Antimicrobials in poultry
Antimicrobial agents are essential tools for treating and controlling bacterial infections in poultry production. Veterinarians have a huge responsibility when using antimicrobials in poultry producing meat and eggs for human consumption. The term ‘judicious use’ of antimicrobials implies the optimal selection of drug, dose and duration of antimicrobial treatment, along with a reduction in inappropriate and excessive use as a means of slowing the emergence of antimicrobial resistance. The proper use of antimicrobials depends on the knowledge of interrelationships between bacteria, antimicrobial, host and consumer. The antimicrobial groups most commonly used in poultry are the betalactams, polypeptides, aminoglycosides and aminocyclitols, macrolides and lincosamides, florfenicol, tetracyclines, sulphonamides, quinolones and fluoroquinolones and ionophores.
The use of antibiotic growth promoters (AGPs) in animal production began half a century ago, when Stokstad and Jukes added residues of chlortetracycline production to chicken feed. They were added with the objective to serve as a source of vitamin B12, but they caused a growth stimulation that was far too large to be explained only as a vitamin effect. ...

One of the landmark scientific achievements of 20st century has been the discovery of antibiotics. Antibiotics have redefined healthcare and for centuries now, have been helping doctors in saving precious human and animal lives. However, antibiotics have now become a victim of their own success. Due to their non-judicious and blind use, we are now facing a new dangerous healthcare challenge. The emergence of ‘superbugs’ or...

Introduction In North America, there has been a tremendous body of research in recent years to find the ideal product or program to replace or reduce the use of antibiotics in livestock and poultry production. This is driven by the legislation in the EU and the pressure the health-care system has placed on the use of sub-therapeutic levels of antibiotics for growth promotion. There have been many arguments made regarding...

More restrictions on antibiotic use in food animals are inevitable, and the search for alternatives has to take into account the integrity of both the upper and lower intestinal tracts. A shift in the understanding of where in the intestinal tract nutrients become available to the bird is important in devising an effective new antimicrobial strategy, said Dr....

Antimicrobial or antibiotic resistance is an emotive and often misunderstood topic. It is a subject that many, including governments, academics and consumers, use as a stick to beat our industry with! With this article we hope to give you a clearer picture of some of the issues involved and endeavour to look at the subject from a practical/field point of view rather than a theoretical/academic position.

Introduction
The trend to avoid using antimicrobial growth promoters in the feed has resulted in a more intensive search of alternative feed additives that have the ability of maintaining animal productivity while not affecting the quality of the end product. Among such alternatives, probiotics, prebiotics, symbiotics, organic acids, etc. Fuller (1989) defined a probiotic as a feed supplement...

One of our most effective strategies to combat bacterial infections is rapidly becoming ineffective: more and more bacteria are developing resistance against commonly used antibiotics. This is a worrysome development, that, though been recognized for decades, seems to have worsened lately. It is perceived that the speed of resistance development has overhauled the rate of developing alternative drugs. In attempts to stop...

Introduction Consumer safety is based on a series of measures including maximum residue limits and acceptable daily intakes as the most important ones. Acceptable daily intakes are determined in laboratory animals and extrapolated to humans through the application of safety factors. Thus, knowing how much of a particular food a human consumes daily, it is determined which is the maximum amount of a given chemical that may...
