Fig. 1 – white, punctate lesions in the duodenum

IV. FAECAL PARASITOLOGICAL EXAMINATION
Quantitative parasitological examination, McMaster chamber method according to Raynaud.
On day 25, the sample examined showed: 91,000 oocysts/1 g of faeces
V. DIAGNOSIS
INWAZJA EIMERIA SPP.
VI. RECOMMENDATIONS
BIOCOX in a dose of 500 ml/1000 l of drinking water, in ½ of the daily water drunk, for 3 days (from day 25 to 27)
VII. EFFECTS
On the 27th day, the herd was reassessed and the anatomopathological and parasitological examinations were repeated. A clear reduction in indigestion was observed (less feed was observed in stool), the herd is more balanced than before the start of the therapy. The anatomopathological examination did not reveal changes characteristic of Eimeria spp. invasion.
Parasitological examination revealed: 22,000 oocysts/1 g faeces.
VIII. SUMMARY
After treatment, the herd stabilized. There were no anatomopathological changes characteristic of Eimeria spp. invasion in the intestines. There was a significant reduction in the number of oocysts in 1 g of faeces (data presented in Table 1). After the therapy, the herd stabilized. There were no anatomopathological changes characteristic of Eimeria spp. invasion in the intestines. There was a significant reduction in the number of oocysts in 1 g of stool (data presented in Table 1). At the end of the production cycle, the birds compensated for the loss of body weight gain caused by the infection. The average body weight at the end of the flush was 2.98 kg (for a cycle duration of 40.8 days), the feed conversion ratio was 1.62. In the summary of production parameters, despite the occurrence of coccidiosis, this flush was successful – EWW coefficient 429.5.
