Abstract

The authors examined the effect of MYCO-AD containing hydrated sodium calcium aluminium silicate (Delacon Biotechnik Ges. m. b. H.) on T-2 toxicosis in broiler chickens by experimental feeding. Testing chickens were divided into 3 groups, 25 birds each. Group I. (control group) got toxin-free feed, group II. got feed containing 1 mg/feed kg T-2 toxin, group III. got feed containing 1 mg/feed kg T-2 toxin and 2.5 kg/feed ton (=2.5 g/feed kg) MYCO-AD too from the day of hatching until the 40th day. T-2 toxin was produced by fungus Fusarium sporotrichoides on rice substratum. At the end of the trial, in the group II. the feed intake was 21% behind and the body mass was 23% behind the control group, respectively. In the case of 80-90% of animals on the mucosa of the mouth and on the corner of the bill necrotic sediments were stated. In the Bursa Fabricii and the thymus a decrease of diameter of follicles and lobes, and a reduced amount of lymphocytes were determined. No animal dropped out. At the end of the trial, in one third of the animals killed in the hypodermic interstitial tissue oedematous infiltration, in the abdominal cavity accumulation of a straw-yellow liquid were observed. The effect of T-2 toxin was almost completely prevented by feeding MYCO-AD. Feed-intake, gain in weight and feed conversion of group III. were equal with those of the control group, and some values were even more favourable in group III. than in the control group. In about 15-30% of animals lesions of mouth were stated in a moderate way, but it did not affect the development of animals. There were no histopathological changes in the internal organs. On the basis of the evaluation of results of the trial it can be established that toxicosis caused by 1 mg T-2 toxin/feed kg in broiler chickens can be prevented by feeding 2.5 kg MYCO-AD/feed ton.
