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/m 2 . 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. ________________________________________________________________________________________________

The welfare of slow growing broiler genotypes reared in organic system

“…Hence, according to the current research fi ndings, slow-growing broiler welfare indicators are similar to each other, resulted in an improvement in the greater the organic housing conditions. Cholesterol and uric acid concentrations are ranged from 97.59 to 120.87 mg/dL and 3.67 to 5.56 mg/dL which are also in agreement with previous data reported by Silva et al (2007) and Eleroğlu et al (2011) who studied in conventional system.…”

Efficacy of Supplemental Natural Zeolite in Broiler Chickens Subjected to Dietary Calcium Deficiency

“…Sodium aluminosilicate influences the metabolism of elements, as evidenced by changes in serum and bone in chicks (Watkins and Southern, 1991;Evans and Farrell, 1993;Eleroğlu et al, 2011). The beneficial effect of zeolite on Ca is likely related to its affinity for calcium and its high capability for ion exchange (Mumpton and Fishman, 1977;Elliot et al, 1991).…”

“…Owing to the capacity for exchange of ions such as Ca and Mg and the absorption of these ions, the use of dietary zeolite in broilers increases blood calcium, affecting the involvement of Ca in bones (Ballard and Edwards, 1988). Some earlier studies have shown benefits in terms of increased concentration of serum Ca (Hussein et al, 1990;Roland et al, 1993) and bone ash (Elliot et al, 1991;Watkins and Southern, 1991;Rabon et al, 1995), whereas others have reported no such effect (Elliot and Edwards, 1991;Keshavarz and McCormick, 1991;Eleroğlu et al, 2011). However, in the present study, no beneficial effect was observed with regard to Ca, P, and Mg retention in the serum and bone of broiler chicks with respect to the feeding of a diet containing zeolite.…”

“…This would suggest that the Al is remaining intact; Al is being held by zeolite structure, and is therefore not available for absorption. Natural zeolite contains considerable Al (Eleroğlu et al, 2011;Wu et al, 2013), which differs in a range between 12 and 16% based on the location of the mine. Hence, a mode of action that cannot be discounted as having important influence is the effect of zeolites on Al metabolism in birds.…”

Protective Effect of Microporous Natural Clinoptilolite on Lead-Induced Learning and Memory Impairment in Rats

“…It has been demonstrated that clinoptilolite binds the essential micronutrients copper, zinc, cobalt, and manganese to only a very limited extent, and does not adsorb either of the amino acids nor any of the fat-soluble vitamins studied (33,34), and no significant alterations in the serum concentrations of vitamins A and E, and inorganic phosphorus, potassium, copper and zinc (27). b) On the other hand it seems that considerable amount of various key mineral elements such as calcium, titanium, cobalt, magnesium, aluminum, and especially zinc can be potentially extractable from clinoptilolite in the acidic condition of stomach gastric fluid which can lead to positive changes on memory performance (35).…”
