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.

I have a doubt upon azithromycin use in poultry, that is as we know the half life of azithromycin is min 3days so should we consider the same half life in case of bird?or do we need to administer it like as it says on product 3-4days through water? anyone with good suggestion will be very helpful. ...

1. Introduction Antimicrobials are routinely used to treat clinical livestock diseases, as well as to control common disease events, or even as animal growth promoters [1]. Though the latter use is not allowed in many countries worldwide, in some still continue using them for prophylaxis and as growth promoters’ purposes [2,3]. Tetracyclines and sulfonamides are some of the most frequently used antimicrobial classes in animal production throughout the world [4]....

During COVID19 pandemic period, people all over the globe have understood the importance of protein consumption to boost up their immunity. Chicken meat and eggs provide a rich source of protein and known for the high digestible values which contains vitamins and minerals needed for improving overall health and immunity. It is estimated that 25% of the world's meat supply is derived from poultry, i.e. chicken, turkey, duck, geese, domesticated quail, etc. and increasing trend...

Introduction Poultry producers attempt to control infectious diseases through a variety of means, including appropriate farm management practices and breeding genetically resistant lines (Sartika et al. 2011; Scott et al. 2018). Unfortunately, existing farming conditions favour increased chicken densities in poultry houses, increasing the risk of spreading entero-pathogens such as Salmonella and Clostridium spp. (FAO 2013). For over half a century, veterinarians and poultry...

There is increasing pressure for the use of antibiotic growth promoters (AGPs) in poultry diets to be discontinued or reduced. In this context, the search for natural additives such as organic acids (OA) and essential oils (EO) has increased. Previous studies have reported beneficial effects on gut health of supplementing poultry diets with these natural feed additives. As in many countries the use of AGP is still allowed and the adoption of programs combining the effects of AGPs with feed...

Introduction The immune system of poultry is typically divided into innate responses and adaptive responses, and reviews of the avian immune system can be found elsewhere (Korver, 2012; Kogut, et al., 2020). Briefly, the innate response includes non-specific mechanisms of exclusion such as the skin and mucosal surfaces of the digestive tract, lungs and other organ systems with exposure to the outside world. Thus, one of the primary means of...

This study was done to investigate the viability of using organic acids as alternative replacement to antibiotics as in feed growth promoters and for use in managing broiler chickens in poultry farms around Nairobi in Kenya. The first part of this study was a survey and second part consisted of two feeding trials. The survey was conducted in the environs of Nairobi to determine the extent of antibiotic usage as a therapeutic agent and as a growth promoter....

Introduction Antimicrobial additives have been used since the 1950s and are an important alternative to allow adequate productivity for animals raised under increasingly intensive conditions. As a consequence of the widespread use and results of AGP in livestock production, there is interest in the study of these additives by meet industry and the academic community. A total of 68.200 publications are presented as results when using the words “broiler” and...

There are two schools of thoughts for treating a flock affected by viral diseases like IB, AI, ND & IBD. Some say we should immediately use antibiotic to counter any secondary bacterial infection in the process. And some say we should give just supportive & symptomatic therapy to flock in case of viral infection i.e bronchodilator, antipyretic, antioxidants/immunity modulators & liver tonics. I would like an opinion of some senior vets on this issue. ...

Background Antimicrobial resistance (AMR), is one of the biggest threats to food safety and considered a One-Health issue with the potential of spreading to other countries since resistant pathogens do not recognize boundaries [1, 2]. Recently, we have shown the transmission of AMR E. coli among chickens, humans, and the poultry environment [3, 4]. Globally, antimicrobial agents are used in food animal production to ensure good health and productivity of the animals [5–7]....

I. INTRODUCTION
Antimicrobial resistance (AMR) is considered one of the biggest threats to human and animal health today (Australian Government, 2015; O’Neill 2016) and all users of antimicrobial agents have a responsibility to ensure that these agents are only used when necessary.
The Australian poultry industry takes the issue of AMR very seriously and has a long history of developing and introducing initiatives to enhance infection prevention and...

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...
