Portions adapted from: Albin, R.C. and G.B. Thompson. 1996. Cattle Feeding: A Guide to Management. Trafton Printing, Inc. Amarillo, TX.
Acidosis
An acute or chronic disease condition in feedlot cattle. Results from over-consumption or too rapid consumption of grain (starch). Acute cases generally result in death. Chronic cases are common, resulting in erratic intakes and/or reduced feed intake, but are probably hidden by pen intakes which tend to make average consumption look normal. It is one of the most costly problems in the feedlot industry. Sub-acute cases are difficult to diagnose, but symptoms include poor performance and poor conversions.
ADG
Average daily gain. The amount of gain divided by the number of days in the feeding period.
As Is Basis
Feed is sold `as is,' with no adjustments for moisture content. See also: Dry Matter Basis.
Bawling Calves
Calves which are taken directly off the cow and weaned at the feedlot, requiring additional labor and a greater degree of health management by the feedlot.
Breakeven
The sale price ($/cwt) at which the customer or owner of the cattle does not make or lose money.
Buller(s)
Steers which are ridden by other steers in the pen (as with cows or heifers that are `bulling'). If problems persist, animals are usually removed from the pen to prevent bruising, injury, and reduction in performance of the other cattle.
Buller Pen
Pen in which bullers are kept.
Bunk Call or Bunk Reading
Deciding how much feed should be fed and when it should be fed.
The philosophy the feedlot manager uses to determine the amount of feed to offer. See also: Slick Bunk Management.
Bunk Reader
The person at the feedlot who is responsible for deciding the daily amount of feed the cattle are fed. This person is critical to the successful feeding of high concentrate diets. See also Bunk Call, Feed Call, Missing the Call.
Feed ingredients which are produced during the production of human food products (e.g. corn sweetener, flour, cooking oils, sugar) or industrial products (e.g. ethanol, industrial oils). These byproducts are used as ingredients in some growing and finishing diets. See also: Wet Distillers Grains, Wet Corn Gluten Feed.
Cattle which are placed on feed as calves and finished at less than 16 months of age. Usually on feed for 150 to 200 days. These cattle are usually placed in the feedlot directly following weaning. See also: Yearlings.
Carry Cattle
Cattle which are held at the packing plant over a holiday or weekend. These cattle may be penned at the plant for 36 to 84 hours before being slaughtered. These cattle are generally offered feed and water if held for more than 36 hours.
Charging the Bunk
Condition resulting from errors in bunk calls, feed delivery, or inclement weather. Cattle will rush to the bunk when the feed truck comes because they are hungry and overeat, resulting in problems such as acidosis, founder, and other digestive disturbances.
Chronic(s)
Cattle which fail to respond to treatment. See also: Realizer and Railer.
Chute Charges
A fee charged by some feedlots each time cattle are worked through the chute.
Clean Bunk Management
Refers to the bunk management style in which cattle clean up all the feed offered every day. Feed call is increased if cattle have `slicked the bunk.' See also: Charging the Bunk, Bunk Management, and Slicked Up.
Close-Outs
A detailed description of pen performance, feed intake, death loss, and profit or loss. A close-out is generated each time a pen of cattle is sold. Can be calculated on a `deads-in' or `deads-out' basis.
Company Cattle
Cattle which are owned and fed by the feedlot. See also: Customer Cattle.

The feed company provides these services when the feedlot purchases supplements or other feed ingredients from the feed company. See also: Consulting Nutritionist, Private.
Consulting Nutritionist, Private
A private nutritionist hired by the feedlot to give professional opinions on rations, supplements, feed additives, and management practices. Usually paid on a retainer plus a per head fee. See also: Consulting Nutritionist, Feed Company.
Consulting Veterinarian
A veterinarian hired by the feedlot to consult on animal health related issues such as vaccines, treatments, etc. Usually paid on a retainer plus a per head fee.
Cost of Gain
Total of all feedlot-related costs (feed, yardage, processing, medicine, death loss) divided by total gain during the feeding period. Can be calculated on a `deads-in' or `deads-out' basis.

Days on Feed
The number of days the cattle are fed.
Deads In/Deads Out
Lingo which refers to the methods used to calculate closeouts, cost of gains, and breakevens.

Yield Grade
A numerical grade placed on each carcass by the USDA inspector at the packing plant which estimates differences in the yield of boneless, closely trimmed retail cuts from the round, rib, loin, and chuck. Factors determining yield grade include: fat thickness at the 12th rib, ribeye area, hot carcass weight, and the amount of kidney, pelvic, and heart fat. Lower yield grades (1.0) indicate leaner carcasses, while higher yield grades (5.0) indicate fatter carcasses.
