stocker

1. (agriculture) Livestock that is wintered and then sold in the spring; often contrasted with a feeder when the focus is on intended disposition.Examples: "When sheep are shipped as stockers from the ranges, the numbers are such usually as to admit of grading the animals before they are shipped."; "The production of stockers and feeders should be confined to those parts of the country where the larger part of the land cannot be plowed profitably, and grass is the principal crop."; "All feeder calves wintered and sold in the spring are stockers, whether they go to grass or to the feedlot."

2. (automotive) A racecar in certain classes of auto racing whose origins are nominally or notionally related to factory-stock autos, such as stock car racing or super-stock drag racing.Examples: "For a starter, a complete technical analysis of the winningest NASCAR stocker of all time, Richard Petty’s 1967 Plymouth Belvedere."; "Ford Motor Company’s response to the Charger 500 was the 1969 Talladega and Cyclone Spoiler II, sleek, slippery stockers that forced Dodge designers back to the drawing board."; "Any small-block Chevy engine, whether it be a stocker, street rod, or racer, will benefit from proper balancing."
