Abstract/OtherAbstract:
This experiment was conducted to determine the optimum level of a maize-soybean meal-wheat bran concentrate supplement fed to captive spotted deer fed an oat and berseem fodder-based diet. Twelve adult spotted deer [64-76 kg body weight (BW)] were distributed into three groups of four each and were housed individually. A diet consisting of 5 kg of oat fodder and 5.5 kg of berseem fodder was offered to each one of the experimental animals. The animal in group I received no supplementary concentrate, whereas, those in groups II and III received 0.5 and 1 kg of supplementary concentrate, respectively. A 60 days digestibility trial was conducted with a 5 days collection period on Days 55-59 of the trial. Blood samples were collected from all animals on Day 60 of the experiment. Average daily dry matter intake (DMI) was 1,224, 1,613, and 1,574 g/day in groups I, II, and III, respectively. Dry matter (DM) and organic matter (OM) intake was lowest (P < 0.01) in group I. Intake of P, Cu, and Zn was highest (P < 0.01) in group III, followed by groups II and I. Digestibility of neutral detergent fiber was highest (P < 0.05) in group II. Digestibility of OM and CP was lowest (P < 0.05) in group I. Digestibility of gross energy was highest (P < 0.01) in group III (74.9%), followed by groups II (69.3%) and I (66.2%). Digestible energy (DE) intake (kcal/kg BW(0.75) ) was highest (P < 0.01) in group III (195.4), followed by groups II (180.9) and I (129.8). Initial BW was 72.7, 72.5, and 71.0 kg, whereas, final BW was 71.0, 72.7, and 73.5 kg, in groups I, II and III, respectively. Average daily change in body mass was significantly (P < 0.01) different among the groups. The body mass was lost (-29.2 g/day), maintained (4.1 g/day) and gained (41.6 g/day) in groups I, II, and III, respectively. Blood glucose and cholesterol concentration was highest (P < 0.05) in group III, followed by groups II and I. Serum concentration of Cu and Zn was highest (P < 0.05) in group III, followed by groups II and I. Supplementation of forage only diet with 0.5 kg of concentrate mixture increased intake and digestibility of nutrients, without change in body mass. Animals fed 1 kg of supplementary concentrate received energy in excess of requirements, were consistently gaining body mass and were prone to obesity. Thus, it is a right strategy to supplement forage only diet of captive spotted deer with 0.5 kg of concentrate. Zoo Biol. XX:XX-XX, 2013. © 2013 Wiley Periodicals Inc.
