Necrotic oral lesions in chickens fed diacetoxyscirpenol, T-2 toxin, and crotocin
Abstract:
One-day-old broiler chicks were fed a diet containing either 5 ppm diacetoxyscirpenol (DAS), 5 ppm T-2 toxin, 10 ppm crotocin, or a control diet for 3 weeks. Chicks fed the diet containing DAS and T-2 toxin showed yellowish plaque-type lesions on the beak, tongue, and angle of the mouth. Crotocin did not cause such lesions nor any apparent clinical signs. Chicks fed DAS had the lowest weight gain followed by the T-2, crotocin, and control group in that order; however, chicks fed crotocin had the poorest feed conversion ratio.
Insights
Diacetoxyscirpenol (DAS) and T-2 toxin caused oral lesions and reduced weight gain in broiler chicks. Crotocin did not cause lesions but impaired feed conversion, highlighting mycotoxin risks in poultry.
Area of Science:
- Animal Science
- Toxicology
- Poultry Nutrition
Background:
- Mycotoxins, such as diacetoxyscirpenol (DAS), T-2 toxin, and crotocin, are contaminants in animal feed.
- These toxins can negatively impact animal health, growth, and productivity, posing economic challenges in the poultry industry.
Purpose of the Study:
- To investigate the toxicological effects of diacetoxyscirpenol (DAS), T-2 toxin, and crotocin on broiler chicks.
- To evaluate the impact of these mycotoxins on chick growth, clinical signs, and feed conversion ratios.
Main Methods:
- One-day-old broiler chicks were fed diets containing 5 ppm DAS, 5 ppm T-2 toxin, 10 ppm crotocin, or a control diet.
- The experimental feeding period lasted for 3 weeks.
- Clinical signs, including oral lesions, weight gain, and feed conversion ratio, were monitored.
Main Results:
- Chicks fed DAS and T-2 toxin developed yellowish, plaque-type lesions in the mouth, beak, and tongue.
- DAS and T-2 toxin significantly reduced weight gain in broiler chicks.
- Crotocin did not induce oral lesions but resulted in the poorest feed conversion ratio among all groups.
Conclusions:
- Diacetoxyscirpenol (DAS) and T-2 toxin exhibit oral toxicity and growth-inhibiting effects in broiler chicks.
- Crotocin, while not causing overt lesions, negatively impacts feed efficiency in poultry.
- These findings underscore the importance of monitoring and managing mycotoxin contamination in poultry feed to ensure animal health and productivity.
