Analysis of Chicken Ration and its Effect on the Quality of Chicken Manure

Abstract

In this study chicken rations and chicken manure from two poultry farms were sampled and analyzed to study the effect of the quality of rations feed to poultry on manure quality. Samples were collected from poultry farm of Sudan University of Science and Technology (Shambat) and from that of National Veterinary Research Center (Kuku). The laboratory analysis was done in ENDRI, National Center for Research, Khartoum.The samples were analyzed for some chemical and physical characteristics. flame emission spectrometric of alkali metals (Na, K) in the rað€€¯on (Kuku) gave 0.26*10-2 mg/L, 0.31*10-2 mg/L and in manure with 0.32*10-2 mg/L, 0.34*10-2 mg/L, the rað€€¯on (Shambat) gave 1.8*10-2 mg/L, 6.0*10-2 mg/L and in manure gave15.8*10-2 mg/L,4.4*10-2 mg/L respectively, and Atomic absorption spectrophotometric of trace minerals (Mn, Co, Cu, Fe, Zn) in the ration (Kuku) gave 0.274*10-3 mg/L ,0.036*10-3 mg/L ,0.155mg/L , 0.343*10-3 mg/L ,0.226*10-3mg/L and in manure gave 0.476, 0.033*10-3 mg/L,0.233*10-3 mg/L, 1.288*10-3 mg/L, 0.448*10-3 mg/L, the rað€€¯on (Shambat) gave 0.215*10-3 mg/L, 0.022*10-3 mg/L, 0.087*10-3 mg/L, 0.590*10-3 mg/L, 0.221*10-3 mg/L and in manure gave 0.590*10-3 mg/L, 0.036*10-3 mg/L, 0.329*10-3 mg/L, 1.834*10-3 mg/L, 0.742*10-3 mg/L . Nitrogen content% which was determined by using digesð€€¯on method (Kjeldahl),in the rað€€¯on (Kuku) was 2.94% and in manure was 3.22%,in the rað€€¯on (Shambat) was 6.3% and manure was 3.0%. Phosphorus was estimated spectrophotometrically in the ration (Kuku) to gave 0.7*10-3mg/Land in manure 1.0*10-3mg/L in the rað€€¯on (Shambat) to gave 0.8*10-3 mg/Land in manure , 2.0*10-3 mg/L. EC and pH, which were measured using EC-meter, gave in the rað€€¯on (Kuku) 2.01ds/m and in manure 2.9ds/m, in the rað€€¯o, n (Shambat) 5.01ds/m, and in manure 2.8ds/m, pH in the rað€€¯on (Kuku) was 5.96 and in manure 7.16 , in the rað€€¯on (Shambat) 4.99 and in manure 5.72 respecð€€¯vely. Results of analysis revealed that the ration used in poultry farms affected manure quality and mainly for fertilization programs. This confirmation of the hypothesis of the first and third.
