Thesis Abstract

Studies were carried out to examine the output, proximate composition, carbon to nitrogen ratio and energy value of poultry litter. Excreta was collected from broiler chicken and caged layers. Excreta collected was subjected to gross chemical analysis and gross energy determination. The results showed the output of broilers to be 154g per bird per day while that of layer was 86.5g.Result obtained from the proximate analysis of the broiler and layer litters showed that broiler litter had a moisture content of 31.79% (68.1% dry matter), 10.06% crude protein, 6.1% ether extract, 16.62% crude fibre, 18% ash and 15.90% nitrogen free extract whereas layer litter had 29.06% moisture content (70.94% dry matter), 8.54% crude protein, 5.5% ether extract, 12.5% crude fibre, 23.75% ash, 20.65% nitrogen free extract on dry matter basis while on fresh basis (wet basis) broiler had 6.87% crude protein, 12.31% ash, 11.30% crude fibre, 4.16% ether extract and 10.83% nitrogen free extract whereas layer had 6.06% crude protein, 16.70% ash, 8.88% crude fibre, 3.90% ether extract and 14.93% nitrogen free extract. The average gross energy of broiler litters was 7.61MJ/kg while that of layer was 6.40MJ/kg, the carbon to nitrogen ratio of broiler litter was 17.53 while that of layer litter was 19.27 (on dry matter basis). On fresh basis the average gross energy of broiler litter was 5.19MJ/kg and that of layer was 4.36MJ/kg, the carbon to ratio of broiler was 11.92 while that of layer was 13.14.
