Phytogenics in poultry nutrition
Phytogenics, also known as phytobiotics, are natural bioactive compounds of botanical origin that are used as alternatives to antibiotic growth promoters (AGPs) and are added to feed to enhance animal performance. Although phytogenics encompass a wide variety of substances of biological origin, formulation, chemical characterization, and purity, they can be classified into four groups: (1) herbs (products obtained from flowering, woody, and nonperennial plants); (2) botanicals (whole or processed parts of a plant, such as roots, leaves, tree bark, and spices); (3) essential oils (hydro-distilled extracts of volatile plant compounds); and (4) oleoresins (anhydrous solvent-based extracts). These plant-derived products do not contain residues, are natural, and are less toxic than synthetic antibiotics or inorganic chemicals. Many are generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) and can be used as feed additives in animal nutrition.
1. Introduction Antimicrobial resistance (AMR) is one of the main global threats today, and recent reports estimate that it directly caused 1.27 million deaths in 2019 [1]. In Brazil, the National Health Surveillance Agency, through the Evaluation of National Indicators of Health Care-Related Infections (HAIs) and Microbial Resistance (MR), in the year 2021, estimated that Escherichia coli resistance to different classes of beta-lactams can reach rates of 47.5% to cephalosporins,...

One Health Mission For most of the 20 th century, society viewed veterinary medicine primarily as an animal health medical discipline. In recent years, highly publicized public health threats have helped many realize the fundamental linkages between veterinary medicine and human health. According to the World Health Organization (WHO), one or more new infectious diseases have emerged each year since the 1970s (WHO 2007). The majority of these have been zoonoses,...

INTRODUCTION The initial stage of a laying hen's life is crucial for its development. During this period, optimal nutrition is essential for ensuring strong performance and high egg quality throughout the hen's productive lifespan (Rentsch et al., 2023). During this phase, young laying hens undergo significant physiological changes, including the development of reproductive organs and the initiation of egg production. Adequate nutrition during this period is crucial for...

I. INTRODUCTION Phytogenic products are used as an antibiotic alternative, with other alternatives like prebiotics, probiotics, organic acids and other products with antimicrobial properties. The ability of phytogens to reduce the load of significant pathogens such as Clostridium (2020), Escherichia (Zou et al., 2016), and Salmonella (Abudabos et al., 2016), and improve the health and performance of chickens makes them increasingly popular. Phytogens also improve critical layer...

The extraction of plant oils from crops results in so-called “waste” products that can be repurposed as protein sources for animal agriculture, supporting the development of a circular economy and the world’s bio-economy sector.
In the Mediterranean region (as well as similar climates), the production of olive oil has increased, leading to large quantities of olive oil byproducts that may be suitable ingredients for poultry rations, according to a review article...

Dietary alfalfa may improve broiler growth, but fiber inclusion may be detrimental during coccidiosis challenge.
Alfalfa is a source of health-promoting bioactive compounds (phytochemicals) that may offer several benefits to the poultry industry by direct action or by influencing the microbial communities in chickens.

Functional foods can be defined as foods containing bioactives that provide health benefits beyond basic nutrition. Substantial research has examined phytochemical bioactives; however, there is also interest in bioactives from animals. Functional foods of animal origin are due to the bioactives present in foods such as eggs, dairy, meat and fish. This presentation will introduce and overview the concept of functional foods and outline the uniqueness of animals as a source of bioactives for...

I. INTRODUCTION Necrotic enteritis (NE) in broiler chickens is an economically important disease which can be controlled by antibiotics (Timbermont, et al., 2011). The occurrence of necrotic lesions in the small intestine is associated with proliferation of Clostridium perfringens, which leads to lower growth rate in subclinically infected chickens. Increasing concerns regarding antibiotic resistance and the presence of drug residues in animal products have led many countries to ban...
