Effects of feeding aFusarium poae extract and a natural zeolite to broiler chickens

Abstract

A feeding trial was conducted in order to determine the effects of aFusarium poae extract on the health and performances of broiler chickens and the possible protective effect of a natural zeolite. TheF. poae extract contained nivalenol, T-2 toxin and diacetoxyscirpenol and demonstrated high toxicity when administeredi.p. to rats. One-day-old broiler chickens were fedad libitum over a period of 28 days with the following diets: group I - control; group II - 0.5% zeolite; group III -F. poae extract; group IV-0.5% zeolite andF. poae extract. Broilers were sacrificed at 28 days for the measurement of relative organs weights, leukocyte counts and serum biochemical values. No mortality was recorded over the experiment. Body weight gains, feed intake, feed utilisation and water consumption were depressed by theF. poae extract (p<0.05). A decrease of these parameters were also observed in group IV which received the diet with zeolite and theF. poae extract. No significant differences were seen in group II when compared to control. In groups III and IV the relative weights of liver, kidney, hearth and gizzard were significantly increased (p<0.05), while in group II only the relative liver weight was increased.F. poae extract, administered singly or in combination with zeolite, significantly decreased leukocytes count, serum total protein and serum albumin. Zeolite andF. poae extract, singly or combined, increased serum creatinine and uric acid concentrations (p<0.05).These findings indicate that sublethal doses of F. poae extract can affect adversely the performances and the health in broiler chickens. By adding zeolite these impairments could not diminished and for some parameters the zeolite additive increased the adverse effects of the F. poae extract.

Dietary effects of Ca-zeolite supplementation on some blood and tibial bone characteristics of broilers

“…The results were in agreement with those in the literature (Dwyer et al, 1997;Keçeci et al, 1998;Curtui, 2000;Lotfollahian et al, 2004;Miles & Henry, 2007;Safaeikatouli et al, 2011). Altıner et al (2010) found that the total cholesterol levels of serum in laying hens fed rations with added microbial phytase and supplemented zeolites, were not considerably different.…”

“…Conversely, Park et al (2002) indicated that blood cholesterol concentration was significantly lower in 3.0% natural zeolite treatments than in the control. Curtui (2000) also reported that zeolite supplementation in the diet (0.5%) caused a significant decrease in total protein in serum, and an increase in uric acid concentration, whereas some researchers (Lotfollahian et al, 2004;Safaeikatouli et al, 2011) observed increases in the total serum protein concentration by 3% zeolite supplementation. On the other hand, Pond & Yen (1983) and Ward et al (1991) found no effect of Na-zeolite A or clinoptilolite on blood urea nitrogen.…”

EFFECTS OF DIETARY ZEOLITE LEVELS ON SOME BLOOD PARAMETERS OF GILTHEAD SEABREAM (Sparus aurata) JUVENILES

“…These variables in the present study, except ALT which had a significant quadratic contrast, were not significantly affected by the treatments, suggesting that dietary zeolite levels have no detrimental effect on fish health at least for gilthead sea bream. Similar findings were also reported by previous poultry and fish studies fed diets with varying zeolite levels (Curtui, 2000;Safaeikatouli et al, 2011;Vizcarra-Olvera et al, 2012).…”

“…Serum triglyceride levels showed a linear increase with dietary zeolite elevation in the present study. Previous studies report no effect of dietary zeolite on triglycerides levels of chick and fish (Curtui, 2000;Tekeşoğlu, 2010). The increase in cholesterol and triglycerides with zeolite supplementation could be partly resulted from a linear increase in lipid retention by fish fed zeolite added diets (Kanyılmaz et al, 2015).…”

“…These glucose levels are within the range of reported values for gilthead sea bream (Roncarati et al, 2006;Peres et al, 2013) In agreement with the present findings, a previous study on common carp (Kanyılmaz, 2008) reported a significant decrease in blood glucose concentrations with increasing dietary zeolite contents. However, there are several other studies on various aquatic and terrestrial animals pointing out that dietary zeolite had no effect on blood glucose levels (Curtui, 2000;Yazdani and Hajilari, 2009;Ghaemnia et al, 2010;Demirel et al, 2011;Safaeikatouli et al, 2011;Peres et al, 2013). Çelik (2006) and Çelik et al (2008) reported that when exposition of fish to heavy metals for a long time could have lowering effects on glucose levels.…”
