The effect of organic acid, zeolite, or their combination on performance, some serum indices, and ileum pH values in broilers fed with different phosphorus levels

ABSTRACT. Aim of the study was to investigate effects of different levels of perlite on intestinal morphometry in broilers (Ross 308). A hundred and eighty broiler cockerels were randomly allocated into three experimental groups (3 replications and 20 broilers per pen) and fed experimental diets supplemented with different levels of perlite (0%, 2%, 4%). At 21, 28, 35 and 42 days of the study, 2 broilers were randomly selected from each replication, slaughtered and various sections of small intestine (1, 10, 30, 50, 70 and 90% of small intestine length) sampled for morphometry characteristics. Villi height, crypts depth and villus height / crypt depth ratio were measured microscopically. According to the results, a significant difference was observed on small intestine morphology post-perlite supplementation in experimental groups compared to control group. Supplementation of diet with perlite (2%) significantly increased average villi height in various sections of small intestine (1, 70 and 90%) in experimental birds on days 28 and 35 (P < 0.05). In addition, similar findings were observed after addition of perlite (4%) on villi height on day 42 (P < 0.05). Furthermore, on day 28, average villi height and depth of liberkuhn crypts in small intestine (10%) differed significantly in cockerels fed diets containing 2% perlite in comparison to controls (P < 0.05). These results suggest that supplementation of perlite in broilers' diet can improve intestinal morphometry.

The present study was designed to determine the efficacy of a novel multicomponent mycotoxin detoxifying agent (MMDA) containing modified zeolite (Clinoptilolite), Bacillus subtilis, B. licheniformis, Saccharomyces cerevisiae cell walls and silymarin against the deleterious effects of Aflatoxin B1 (AFB1) and Ochratoxin A (OTA) in broiler chicks. A total of 160 one-day-old Ross 308® broiler chicks were randomly allocated in four treatment groups, with four replicates, according to the following experimental design for 42 days. Group A received a basal diet; Group B received a basal diet contaminated with AFB1 and OTA at 0.1 mg/kg and 1 mg/kg, respectively; Group C received a basal diet contaminated with AFB1 and OTA and MMDA at 1 g/kg feed, and Group D received a basal diet contaminated with AFB1 and OTA and MMDA at 3 g/kg feed. Results showed that ingested mycotoxins led to significant (p ≤ 0.05) reduction in body weight and feed conversion from 25 days of age, induced histopathological changes, increased the pH of the intestinal content, and altered the biochemical profile of birds with significantly (p ≤ 0.05) increased aspartate aminotransferase (AST) values (p ≤ 0.05). On the other hand, the supplementation of MMDA significantly (p ≤ 0.05) improved the feed conversion ratio (FCR) during the second part of the study, diminished biochemical alterations, reduced pH in jejunal and ileal content, and E. coli counts in the caeca of birds (p ≤ 0.05). It may be concluded that the dietary supplementation of the MMDA partially ameliorated the adverse effects of AFB1 and OTA in broilers and could be an efficient tool in a mycotoxin control program.
