Poultry gut health
The efficient conversion of feed into its basic components for optimal nutrient absorption is vital for both broiler and broiler breeder production and welfare. Gut health, an intricate and complex area combining nutrition, microbiology, immunology and physiology, has a key role to play. When gut health is compromised, digestion and nutrient absorption are affected which, in turn, can have a detrimental effect on feed conversion leading to economic loss and a greater susceptibility to disease. In addition, recent changes in legislation on the use of antimicrobials, differing feed requirements and more efficient birds highlight the need for a better understanding of gut function and gut health.
1. Introduction Gut microbiota, represented by bacteria, archaea, viruses, and eukaryotes, take part in regulating several functions in both humans and animals [1]. It has been estimated that the chicken gut can be colonized by at least 1000 different microbial strains that are involved in maintaining the intestinal health of hens while sustaining productivity and growth [2,3]. This microbiota takes part in various metabolic pathways related to nutrient digestion and absorption,...

I.INTRODUCTION Both overheating and underheating affect the nutritional value and quality of SB (Karr-Lilienthal et al., 2004). Undercooked SB results in an excessive concentration of antinutritional factors, such as TI, decreasing the intestinal activity of pancreatic proteases. In contrast, excessive heat treatment results in a Maillard reaction that reduces nutrient digestibility (Araba and Dale, 1990). Thus, the objective of this study was to investigate the contributions of...

Probiotics are included in the feed and administered continuously during the entire production cycle to maintain intestinal integrity and strengthen the immunity of the bird, thus reducing the need for repeated medication. Alternatively, water-soluble probiotics are often applied to quickly react to upcoming stress situations in the flock – but they can negatively impact the formation of biofilm in the water lines. For this reason, formulations that reduce the formation of biofilms...

1. Introduction In intensive broiler production, the objective is to obtain high-performance productivity at a low cost. To accomplish production goals and satisfy the increased demand for poultry meat worldwide, intense genetic selection, health, management, and nutrition programs have emerged (Peralta et al., 2016). As a major development priority for nutrition, researchers are looking for natural additives to replace antibiotic growth promoters (AGPs). The AGPs were banned since...

INTRODUCTION Since the use of antibiotic growth promoters was banned by the EU on January 1st, 2006, several feed additives have been studied as alternatives to antibiotics, such as probiotics, prebiotics, synbiotics, and herbal medicines (1). Among these feed additives, prebiotics have been studied and supplemented broadly into broiler diets in recent years. Gibson and Roberfroid (2) defined a prebiotic compound as a non-digestible food ingredient utilized by intestinal microbiota....

Introduction The chicken gastrointestinal tract (GIT) harbors a very diverse microbiota, dominated by Bacteria, that influences health and growth performance of chicken. A healthy microbiota provides nutrients to the host and promotes competitive exclusion [1]. The composition of the GIT microbiota differs according to diet, age and genotype of hosts as well as the portion of the intestinal tract, among others [2]). The poultry industry has adopted the use of dietary additives...

Ioannis Mavromichalis, a Ph.D. consultant in the animal nutrition industry, mentioned in Feed Strategy, "In my experience, feed prices always fluctuate. When they rise, the most effective way to maintain profitability is by enhancing the feed conversion ratio, or FCR." The Feed Conversion Ratio (FCR) is crucial in livestock farming as it significantly affects the cost per kilogram of meat. Feed costs can account for 40% to 70% of total production expenses, varying by country and type...

I. INTRODUCTION The increased recognition of antimicrobial resistance as a public health risk and, therefore, the imposed restrictions on the use of antimicrobial growth promoters (AGP), has driven the search for novel nutritional strategies for broiler chickens. The advances in molecular biology, analytics, and data science in the past years have enhanced our understating of the gastrointestinal tract (GIT) microbiome of chickens (Oakley et al., 2014; Sun et al., 2021). These novel...

I. INTRODUCTION Mycotoxins are secondary metabolites produced by fungi (fusarium, aspergillus, penicillium mainly) that can cause serious health problems in poultry and may result in severe economic losses. They can exert negative impact on both performance (Kolawole et al, 2020) and intestinal health (Antonissen et al, 2014) depending on the type of mycotoxin, extent of exposure, its concentration, the age of the animals and their health status. Mycotoxins can also be a predisposing...
