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 raon (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 raon (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 raon (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
digeson method (Kjeldahl),in the raon (Kuku) was 2.94% and in manure was
3.22%,in the raon (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 raon (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 raon (Kuku) 2.01ds/m and in manure 2.9ds/m, in the rao, n (Shambat)
5.01ds/m, and in manure 2.8ds/m, pH in the raon (Kuku) was 5.96 and in
manure 7.16 , in the raon (Shambat) 4.99 and in manure 5.72 respecvely.
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.
