- Such feed and food can be used for medicinal purposes as well as for prophylactic purposes.
- Such feed or food is produced by mixing a concentrate or a premix containing 0.5 to 30%, preferably 1 to 20% by weight of an active ingredient in admixture with an edible organic or inorganic carrier with conventional feed.
- Edible carriers are e.g. Corn meal or corn and soybean meal or mineral salts, which preferably contain a small amount of an edible dust control oil, e.g. Corn oil or soybean oil.
- the premix obtained in this way can then be added to the complete feed before it is fed to the animals.
- the minimum inhibitory concentrations (MIC) of the compounds according to the invention were determined by serial dilution on Iso-Sensitest Agar (Oxoid). A series of agar plates were prepared for each test substance, which contained decreasing concentrations of the active ingredient at twice the dilution. The agar plates were inoculated with a multipoint inoculator (Denley). Overnight cultures of the pathogens were used for inoculation, which had previously been diluted so that each inoculation point contained approximately IO 4 colony-forming particles. The inoculated agar plates were incubated at 37 ° C and the germ growth was read after about 20 hours. The MIC value ( ⁇ g / ml) indicates the lowest active substance concentration at which no growth was visible to the naked eye. The MIC values for mycoplasmas were recorded microscopically after an incubation period of 5 to 7 days.
- Example 1 Example 2 Example 3 Example 4
- the antibacterial activity of the compound according to the invention in vivo was determined as follows. Chicken chicks two to three weeks old (Lohmann hybrids, Lohmann, Cuxhaven) were infected intrathoracically with 5 x IO 6 CFU / ml of the E. coli strain 6200 Serovar 078 (Prof. Hinz, Hanover). Immediately after the infection, groups of 10 to 20 chicks were given the active ingredient orally. 6 dilutions of a geometric dilution series were tested. The evaluation was carried out by recording the mortality rate 48 hours after the infection. The effectiveness of the compound in question is given as ED 90 in mg / kg.
