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.
INTRODUCTION Supplementing poultry feed with specific enzymes improves the nutritional value of feed ingredients by increasing the efficiency of digestion and nutrient uptake. These enzymes help to increase the availability of nutrients particularly starch, protein, amino acids and minerals such as phosphorus and calcium from feed ingredients. Variability in the nutrient content of maize has been demonstrated to be as great as that observed for wheat and barley...

1. Introduction Poultry meat is considered a healthy source of high-quality protein, vitamins, minerals and essential polyunsaturated fatty acids (PUFAs), especially the omega (n)-3 fatty acids [1], and still remains one of the cheapest sources of protein [2]. The OECD-FAO agriculture outlook 2016–2025 forecasts an expansion of meat production by 1.8 Mt annually by 2025, mainly due to pork and poultry products [2]. Moreover, the poultry sector is possibly the fastest...

Introduction Butyrate plays an important role in gastrointestinal health in broilers. Although very efficacious and possible to substitute for dietary antibiotics, pure butyrate has obvious limitations of smell and handling and is virtually absorbed in the upper digestive tract. Butyrate glycerides have no such limitations and their butyrate can be released by lipase in the small intestine, thus providing a novel delivery system to the chicken gut. In our previous...

Most of our customer relationships begin with a unique application challenge, and this case was no exception. An internist at a Midwestern medical hospital contacted us to discuss how our technology might be applied to reduce the use of antibiotics in monogastric animals; his concept was to deliver a blend of organic acids into the intestines to target harmful bacteria instead – essentially pioneering a solution to the growing problem of antibiotic resistance in animals and in...

1. Introduction Small-scale poultry production is a very common practice in rural households around the world, and several studies have evidenced that these production systems have played and continue to play an important domestic socio-economic role in many poor rural households [1,2]. Backyard poultry production systems (BPS) are the most popular systems within small-scale poultry production, where animals are usually kept without proper disease prevention or control...

1. Introduction Antimicrobial drugs have a prominent role within the veterinary and animal sciences as they have been used not only for therapeutic and preventive purposes, but also as growth promoters [1]. Although the European Union has banned the latter practice, it is unfortunately still common in other countries [2,3]. Tetracyclines are the main antimicrobial drugs currently in use for veterinary purposes. Sulfonamides and macrolides are the next most common...

The average commercial broiler consumes 3.2 kg of feed over 35 days to achieve 1.8 kg of body weight, compared with more than 20 kg of feed over 112 days to attain the same weight in the 1920’s. This improvement in poultry growth performance has been achieved, in large part, through advances in animal genetics, health, and nutrition, including the use of in-feed antibiotic growth promoters such as virginiamycin and bacitracin methylene disalicylate. Dietary antibiotics have been used...

INTRODUCTION Antimicrobial resistance (AMR) has become a major threat for public health worldwide (WHO, 2014). One of the main factors contributing to the emergence of resistant bacteria has been the massive use of antimicrobials for growth promotion and disease prevention for several years in animal production (Guo et al., 2018; Mehdi et al., 2018). However, although nowadays the use of antibiotics in poultry is a controlled practice (ESVAC, 2017), different studies...

1. Introduction Avoiding contamination is one of the greatest challenges in meat hygiene practice to prolong the shelf-life of meat and prevent food poisoning of consumer. A substantial microbial reduction of potentially contaminated fresh poultry can be achieved by decontamination with chlorines, acid and alkaline solutions. Besides general hygienic measures during the slaughter process sodium hypochlorite, lactic acid and trisodium phosphate (TSP) seemed to be the most...

Antimicrobial resistance (AMR) is a global human and animal health concern, which is influenced by the use of antimicrobial agents in human and veterinary medicine, and the plant sector as recognised at the highest political level by the UN General Assembly resolution 71/3, adopted in 2016. To combat antimicrobial resistance, the World Organisation for Animal health (OIE) develops science-based intergovernmental standards and guidelines covering terrestrial and aquatic animals. ...

Antimicrobial resistance is one of the top public health problems worldwide. Especially concerning is the loss of effective antibiotics for bacterial infections that were previously highly effective and led to major advances in human health. Continued exposure to existing classes of antibiotics with few new classes emerging, coupled with failure of pharmaceutical companies to recoup return on investment relative to other classes of drugs for use in modern medicine have created a complicated...

Dietary antibiotics have been used in the food animal industry for more than 60 years, not only to control infectious diseases, but also to increase feed efficiency and improve growth performance. In chickens, subtherapeutic, in-feed antibiotics can increase body weight gain up to 8% and decrease the feed conversion ratio (feed intake/body weight gain) up to 5%, both compared with an antibiotic-free diet. Antibiotics overuse and abuse on a global scale have led to the emergence of multi-drug...
