The Metabolizable Energy Content of Wheat and Animal Products for the Chick

Abstract

The nitrogen corrected metabolizable energy (MEn) and nitrogen content of wheat, menhaden fish meal with and without solubles, and ring dried blood meal were determined. The WS-3 hard red spring wheat was grown in North Dakota (I), Oregon (II), and the Imperial Valley in California (III) and WS-1 hard red spring wheat was also grown in Oregon (IV) during the same year. The nitrogen levels of I, II, III, and IV were 3.0, 2.6, 2.3, and 2.6% on a dry matter basis. Differences occurred by location grown but not by variety. The MEn levels were 3.46, 3.47, 3.48, and 3.44 kcal/gdry matter for I, II, III, and IV. These values were 78, 79, 80, and 79% of the gross energy (GE). The nitrogen content of menhaden fish meal (MFM), 11.0%, was less (P<.05%) than that of menhaden fish meal with solubles (MFMS) which was 11.3%, dry matter basis. The determined MEn values of MFM and MFMS on a dry matter basis were 3.14 and 3.12 kcal/g of dry matter, or 67 and 68% of GE. An animal protein blend contained 11.1% nitrogen and 3.12 kcal/g of dry matter which was 68% of GE. These values were similar to those obtained for MFM and MFMS. Ring dried blood meal contained 15.8% nitrogen on a dry matter basis, indicating it contained 98.75% protein, assuming N X 6.25 equals crude protein. It contained 3.81 kcal MEn/g of dry matter which was 61% of GE.

Nutrient Digestibility of Common Feedstuffs in Extruded Diets for Sunshine Bass Morone chrysops♀×M. saxatilis ♂

“…In fact, the ADCs of all nutrients in Select@ menhaden fish meal were significantly greater for sunshine bass than those in the synthetic analog, although the gross nutrient profiles were similar. PROPAKm has been used extensively over the last 20 yr as a successful replacement for fish meal in poultry diets at levels ranging from 4-10% depending on species and life stage (Nelson et al 1980). Exact composition of the fish meal analog is proprietary; however, promotional literature for the product suggests it is a blend of animal and marine by-products which includes blood meal, fish meal, and fish solublesproducts relatively well digested by fish (NRC 1993;Bureau et al 1999).…”
