Feeding value of dried fermentation biomass in broilers and its effects on production performance, caloric efficiency, and intestinal morphometry
2018
Lumbo, N.B.
Two experiments were conducted to measure the concentration of nitrogen-corrected apparent metabolizable energy (AMEn) in 2 different sources of dried fermentation biomass from monosodium L-glutamate production) in broilers (Exp. 1) and to determine the effect of increasing levels of different sources of DFB on broiler growth performance (Exp. 2). In Exp. 1, 42 day-old (Cobb 500) male broilers were individually housed in metabolic cages and allotted to 3 experimental diets using a completely randomized design with 14 replicates per diet. A corn-soybean meal basal diet and 2 diets consisting of 80% basal diet and 20% DFBI (IVP73L, Intraco BV, Belgium) and DFB2 (PL68, Intraco BV, Belgium) were formulated. The AMEn of DFBI (3,582 kcal/kg DM) was less (P0.05) than AMEn of DFB2 (4,087 kcal/kg DM. In Exp. 2, 700 day-old (Cobb 500) straight-run broilers were randomly allotted to 7 dietary treatments using a randomized complete block design with 10 replicate pens and 10 birds per pen. Phase 1 (d 0 to 10) and phase 2 diets (d 11 to 24) with increasing levels (0, 1, 2 and 3%) of DFBI and DFB2 were formulated. The BW, ADG, ADFI, and F/G were determined. From d 0 to 24, broilers fed increasing levels of DFB1 had no effect on growth performance; however, DFB2 linearly reduced (P0.01) ADG and F/G. In conclusion, energy concentration and feeding value of dried fermentation biomass in broilers vary between sources.
