    摘要: The invention relates to a novel metabolite, M.139603, of the empirical formula C.sub.35 H.sub.53 O.sub.8 Na, which is obtained from the aerobic fermentation of a novel Streptomyces species, NCIB 11426, and to the corresponding free acid form thereof, C.sub.35 H.sub.54 O.sub.8. M.139,603 reduces the proportion of methane produced by the "digestion" of food in the rumen of ruminant animals and increases the proportion of propionate to acetate in the rumen contents. The compound is therefore useful for increasing the growth rate of ruminant animals, and/or for increasing their efficiency of food conversion. The compound also possesses activity against Gram positive micro-organisms, and against coccidia, for example Eimeria tenella.

    摘要: This invention relates to the use of aplasmomycin, boromycin and acylated and hydrogenated derivatives thereof for modifying rumen metabolism in domestic ruminant animals, by reducing the proportion of methane formed, and increasing the proportion of propionate at the expense of methane and/or acetate. This modification of rumen metabolism is believed to improve growth in ruminant animals. The disclosure also describes compositions which may be used in the claimed method, an improved process for the production of aplasmomycin, and novel analogs of aplasmomycin and boromycin together with processes for their manufacture.
