Dose response study of enrofloxacin against Riemerella anatipestifer septicaemia in Muscovy and Pekin ducklings.

The efficacy of enrofloxacin against Riemerella anatipestifer (formerly Pasteurella anatipestifer) septicaemia of Muscovy and Pekin ducklings was assessed in an artificial challenge model which reproduced typical duck riemerellosis with very high mortality. Mortality, clinical signs, gross lesions, microbiological clearance, feed intake and body weight gain were the efficacy criteria studied. A pulsing medication in drinking water for 4 h at 25, 50 or 100 ppm enrofloxacin on the first day, followed by 12.

[The survival ability of salmonella, coccidia oocysts and ascarid eggs in laying hen feces from different housing systems].

The time of survival of Salmonella typhimurium, coccidia oocysts and ascaris eggs in manure of layer was determined in 5 different housing systems and 2 storing places for litter. The experiments were carried out in a stable of experimental station Frankenforst of the university of Bonn with a flock of 2200 hens. The effects of the environment conditions temperature, dry matter content, pH-value and intestinal microflora of the manure have also been studied.
