There is no ritual slaughter of animals in Ramadan. I don`t know where this question arises.

 

If, however, you mean to ask whether Muslims ought to perform ritual sacrifice in `Eid al-Adha then the answer is: it is not obligatory but only highly recommended for those who can afford to do so.

 

The purpose of which is to commemorate the sacrifice of the great Prophet Ibrahim, offering thanks to Allah, feeding the poor and destitute and celebrating the Feast of sacrifice.

 

Almighty Allah knows best.
