The purpose of the study was to evaluate the efficiency of 50% Nifursol for the control of trichomonosis in pigeons. The experiment was carried out under laboratory conditions on 6 groups of racing pigeons (24 pigeons in each group), divided into 3 sub-groups (isolated from each other) each with the same number of birds. Before the experiment was started, the health of the birds was examined. The pigeons selected for the study were free from Salmonella, Chlamydophila and Campylobacter. Before the pigeons were divided into the groups, they had been infected with a 48-hour culture of Trichomonas gallinae. The efficiency of the infection was determined by conducting parasitological examination 7 days after infection. Crop swabs were collected for microscope preparations and observations. The intensity of invasion was indicated by the number of pluses (+), depending on the number of Trichomonas gallinae in the visual area. Group I consisted of non-treated, infected birds. The birds in Groups II, III, IV and V received 50% Nifursol at doses of 150, 300, 600 and 1200 mg/kg of feed, respectively. Group VI also received 20% Metronidazol (reference drug) at a dose of 3g/l of water. The efficiency of the drugs used in the study was evaluated with regard to clinical observations and parasitological examinations conducted after 1, 2, 3, 4 and 6 weeks from the day the birds were found to be infected with Trichomonas gallinae. When the drug administration was accomplished, 10 pigeons from each group were randomly selected for haematological and biochemical examinations of blood samples. The results showed a high efficiency of 50% Nifursol administered at the doses of 600 and 1200 mg/kg of feed. The results obtained in our experiment also show that a dose of 600 mg/kg of feed administered to pigeons for a 4-week period is efficient for the treatment of Trichomonas gallinae invasion. The results obtained in clinical, biochemical and hematological studies prove that even long-term (up to 6 weeks) administration of 50% Nifursol at a dose not exceeding 600 mg/kg of feed is safe to the birds and will not deteriorate the physiological functions of inner organs in pigeons.

The aim of the study was to investigate the state of parasitic invasions in flocks of carrier and fancy pigeons in south-western Poland. Coproscopic methods (flotation with saturated NaCl and saccharose, as well as the McMaster method) were used to examine 42 pigeon flocks (18 flocks of fancy pigeons and 24 flocks of carrier pigeons). A total of 210 faeces samples were tested. Prevalence was determined, and average intensity and abundance of gastrointestinal parasites were estimated on the basis of OPG/EPG. Dispersive forms of parasites were found in 78.6% flocks (88.8% of fancy pigeons and 70.8% of carrier pigeons). In the flocks of fancy pigeons most invasions were of mixed character, with statistically significantly high indices of prevalence and abundance. In carrier pigeon flocks, monoinvasions with significantly higher indices of average intensity prevailed, which indicates a high risk of invasion in this group of birds. Eimeriosis was found to be the dominating invasion, occurring in 59.5% of all samples, carrier pigeons – 45.4%, fancy pigeons – 77.7% (59.5% of the flocks), average OPG – 12280, abundance – 7309. Capillariasis: in total – 49% samples, carrier pigeons – 35.8%, fancy pigeons – 66.6% (52.4% of the flocks), average EPG – 3216, abundance – 1577. Ascariasis: in total – 24.3% samples, carrier pigeons – 12.5%, fancy pigeons – 40% (28.6% of the flocks), average EPG – 1953, abundance – 474. Eggs of nematodes belonging to Ornithostrongylus were found in 4.2% of the samples in total: carrier pigeons – 3.3%, fancy pigeons – 5.5% (4.8% of the flocks), average EPG – 488, abundance – 20. Tapeworm eggs were found in 6.2% samples in total, carrier pigeons – 2.5%, fancy pigeons – 11.1% (9.5% of the flocks), average EPG – 607, abundance – 37. The correlation analysis showed relationships between the prevalence and diarrhoea only in the case of tapeworm invasion, no relationship between diarrhoea and the mere fact of infection were found in other invasions. However, a significant correlation was found between the average OPG/EPG of diagnosed parasites (especially Eimeria, Capillaria and Ascaridia) and the observed diarrhoea symptoms.

Celem badań była analiza wzrostu masy ciała i związanych z nią dwóch wymiarów gołębi w okresie od 7. dnia po wykluciu do 24. miesiąca życia. Badaniami objęto gołębie ras mięsnych: king, strasser i wrocławski mięsny oraz gołębie pocztowe. Łącznie zbadano 200 osobników (po 50 z każdej rasy). W celu przeanalizowania wzrostu ptaków ważono i mierzono je w wieku: 7, 14, 28 dni oraz 3, 6, 12 i 24 miesięcy. W wyniku badań stwierdzono, że w okresie od 7. dnia do 24. miesiąca życia największą masą ciała charakteryzowały się gołębie rasy king, a najmniejszą gołębie pocztowe, co wynika z różnych celów hodowlanych. Największą szerokość klatki piersiowej w całym okresie badań miały gołębie rasy king, a długość mostka – gołębie rasy strasser.

The aim of the study was to evaluate the body weight gain and the two related parameters in pigeons from the 7th day post hatching to the 24th month of life. The experiment was carried on meat-type breeds (King, Strasser, Wrocławski meat) and on Homing pigeon. A total of 200 birds (50 individuals per breed) were examined. The birds were weighed and measured at day 7, 14, 28 and 3, 6, 12, and 24 months of life. The obtained results showed that during the analyzed period the King breed was characterized by the highest body weight, while the Homing pigeon by the lowest one, what can result from different breeding goals. The biggest thorax width was stated in King breed and the longest crest of the bridge was found in Strasser pigeons.

Coccidiosis is a common disease in racing pigeons. The aim of this study was to assess the efficacy of toltrazuril in coccidiosis control in pigeons before and during the racing season. Bulk feces samples collected from 1140 birds were analyzed by the flotation method according to Fülleborn with the use of Darling’s solution. Eimeria spp. oocysts were counted in five fields of vision, and their diameter was an indicator of invasion intensity. Coccidiosis was controlled with toltrazuril (Baycox) applied twice at three-day intervals, at a dose of 20 mg/kg body weight, with drinking water. The severity of coccidial infection was determined one day prior to treatment, and the efficacy of toltrazuril was assessed 2, 4 and 6 weeks after treatment and 3 days after each race. Eimeria spp. were detected in all feces samples collected from 4 pigeon lofts. Two weeks after the first administration of toltrazuril, only single oocysts were present in feces samples, while no oocysts were found during the next examination. Coccidia appeared again in the excreta of racing pigeons (group 2) after the second and third race, whereas in pigeons that stayed in the loft (group 1) reinvasion was noted after the fourth race of group 2 birds. The results of the study indicate that Baycox administered twice was highly effective in controlling Eimeria spp. invasion over a period of more than ten weeks.
