Reproductive performance in mammalian and avian species is stimulated by administering an effective amount of one or more compounds of any of Formulas I, II or III, typically at the rate of 0.01 to 2 mg/kg/day:
(I) a compound of the formula:
wherein
R represents C1-C4 alkoxy, with the proviso that R is in the 4 or 5 ring position,
n represents the integers 0, 1 or 2, and
A represents -OH, -NH2 or
where R' represents C1-C4 alkyl,
or physiologically acceptable salts thereof;
(11) a compound of the formula:
wherein
R represents C1-C4 alkoxy, with the proviso that R is in the 5 or 6 ring position, and
n represents one of the integers 0, 1 or 2; and
(III) a compound of the formula:
wherein
R represents C1-C4 alkoxy, with the proviso that R is in the 6 or 7 ring position, and
n represents one of the integers 0, 1 or 2;
or physiologically acceptable salts thereof.
The active compounds are incorporated in novel feed concentrates and feed compositions or parenteral dosage forms or implants utilized according to the recited method.
通过施用有效量的一种或多种配方 I、II 或 III 中的任何一种化合物,通常以 0.01 至 2 毫克/千克/天的剂量,可刺激哺乳动物和鸟类的繁殖性能:
(I) 式中化合物:
其中
R 代表 C1-C4 烷氧基,但 R 位于 4 或 5 环位置、
n 代表整数 0、1 或 2,以及
A 代表-OH、-NH2 或
其中 R' 代表 C1-C4 烷基、
或其生理上可接受的盐类;
(11) 式中化合物:
其中
R 代表 C1-C4 烷氧基,但 R 位于 5 或 6 环位置,且
n 代表 0、1 或 2 整数之一;以及
(III) 式中化合物:
其中
R 代表 C1-C4 烷氧基,但 R 位于 6 或 7 环位置,且
n 代表 0、1 或 2 整数之一;
或其生理上可接受的盐类。
根据所述方法,将活性化合物加入新型饲料浓缩物和饲料组合物或非肠外剂型或植入物中。
