The National Academies Press. The structure of the industries also affects the ease of identifying the source of a problem whether it is a pathogenic microorganism, a drug residue, or an antibiotic-resistant bacteria and the ease with which consumer preferences flow back through the system to stimulate changes in the genetics and breeding of stock to produce the desired product.

In all of the animal industries, antibiotic drugs are used for three primary reasons: Subtherapeutic doses are used when pathogens are known to be present in the environment or when animals encounter a high-stress situation and are more susceptible to pathogens.

Subtherapeutic doses are smaller than those required to treat established infections. They might also use compounds developed exclusively as production enhancers that have no therapeutic purpose. As summarized in Cromwellthere are three mechanisms of action through which antibiotics appear to enhance growth and production. The first involves direct biochemical events that are affected by antibiotics: The second involves direct effects on metabolism, including the effects of antibiotics on the generation of essential vitamins and cofactors by intestinal microbes and the way that antibiotics affect the population of microbes that make these nutrients.

In addition, the feeding of antibiotics is associated with decreases in gut mass, increased intestinal absorption of nutrients, and energy sparing. This results in a reduction in the nutrient cost for maintenance, so that a larger portion of consumed nutrients can be used for growth and production, thereby improving the efficiency of nutrient use for productive functions.

The third proposed mechanism of action is eliminating subclinical populations of pathogenic microorganisms. The elimination of this route of metabolic drain allows more efficient use of nutrients for production. The goal of an efficient livestock operation is to maintain animals that are free of disease or injury, that gain weight well if they are intended for market, or that stay in optimal condition if they are kept as breeding stock.

Leaving sickness or injury untreated is the most expensive alternative for the owner and is certainly the least humane for the animal. The strategies for raising food animals are pertinent to the larger issue of human health effects from drug use in food animals. The intensiveness of farm production in this country has increased because of the advantages inherent in the use of drugs that prevent or control infection and promote growth in animals.

Strong incentives for the use of these drugs exist to assure the public that only healthy animals enter the food chain and to maintain the profitability of the industry. A significant limit to animal production efficiency is any form of disease stress that animals might encounter in their production lives. Traditional growth promoters, such as the steroidal and nonsteroidal estrogenic agents, are less effective when used, because even low-grade disease affects general metabolism.

For this reason, pharmacological strategies to prevent or treat animal diseases are used, and the drugs of choice for bacterial infections are antibiotics.

Adequate use of antibiotics is necessary for several reasons. Improvements in feed efficiency reduce environmental pollution, for example, through reduced nitrogen and phosphorus losses in animal waste products.

Illness in herds and flocks decreases production and nutritional use efficiency Elsasser et al. Klasing and co-workers suggested that the antigenic challenge of the immune system in animals fighting off disease stress and illness causes repartitioning of nutrients away from growth and production to support the mechanisms that participate in restoring homeostasis and health.

Repartitioning of nutrients is a process in which hormone and immune cytokines direct one type of cell to not take up and use a given nutrient and to spare the availability of that nutrient while facilitating other cells e.
