Yamashita, T., Tobisa, M., Ohgushi, A. and Furuse, M. 2001. Enhancement of plasma calcium concentration by dietary calcium sources and oligosaccharides in neonatal chicks. J. Appl. Anim. Res., 19: 25–32.
The effects of dietary calcium (Ca) sources and several oligosaccharides on plasma Ca concentration were examined in the neonatal cluck. In the first experiment, the efficiency of Ca carbonate and eggshell Ca teas compared by determining plasma Ca concentration at 15, 30, 60 and 120 min post oral administration. It was significantly higher in the eggshell Ca treatment than in the Ca carbonate treatment and the peak for plasma Ca concentration was obtained at 30 min. The effect of dietary oligosaccharides on plasma Ca concentration was investigated by nsmg isomaito-oligosaccharides, gentiooligosaccharides and nigerooligosaccharides with Ca carbonate. In the second experiment Nigerooligosaccharides enhanced plasma Ca concentration when compared with other treatments. The efficacy of lactose and nigerooligosaccharides on plasma Ca concentration was compared in the third experiment, but no significant, difference was detected between them. These results suggested that plasma Ca concentration of the neonatal chick can be modified, by dietary Ca sources and the supplementation with specific oligosaccharides.
