Effects of Supplementary Levels of Deep-stacked Broiler Litter on Digestibility, Dry Matter Intake, and Nitrogen Balance by Male Spotted Deer(Cervus Nippon)

TLDR: It is suggested that up to 30% of broiler litter may be fed to male deer without deleterious effects on deer performance.

Abstract: To determine nutritive value and suitability of deep-stacked broiler litter for deer, the influence of supplementary levels of broiler litter on digestibility, dry matter intake, and nitrogen balance was investigated in male spotted deer ( Cervus nippon ) fed a commercial mixed(complete) ration. The deep-stacked and ground broiler litter was supplemented at the level of 0%(Control), 15%(T1) and 30%(T2) on the basis of fresh matter to the mixed ration. All treatments had similar palatability at about 3% body weight of dry matter intake. Dry matter digestibility was highest in Control and lowest in T2(P<0.05). Digestibility of crude protein was lowest(P<0.05) in T2. Dry matter and digestible dry matter intake was similar in all treatments. Daily body weight gain was not affected by treatments. Feeding 15 or 30% of broiler litter to male deer resulted in similar nitrogen intake, fecal nitrogen excretion and daily nitrogen retention(g/d), compared with feeding Control. These results suggest that up to 30% of broiler litter may be fed to male deer without deleterious effects on deer performance. (
