This study was conducted to evaluate manure of dairy cow and sheep through measuring chemical composition and utilization in fattening cattle rations.Animal wastes)As air dried,were collected
in summer and used in winter.Two rations,namely A and Bontaining sheep manure (15%),and dairy cow manures were formulated and fed toHoistein bull calves.Average daily gain (ADG)of the bulls,and feed conversion were measured.
Average chemical composition of the sheep manure was water 2.4, Crude protein 13.7, crude fiber 29.9, crude fat 3.2 , ash 22.0, Nitrogen—free extract 28.6, calcium 3.2and Phosphorus, 0.6, percent. The same composition for dairy cow manure was water 6.7, crude protein 11.9, crude fiber 30.2— ash 21.8, NFE, 26.9, calcium 2.9, and Phosphorus 0.55 percent. The results on feeding trial shewed that the average daily gain of the bulls were 1076 and 1019 grams for rations A and B,respectively; The differerence between these two means statistically not being significant.Feed conversion of the bulls fed with ration B was higher, (7.8) than those animals which received ration A(8.2 ) ; however the difference was small and non significant.There was no problem in feeding animal wastes as far as,Palatability was concerned.
