Dietary effects of Ca-zeolite supplementation on some blood and tibial bone characteristics of broilers

Abstract

This study was conducted to investigate the effects of differing amounts of natural Ca-zeolite on bone and some blood parameters. A total of 240 day-old Ross 308 broiler chicks were assigned to four treatments with three replicates, each containing 20 day-old chicks of mixed sex. A clinoptilolite+mordenite type of zeolite was added in the broiler diets at levels of 0 g/kg, 10 g/kg, 30 g/kg, and 50 g/kg. Stocking density was 14 broilers/m². During the six-week trial, blood parameters and bone characteristics were monitored. The inclusion of Ca-zeolite, at various levels, did not have any significant effect on the concentration of blood serum biochemical parameters; serum glucose, cholesterol, total protein, uric acid; concentrations of Ca, P, Na, K, Cl, and on tibial bone characteristics (tibia weight, ash, volume, specific gravity, and Ca and P contents) in the two sexes and mixed-sex between the groups at 21 and 42 days of age.
