Influence of fusariotoxins on growing and slaughtering perfomance of broilers.
Abstract
In a feeding trial with 180 broilers the impact of mycotoxin contaminated maize on growing and slaughtering performance, and on physiological parameters was investigated. 4 feeding groups with different levels of contamination were used in the experiment. Feeding group 1, 2, 3 and 4 was fed with 54.6, 36.4, 18.2 and 0 % uncontaminated and 0, 18.2, 36.4 and 54.6 % highly contaminated maize, respectively. Highly mycotoxincontaminated maize contained 9.8 mg DON, 1.04 mg MON, 1.43 mg BEA, 0.105 mg FB1/kg. Other components of the diet were 31.4 % soyabean meal, 4.4 % oil, 3 % maize gluten feed, 3 % grass meal, 0.015 % L-lysin-HCl, 0.141 % DL-methionin, 1.22 % limestone, 1.63 % dicalcium-P, 0.15 % salt, 0.16 % NaHCO3, 0.015 % vitamin premix, 0.040 % trace element premix, 0.080 % cholin-Cl, 0.050 % coccidiostaticum. At the end of the growing period (37 days) the chickens of feeding group 1, 2, 3 and 4 had a life weight of 1896, 1942, 1904, and 1943 g and the feed conversion rates were 1.81, 1.77, 1.83 and 1.82 kg/kg LW-gain, respectively. The contaminated diets had no significant impact on life weight gain, feed conversion rate and liver weight, but did significantly increase heart weight. The chemical composition of carcass and the physiolgical parameters of the blood (AST, LDH, triglycerid and cholesterin) were not affected. The experiment shows, that maize contaminated with Fusarium to-xins had no negative effects on growing and slaughtering performance and on meat quality (tender-ness, juiciness and taste), and on blood parameters. The possible low absorption rate of Fusarium toxins in the digestive tract seems to be the main reason for their low toxicity and the absence of synergistic effects between mycotoxins.
