Description:
Melengestrol acetate (INN, USAN), sometimes abbreviated as MGA, is a steroidal progestin and antineoplastic agent. It is not approved for use in humans, and is instead used as a feed additive to promote growth in cattle, a purpose it is licensed for in the United States and Canada. It is an acetate ester of melengestrol, which in contrast, is not used in either animals orhumans.
Applications:
Progestogens are synthetic forms of the naturally occurring hormone, progesterone. Progesterone is produced by the corpus luteum [CL]. By negative feedback, it reduces pituitary function, thus preventing a female from coming into heat. When administered in conjunction with a luteolytic agent, such as PGF2a or estradiol valerate, progestogens can provide an effective means of resetting the cow's physiological clock. If the progestogen is administered for several days, an artificial corpus luteum can in effect be installed, which can be removed at the producer's discretion.
Superiority
Estrogen is a female sex hormone, produced by the ovaries and placenta. Adrenal cortex also produced a few estrogen. Female children after puberty ovarian secretion of estrogen, start, in order to promote the vagina, uterus, fallopian tube and ovary itself development, at the same time caused menstrual endometrial hyperplasia. Estrogen can promote the subcutaneous fat accumulation, plump
hyperplasia of the breast, nipple, areola dark colors, and produce sexual desire
to promote the body sodium and water retention, bone calcium deposition |
