Recently, the Indian Council of Agricultural Research–Indian Veterinary Research Institute successfully produced indigenous Sahiwal cattle calves using advanced reproductive technologies such as ultrasound-guided ovum pick-up, in vitro fertilization, and embryo transfer (OPU–IVF–ET). This marks a significant step in scientific breeding and conservation of indigenous cattle breeds in India.
The use of modern biotechnology helps improve genetic quality and accelerate breeding of superior indigenous cattle.
About Sahiwal Cattle
Sahiwal cattle are regarded as one of the best indigenous milch (milk-producing) breeds in India. The breed derives its name from the Sahiwal region in present-day Pakistan.
They are also known by various local names such as Lambi Bar, Lola, Montgomery, Multani, and Teli, reflecting their wide historical presence.
In terms of appearance, Sahiwal cows are typically brownish-red in colour, with shades ranging from reddish-brown to greyish-red. Bulls usually have darker extremities, and occasionally, white patches may be seen.
The breed is known for a high average milk yield of about 2325 kg per lactation, with a range between 1600 and 2750 kg.
Sahiwal cattle combine high milk productivity with strong adaptability, making them highly valuable.
Key Characteristics of Sahiwal Cattle
Sahiwal cattle possess several unique features that make them ideal for tropical conditions. They are highly heat tolerant, which allows them to thrive in hot climates. Additionally, they show strong resistance to ticks and parasites, both internal and external.
These cattle are also known for their robust health and adaptability, which reduces maintenance costs for farmers. Due to these advantages, Sahiwal cattle have been exported to several countries in Asia, Africa, and the Caribbean.
Their disease resistance and climate adaptability make them crucial for sustainable dairy farming.
OPU–IVF Technology Explained
Ovum Pick-Up–In Vitro Fertilization (OPU–IVF) is an advanced reproductive biotechnology used to enhance animal breeding.
Ovum Pick-Up (OPU) involves collecting oocytes (eggs) directly from the ovaries of a live animal using a needle guided by ultrasonography. This process allows scientists to obtain eggs from animals with desirable genetic traits.
These oocytes are then matured and fertilized in a laboratory through in vitro fertilization (IVF). The resulting embryos are cultured and later transferred into surrogate animals to produce offspring.
An important advantage of this technique is that it can be performed even on pregnant animals (within early gestation), thereby significantly reducing the time between generations.
OPU–IVF technology enables rapid multiplication of superior genetic traits and faster breed improvement.
Significance of the Development
This achievement is highly significant for India’s livestock sector. It supports the conservation and improvement of indigenous breeds, which are often better adapted to local conditions than exotic breeds.
It also strengthens dairy productivity, enhances farmers’ incomes, and reduces dependence on imported genetic material. Moreover, such technologies contribute to sustainable and climate-resilient agriculture.
Scientific breeding techniques like OPU–IVF are key to boosting dairy efficiency while preserving indigenous genetic resources.
Conclusion
The successful use of OPU–IVF technology in Sahiwal cattle represents a major advancement in India’s animal husbandry sector. By combining traditional breed strengths with modern biotechnology, India can ensure both higher productivity and long-term sustainability in dairy farming
