 THE PREVENTION OF CRUELTY TO ANIMALS ACT

If any person―

(h) being the owner of [any animal] fails to provide such animal with sufficient food, drink or shelter;

he shall be punishable, [in the case of a first offence, with fine which shall not be less than ten rupees but which may extend to fifty rupees and in the case of a second or subsequent offence committed within three years of the previous offence, with fine which shall not be less than twenty-five rupees but which may extend to one hundred rupees or with imprisonment for a term which may extend to three months, or with both].[20]

In 2011, the Animal Welfare Board of India (AWBI) confirmed that starvation forced moulting a punishable offence under India’s Prevention of Cruelty to Animals Act and ordered all farms to discontinue the practice.[21]

如果任何人

(h)作為任何動物的飼主，卻沒有提供牠充足的食物、飲水或遮蔽。

應對其進行處罰，[如果是初犯，應處以不少於10盧比的罰款，但可加重至50盧比；如果是在前次犯罪後三年內第二次或再次犯罪，應處以不少於25盧比但可加重至100盧比的罰款，或處以可加重至三個月的監禁，或同時處以這兩種懲罰]

2011年，印度動物福利委員會（AWBI）確認，根據印度《防止虐待動物法》，禁食禁水強迫換羽是應受懲罰的罪行，並命令所有農場停止這種做法。

對以剝奪飼料及飲水來強迫換羽的間接禁令（由印度動物福利委員會明確規定的），沒有任何例外。
