Abstract
This study evaluated the effect of dietary Cr supplementation on apparent mineral retention in camel calves reared under hot summer conditions. This study were conducted on 15 male camel calves (5 – 6 months old) during hot summer conditions. The animals were divided into three equal groups, 5 animals each, and were housed individually under shelter. During the experimental period (12 weeks) camel calves were fed ad libitum on total mixed ration (TMR) without Cr supplementation, TMR supplemented with 0.5mg Cr/kg DM or TMR supplemented with 1.0mg Cr/kg DM. A metabolic trial for a period of 8 days conducted after 12 weeks of dietary treatments to estimate trace minerals balances. Chromium intake, retention, and digestibility were influenced by dietary chromium (P<0.05), however, dietary supplementation of Cr did not effect) p>0.05) on chromium excretion. Copper digestibility and retention were substantially reduced when 0.5 mg Cr/kg DM added to diet. The retention and digestibility of Fe increased with supplementation of Cr (p<0.05). Zn digestibility significantly decrease with supplementation of Cr up to0.5 mg/kg DM (p<0.05). Plasma Cr level was found not significant higher in 1 mg/kg fed calves. However, plasma concentration of Cu, Zn, and Fe was found tended to decrease with supplementation Cr (p>0.05).
