Mode of Action
When used as a food additive, ractopamine added to feed can be distributed via the blood to the muscle tissues, where it will bind to specific beta receptors in the muscle cell membranes. A cascade of events will then be initiated to increase protein synthesis, which results in increase in muscle fiber size. Ractopamine is known to increase the rate of weight gain, improve feed efficiency and increase carcass leanness in finishing swine. Its use in finishing swine yields about three kilograms of additional lean pork and improves feed efficiency by 10%. In steers and heifers, ractopamine use increases hot carcass weight by about 5.5 kilograms and 5 kilograms, respectively.

Famous quotes containing the words mode of, mode and/or action:
“The mode of clearing and planting is to fell the trees, and burn once what will burn, then cut them up into suitable lengths, roll into heaps, and burn again; then, with a hoe, plant potatoes where you can come at the ground between the stumps and charred logs; for a first crop the ashes suffice for manure, and no hoeing being necessary the first year. In the fall, cut, roll, and burn again, and so on, till the land is cleared; and soon it is ready for grain, and to be laid down.”
—Henry David Thoreau (1817–1862)
“I cannot believe that our factory system is the best mode by which men may get clothing. The condition of the operatives is becoming every day more like that of the English; and it cannot be wondered at, since, as far as I have heard or observed, the principal object is, not that mankind may be well and honestly clad, but, unquestionably, that the corporations may be enriched.”
—Henry David Thoreau (1817–1862)
“The curse of me & my nation is that we always think things can be bettered by immediate action of some sort, any sort rather than no sort.”
—Ezra Pound (1885–1972)
