However, monks at Bhaktivedanta Manor in Hertfordshire are devastated over the cow's death and have accused the government of underhand tactics in the animal's slaughter.
Cows are sacred in the Hindu faith and the temple's president compared the killing of the cow to the pain he would feel if his mother was killed.
Gauri Das said: ''You can expect protests and lobbying, we will do whatever it takes to be heard. We are all in shock at the moment, we are all too shocked to even be angry.''
The outrage over Gangotri's death follows that caused by the government-ordered slaughter of Shambo, a sacred Hindu bull who was killed in Wales after angry protests from monks.
The government's swift action in this case may have been to avoid any angry stand-off with the Hertfordshire-based monks.
The plight of Gangotri yesterday sparked fierce debate in the House of Commons. Barry Gardiner, the Labour MP for Brent North, said: ''At 9am this morning an outrage was perpetrated against the Hindu community in this country.
''An RSPCA vet accompanied by three police officers went unannounced to Bhaktivedanta Manor and put down a cow, a sacred cow, which had been nursed by the herdsman at the manor for 14 months.
''This cow I must stress was not contagious in any way, was not diseased, she had a muscle wasting problem and was nursed for bed sores alone.''
He added: ''This is something which has caused great concern amongst the community - and we have laws against blasphemy in this country.''
Harriet Harman, the leader of the Commons, said that she understood the ''huge strength of feeling and concern'' and said that Hilary Benn, the Environment Secretary, would write to Mr Gardiner to explain the background.
When the cow was killed by lethal injection, the majority of the temple's worshippers were at morning prayer. The RSPCA had met with Mr Das on Wednesday and he is adamant that at the end of that meeting he was told that the temple would be given time to seek legal advice.
Last night, farm manager Stuart Coyle, described how he rushed to the farm when he heard police had arrived but was stopped by an RSPCA inspector. He said: ''I realised that he was there to cut me off from entering the farm. By the time I made it to the farm she was already dead.''
Tushta Krishna was the last person from the temple to see Gangotri alive. He said: ''I was in the cow shed when they came in. I thought they were simply going to check on her but a part of me worried that they were going to kill her there and then.
''I started to question them and then lost my temper and a police constable took me outside. A few moments later the vet came outside and said 'It's done'.''
The temple admitted that Gangotri suffered from bed sores because she could no longer stand up after she damaged her hind muscles. However they insist she was not suffering from any disease.
