| Abstract |
Fifteen growing ostriches of 5 months of age were used in the present work to study the effect of completely replacing soybean meal (SBM) with either corn gluten meal (CGM) or cotton seed meal (CSM) and completely replacing (CH) with radicel (RCL) in ostrich diets on the their growth performance, feeding value and some blood constituents taken in consideration the economic aspects. The birds were distributed into 5 groups of 3 birds each and reared under similar management conditions from 5 to 12 months of age in suitable separated courts.
Five experimental diets were formulated in which the 1st contained mainly from yellow corn, SBM and CH as common sources of energy, protein and fiber, respectively and served as a control diet (T1). The 2nd diet (T2) was as T1 but SBM was completely replaced by CGM. The 3rd diet (T3) was as T2 but CH was completely replaced by RCL. The 4th diet (T4) was as T1 but SBM was completely replaced by CSM, while the 5th diet (T5) was as T4 but CH was completely replaced by RCL. The grower diets were adjusted to be isonitrogenous of about 19 % CP and isocaloric of about 2450 Kcal, ME/Kg and fed to the birds up to 9 months of age. The finisher diets were formulated as the same manner of the grower diets but less in CP (17.5%) and energy (2300 Kcal, ME/Kg) and fed to the birds up to 12 months of age. At the end of the experiment, five digestibility trials were conducted to determine the nutrient digestion coefficients and feeding values of the experimental diets. Also some blood samples were taken to measure some blood constituents for the experimental treatments. An economic study was also carried out.
The obtained results showed that the group in which SBM was completely replaced by CGM (T2) resulted in nearly similar values of growth performance and feeding value to those of the control group (T1) without significant differences between them. The groups of CSM and CSM + RCL (T4 and T5) showed significantly inferior results in growth performance and feeding values compared to those of T1 and T2. No significant differences were detected between those two groups (T4 & T5). The group in which SBM and CH of their diets were completely replaced by Abbas, A. M. et. al., 390
CGM and RCL, respectively (T3) resulted in intermediate values between the first two groups (T1 & T2) and the last two groups (T4 & T5). Statistically, this group (T3) tended to be similar to those of T2. The results of the digestibility trial confirmed the performance. The blood constituents did not reveal clear cut trend and most measurements were significantly similar. Regardless the control group, the group of T3 resulted in the best economic efficiency among all dietary treatments. It could be generally concluded that CGM, CSM and RCL could be used in feeding ostriches as untraditional feedstuffs although they failed surpassing the control group. However, such ingredients may be give better results when their substitution levels being less than 100 % to obtain better results from the nutritional and economical points of view.
