Abstract

|
An experiment was conducted to determine suitability of broiler litter for a dietary supplement examining dry matter intake, digestibility and nitrogen balance in spotted deer (Cervus nippon) fed commercial mixed ration. The fermented broiler litter was supplemented at the levels of 0 (Control), 15 (BL15) and 30% (BL30) on the basis of fresh matter to commercial mixed ration. Three female spotted deer were allocated to a 3 × 3 latin square design for experiment and were given three experimental diets. Dry matter intake was significantly higher (P$lt;0.05) in BL30 than in control and BL15. Dry matter digestibility decreased according to increasing the supplementary level of fermented broiler litter and there was significant difference (P$lt;0.05) between Control and BL30. Retained nitrogen was highest in BL15 and lowest in BL30, however there were no significant differences among treatments. The ratio of retained nitrogen to nitrogen intake was significantly lower (P$lt;0.05) in BL30 than in others. Consequently, fermented broilor litter could be used up to from 15 to 30% in deer feed source without any harmful effect on deer performance.
