BRUSSELS, Nov 12 (Reuters) - Anheuser-Busch InBev (ABI.BR), the world's top brewer, grew quarterly core earnings by slightly more than expected thanks to cost cuts and higher prices, and forecast a similar profit rise in the last three months.

A year after its creation from Belgian InBev's takeover of U.S. rival Anheuser-Busch, the maker of Budweiser, Stella Artois and Beck's said on Thursday prices, lower input costs and merger savings enabled it to offset a 3.2 percent fall in volumes.
