“…DISCUSSION The results of this trial confirm that monensin may provide protection against coccidiosis for young poults reared on the floor. Similar conclusions have been reached by Anderson et al (1976) andMcDougald (1976). These results also suggest that the drug may be safely withdrawn at 10 weeks without mortality or reduction in weight gain due to coccidiosis ensuing.…”

SUMMARYMonensin at 60, 80 or 100 ppm provided sufficient early protection against coccidiosis in floor-pens seeded with a mixture of Eimeria adenoeides, E. gallopavonis and E. meleagrimitis oocysts to prevent mortality due to coccidiosis and permit satisfactory weight gains. Unmedicated poults suffered 7% mortality and significantly (P 0.05) reduced weight gains compared with medicated birds. No mortality occurred after medication was withdrawn at 10 weeks of age.In poults fed monensin at concentrations of 60, 80 and 100 ppm immunity development was sufficient to prevent mortality and weight loss in challenged poults. Some delay in development of immunity in birds medicated at 80 or 100 ppm was indicated by comparing lesion scores with those of unmedicated poults.Greater immunity occurred in all floor-pen reared groups (medicated or unmedicated) when compared with battery-reared, susceptible controls of the same age. Development of immunity, measured by lesion scores, occurred less rapidly in the caecal regions than in the upper intestine suggesting that E. meleagrimitis (upper intestine) may be more immunogenic than the other two species which largely parasitise the caecum.

“…Monensin shows promise in the control of turkey coccidiosis (Anderson et al, 1976;McDougald, 1976) but effects of withdrawal are unknown. Monensin alters oocyst production and may affect immunity development (Karlsson and Reid, 1978).…”

Halofuginone (HAL) and monensin (MON) were effective in controlling coccidiosis in turkey poults when included in the feed at concentrations of 2 and 66 ppm respectively. At 10 and 14 weeks of age, body weight and feed intake were greater in poults given HAL with bambermycins (BAM) than in poults given HAL or MON with bacitracin methylene disalicylate (BAC). Poults given two anticoccidial drugs (MON followed by HAL or HAL followed by MON) weighed more and had a lower feed conversion than poults that received no medication, but no difference was found in the performance of turkeys given one or two anticoccidial drugs. There were no differences in performance whether HAL was used before or after the use of MON. None of the drugs completely suppressed oocyst production. At 11 weeks of age, an increase in the number of oocysts in the droppings was noted following drug withdrawal, but no increase was observed in the number of oocysts in the litter. There was no indication of clinical coccidiosis after drug withdrawal.

“…Monensin (Anderson et al, 1976;McDougald, 1976) was introduced in the 1970s, and for many years has been the most widely used ionophore for the control of coccidiosis in turkeys. Other ionophores effective against Eimeria in the turkey are lasalocid (Mitrovic et al, 1979), and maduramicin (Wang et al, 1989).…”
