biologicaladjective Referring to biology; biologic.
noun Biologic. Any of a number of FDA-regulated agents—e.g., antitoxins, antisera, vaccines and blood plasma products—prepared from donor pools or obtained directly from various living organisms, often mammals. They are not amenable to the chemical or physical standardisation steps required of pharmaceuticals; they are impure chemically and safety cannot be assumed.

usually comprise a list of vital statistics about an animal or plant species, recording such things as preferred growth medium, temperature and humidity and details of the internal milieu including blood pH, normal blood electrolytes and the like.
includes the influence of all biological factors such as warmth, moisture and humidity, but also the plant ecosystem in which the animal lives and the associated populations of vertebrates and invertebrates that may compete for food and space, and may also act as reservoirs for infectious diseases.

is an estimate of the biological importance of a statistical or apparent causal association between two variables, e.g. feed supply and the occurrence of bovine acetonemia. The estimation takes into account the possible biological relationship between the two; an estimate of statistical significance would take only the mathematical relationship into account.
