Mycotoxins are fungi toxic metabolites, heterogeneous in their nature and with varied pharmacological actions. They can cause injuries to animals, resulting in decreased performance and serious pathologic lesion. In the last years, the mycotoxicosis has received special attention worldwide due to losses in poultry industry. Fusarium fungi are reported as producers of diverse mycotoxin. Therefore, intoxication caused by Fusarium mycotoxins will hardly be due to one separate substance and more information is needed about the interaction effect of these.

The objective of lhe experiment was to evaluate the performance of broiler chickens in different leveis of acid folie ana nicotinic. A total number of 400 one-day-old male chicks, of Hubbard Une were used in a design completely randomized factorial 2x2, with two vitamins (folie and nicotinic acid) and two leveis (high and tow), being each experimental unit composed 0/20 birds. The vitamins leveis used are average leveis used by the most important raising poultry industry in the southem of Brazil. The vitamins used were defined in two leveis, low (80% of medium levei) and high (120% of medium levei). The fed diets were formulated to be isonutritives, changing onty the studied vitamins. At the end ofthe period, the fouawing parameters were evaluated: feed intake, body weight gain, feed conversion, productive efficiency Index, liver weight, abdominal fat weight. and carcass yield. No statistical diferences were found in the parameters observed. The results found at the end of the experiment suggested that low leveis could be used, without performance damages.SUMMARY The objective of lhe experiment was to evaluate the performance of broiler chickens in different leveis of acid folie ana nicotinic.

Broiler breeders (Ross Line) were submitted to three different systems of feeding intervals namely: T1= 48/48h, T2 = scheme 5/2 and T3 = 48/57/63h. The study 1 was during the growing period from the fifth to the twentieth week. The variables studied in this assay were: body weight, uniformity, viability, weight gain and feed conversion. In the study 2, which as developed from the 29th to 44th week of age, the residual effect of the assay 1 was evaluated in regard to the productivity parameters. The variables mensured were egg production, egg weight, hatchability percentage and feed conversion per eggdozen. Data collected were subjected to analyses of variance and the differences were compared by the Tukey test. In the study 1 the increasing feed intervals resulted in better body weight uniformity as well as better feeding conversion (P 0.05). The results were lower in the parameters of weight of gain and feed conversion for the birds that had received the smaller feed interval (P 0.05), the production data shoved hight similarity in the different treatments.
