“…Katsoulos et al [1] reported that cow fed with ration containing 2.5% clinoptilolite had significantly fewer cases of clinical ketosis during the first week after calving and a higher milk yield. The benefit of clinoptilolite addition to ration on health and performance of weaned, growing, and finishing pigs was studied by Papaioannou et al [2].…”

“…The effects of zeolite supplementation on hematology and serum biochemistry of dairy cows, sheep, and sows have been studied by many workers [1,[3][4][5][6][7][8]. In addition, there are few existing studies concerning the effects of clinoptilolite supplementation on performance, wool growth, decreased ruminal ammonia concentration, and improved feed and bacterial protein flow to the small intestine [9][10][11].…”

The effects of feeding clinoptilolite on hematology, performance, and health of newborn Balouchi lambs were evaluated in this experiment. In a completely randomized design, 30 newborn lambs were allocated to three groups and fed by basal diet (C0; without clinoptilolite) and C1 and C2 (the basal diet plus 1.5% and 3% clinoptilolite, respectively, for 6 weeks (3 weeks before and 3 weeks after weaning)). Blood samples were taken from all lambs, at the time when the animals were allocated to the experimental diet and at the end of each week of experiment, and analyzed for hematology, plasma fibrinogen, and total protein. Performance and health of all lambs were measured. Fecal consistency score and diarrhea severity were evaluated. There was no difference between lambs in case of hematological parameters. Lambs fecal consistency score and severity of diarrhea were lowest (P < 0.05) for lambs on C1 and C2 and highest for lambs on C0. Dry matter intake and feed conservation ratio were similar between the groups of lambs fed by different diets, but daily gain of lambs differed significantly (P < 0.05) and was higher in C2. It was concluded that addition of 3% clinoptilolite to starter diet of newborn lamb can reduce incidence and severity of diarrhea, although its effect on hematology and performance was negligible.

“…In recent years there is an increased interest for using clinoptilolite, a natural zeolite, as feed additive in dairy rations during the transition period due to its beneficial effects on the incidence of metabolic disorders (Katsoulos et al 2005a(Katsoulos et al , 2006) and on the immune response after vaccination against E. coli (Karatzia 2010). Because of its high cation exchange capacity, clinoptilolite may interfere with trace elements in the gastrointestinal tract and impair their absorption.…”

Selenium (Se), copper (Cu), and zinc (Zn) play important antioxidant role during the transition period of dairy cattle. However, there is limited information about their blood fluctuations during the entire transition period, especially in heifers. Furthermore, it is questionable whether the use of clinoptilolite, a natural zeolite, affects the availability of these trace elements during this period. The objective of the present study was to monitor the blood concentrations of Se, Cu, and Zn during the transition period of dairy heifers and to investigate whether the dietary inclusion of clinoptilolite has any effect on them. Forty clinically healthy Holstein heifers were used in the experiment. They were randomly allocated in two equal groups (n = 20) formed according to their body condition score. The control group was fed only the basal ration whereas the daily feed of treatment group was supplemented with 200 g clinoptilolite. The experiment started 28 days before the expected day of calving and lasted until day 21 after parturition. Blood samples were taken at the onset of the experiment and then at weekly intervals until parturition, at the day of calving, and on days 7, 14, and 21. All samples were analyzed for blood Se and plasma Cu and Zn concentrations. The results indicate that the levels of Se, Cu, and Zn in blood change significantly (P < 0.05) throughout the transition period in dairy heifers and increase significantly (P < 0.05) immediately after calving. Furthermore, the dietary administration of clinoptilolite does not significantly affect their blood concentration (P > 0.05). Blood levels of Se, Cu, and Zn, although undergoing significant changes throughout the transition period in dairy heifers, remain practically stable until parturition and increase significantly immediately after calving. Clinoptilolite does not impair the dietary availability of the trace elements evaluated when added in heifers' rations during this period.

“…Many researchers have shown that the dietary inclusion of zeolites improves the average daily gain or feed conversion ratio in sheep, pig and dairy cows (Forouzani et al, 2004;Papaioannou et al, 2004;Katsoulos et al, 2006). Zeolites also enhance the reproductive performance of sows (Papaioannou et al, 2002), negatively affect the spermatozoon morphology of male rats (Taş et al, 2007), increase the milk yield of dairy cows (Katsoulos et al, 2006).…”

The objective of this study was to test the effects of dietary natural zeolite (clinoptilolite) on performance, skin and liver histology in rats. In this study, 24 10-week-old, weaned, adult male Spraque-Dawley rats with approximately 306  18.93 g initial live weight were used. The rats were randomly divided into four groups with three replicates, including a control group and groups with one of three doses of clinoptilolite (2%, 4%, and 6%) in their diets. All the rats were fed these concentrates throughout the experimental period of 56 days. The animals were reared individually in stainless steel cages. There were no significant differences in the primary and secondary follicle numbers among groups, but the diameters of each follicle were found to be significant. The primary and secondary follicle numbers and diameters ranged from lowest to highest as follows: 2.00-2. 33, 4.50-7.17; and 11.53-20.42, 57.63-102.12m, respectively. The differences occurred between the control group and group IV (containing 6% zeolite). In addition, the skin and liver histology results showed that there were no differences among the groups. Bu araştırma rat yemlerine ilave edilen doğal zeolitin (klinoptilolit) performans, deri ve karaciğer histolojisi üzerine etkilerini incelemek amacıyla yapılmıştır. Bu çalışmada, hayvan materyali olarak 24 adet on haftalık yaştaki, yaklaşık 306  18,93 g canlı ağırlığındaki sütten kesilmiş erkek yetişkin Spraque-Dawley rat kullanılmıştır. Ratlar tesadüf parselleri deneme desenine göre üçer tekerrürlü, 4 gruba (klinoptilolit içermeyen grup kontrol grubunu oluştururken, %2, %4, and %6 düzeylerinde klinoptilolit ilavesinin yapıldığı gruplar muamele gruplarını oluşturacak şekilde) rastgele dağıtılmıştır. Deneme 56 gün sürmüştür. Deneme bireysel paslanmaz çelikten yapılmış kafeslerde yürütülmüştür. Primer ve sekonder folikül sayıları bakımından gruplar arasında istatistiki olarak önemli düzeyde farklılık tespit edilmemekle beraber, her iki folikülün çap değerleri ise önemli bulunmuştur. Primer ve sekonder folikül sayıları ve çapları en yüksek ve en düşük değerler olarak sırasıyla 2, 00-2,33; 4,50-7,17 ve 11,53-20,42; 57,63-102,12m, olarak tespit edilmiştir. Önemli düzeydeki farklılık control grubuyla, IV. grup (%6 klinoptilolit içeren) arasında meydana gelmiştir. Ayrıca, derinin ve karaciğerin histolojik olarak incelenmesi sonucunda gruplar arasında önemli düzeyde farklılık tespit edilmemiştir.
