“…The level of 0.5% clinoptilolite, in growing and finishing pigs diets did not affect feed intake, daily weight gain, feed conversion, carcass quality, hot carcass weight, back-fat thickness, loin depth and lean percentage, compared to a diet without addition of zeolites (ZIMMERMANN, 2014). The same result was reported by ISLAM et al (2014), where the use of 0.5% artificial zeolites had no effect on growth performance and carcass quality. In contrast, ALEXOPOULOS et al (2007) reported that weight and feed conversion increased using 2% clinoptilolite in growing and finishing pigs.…”

“…The inclusion of 0.5% clinoptilolite in growing and finishing pig diets reduced the ammonia concentration (ppm) within the facility with a slatted floor. This was shown by ISLAM et al (2014), who reported that the use of 0.5% artificial zeolite in the diet of pigs led to a significant reduction in the emission of ammonia, sulfur dioxide and hydrogen sulfide from feces. Likewise, BUJŇÁK et al (2015), using 2% zeolite in the diet of growing pigs, obtained similar results, where the addition of zeolites showed a tendency to increase the ammonia content in feces, decreasing their volatilization to the environment.…”

“…The properties of zeolites allow the retention of nitrogen and confer the ability Schneider et al to improve the efficiency in the digestion of proteins (SHURSON et al, 1984;MUMPTON, 1999;LEUNG et al, 2007). New studies also related zeolites to the preservation of the environment due to their capacity to retain pollutants of animal production, especially ammonia (LEUNG et al, 2007;ISLAM et al, 2014;ZIMMERMANN, 2014;BUJŇÁK et al, 2015).…”

Zeolites are minerals that have intriguing properties such as water absorption, ion adsorption and cation exchange capacity. There are approximately 80 species of natural zeolites recognized and hundreds of artificial zeolites, which have been researched in several fields. Due to their chemical characteristics, zeolites have great potential for use in animal production, especially in poultry and swine farms, as food additives, litter amendment and treatment of residues, with direct and indirect effects on performance, yield and quality of carcass, ambience of farm sheds and reduction of environmental pollution.

“…The natural zeolite supplement did not affect growth rate of weaned pigs, but alleviated experimentally induced diarrhea (66). Similarly, the AZ-fed pigs didn't show differences in weight gain and feed conversion ratio, but their serum IgG levels were increased and they had reduced E. coli count (65). An early study of McCollum and Galyean (67) in the steers showed no effect of CPL on growth performance and feed efficiency.…”

Zeolite clinoptilolite nanoporous feed additive for animals of veterinary importance: potentials and limitations

et al. 2017

I n the past two decades many substances of natural or synthetic origin were studied as potential alternatives to antibiotic growth promoters (AGP) and some of them, particularly immunomodulators (IMs) and nutraceuticals (NCs), have shown to be capable of stimulating functions of the immune system and improving general health. At the same time, they were shown to be harmless for animals and the environment. Promising results have been obtained with natural clay minerals, zeolites among which clinoptilolite (CPL) is the best known as zootechnical and biomedical feed ingredient widely reported in scientific literature and used in farm animal nutrition. CPL has a potential to replace AGP due to its unique anti-bacterial properties, safety and efficacy as dietary supplement in food animals unifying potentials of an IM and NC. Currently, there INTRODUCTIONT he phrase "survival of the fittest" as an alternative to "natural selection" has been adopted and published in 1868 by Charles Darwin (1), and nowadays is becoming so true because of the rapid emergence of antibiotic resistant strains of pathogenic microbes of biomedical, particularly veterinary importance. This is a consequence of non-clinical use and misuse of dietary antibiotics for more than sixty years to prevent bacterial infections and to enhance performance in livestock production, mostly in chickens and pigs (2). Namely, the increased sanitary problems in intensive farming of food animals have been overcome thus far by adding sub-therapeutic doses of antibiotic growth promoters (AGP) infeed to enhance production efficiency by increasing growth rate, improv- ing feed utilization and reducing mortality from clinical disease is well documented particularly in swine production systems (3). However, the consumers especially in developed countries are becoming increasingly concerned about drug residues in meat and other animal products (4). In addition, it has been suggested that the continuous use of antibiotics may contribute to a reservoir of drugresistant bacteria (5) which may be capable of transferring their resistance to pathogenic bacteria in both animals and humans (6). As a result, many countries have banned or are banning the inclusion of antibiotics in diets as a routine means of growth promotion. The first experience of an AGP ban in Sweden in 1986 indicated a reduction in growth and an increase in morbidity and mortality rates in weaned pigs, which emphasized the importance of antibiotic use in intensive swine production(7). The total ban of dietary AGP in the EU countries since January 1, 2006 (EU Regulation No. 1831 and the elimination of their use in animal feed and water in the USA effective January 1, 2017 (FDA, CVM 2012, VFD Basics 2017) has had a serious influence on both health and performance of food animals underlining the need to develop alternative dietary and non-dietary strategies to evaluate the potential antimicrobial agents for their replacement (8). According to the World Health Organization, most antibiotics will not ...

