The community and worshippers at the Guru Gobind Singh Gurdwara on Leeds Road said they felt offended by the expansion bid by supermarket chain Pakeezah.
They told planners that hearing carcasses being cut up would upset worshippers at prayer as many Sikhs are strict vegetarians.
But despite their protests, a planning panel at Bradford Council granted the food company permission to convert a car workshop in nearby Percival Street into a wholesale meat plant in August last year.
The Gurdwara's general secretary Govinder Singh Dhaliwal said they were delighted by the Council's decision and were grateful for all the support they had received from Bradford's other religious groups during their fight.
He said, "This decision will strengthen the relationships among the faith communities and their support is a good example of community cohesion. This decision by the Council strengthens our belief in the democratic political process, which has responded to public opinion".
Pakeezah's director Tariq Haq was unavailable for comment.
