CHICAGO, Nov 16 (Reuters) - CME Group lean hog futures rallied on Tuesday, supported by fund buying and expectations that supplies will begin to tighten in the coming weeks, traders said.

Live cattle futures eased slightly for the second day in a row as the market waited for fresh bullish inputs before driving prices above the 4-1/2-year high hit on Friday. Firm cash markets kept the declines in check, traders said.

CME December lean hogs rose 1.925 cents to 77.725 cents per pound and February hogs ended up 2.1 cents at 83.275 cents.

CME's most-active February live cattle contract dropped 0.225 cent to 136.1 cent per pound. The spot December contract eased 0.5 cent at 131.725 cents per pound.

Wholesale boxed beef prices were weaker, with choice cuts falling 15 cents to $283.05 per cwt and select cuts dropping $1.11 to $266.17 per cwt on Tuesday morning.

CME January feeder cattle futures added 0.8 cent to end at 159.275 cents per pound.

Analysts were expecting a U.S. Agriculture Department report on Friday to show that the number of cattle on feed as of Nov. 1 stood at 99.8% of the year-earlier total. Placements during October were 102.2% of the October 2020 total. (Reporting by Mark Weinraub; Editing by Devika Syamnath)
