| Abstract | ||||
| The composition and feeding value of dried cow manure (CM), poultry manure (PM) and rabbit manure (RM) were indirectly determined for laying hens using yellow corn as a basal. Results of chemical composition of CM, PM, and RM showed acceptable percentage of nutrients. Also there were suitable values of nutrient digestibility and feeding value of such materials. The ME values were 1833, 2226 and 1969 Kcal/Kg of CM, PM and RM, respectively. In feeding trial, 189 Mamoura chickens of 24 weeks old were divided into 7 triplicate groups (9 birds x 3 replicates x 7 treatments). Each replicate contains one cock and eight hens. Seven experimental diets were formulated in which the 1st was the control (T1) and based mainly on yellow corn and soybean meal. A mixture of CM, PM and RM, in a ratio of 1:1:1, was used to replace part of T1 at levels of 10, 15 or 20 % without or with addition of 0.05 % Kemzyme (a commercial mixture of some enzymes, KZ) for T2, T3, T4, T5, T6 and T7, respectively. Laying hen performance, egg quality and economic efficiency were measured along 3 months experimental period. The results of hen performance showed significant superiority of the substitution level 15% with or without KZ supplementation (T5 & T4) followed by those of T3, T2, T7, T1 and T6, respectively. Also there were significant differences in some measurements of egg quality. From the economic point of view, T5 recorded the best value followed by those of T4, T3, T7, T6, T2 and T1 respectively. In conclusion, when the performance of laying hens are taken in consideration in addition to the economic efficiency, it appeared that using a mixture of CM, PM and RM to replace 15% of the laying diets is practically effective and more cheaper final product could be achieved. | ||||