“…In the past two decades intensive efforts have been focused on the development of alternatives to AGP to maintain swine health and performance. Many research papers and excellent reviews have been published on this subject, describing immunomodulators of natural (Gallois and Oswald 2008;Gallois et al 2009) and synthetic origin (Valpotic et al 2013;Valpotic et al 2014), probiotics (Cho et al 2011), prebiotics (Halas and Nochta 2012) as well as less traditional alternatives such as selected organic acids, amino acids, protein sources, plant extracts (Lalles et al 2009), peptides, clay minerals, egg yolk antibodies, essential oils, fatty acids, rare earth elements (Thacker 2013) and naturally extracted clay smectite or artificially composed zeolite with antibacterial activities in the gut (Almeida et al 2013;Islam et al 2014). However, only a small number of these have been shown to be effective.…”

ABSTRACT:The ban on dietary antibiotic growth promoters (AGP) in swine production has focused increasing research efforts on the development of alternative feed supplements. One such alternative to AGP is the dietary zeolite clinoptilolite (CPL). The aims of this study were to evaluate, in weaned pigs, the effects of CPL on: (a) growth performance, (b) gut health (reduction of harmful bacteria and, incidence/severity of diarrhoea) and (c) circulating or ileal mucosal subsets of lymphoid immune cells, over the course of five weeks post weaning. The non-treated pigs received standard Phase 1 diet from Day 0 to 21 and Phase 2 diet from Day 22 to 35, whereas both diets of experimental pigs were supplemented with 0.5% CPL. The pigs receiving diet supplemented with CPL had significantly higher average daily gain at Day 28 but significantly lower daily gain at Day 35 of the experiment (P < 0.05). The CPL group exhibited non-significantly improved feed conversion ratio (1.83 vs. 2.17) for the total duration of the experiment (Day 0 to Day 35). Although shedding of haemolytic/enterotoxigenic E. coli was more frequent in the CPL group, the sum of their diarrhoea severity score was 12.96% lower (47 vs 54) than that of the non-treated controls. The proportions of circulating lymphoid cell subsets tested (CD45 + , CD4 + , CD21 + ), were significantly (P < 0.05 to P < 0.01) higher in CPL-treated pigs between Day 21 and Day 35 of the experiment. Immunohistology/ morphometry of ileal segments revealed an increased recruitment of CD45RA + cells in interfollicular (P < 0.05),but not in follicular areas of ileal PP of CPL-treated pigs at Day 35. In conclusion, CPL did not improve growth in weaned pigs, and generally it failed to improve their feed conversion efficiency. Further, it did not suppress faecal shedding of enterotoxigenic E. coli; however, it was shown to be effective as an immunomodulatory agent by promoting the recruitment of circulating and intestinal immune cell subsets.
