Effect of clinoptilolite on serum biochemical and haematological characters of broiler chickens during aflatoxicosis
Scopus
Toplam 144 atıf DOI
Clinoptilolite (CLI, a natural zeolite) incorporated into the diet at 1.5 and 2.5 per cent were evaluated for their ability to reduce the deleterious effects of 2.5 mg total aflatoxin (AF) kg-1 diet on broiler chickens from 1 to 21 days of age. In total 360 broiler chicks were divided into six equal treatment groups (control, AF, CLI (1.5 per cent), AF plus CLI (1.5 per cent), CLI (2.5 per cent) and AF plus CLI (2.5 per cent)). When compared with the controls, AF treatment significantly decreased serum total protein, albumin, inorganic phosphorus, uric acid, total cholesterol and the values of haematocrit, red blood cell counts, mean corpuscular volume, haemoglobin, thrombocyte counts, percentage of monocyte counts; increased values of white blood cell and heterophil counts. The addition of CLI (1.5 per cent) and CLI (2.5 per cent) to the AF-containing diet reduced the adverse effects of AF and should be helpful in a solution to the aflatoxicosis problem in poultry.

In this study, total aflatoxin (AF) and a natural zeolite (clinoptilolite ; CLI) were added to the broiler feed and development of humoral immunity against Infectious Bronchitis (IB) and Newcastle Disease (ND) was evaluated. A total of 576 1-d-old Ross broiler chicks (96 per each) were housed in six treatment groups [Control, CLI (15 g/kg diet), 50 ppb AF, 50 ppb AF plus CLI, 100 ppb AF, 100 ppb AF plus CLI] and fed for 42 days. Compared to controls, the antibody titres of IB were determined significantly lower (p < 0.05) in 50 and 100 ppb AF fed chicks from 20 to 42 days of age. The ND titres were also significantly lower (p < 0.05) in 100 ppb AF fed chicks, while no significant differences were seen in 50 ppb AF group compared to controls (p < 0.05). The addition of CLI to the AF-containing diets (50 and 100 ppb) significantly ameliorated (p < 0.05) the adverse effect of AF on humoral immunity. The single addition of CLI to the AF-free diet had no adverse effects in chicks, except the IB titres on 42nd day.
