This experiment was conducted to use broiler litters and pig manure as alternatives of layer`s manure for making straw-manure silage as well as to determine the digestibility and nitrogen balance in sheep fed rice straw-livestock manure silage. Four sheep averaging 30 kg were used in a digestibility and nitrogen balance trial by 4x4 Latin square design. The four rations tested contained; 1) 4% NaOH treated rice straw-wet layer`s manure silage, 2) 4% NaOH treated rice straw-broiler litters silage, 3) 4% NaOH treated rice straw-pig manure silage, 4) 4% NaOH treated rice straw-dried layer`s manure silage. The pH of the silage containing wet layer`s manure, broiler litters, pig manure and dried layer`s manure was 4.83, 5.16, 4.64 and 4.82 at the 40 days of ensiling, respectively. The acetic acid production of straw-manure silage with wet layer`s manure and pig manure was major dominant acid whereas the acetic acid and lactic acid production in the straw-broiler litters silage and straw-dried layer`s manure silage became equally dominant. The total acids of silage with broiler litters and pig manure were 7.41% and 2.49%, respectively. The apparent digestibilities of dry matter, organic matter, neutral detergent fiber (NDF) and acid detergent fiber (ADF) were similar in the lambs receiving the straw-manure silage regardless of type of manure included. The apparent digestibility of crude protein in the silage containing dried layer`s manure was significantly lower than the silages of pig manure, broiler litters and wet layer`s manure (P$lt;0.05). There was little differences in nitrogen balance. The total digestible nutrients (TDN) value of straw-manure silage containing wet layer`s manure, broiler litters, pig manure and dried layer`s manure was determined as 53.36%, 54.50%. 53.57% and 49.86% respectively.
