Reference


Thirty ‘day-old‘ chickens of mixed sex were purchased from a commercial hatchery on two separate occasions and groups of 10 placed in tubs. The birds were fed a commercial chick starter ration, containing 3-5-dinitro-orthotoluamide and zinc bacitracin as the coccidiostat and growth promoter respectively, for the first 2 weeks while in the third week broiler grower pellets containing monensin and virginiamycin were offered. In each of the two replicates one group was dosed with ampicillin and the other with tylosin. The agents were dissolved in water (180 mg/l ampicillin and 550 mg/l tylosin) and the medicated water offered for 5d commencing immediately after the fourth swab had been collected.

Swabs of cloacal faeces were taken from the same five chickens in each of the three tubs on the day of arrival and then on alternate days thereafter until day 23.
