Germplasm station of RCDF ltd. is situated at –

A germplasm station is a specialised livestock-breeding facility that conserves and multiplies superior genetic material — such as elite bull semen — to improve dairy-cattle productivity. In Rajasthan, such stations are set up and operated under the Rajasthan Co-operative Dairy Federation (RCDF) network to support the state's milk-producer cooperatives.

RCDF Ltd.'s Germplasm Station is located at Narwa Khichiyan in Jodhpur district, from where it supplies quality bull semen to milk-producer cooperative societies across western Rajasthan.

• Jobner (Jaipur) is known for the state's agricultural research and education institutions, not for RCDF's germplasm/breeding infrastructure.

• Nadol (Pali) hosts other regional agricultural and heritage establishments, not RCDF's germplasm station.

• Barsingsar (Bikaner) is known chiefly for its lignite deposits and thermal power generation, unrelated to dairy-breeding infrastructure.

Hence, among the given places, Narwa Khichiyan (Jodhpur) is the site of RCDF Ltd.'s Germplasm Station.
