Major Research Accomplishments
 

The technique of transvaginal ultrasonography for Ovum Pick Up was standardised and the feasibility of obtaining oocytes from cattle and buffaloes was demonstrated. Repeated collection of oocytes through OPU from cattle and buffalo showed no adverse effects on follicular growth and development.

Standardised the non-invasive technique of ultrasonography for monitoring follicular changes, pregnancy diagnosis, detection of ovulation and corpora lutea in normal cycling and superovulated cattle and buffaloes. Applying this technique the reasons for poor superovulatory responses, like inability of follicles to ovulate, shift, recruitment and passage of follicles from small to large size, predominance of two wave follicular activity, effect of presence of dominant follicle in cattle and buffalo, follicular population and dynamics in bovines were studied.

Standardised the protocols for superovulation both for indigenous and crossbred cattle  and many calves were produced from elite donors. A record number of ten calves were produced in one year using ET technology and the same has been recorded in Limica Book of Records.

Modified and simple technique of in vitro fertilization developed and results optimized in buffaloes using slaughterhouse ovaries. The optimization procedure involved series of experiments to test various types of sera, hormones, growth factors, different time intervals, culture and capacitation conditions for spermatozoa etc. Six calves were produced to reveal the feasibility of the technology.

Various steps involved in micromanipulation and cloning of embryos were standardised. Worlds first cloned calf was produced on 6th February, 2009 using hand guided cloning technique. Using the same technique, a calf GARIMA was produced on 6th June, 2009.
  
Putative buffalo embryonic stem cells were produced by culture of inner cell mass cells obtained from in vitro produced buffalo blastocysts and when subjected to induced differentiation by culture in the presence of all-trans retinoic acid, they differentiated to neuron-like cells, which were found to express NF-68 gene, a specific marker for neuronal cells confirming that the cells produced were indeed neurons.  

 A simple and rapid method was standardized for the cryopreservation of buffalo oocytes by vitrification. It was demonstrated that it was possible to cryopreserve buffalo oocytes by vitrification. However, protocols effective for the vitrification of cumulus-oocyte-complexes were not suitable for denuded oocytes

Animal Birth Control vaccine (TALSUR), which was developed at National Institute of Immunology, New Delhi was first time tested in buffalo and cattle bulls and bucks at NDRI and protocol of injection and testing method was developed. The technology developed was also tested in village Bhusli, near Karnal where the buffalo bulls were sterilised and this news was reported in NATURE.
