf‑life: Laboratory testing indicates a shelf‑life of at least 18 months under refrigeration, making it practical for semen banks and breeding centres.
- Improved motility: Post‑thaw evaluations show higher progressive motility of buffalo sperm preserved in CRYODIL compared with traditional egg‑yolk‑based extenders, increasing the likelihood of successful fertilisation.
- Cost effectiveness: Ingredients are sourced locally and can be produced at lower cost than imported egg‑yolk‑based extenders.
About ICAR and NIANP
The Indian Council of Agricultural Research (ICAR), established in 1929 under the Department of Agricultural Research and Education, is the apex body for coordinating agricultural research and education in India. ICAR oversees more than 100 research institutes and 70 agricultural universities. NIANP, one of its institutes located in Bengaluru, conducts research on animal nutrition, physiology and reproductive technologies.
Significance
- Improved semen preservation will help buffalo farmers increase conception rates, thereby enhancing milk and meat production.
- A hygienic, long‑lasting extender reduces waste and logistics costs for artificial insemination centres.
- Local development of such technologies supports the Make in India initiative and reduces dependence on imported veterinary supplies.
Conclusion
CRYODIL illustrates how innovation in animal science can deliver practical solutions for livestock producers. As the technology is adopted by semen banks and breeding services, it may contribute to increased productivity and income for buffalo farmers across India.
