“…Clinoptilolites have been reported to improve the performance of poultry (Nakaue et al, 1981;Willis et al, 1982;Waldroup et al, 1984;Olver, 1989). In the laying hen experiment reported in the present study, there was no improvement in performance with dietary supplementation with NZ.…”

Three experiments were conducted to investigate the effect of zeolites on laying hens (Experiments 1 and 2) and broiler chickens (Experiment 3). Each experiment used corn and soybean meal-based practical diets. Experiment 1 was a 90-day trial and used 200 40-wk-old laying hens. The basal diet contained 2.75% calcium and .7% total phosphorus. The dietary treatments were the basal diet and the basal diet plus 1.5% synthetic zeolite (SZ; Ethacal). Experiment 2 was a 56-day trial and used 360 36-wk-old laying hens. The dietary treatments were .12, .22, .32, and .42% nonphytin phosphorus with and without 1.0% SZ and 1.0% natural zeolite (NZ; Zar-Min). All diets contained 3.5% calcium. Experiment 3 utilized 240 broiler cockerels from 1 to 16 days. The dietary treatments were two calcium levels (.65 and 1.0%) with and without 1.0% supplementary SZ and NZ. In Experiment 1, egg specific gravity was significantly increased with SZ supplementation. Egg weight and egg production were unaffected. Phytin phosphorus retention and plasma dialyzable phosphorus were significantly reduced by SZ. In Experiment 2, egg specific gravity was not affected by SZ or NZ. Egg weight, egg production, plasma dialyzable phosphorus, and the retention of phosphorus and phytin phosphorus were significantly reduced by SZ with the effect on egg weight and egg production being the most severe at the lower levels of dietary nonphytin phosphorus. Natural zeolite had no effect on egg weight, egg production, plasma calcium, plasma phosphorus, or on the retention of calcium, phosphorus, and phytin phosphorus. In Experiment 3, weight gain and percentage tibia bone ash were significantly reduced by SZ. The SZ had no effect on the incidence and severity of tibial dyschondroplasia. Weight gain, feed efficiency, and the incidence and severity of tibial dyschondroplasia were significantly reduced and the percentage bone ash significantly increased by 1.0% calcium. Natural zeolite significantly improved feed efficiency and had no effect on any other parameter measured.

“…Zeolites are crystalline, hydrated aluminotectosilicates of alkali and alkaline-earth cations, having infinite, three-dimensional structures of interconnecting channels and great pores, capable of trapping molecules in suitable conditions (Mumpton and Fishman, 1977;Mumpton, 1999). Also, the beneficial effects of zeolite may be attributed to the aluminum, silicon, or sodium content of zeolites, because it has been established that these minerals can influence calcium -metabolism, thus improving calcium (Ca) and phosphorus (P) utilization (Waldroup et al, 1984;Leach et al, 1990;Elliot and Edwards, 1991;Watkins andSouthern, 1991 andShariatmadahari, 2008). Studies have revealed that the zeolite (clinoptilolite) is able to adsorb damaging toxins that can reduce the growth of animals (Oğuz and Kurtoğlu, 2000), affects gut morphology, decreases pH and lowers pathogenic bacteria counts, which suggests that intestinal health can be enhanced by its use (Khambualai et al, 119 2009 andWu et al, 2013).…”

This work was aimed to study the effect of zeolite (Clinoptiolite) addition on productive performance and blood constituents of broiler chickens drank saline well water (3398 ppm total dissolved solids, TDS). A total number of 120 broiler chicks one dayold unsexed Ross 308 (body weight of 40.09 g ± 0.11). Chicks were randomly separated to four equal treatments (30 chicks of each) which in turn separated to three equal replicates (10 chicks each). The 1 st treatment (T1), chicks drank tap water containing 265 ppm TDS with basal diet. The 2 nd treatment (T2), chicks drank saline well water containing 3398 ppm TDS with basal diet. The 3 rd treatment (T3) and the 4 th treatment (T4) chicks drank saline well water containing 3398 ppm TDS with basal diet + 3 % zeolite and + 6 % zeolite, respectively. Final body weight, total weight gain and feed conversion of broiler chickens were significantly enhanced in control group (T1), T3 and T4 as compared with the chickens in T2. On the other hand, the total feed intake significantly decreased in the chickens of T4 as compared with T1 and T2, while, the total water intake significantly increased in T2 compared with other treatments. Carcass weight percentage was significantly increased in the chickens of T1, T3 and T4 treatments as compared to T2. Red blood cells, hemoglobin and packed cell volume were increased (P<0.05) in the chickens of T3 when compared to T2. Albumin level was significantly increased in T4 compared with other treatments. Creatinine, Alanine and aspartic transaminase concentrations were increased (P<0.05) in the chickens drank saline well water (T2) as compared to other treatments. On the other hand, glucose and cholesterol levels significantly decreased in the chickens of T2 as compared to T1, T3 and T4. In conclusion, adding 3 % zeolite in broiler chickens diets might enhance the productive performance and some hemato-biochemical parameters under drinking saline well water conditions.

“…Among many properties attributed to zeolites, most typically related to their effectiveness in animal nutrition is their ability to selectively exchange a variety of cations without much major changes in their structure (Waldroup et al, 1984;Elliot and Edwards, 1991;Shariatmadari, 2008). Beneficial effects may also be attributed to the silicon (Si), aluminum (Al) or sodium (Na) content of zeolites because it has been established that these minerals can influence calcium (Ca)-metabolism, thus improving Ca and phosphorus (P) utilisation (Leach et al, 1990;Watkins and Southern, 1991).…”

Natural zeolite, or sodium aluminosilicate, influences calcium (Ca) and phosphorus (P) utilisation in chicks. A 2×2 factorial arrangement of treatments was used to investigate the effect of dietary Ca (recommended and below recommended levels) and zeolite (0 and 0.8%) on growth, plasma, tibia and faeces in chickens from 1 to 42 days of age. Zeolite supplementation did not affect overall body weight (BW) gain, feed intake (FI) or feed conversion ratio (FCR) of broiler chickens (P>0.05). Overall mortality of zeolite-fed chickens was lower than in untreated ones (P<0.01). Reduction of dietary Ca of approximately 10 to 18% decreased (P<0.05) BW at 14 and 42 days of age in association with reduced FI, but overall FCR was unchanged. Serum protein and sodium constituents were reduced in birds fed zeolite (P<0.05). Decreasing dietary Ca level increased (P<0.01) serum, total protein and glucose concentrations, but decreased Ca level. Zeolite decreased bone ash in birds fed a Ca-deficient diet while increased faecal excretion of ash, Ca, P and aluminum. However, zeolite increased tibia weight (P<0.05) and thickness (P<0.01). No significant response (P>0.05) in relative weight and gross lesion scores of liver or footpad lesion scores was found related to changes in dietary regimens.The results of the present study do not corroborate the hypothesis that the effectiveness of zeolite may be improved in Ca-deficient diets in association with its ion exchange capability.
