Newly weaned piglets and young poultry are highly susceptible to various stressors, such as bacterial diseases resulting in decreased growth and even death (Lecce, 1986; Hoerr, 1998). Supplementing antibiotics in swine and poultry diets at subtherapeutic levels has long been shown to increase the growth rate (Becker et al., 1955; Stahly et al., 1980; Cromwell, 2002). However, due to growing con...

The purpose of this review is to summarize the effectiveness, modes action and commercial application herbal plants their derivatives as growth promoters for animal.

To dissolve issue, several studies concentrated on new alternative resource, but others have tr...

The key to optimal animal production is a balanced gut. Performance pressure renders broilers vulnerable to infectious and/or non-infectious triggers. With the European withdrawal of antimicrobial growth promoters (AGP) in 2006, enteric broiler diseases became more prevalent in the EU. A common syndrome causing intestinal health aberrance is called ‘dysbiosis’ or ‘dysbacteriosis’ [1]. This cond...

The use of antibiotics as growth promoters (AGP) in poultry feed aims to stimulate and prevent disease. However, the animal has been banned spread resistant bacteria which can be harmful human health. natural compounds, especially essential oils, a alternative for antibiotics. aim study was evaluate inclusion eugenol clove leaf oil additive replace on immune organs performance male laying hens....

Before an antibiotic can be legally marketed in Australia it must be evaluated by the National Registration Authority for safety to the public, the operator, the environment and the target species. The efficacy of the product, its justification for use and the residue profile are also evaluated. Residue and trade issues are assessed and appropriate controls and labelling applied. While manageme...

Modern food animal production depends in large part on the use of antibiotics for disease control and growth promotion. This practice has left many in Denmark concerned about its potential effect on the efficacy of these important drugs. In 1969, the Swann committee recommended that those antibiotics used for the treatment of infections in animals and humans not be used as growth promoters, a p...

However, intensification use synthetic fertilizers has serious harmful impacts human health and environment.
