SUMMARY

As has been mentioned in the first part of this study (Tibin and Koko, 1989) the effect of using sun dried poultry manure (S.D.P.M.) in broiler diets as a source of crude protein on broiler performance and eviscerated yield component parts was investigated. The present study ‘dealt with the effect of using S.D.P.M. on meat and bone yields, non-carcass components and car- cass chemical composition. Design of the experiment and diet treatments were reported in pan (I) of this series. Results obtained have shown that as the level of S.D.P.M. increased, the bone yields of commercial cuts increased significantly, while the muscle yield decreased. On the other hand, the weight of head, shank and total viscera as a percentage of liveweight increased as the level of S.D.P.M. increased in the broiler diets. However, the use of S.D.P.M. did not affect liver, gizzard and heart weights expressed as percentages of liveweight. Carcass chemical composition showed that with the increase of the level o_f S.D.P.M. in broiler diets, carcass crude protein decreased, carcass ash and carcass fat increased, while the carcass moisture was not affected.
