UNASSIGNED: In order to study the effect of concentrates restriction on feed consumption, diet digestibility, and utilization of @entity1568 in captive @entity7105 ( @entity7105 ), two feeding trials were conducted on three juveniles, four sub-adults, and three adults. During trial I, the conventional zoo diets of juveniles, sub-adults, and adult contained 22, 17, and 16% of concentrates on @entity62 ( @entity62 ) basis, respectively. During trial II, the amount of concentrate was reduced by 50%. A digestion trial of five days collection period was conducted during each period. The animals ate more roughages when concentrates were restricted. Intake of @entity62 (g/kg BW(0.75) /day) was highest in sub-adults, followed by juveniles and adults. Apparent digestibility of @entity1131 ( @entity1131 ), neutral detergent soluble (NDS), and supply of digestible energy (DE) was highest in juveniles, followed by sub-adults and adults. Based upon the estimated metabolic fecal @entity1568 (MFN) and calculated endogenous urinary @entity1568 (EUN) and dermal losses, minimum dietary @entity1131 required to meet maintenance requirement was estimated to be 6.12, 6.05, and 5.97% in juveniles, sub-adults, and adults, respectively. Restriction of concentrates resulted in decreased (P   <   0.05) digestibility of @entity62 and GE, but the diet still supplied adequate amounts of DE and @entity1131 to fulfill estimated requirements of energy and protein during the period of experimentation. Thus, the concentrates portion of the diets of captive @entity7105 should be fed in a restricted way so as to reduce the intake of excessive calories and the potential risk of @entity28 .
