“…Other researchers have documented the negative effects of AFB1 on total tract retention of energy, mean nitrogen (N), and amino acids in poultry. [4][5][6][7] It seems that AFB1 alone has a harmful effect on the metabolization of nutrients, a harmful effect on the intestine, or both, resulting in increased loss of endogenous nutrients, reduced digestibility of nutrients, or both. 8 From the aforementioned studies, it is difficult to discern a dose-effect relationship between AFB1 and histological changes in the gastrointestinal tract (GIT).…”

This study investigated the effects of aflatoxin B1 (AFB1) and milk thistle seed (MTS) on some apparent ileal morphology and digestibility variables in the small intestines of broilers. A total of 216 Ross 308 male broiler chickens were allocated in a 3 3 factorial arrangement of the treatments with three concentration of AFB1 (0, 250, and 500 ppb) and three levels of MTS (0, 5, and 10 g kg -1 ). On day 35, the birds that received diets with 500 ppb of AFB1 alone (main effect) showed significant decrease in apparent ileal digestibility [dry matter (DM; 72.46±0.27) and ratio of VL to crypt depth (VL/CD; 4.74±0.07)] in their ileum segments (P<0.01). However, the mean nitrogen (N; 61.39±0.48) and crypt depth (CD; 173.5±9.87), in the ileum were significantly greater for the birds that were fed with 500 ppb AFB1 alone in their diets when compared with the control (P<0.01). Also, thistle seeds can ameliorate the toxic effects of AFB1 on some ileal digestibility factors, that is, DM, N, Ca, and CP, in broiler chicks. Nevertheless, ileum morphology of VW and goblet cell numbers were not affected negatively by the AFB1 plus MTS in diets. The results of this study indicated that the use of MTS independently reduced the toxic effects of AFB1, facilitated the absorption of nutrients, and reduced the metabolic demands of the intestinal tract in broiler chickens.

“…Hassan et al (2000) reported that the toxicity of AFB1 as characterized by reduction in body weight gain as interfere with normal metabolic pathway through the inhibition of protein synthesis and enzymes system that is involved in carbohydrate metabolism and energy release. Another point of view was discussed by (Nelson et al,1982), who postulated that aflatoxin reduce the ability of the bird to digest dry matter.…”

Key words:aflatoxin, broiler, adsorbent compounds, detoxificationThe objective of this study was to investigate the protective effect of dietary natural sorbent-Humate (0.2%) and Hydrated sodium calcium aluminosilicate (HSCAS) (0.5%) on the prevention of aflatoxin (AF) toxicity in the broiler chicken 7-35 days of age. Two hundred and forty broiler chicks were randomly divided into four treatment groups of 4 replicates (each contained 15 chicks). While chicks in group 1 were fed a basal diet free of toxin (control), group 2 chicks were fed a basal diet contaminated with 1ppm AF, the other two groups 3 and 4 were fed contaminated basal diet supplemented with 0.2% Biofarm® Dry humate, and 0.5% HSCAS, respectively. Parameters evaluated were growth performance, some serum constituents, some organs weight, and immune response to Newcastle disease and infectious bursal disease. The results showed that, Aflatoxin (1 ppm/kg) significantly reduced feed intake, weight gain and feed efficiency. Further aflatoxin increased the relative weights of liver, kidney, gizzard and spleen, while the relative weights of thymus and bursa of Fabricius were decreased by AF. Aflatoxin toxin also reduced antibody titres against Newcastle disease and infectious bursal disease. Modified 0.2% Humate significantly (P ≤ 0.05) improved body weight, feed intake, decreased relative organ weights and improved antibody titres, bursa of Fabricius and thymus weights. Hydrated sodium calcium aluminosilicate (0.5%) showed improvement against AF. The results of our experiment showed that 0.2% Humate and 0.5% HSCAS has a positive effect on the growth of broilers. And it could have been a suitable natural supplement for growing broilers against the adverse effects of aflatoxins.

“…In all birds inoculated with E. coli, nitrogen content of the excreta increased significantly, and gross energy content tended to increase. This same phenomenon has been associated with pale bird syndrome (Nelson et al, 1982) and coccidiosis in broilers (Sharma and Fernando, 1975) and with stunted bird syndrome in turkeys (Schmidt, 1983). Increases in the ether extract of excreta from stunted broilers have also been reported (Sharma and Fernando, 1975;Lilburn<?ia/., 1982).…”

Dietary Protein and Yolk Sac Inoculation with Escherichia coli in Young Turkeys

1985

An experiment was conducted to examine the effect of pathogenic Escherichia coli inoculated into the yolk sac of day-old turkeys. Escherichia coli was isolated from the yolk sac of stunted poults and inoculated directly into the yolk sac of day-old birds. Poults were administered either .1 ml of uninoculated sterile Todd-Hewitt broth or .1 ml of a 10(-3) or 10(-2) dilution of a 24-hr E. coli culture containing 3.4 X 10(8) viable bacteria/ml. In addition, poults were fed either 28 or 22% protein diets from 0 to 21 days of age to form a 3 X 2 factorial arrangement. Body weight gain and feed consumption were measured weekly, and dry matter and protein retention and nitrogen-corrected metabolizable energy were measured from 7 to 10 and 17 to 20 days postinoculation. Intestinal mucosal dipeptidase and maltase activities were determined at 21 days of age. Average mortality by 7 days of age was increased from 1 to 36% from the E. coli inoculation of the yolk sac. Escherichia coli significantly depressed body weight gain and feed consumption 27 and 30, 13 and 16, and 6 and 8%, respectively, during the first, second, and third weeks of the experiment but failed to affect feed efficiency. Feeding a 28% protein diet alleviated the depression in feed consumption and body weight gain to some extent compared with a substantial depression at 22% protein. Nitrogen content and gross energy of the excreta were increased by both dilutions of E. coli for the 7 to 10-day period; this was indicative of a malabsorption of nutrients.(ABSTRACT TRUNCATED AT 250 WORDS)
