Embryo transfer technology (ETT) has revolutionized the breeding strategies in bovines as a tool to optimise the genetic improvement in cattle. What are benefits of using ETT?

1.It leads to a decrease in the number of offspring resulting in improved feed and nutrition to the existing offspring.

2.The offsprings born using this method will be free from diseases.

3.It is a potential tool in livestock transgenesis and diversity conservation.

Explanation:

ETT is a potential tool in livestock genetic engineering. It consists of a series of integrated sequential steps from donor selection, donor treatment for superovulation, insemination of the superovulated donor, embryo recovery, etc.
Statement 1 and 2: A farmer can get a 5-6 fold increase in the number of offspring. The calves so born will be of high genetic merit.
In a bid to conserve indigenous breed of cattle, the government has undertaken a Mass Embryo Transfer programme in Indigenous Breeds under the scheme, National Mission on Bovine Productivity.
Statement 3: Transgenesis is the process of introducing an exogenous gene—called a transgene—into a living organism so that the organism will exhibit a new property and transmit that property to its offspring.
