摘要

Embonic acid salts of Spiramycin I, II or III or of a mixture of at least two of them may be prepared by effecting double decomposition in aqueous solution between a water-soluble salt, particularly an alkali metal salt, of embonic acid and a water-soluble spiramycin salt such as the sulphate or phosphate. Specification 758,726 is referred to.ALSO:Food for animals contains a proportion of an embonic acid salt p of spiromycin sufficient to accelerate the growth of the animals, the total content of spiramycin salt preferably lying between 5 and 50 grams per metric ton of feed. An example describes the addition of the embonate of a mixture of spiramycin I, II and III to a pig food containing by weight, 76% maize flour, 17% soya flour, 2% meat meal, 1% fish meal, 2% lucerne meal and 2% chalk, calcium phosphate and sodium chloride.
