A day after Union Minister Giriraj Singh sparked controversy over his 'cow birth factories' statement, he clarified on Monday that the word 'factory' was used to explain the breeding technique to the cow keepers.

"With help of the in-vitro fertilization (IVF) and Embryo Transplant, the unproductive livestock in the country will be utilized as surrogate mothers. The word 'factory' was used to explain these techniques to friends who pet cows and not to open political factories for people," Singh said in a tweet.
