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

AbstractTo 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. (

TL;DR: Most common dietary responses in metabolite uptake by PDV are changes in uptake of ammonia and volatile fatty acids, which emphasize the strong energy: nitrogen interrelationship in the rumen and subsequently the rest of the body.
Abstract: Major functions of portal-drained viscera (PDV) and liver of cattle include absorption of digestion products and modification of the body's supply of intermediary metabolites. The disproportionately high metabolic rate of PDV and liver (7-13% of body tissues) is exemplified by their oxygen uptake (40-50% of whole body). Extensive metabolism of glucose, volatile fatty acids and amino acids by PDV modulates nutrient supply from the diet such that most responses to diet or physiological state are a function of level of diet intake. Similarly, blood flow through PDV is highly correlated with energy intake across a range of body weight, physiological state or diet composition. Most common dietary responses in metabolite uptake by PDV are changes in uptake of ammonia and volatile fatty acids, which emphasize the strong energy: nitrogen interrelationship in the rumen and subsequently the rest of the body. The liver (tissue in series with PDV) removes glucose precursors and ammonia from its blood supply as part of its functions in gluconeogenesis, ammonia detoxification and urea synthesis. The liver also alters amounts and proportions of amino acids supplied by PDV. Accountable percentages of metabolizable energy from net PDV supply include: organic acids, 41-59%; amino acids, 5-13%; and heat energy (from oxygen uptake), 11-22%.
