I think the closest is Jainism.

Compassion for all life, both human and non-human, is central to Jainism. Human life is valued as a unique, rare opportunity to reach enlightenment. To kill any person, no matter their crime, is considered unimaginably abhorrent. It is the only religion that requires monks and laity, from all its sects and traditions, to be vegetarian.

History suggests that various strains of Hinduism became vegetarian due to strong Jain influences.[27]. Jains run animal shelters all over India. For example, Delhi has a bird hospital run by Jains. Every city and town in Bundelkhand has animal shelters run by Jains where all manner of animals are sheltered, even though the shelter is generally known as a Gaushala ("sacred cow").

Jainism's stance on nonviolence goes far beyond vegetarianism. Jains refuse food obtained with unnecessary cruelty. Many practice a lifestyle similar to veganism, due to the violence of modern dairy farms, and others exclude root vegetables from their diets to preserve the lives of these plants.[28] Potatoes, garlic and onions in particular are avoided by Jains.[29]. Devout Jains do not eat, drink, or travel after sunset, and prefer to drink water that is boiled and then cooled to room temperature.[citation needed] Many Jains abstain from eating green vegetables and root vegetables one day each week. The particular day, determined by the lunar calendar is Ashtami (eighth day of the lunar month), New Moon, the second Ashtami and the Full Moon night.
