“…It is assumed that clay minerals reduce the speed of feed passage along the intestines, which results in better nutrient conversion and higher water resorption (Castro and Elias, 1978;Papaioannou et al, 2005). Whilst Poulsen and Oksbjerg (1995) did not observe any changes in protein retention using a diet supplemented of with 3% of zeolite, other studies have reported improved digestibility of nutrients (Castro and Elias, 1978;Kyriakis et al, 2002;Chen et al, 2005;Ly et al, 2007), and protein and energy retention (Ly et al, 1996(Ly et al, , 2007Parisini et al, 1999). Some authors put the improvement in protein and energy retention down to the increased activity of pancreatic enzymes due to the supplementation of diets with clay minerals.…”

“…Some authors put the improvement in protein and energy retention down to the increased activity of pancreatic enzymes due to the supplementation of diets with clay minerals. Pancreatic enzymes bind to the surface of the adsorbents and form complexes that are active within a wide pH range in the digestive tract (Cabezas et al, 1991;Parisini et al, 1999;Papaioannou 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.

“…In general, the growth promoting effect of Cp and other zeolites or clays with more or less common physicochemical properties are attributed to a number of mechanisms which involve the binding and/ or removal of noxious compounds derived through microbial activity (i.e. ammonia and p-cresol), the retardation of digesta passage rate through the intestines and the favoring of feed components hydrolysis through an enzyme activity enhancement (Shurson et al, 1984;Pond et al, 1988;Cabezas et al, 1991;Olver, 1997;Parisini et al, 1999).…”

Experimental study on the effect of in-feed administration of a clinoptilolite-rich tuff on certain biochemical and hematological parameters of growing and fattening pigs

The effect of the long-term dietary use of a clinoptilolite-rich tuff (Cp) on certain biochemical and hematological parameters was studied in pigs. Forty-eight healthy piglets (24 females and 24 males) were used in the study, equally allocated in two experimental groups, depending on the inclusion or not of Cp in their feed (Cp+ and Cp− groups respectively). Cp was incorporated in their feed at the inclusion rate of 2% and was administered continuously from weaning to slaughter. All pigs were individually weighed upon commencement of the study [25(± 3) days of age] and subsequently at the end of the weaning, growing and fattening stages [70(± 3), 112(± 3) and 161(± 3) days of age, respectively] and blood sample collections were performed for analyses. Cp ingestion was well tolerated and resulted in a higher body weight gain during the weaning stage, as well as during the whole monitoring period (P b 0.05). The diet had no effect on serum K, Na, Ca, P, total protein, albumin and total bilirubin concentrations throughout the study (P N 0.05). Furthermore, no significant alteration was noticed concerning the hematocrit, leucocyte count and hemoglobin concentration (P N 0.05). Conversely, the dietary inclusion of Cp resulted in a lower serum urea-N and cholesterol concentrations in all blood samplings apart from the initial one (P b 0.05). Likewise, Cp+ group demonstrated an elevated serum glucose concentration at the blood samplings performed on 112(± 3) and 161(± 3) days of age and a lower AST activity at the latter (P b 0.05). In the context of this study, the long-term dietary use of Cp at the inclusion rate of 2% appeared to enhance the performance of growing and fattening pigs without adversely affecting their health status in terms of undesirable changes of their biochemical and hematological profiles.

“…This results in an increase in parameters related to animal growth and in an improvement of meat and derived final product quality. Currently, sepiolite is used widely as a feed additive supplied to broiler chickens (7) and pigs (8), among other types of livestock. Furthermore, sepiolite has also been proposed as a remediation agent for contaminated soil (9).…”

The Animal Food Supplement Sepiolite Promotes a Direct Horizontal Transfer of Antibiotic Resistance Plasmids between Bacterial Species

Animal fodder is routinely complemented with antibiotics together with other food supplements to improve growth. For instance, sepiolite is currently used as a dietary coadjuvant in animal feed, as it increases animal growth parameters and improves meat and derived final product quality. This type of food additive has so far been considered innocuous for the development and spread of antibiotic resistance. In this study, we demonstrate that sepiolite promotes the direct horizontal transfer of antibiotic resistance plasmids between bacterial species. The conditions needed for plasmid transfer (sepiolite and friction forces) occur in the digestive tracts of farm animals, which routinely receive sepiolite as a food additive. Furthermore, this effect may be aggravated by the use of antibiotics supplied as growth promoters.
