#1
OPU-IVF stands for Ovum Pick-Up combined with In-Vitro Fertilization, an advanced assisted reproductive technology for livestock multiplication.
#2
Indigenous Indian cattle belong to the species Bos indicus (zebu cattle), characterized by a prominent shoulder hump, dewlap, and natural heat tolerance.
#3
Prominent indigenous dairy breeds conserved through OPU-IVF include Gir (Gujarat), Sahiwal (Punjab/Haryana), Red Sindhi, Tharparkar (Rajasthan), and Rathi.
#4
Indigenous cattle predominantly carry the A2 beta-casein gene, producing milk favored for digestibility compared to the A1 variant common in exotic taurine breeds.
#5
Under natural mating or artificial insemination (AI), a healthy dairy cow typically produces only 6 to 8 calves over her entire biological lifetime.
#6
Using OPU-IVF, an elite donor cow can produce 30 to 50 viable calves annually by transferring laboratory-produced embryos into surrogate recipient cows.
#7
Ovum Pick-Up (OPU) involves transvaginal ultrasound-guided aspiration of oocytes from the ovaries of live donor cows without major surgical intervention.
#8
Unlike Multiple Ovulation Embryo Transfer (MOET), OPU does not depend on heavy hormonal superovulation protocols using gonadotropins like FSH.
#9
Because OPU is minimally invasive, oocytes can be harvested from an elite donor cow every week or fortnight, even during the first trimester of pregnancy.
#10
After aspiration, harvested oocytes undergo In-Vitro Maturation (IVM) in incubators for 24 hours under physiological carbon dioxide and temperature controls.
#11
In-Vitro Fertilization (IVF) combines matured oocytes with capacitated spermatozoa from elite, progeny-tested bulls to form single-cell zygotes.
#12
Use of sex-sorted semen in bovine IVF allows laboratories to ensure that over 90% of resulting blastocysts are female, maximizing dairy herd growth.
#13
Embryos are cultured in-vitro (IVC) for 7 days until reaching the blastocyst stage before non-surgical transfer into synchronized recipient cattle.
#14
Embryos can be cryopreserved indefinitely in liquid nitrogen at -196°C, creating a permanent ex-situ genetic vault for endangered cattle breeds.
#15
The Rashtriya Gokul Mission (RGM), launched in December 2014 by the Ministry of Fisheries, Animal Husbandry and Dairying, funds the nationwide expansion of bovine IVF.
#16
RGM established over 30 state-of-the-art bovine IVF laboratories across India in partnership with the National Dairy Development Board (NDDB).
#17
The Central Government provides financial subsidies to dairy farmers under RGM for the transfer of verified indigenous breed IVF blastocysts.
#18
OPU-IVF allows the rescue of endangered localized breeds with dwindling populations, such as Punganur (dwarf breed of Andhra Pradesh) and Vechur (Kerala).
#19
Recipient surrogate cows can be non-descript or low-yielding indigenous cattle, which successfully carry high-pedigree elite blastocysts to term.
#20
The technology ensures strict biosecurity, preventing the transmission of reproductive pathogens like Brucellosis and Bovine Viral Diarrhea.
Subject Specialist Commentary
Analytical perspective & practical exam advice from the Master10 academic board
OPU-IVF stands for Ovum Pick-Up combined with In-Vitro Fertilization, an advanced reproductive method helping multiply India's indigenous cattle breeds like Gir, Sahiwal, and Tharparkar. Under natural mating, a prize cow yields only six to eight calves in her lifetime. With OPU-IVF, veterinarians collect eggs non-surgically using ultrasound guidance, fertilize them in a laboratory, and implant embryos into ordinary surrogate cows, enabling a single elite donor to produce up to fifty high-yielding calves annually.
For UPSC prelims and State PSC agriculture questions, contrast OPU-IVF with traditional Multiple Ovulation Embryo Transfer (MOET). Remember that OPU does not require heavy hormone injections and can be repeated frequently. A recurring exam trap tests government initiatives; connect this technology directly to the Rashtriya Gokul Mission launched in 2014. Also note the use of sex-sorted semen, which ensures that over ninety percent of newborn calves are female to support dairy productivity.
