“…Rabbits' diet contains low levels of crude protein comparing to other non-ruminant species due to the particularity of the rabbits' digestive system (caecotrophy, formation of caecotropes). It seems that the crude protein level used in this study (17%) led to less pronounced response to dietary NZ and this is in agreement to the findings reported in studies with lambs (Pond et al, 1984;Pond, 1989) or swine (Poulsen & Oksbierg, 1995;Papaioannou et al, 2004).…”

“…Clinoptilolite is the most abundant zeolite in nature and also the most widely used in studies involving farm animals. For example, the results of those studies suggest that the use of clinoptilolite in the diet of growing lambs have favourable effects on their growth and performance (Deligiannis et al, 2005), whereas similar effects were observed in other studies with ruminants (Mumpton & Fishman, 1977;Pond et al, 1984;Pond, 1989;Katsoulos et al, 2005), as well as non-ruminant (monogastric) animals (Papaioannou et al, 2004) or poultry (TserveniGousi et al, 1997;Christaki et al, 2001). However, to our knowledge, there is no evidence in the literature of similar studies in rabbits.…”

The objective of this study was to assess the effect of a diet containing a clinoptilolite rich material (tuff) on growth and carcass characteristics of fattening rabbits. Three diets were formulated; diet C was a standard commercial diet that served as control, while diet L contained 1.25% natural zeolite (NZ) and diet Η contained 2.5% NZ. Seventy-two New Zealand χ Californian rabbits were used after weaning at 35 days of age. They were randomly allocated into three groups (n=24, with three replicates of four male and four female rabbits each, balanced for body weight) according to the above dietary treatments. All rabbits were weighed individually on weaning and thereafter on weekly basis. Feed intake was monitored weekly on subgroup basis. The experiment lasted 8 weeks. Performance traits and mortality level were recorded in the aforementioned period. In the end of this period all rabbits were stunned and slaughtered to obtain the European carcass weight. Six carcasses per group (two per subgroup, one male and one female) were randomly selected for the determination of carcass characteristics. The results of the current study showed that the incorporation of a clinoptilolite rich tuff (natural zeolite) in the diet of growing rabbits did not affect their growth or the carcass characteristics, whereas feed efficiency and mortality level were negatively affected.

“…The structure and physical-chemical characteristics of these clay minerals and kaolin, which is a phyllosilicate mineral, are similar . A significant increase in the body weight gain and improved conversion of feed containing clay minerals has been shown by numerous studies (Pond et al, 1981(Pond et al, , 1988Vrzgula et al, 1982;Bartko et al, 1983;Pond and Yen, 1987;Castro and Iglesias, 1989;Cabezas et al, 1991;Papaioannou et al, 2004;Chen et al, 2005;Kolacz et al, 2005;Papaioannou et al, 2005;Alexopoulos et al, 2007;Prvulovic et al, 2007). Naturally, their effect on the efficiency of animals is associated with the type, physicochemical and structural qualities, purity and proportion of these minerals in the diet (Pond and Yen, 1987;Pond et al, 1988;Papaioannou et al, 2004Papaioannou et al, , 2005, and by the age of animals (Papaioannou et al, 2004;Alexopoulos et al, 2007).…”

“…The inactivation of diarrhoea-causing enterotoxins by hydrogen bond implicated interactions with the surface of the layered crystalline structure of mineral clays or with their between-layer space (Brouillard and Rateau, 1989;Papaioannou et al, 2004) markedly reduces the duration and severity of diarrhoea (Castro and Elias, 1978;Bartko et al, 1983;Papaioannou et al, 2004). Brouillard and Rateau (1989) and Ramu et al (1997) confirmed a high adsorption ability of clay adsorbents to act against E. coli enterotoxins under in vivo conditions.…”

“…The amelioration in the clinical manifestations of diarrhoeal diseases can also be explained by the elimination of various factors that are associated with the occurrence of these diseases, e.g., in piglets, primarily at the period of weaning. These factors include intestinal hypersensitivity to feed antigens or weaning-induced changes leading to the manifestation of malabsorption syndrome caused by a reduction in the digestive enzyme activity; both can predispose to infectious enteritis (Wilson et al, 1989;Papaioannou, et al, 2004Papaioannou, et al, , 2005.…”

ABSTRACT:The purpose of the present study was to assess the effect of kaolin feeding on health status, body weight gain (BWG), course of diarrhoeal infections caused by enterotoxigenic strains of Escherichia coli (ETEC) and the level of mycobacterial contamination in weaned piglets. The testing was performed in two experiments involving 40 weaned piglets at the age of 28 days. In the infection-free experiment, piglets were fed a diet without (C0) or with 1% content of kaolin (K0) for 20 days. Subsequently, all of them were fed the same diet without kaolin supplementation for 39 days. Identical diets were fed during the infection experiment, and moreover, both groups (CI and KI) were orally infected with ETEC (O141:F18ac, STa+) on Day 1 of experiment. The short-term feeding of kaolin to weaned piglets had a significant positive effect on their BWG. During the period of feeding the kaolin-containing diets, BWG in C0 and K0 were 0.20 and 0.29 kg, respectively (P < 0.05), and in CI and KI 0.13 and 0.19 kg, respectively (P < 0.05). There was no evidence of side effects to their health, neither was there any change in biochemical and haematological profiles. In the infection experiment, a protective effect of kaolin on the course of ETEC infection was evident. Colonization and shedding of ETEC by piglets fed the kaolin diet were milder and had a shorter duration in comparison with control piglets. The culture examination of pure kaolin and kaolin containing diets for mycobacteria were negative. Potentially pathogenic mycobacteria occurring in the environment were isolated from faeces and tissues of pigs. According to these results, supplementation of diets with 1% kaolin to prevent diarrhoea in piglets and to support their growth in the critical post-weaning period could be recommended.

A statistically significant difference was determined in clinoptilolite and kaolin group, when they are separately compared with the control group in respect of the effect on MAP, HCO3 (-), lactate, base excess, haemostasis duration and survival rates. The effect of clinoptilolite on haemostasis and survival time was observed to be at least as good as that of kaolin; therefore, clinoptilolite can be used as an active ingredient in a topical haemostat.
