Effect of concentrates restriction on feed consumption, diet digestibility, and nitrogen utilization in captive Asian elephants (Elephas maximus).

In order to study the effect of concentrates restriction on feed consumption, diet digestibility, and utilization of nitrogen in captive Asian elephants (Elephas maximus), 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 dry matter (DM) basis, respectively. During trial II, the amount of concentrate was reduced by 50%.

Nutrient intake, digestibility, and blood metabolites of goats fed diets containing processed jatropha meal.

This study was conducted to record the ideal source and level of alkali treatment to treat jatropha meal (JM) and to determine the effect of inclusion of variously processed JM (pJM) on nutrient intake, digestibility, blood metabolites and hormonal status in goats. The JM was treated with 10 g/kg sodium chloride and 5 g/kg calcium hydroxide. The content of phorbol ester and hemagglutination (HA) activity of JM and pJM were assessed.

Effect of concentrate supplementation on feed consumption, nutrient utilization and blood metabolite profile in captive spotted deer (Axis axis) fed oat (Avena sativa) and berseem (Trifolium alexandrinum) fodders based diet.

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.
