Rumen protected fat in kline barley or corn diets for beef cattle: digestibility, physiological, and feedlot responses.
A rumen protected fat product composed of Ca salts of fatty acids (CAF) was evaluated in beef cattle diets. Dietary treatments in a metabolism trial (six steers, 251 +/- 15 kg) and Feedlot Trial 1 (15 individually fed heifers, 355 +/- 11 kg) consisted of 62.1% corn and 3.2% soybean meal (C), 32.6% corn and 33.1% Kline barley (CB), and 28.2% corn, 33.1% barley, and 4.5% CAF (CBF) on a DM basis. ...
متن کاملEffects of graded levels of potato by-products in barley- and corn-based beef feedlot diets: II. Palatability.
The objective of this study was to evaluate the effects of barley- or corn-based diets containing 0, 10, or 20% potato by-product (DM basis) on Warner-Bratzler shear force and palatability of beef. One hundred forty-four crossbred beef steers (333+/-.44 kg) were allotted within weight block (3) to a randomized complete block design with a 2 x 3 factorial arrangement of dietary treatments. Main ...

متن کاملnishing diets for feedlot cattle
Commercial sugarbeet yields range between 50 and 100 t clean beets/ha, with sugar concentrations of 17 to 18% on fresh weight (8 to 18 t sugar/ha; Milford, 2006). For 2010, beet yields in the U.S. averaged 62.2 t/ha. However, in the Imperial Valley (predominant cattle feeding region for the state of California), clean beet yields averaged 98.8 t/ha (USDA, 2010); 9 Imperial Valley beet growers t...
متن کاملComparing Cost versus Benefits of Corn Processing for Feedlot Cattle
Corn processing techniques differ in their effects on feedlot performance and carcass characteristics of finishing cattle. Capacity of a feedlot (critical mass) can dictate which processing method is most feasible economically due primarily to fixed costs for equipment. The local and regional corn pricing basis and availability of other ration ingredients also can influence which corn processin...
