Abstract
A total of 180 Mamoura thickens (162- hens and 18 cocks) 24 weeks old were randomly devided into 6 triplicate groups (10 beds x 3 replicates x 6 treatments) each replicate contains one cock and nine hens. They were reared in conventional floor brooder houses under similar management conditions and fed on the experimental diets for 24 weeks experimental period. Six experimental diets were formulated in which the frist (T1) contained soybean meal (SBM) and yellow corn (VC) as the main sources of protein and energy, respectivly, and served as a control diet. In the other diets SBM in T1 was completely replaced by either cotton seed meal (CSM-T2) , con, glutin meal (CGM-T3), sesame seed meal (SSM-T4), molasses grown yeast (MGY-T5) or a mbcture of them (MIX-T6). All diets, were adjusted to be [so-nitrogenous of about 16 % CP and iso-caloric of a bout 2800 Kcal ME/Kg. laying hen performance, egg quality, fertility and hatchability were measured. A metabolism trial was also carried out to determine the nutrient digestibilities and metabolizabilities of the exprimental diets. Some blood constituents were also measured. The obtained results showed significant differences among treatments in the averages of body weight, weight gain, egg production, egg mass and feed conversion, whereas, egg weight and feed intake values were not significantly different. The general descending ranking order of the performance data was T1 followed by T3, T6, T2, T5 and 14, respectively. Significant differences were also found in fertility, hatchability and embryonic mortality. The general statistical trend was such as that of the performance data. Once again, significant differences were detected between treatments in nutrient digestibditles and metabolizabilities, egg quality and some blood constituents. From the economic point of view, T1 recorded the best economic efficiency followed by T5, T6, 17, 13 and T4, respectively, in a descending ranking order. In conclusion, when the performance of laying hens are put into consideration, in addition to the economic efficiency, it appeared that the inclusion of MGY or CSM to completely replace of SBM in laying hen diets is economically effective. A combination of all plant protein sources as in MIX-diet (T6) could be occasionally used to solve a part of SBM shortage.
