Technical Abstract: Effects of dietary diacetoxyscirpenol and fusaric acid were determined on day-old turkey poults by randomly placing poults in batteries and feeding them one of four dietary treatments: control (C); control plus 4ppm diacetoxyscirpenol (DAS); control plus 300ppm fusaric acid (FA); and control plus 4ppm DAS and 300ppm FA (DF). There were 10 poults per pen with 6 replicate pens per treatment. Individual BW, BW gains (BWG) and pen feed consumption were determined at d6, 12, and 18. Period and cumulative feed to gain was calculated. Relative liver, spleen, bursa, intestine, and jejunum weights were measured at d18. Mouth lesions were scored for treatments at d18. Performance parameters were regressed on treatment means using the GLM Procedure of SAS®. Means were separated using LSMEANS with significance level set at P0.05. FA had no effect on BW or BWG at any period compared to C. Poults fed DF had reduced BW and BWG compared to C, while poults fed DAS had lower BW than all treatments at every period. Final BW were: C (451.7g), FA (464.9g), DF (389.0g), and DAS (351.4g). Poults fed FA or C had better feed to gain than poults fed DAS or DF (1.05 and 1.04 vs. 1.19 and 1.15, respectively) at d6. However, the effect of FA was transient: there were no differences among the treatments at d12 or d18. Poults fed FA had significantly lower relative intestine wt than poults fed other diets, and had significantly higher relative bursa wt at d18 when compared to poults fed DAS or DF. Poults fed DAS or DF had higher mouth lesion scores than poults fed FA or C, but mouth lesion scores in DAS and DF poults were not different from each other (4.48 vs. 4.64). In conclusion, dietary DAS resulted in decreased poult performance, while dietary FA had little or no effect. However, FA fed in combination with DAS resulted in some protective effect towards DAS.
