WebThe structure of four ionophores used as anticoccidials, monensin, salinomycin, lasalocid and narasin are given in Table 1. Maduramycin is a further compound currently in use at 5 ppm in feed (Kantor et al., 1984). The ionophores have a wide spectrum of activity, but rather a narrow range of safety. However, despite reported monensin-resistant ... WebThe toxic dose of ionophores is decreased if they are used in conjunction with tiamulin, erythromycin, or chloramphenicol. Salinomycin at the dose recommended for chickens (60 g/ton) is toxic for turkeys; doses >15 g/ton are toxic in turkeys. Monensin (100 g/ton) and lasalocid (100 g/ton) at the dose recommended for chickens are not toxic to ...
