Fiber in Animal Nutrition

73 The following table shows typical fibrous feed stuffs that contribute significant amounts of fiber to a diet. Various analytical methods are commonly used to describe the fiber content of feed stuffs. Here we focus on Weender Analysis, Detergent Analysis and Fiber Content of Feed Stuffs Table 28: Fiber content of typical fibrous feed stuffs Fiber characeriza- tion (as fed basis) Crude Fiber - CF (%) Neutral De- tergent Fiber - NDF (%) Acid Deter- gent Fiber - ADF (%) Acid Deter- gent Lignin - ADL (%) Total Dietary Fiber - TDF (%) Soluble Dietary Fiber - SDF (%) Insoluble Dietary Fiber - IDF (%) % of Insolu- ble Dietary Fiber Cereals Barley 3.9 c 18.29 c 5.78 c 2.28 c 13.1 a 5.37 a 7.54 a 57.60 Wheat >11% CP 2.57 c 10.6 c 3.55 c 0.97 c 9.83 c 2.34 c 6.81 c 69.3 Corn 1.98 c 9.11 c 2.88 c 0.32 c 6.4 1.7 f 4.7 f 73.4 Oats 10.8 d 28 g 13.5 g 2.2 g Sorghum (high tanins) 3 h 9.8 h 4.6 h 0.34 h Rice, brown 1.5 h 12.2 h 5.3 h 1.3 h 3.4 d Cereal by-products Wheat bran 10.2 g 42.8 g 12.8 g 3.5 g 34.7 n 3.6 n 31.1 n 89.7 Wheat middlings 7.5 d 35.7 h 10.7 h 3.34 h Wheat shorts 35 b 41 3.3 b 37.7 b Wheat straw 41.6 f 85 f 54 f 71.5 0.5 f 71.0 f 92 Wheat feed flour 1.5 h Oat bran 3.6 l 14.3 l 4.3 l 2.6 l 18.25 a 7.73 a 10.5 a 57.5 Oat hulls 30.2 h 71.8 b 37 h 6.25 h Rice hulls 44 d 76 h 66 h 15 h DDGS 9.9 f 44 f 18 f 42.9 b 0.7 b 42.2 b 98.4 Rice bran, extr. 14 f 34 f 18.5 f 25.39 o 2.94 o 22.45 o 88.4 Rice polish 5.2 h 4.05 h Corn cob/stalk 34.4 f 67 f 39 f 77.3 f 2.9 f 74.4 f 96.3 Corn bran 8.8 h 43.7 h 14.1 h Total Dietary Fiber. Especially differentiating between soluble and insoluble fiber fractions is important in order to better understand the physico-chemical characteristics of fibrous feed stuffs.
