Explore all the information onAntimicrobials 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. INTRODUCTION Non-therapeutic in-feed usage of antibiotics in animal diets has been implicated in development of antibiotic-resistant bacteria, some of which are zoonotic and pathogenic to humans (Stanton, 2013). Based on this fact, the European Union placed a ban on such usage of antibiotics 12 years ago (European commission, 2005; Castanon, 2007). However, the continuous incidence of antibiotic resistance in other regions is fueling the consideration and legislation of a global...

Meat and bone meal (MBM) is a valuable source of protein, calcium and available phosphorus for broiler diets (Anwar et al., 2016). The use of MBM in broiler diets at levels above 50 g/kg minimizes the need for inclusion of inorganic P, thus reducing feed cost. Potential indigestibility of protein in MBM (Kim et al., 2012) may act as a predisposing factor for necrotic enteritis (NE). Increased production of nitrogenous bacterial metabolites including amines and ammonia in the hindgut may...
1. Introduction Antimicrobial resistance (AMR) is a phenomenon where microorganisms develop resistance to specific antimicrobial agents, posing serious health risks [1]. According to conservative estimates, AMR is projected to be responsible for 10 million deaths annually by 2050 [2]. Currently, the European Union (EU) reports that over 670,000 infections are linked to AMR each year, resulting in nearly 33,000 deaths directly attributable to confirmed resistance [3]. Poultry...
1. Introduction Antimicrobials have revolutionized modern medicine by enabling effective treatments for many life-threatening diseases and saving countless lives. However, the emergence and spread of antimicrobial resistance (AMR) among pathogens has become a global health issue affecting humans, animals, and environment [1]. Recognizing AMR as a critical challenge, the World Health Organization (WHO) has emphasized the urgent need for concerted efforts to combat this growing threat...
Introduction Medication costs in the poultry industry (excluding vaccination costs) can account for up to 1% of the total production cost. This amount may not seem significant, however, when we talk about cash flow and investment from a business perspective, we can measure that it represents thousands of dollars, whose profitability often falls on the production unit manager and the person responsible for managing medications. In a layer hen business unit, for every 1 million layer...
The livestock industry is currently confronted with stringent regulations limiting the use of antibiotics, along with growing challenges from resistant pathogenic bacteria. These factors have prompted an urgent need to seek alternative strategies that can effectively promote animal health and optimize feed...

1. Introduction The surface of eggshells can be contaminated by bacteria such as Escherichia coli and Staphylococcus spp., which may account for 84% and 77% of the present Gram-negative and Gram-positive bacteria, respectively [1]. In addition to antibiotic resistance [1], Escherichia coli and Staphylococcus spp. (e.g., Staphylococcus aureus) may also be associated with the death of chicken embryos [2,3]. Eggs appear to be quite vulnerable to several threats, even biofilm...

Selective Elimination vs Competitive Exclusion: The Future of Antibiotic Alternatives in Food Animal Production As antimicrobial resistance (AMR) continues to threaten both public and animal health, the food animal industry is urgently shifting towards sustainable alternatives to antibiotics. Two promising strategies have emerged: Selective Elimination using bacteriophages or phage lysins and Competitive Exclusion using probiotics. Both methods target harmful bacteria but...

I. INTRODUCTION The meat chicken industry is growing rapidly as a result of an increasing population, relatively low production costs and excellent marketability with regards to affordability, sustainability and minimal religious restrictions. Poultry diets with lower crude protein (CP) have generated global interest from the meat chicken industry due to the benefits concluded by published literature. Low protein (LP) diets have been identified to lower feed costs, improve feed...
INTRODUCTION Foodborne infections caused by Salmonella enterica are of primary importance worldwide. The WHO estimates that Salmonella causes more than 153 million illnesses, 120,281 deaths, and 8.27 million disability-adjusted life years annually (1). As foodstuffs can be contaminated in several parts of the food chain, a “from farm to table” approach is necessary to understand the epidemiology of Salmonella. Although Salmonella can contaminate vegetables, food-producing...
Introduction: Using low-dose antibiotics as feed additives can enhance poultry and swine performance. However, such practices have led to bacterial resistance and antibiotic residues in animal-derived foods. Consequently, there has been a shift towards finding replacements for antibiotics as growth promoters (AGPs). Among the various alternatives, organic acids have emerged as a significant option. Acidifiers have gained attention as viable alternatives to antibiotics in poultry...
