“…1, where differences among treatments are slight and hence are not observable. These results are similar to those reported by Wu et al (2013) who evaluated the effect of dietary supplementation with 2% natural and modified clinoptilolite on broiler performance, as well as the results reported by Öztürk et al (1998) who found something similar in an experiment where they fed a diet supplemented with a natural zeolite to laying hens.…”

The objective of this study was to evaluate the effects of the addition of zeolite on the feeding of Cobb 500 chickens in the productive parameters. The work was carried out in an integral farm of Ecuador, adopting the standards of biosafety and animal welfare for the breeding of poultry; no vaccines or drugs were administered. 200 chickens (1-day old) were studied for 42 days and distributed in 5 treatments, each one with 4 replicates (10 chickens per replicate, randomly selected); the treatments were: T1(control), T2(zeolite 2%), T3(zeolite 3%), T4(zeolite 4%) and T5(zeolite 5%). All of the groups were fed with BALMAR, a commercial feed (Pre-initial: 22.56% CP, 3150 Kcal/kg ME; initial: 21% CP, 3200 Kcal/kg ME; grow-out: 19.5% CP, 3250 Kcal/Kg ME), T1 included a commercial toxin trapper, for all other groups zeolite was added as a substitute for the commercial toxin trap. The variables studied were: feed and water consumption, feed conversion ratio, live weight and mortality. The data were processed with the statistical program Stat graphics Centurion XV.I, by means of ANOVA analysis. The results of this experiment showed that there were no significant statistical differences in water consumption, food intake and feed conversion when comparing the treatments with the control, although, the final weight showed statistical difference (p<0.05). The highest mortality was recorded in T1 (12.5%). It is concluded that at higher zeolite increase, better effects, thus the live weight of T5 (1638.9±46.7) was statistically similar to the control (1734.3±49.3); water and feed consumption and feed conversion rate were not affected; possibly the reduction in mortality was due to the toxins trapping action of zeolite.

“…Zeolite has a beneficial effect on feed components owing to the fact that they improve energy and protein retention. Zeolite influences nutrient absorption in the digestive tract allowing for better results than other supplements (Wu et al, 2013a). Zeolite as a dietary supplement in poultry showed that animals mostly grow faster, and the number and severity of intestinal diseases are reduced (Pavelic et al, 2001).…”

“…Zeolite has a unique structure, which is similar to that of a honeycomb, and each tiny cavity within every piece of zeolite is negatively charged. This allows for positively charged molecules to be pulled in and trapped in their pores (Wu et al, 2013b, Wu et al, 2013a. Due to their biologically neutral structure and their unusual properties, zeolites have been applied to veterinary medicine, agriculture, industry, sanitation and environmental protection (Pavelic et al, 2001).…”

Digestive enzyme, histology, small intestine, zeolite.Submitted: 10/August/2016 Approved: 27/February/2017 ABSTRACT Many kinds of feed additives can be used in chicken diets to stimulate intestinal morphological maturation and, consequently, intestinal function. The purpose of this study was to evaluate the effect of zeolite on broiler performance, gut morphology and gut digestive enzyme activity. The one-day old broiler chickens Ross 308 were assigned randomly into 3 groups with 30 birds per treatment. The 3 dietary treatments were: basal diet only (control group), basal diet + 2% zeolite, basal diet + 3% zeolite. Morphological and morphometric intestinal assessments were conducted using a light microscope. There was observed increase in villus height, villus perimeter, villus section area and crypt depth throughout duodenum and mid jejunum of the broilers fed zeolite. Supplementation especially with 2% zeolite was associated with greater villus heights, villus perimeter, villus section area and crypt depth in duodenum and ileum mucosa compared to the controls. The diet with 2% zeolite also contributed to significant increase proventriculus (pepsin) and pancreas (trypsin, lipase) activity compared to the controls The results suggest that dietary supplementation of zeolite increased feed consumption, intestinal morphology parameters and enzyme activity of gastrointestinal tract in broiler which improved growth performance.

“…In regard of the pH of the content from each compartment of the gastrointestinal tract, one bird at time per plot in fasting, was weighted and slaughtered by cervical dislocation, in a total of 10 individuals for pH analysis. All the procedures to obtain the pH of the content of every compartment of the gastrointestinal tract was conferring as suggested by Wu et al (2013). Immediately after the slaughter of the birds, the viscera was exposed, so the organs necessary to the analysis could be identified: goiter, proventriculus, gizzard, duodenum, jejunum, ileum, cecum and colon.…”
