Untersuchungen zur ergotropen Wirksamkeit von 2,3-Dimethylchinoxalin-1,4-dioxid bzw. 2-Methylchinoxalin-1,4-dioxid am wachsenden Broiler bei Verwendung hydrokolloidreicher Rationen sowie von Broilermastalleinfutter

Abstract

2,3-dimethyl-quinoxaline-1,4-dioxide and 2-methyl-quinoxaline-1,4-dioxide proved to be ergotropic in the feeding of a hydrocolloid ration as well as of a broiler fattening feed. They are at least equal to Nitrovin. The ergotropic effect of the hydrocolloid ration was higher than that of the conventional ration. For this reason methylated quinoxaline-1,4-dioxides are considered as belonging to the intestinal stabilisers. They increased nutrient and energy retention and decreased feed efficiency by approximately equal to 10%. Residues in the liver, the kidneys and the intestines could only be detected after 10 times the ergotropic amount.
