Bammoth require different amounts of grown vs harvested Nosh Sprout

Per both the wiki.gg wiki (which pulls critter diet data directly from game files) and the in-game encyclopedia, a single bammoth requires 14.17% Nosh Sprout growth or 1.6 units of nosh beans per cycle.

A nosh sprout takes 21 cycles to mature; therefore it grows 4.76% per cycle.  A bammoth therefore needs to directly consume (14.17/4.76=) 2.98 nosh sprout plants. (the rounded number in the in-game encyclopedia is 14% per cycle, which would = 2.94 plants)

A nosh sprout produces 12 beans every 21 cycles, this = .57 beans per cycles.  A bammoth therefore requires 1.6/.57=2.8 harvested nosh sprout plants.

I'm guessing this is unintentional, as every other critter that can both directly and indirectly consume a plant requires equal amounts (including the bammoth itself when eating Plume Squash).
