Efficacy of Monensin against Turkey Coccidiosis in Laboratory and Floor-Pen Experiments

Monensin at 60, 80, or 100 ppm in feed reduced mortality and lesion scores while protecting against weight loss of turkeys infected with the major pathogenic species: Eimeria adenoides, E. meleagrimitis, and E. gallopavonis. With single and mixed infections in battery-cage experiments, the death rate of unmedicated turkey poults was 33-75%. Weight gains were significantly (P is less than or equal to 0.05) better with 100 ppm monensin than 60 ppm, as were also lesion scores. Under floor-pen conditions there were no significant differences among monensin treatments. Moisture content of the litter was significantly lower in all monensin-medicated pens (40%, compared with 52% moisture in pens of unmedicated controls).

Safety of Sulfadimethoxine Potentiated Mixture (Rofenaid®), a New Broad Spectrum Coccidiostat-Antibacterial, in Turkeys

INTRODUCTIONROFENAID® is a new broad spectrum coccidiostat and antibacterial containing sulfadimethoxine (N′-[2, 6-dimethoxy-4-pyrimidinyl] sulfanilamide) potentiated with ormetoprim (2, 4-diamino-5-[4, 5-dimethoxy-2-methylbenzyl] pyrimidine) in a ratio of 5:3. Sulfadimethoxine alone has been shown to be highly effective, therapeutically, against all pathogenic species of coccidia in chickens (0.05%) and turkeys (0.025%) when administered in the drinking water (Mitrovic and Bauernfeind, 1967) and efficacious in the prevention of turkey coccidiosis at 0.0125% in the feed (Mitrovic, 1968). Mitrovic (1967) reported that sulfadimethoxine was also effective in the therapy of fowl cholera in chickens (0.05%) and turkeys (0.025%) and infectious coryza in chickens (0.05%) when administered in the drinking water. The combination of sulfadimethoxine and the potentiator ormetoprim, a folic acid antagonist, in a 5:3 ratio results in enhanced broad spectrum coccidiostatic and antibacterial activity when fed continuously to broilers at 0.02% and replacement birds at 0.01% (Mitrovic et al., 1969 a, b).…

The Response of Recently Isolated Strains of Eimeria meleagrimitis to Chemotherapy

Three strains of E. meleagrimitis were isolated from outbreaks of coccidiosis in turkeys in Sussex, Yorkshire and Carmarthenshire respectively; all 3 strains failed to respond to the normal preventive level of sulphaquinoxaline (0.0125%), amprolium (0.0125%), clopidol (0.0125%), deccoquinate (0.004%), 3,5-dinitro-o-toluamide (Zoalene, 0.0125%).

Safety and Compatibility of Sulfadimethoxine Potentiated Mixture (Ro 5–0013) , a New Broad Spectrum Coccidiostat-Antibacterial, in Chickens

Ro 5–0013 is a new broad spectrum coccidiostat and antibacterial containing sulfadimethoxine, N′-(2,6-dimethoxy-4-pyrimidinyl) sulfanilamide and potentiator, 2,4 diamino-5-(4,5-dimethoxy-2-methylbenzyl) pyrimidine, hereafter referred to as the potentiator, in a ratio of 5:3. Sulfadimethoxine alone has been reported to be highly effective, therapeutically, against all pathogenic species of coccidia in chickens (0.05%) and turkeys (0.025%) when administered in the drinking water (Mitrovic and Bauernfeind, 1967) and efficacious in the prevention of turkey coccidiosis at 0.0125% in the feed (Mitrovic, 1968). Mitrovic (1967) found that sulfadimethoxine was also effective in the therapy of fowl cholera in chickens (0.05%) and turkeys (0.025%) and infectious coryza in chickens (0.05%) when administered in the drinking water. Combining sulfadimethoxine and the potentiator, a folic acid antagonist, in a 5:3 ratio (Ro 5–0013) results in enhanced broad spectrum coccidiostatic and antibacterial activity when fed continuously to broilers at 0.02% and replacement birds at 0.01% (Mitrovic et al.,…

Sulfadimethoxine in Prevention of Turkey Coccidiosis

SULFADIMETHOXINE, N′-(2,6-dimethoxy-4-pyrimidinyl) sulfanilamide, since first synthesized by Bretschneider and Kloetzer (1955), and its antibacterial activity reported by Schnitzer et al. (1958), has stimulated a great deal of interest among the workers engaged in the field of experimental chemotherapy. In fowl, Mitrovic and Bauernfeind (1967) reported that sulfadimethoxine was therapeutically highly effective against all pathogenic species of Eimeria in chickens and turkeys. Mitrovic (1967) reported that sulfadimethoxine was also effective in therapy of fowl cholera in chickens and turkeys and infectious coryza in chickens.Since the chemoprophylactic efficacy of sulfadimethoxine in turkey coccidiosis has not as yet been investigated, the studies undertaken and completed are the object of this report.MATERIALS AND METHODSThe chemoprophylactic efficacy studies were carried out in battery and floor pen trials.Battery trials and experimental design. Day old Broad Breasted White (BBW) turkey poults, obtained from a commercial hatchery, were kept in wire floored, .

EIMERIA NINA-KOHL-YAKIMOVI YAKIMOF AND RASTEGAIEFF, 193° IN AN ANGORA GOAT

Coccidiosis of domestic animals has been studied extensively but not in an equal degree in all species. Chicken coccidiosis, for example, has been studied a great deal, while coccidiosis in cattle, sheep and goats has received very little attention. For a long time many authors have written about the danger of coccidiosis in sheep and goats I, 2, 3, 7, 8, 9, ıı, 13, 14. According to several 'of them 9, 16, 20 mortality in lambs and kids from coccidiosis is 10 % to go % .In Turkey coccidiosis is wide spread among Angora goats, especially among the young' animals, in which it causes emaciation, stunding and even death 17. Little work has been done on the coccidiosis in Angora goats up to present time. This indicates that the coccidia and the disease they cause need to be studied in detai!.
