contemporaries - Group of animals of the same sex and breed (or similar breeding) that have been raised under similar environmental conditions (same management group).
continental breed - See European breed.
continuous grazing - A method of grazing where animals have unrestricted access to an entire grazing unit throughout a large portion or all of a grazing season.
controlled grazing - Grazing management designed to improve utilization of forage either by 1) allocating pasture in subunits with grazing periods typically less than 5 days or 2) varying stocking rate to match forage growth rate and availability (put-and-take stocking).
cooler - A room in packing plant where carcasses are chilled after slaughter and prior to processing.
corpus luteum - Yellowish body in the ovary. The cells that were follicular cells develop into the corpus luteum, which secretes progesterone. It becomes yellow in color from the yellow lipids that are in the cells.
correlation coefficient - Measure of how two traits vary together. A correlation of +1.00 means that two traits will move in the same direction (either increase or decrease). A correlation of -1.00 means that as one trait increases the other decreases--a perfect negative, or inverse, relationship. A correlation of 0.00 means that as one trait increases, the other may increase or decrease--no consistent relationship. Correlation coefficients may vary between +1.00 and -1.00.
cost of gain - Total of all costs divided by the total pounds gained; usually expressed on a per-pound basis.

creep feeding - See creep.
creep grazing - The practice of allowing calves to graze areas that cows, with a lower nutritional requirement, cannot access.
crest - Bulging, top part of the neck on a bull.
