Dr Randhawa informed that Dr Carvalho is one of the pioneer scientists associated with development of Assisted Reproductive Technologies like Fixed-Time Artificial Insemination (FTAI) and Embryo Transfer Technology (ETT) in buffalo. Dr Carvalho interacted with the faculty and PG students and delivered an expert lecture on usefulness of ETT for improving the buffalo germplasm. He also visited ETT Lab of GADVASU and exchanged his expertise through practical demonstration of embryo flushing in buffalo.
Dr Randhawa said that GADVASU has the expertise in cattle embryo transfer technology and has produced over 50 calves in the field. The university has already trained 46 field veterinary doctors in the field of ETT under the state sponsored ETT project. Dr Randhawa informed that varsity is also in the process to build facilities for embryo transfer in buffaloes and Dr(s) SPS Ghuman, VS Malik and Sumit Singhal are working in this area under the leadership of Dr PS Brar, Head, Veterinary Gynaecology & Obstetrics. The in vivo embryo production using superovulation protocols based on exogenous control of follicular wave emergence has been standardized and results are promising. The visit of Dr Carvalho to GADVASU provided an excellent opportunity to gain experience as a step toward fulfilling the mutual goals of India and Brazil for increasing the reproductive efficiency of buffalo.
