| Abstract |
The main target of this study was to evaluate the effect of high levels of radicel, as a non-conventional feedstuff, with or without enzymes on broiler performance. In this study, two levels of radicel (15 and 20% of the diet) in addition to the control diet (without radicel) were used. Each level of radicel was fed either without enzyme, with a commercial enzyme mixture E1, Kemzyme (at 1 g/kg diet) or a commercial enzyme mixture E2, Prismazym Veg (at 2 g/kg diet). Accordingly, a total of 7 experimental diets (2 levels of radicel x 3 treatments), in addition to the control (without radicel) were used A total number of 210 unsexed one day old Ross broiler chicks were distributed randomly and divided equally into seven experimental groups nearly equal in average live weight. Each group was represented by 30 birds in three replicate pens of 10 chicks each and kept under similar management conditions. All diets were formulated to be isocaloric and isonitrogenous in each of the experimental stages according to the strain catalog recommendation. Radicel (malt sprouts) is a byproduct of barley germination, left after removing barley malt.
The results of this study showed that radicel contained moderate amounts of major nutrients, especially CP (20.14%) and NFE (54.24%), but it contained high level of CF (14.21%) and 24.84% ADF (cellulose + lignin). It is rich in (ppm): 7250 Na, 4900 total P, 4125 K, 3000 Fe, 2050 Mg, 425 Cu, 120 Zn and 30 Mn. In comparison to the NRC (1994) requirements of the chicks, arginine and methionine were the first limiting amino acids (0.76), while isoleucine (0.80) and phenylalanine (0.83) were the second and third limiting amino acids, respectively. Radicel at 15% without enzyme supplementation gave better performance than that with enzyme supplementation but still less than the control. Radicel at 15% with or without enzymes did not decrease carcass percentage or digestion coefficient values of the nutrients as compared with the control. While, 20% radicel without enzyme decreased both of them. From economic point of view, 15% radicel without enzyme supplementation gave best economic efficiency and relative economic efficiency, followed by 20% radicel + E1
as compared with the control. However, E2 was not as effective as E1 under the condition of this experiment.
