Dear Shah Rucksana Akhter Urme thank you for your interesting technical question. In addition to the useful links provided by Martin Hofmeister and Arvind Singh please also have a look at the following relevant reference:

The antibacterial action of vancomycin

Article The Antibacterial Action of Vancomycin

Check http://www.fao.org/3/y5159e/y5159e08.htm

Vancomycin is used to treat serious bacterial infections. It is an antibiotic that works by stopping the growth of bacteria. This medication is usually given by injection into a vein. https://www.webmd.com/drugs/2/drug-939/vancomycin-intravenous/details

Vancomycin, long considered a “drug of last resort,” kills by preventing bacteria from building cell walls. It binds to wall-building protein fragments called peptides, in particular those that end with two copies of the amino acid D-alanine (D-ala).

I am agreed with dear Chinaza Godswill Awuchi 

It's antibacterial not recommended to be used for growth promotion neither disease prevention

Dear Shah Rucksana Akhter Urme thanks for your interesting question. Vancomycin is an antibacterial agent, not recommended for growth promotion or disease prevention. It kills bacteria by disrupting bacterial cell-wall synthesis. Please have a look at the following link- https://tmedweb.tulane.edu/pharmwiki/doku.php/vancomycin#:~:text=Mechanism%20of%20Action%3A,matrix%20(see%20glycopeptide%20pharm).

Its an antibiotics to be used under strict medical advice and supervision.
