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 The conversion of dietary protein and amino acids into the protein of chicken-meat is indeed a dynamic process. Quite typically, broiler chickens attain a live weight of 2.918 kg at 42 days post-hatch and a carcass weight of 2.151 kg following processing. This translates to 376 g of carcass protein as a Ross 308 broiler carcass contains 175 g/kg protein [1]. Broiler chickens consume 4.702 kg of feed over 42 days with dietary protein contents declining from 230 to...

1. Introduction Often a seemingly straightforward aspect of nutrition reveals itself to be, upon closer inspection, not so simple after all. An illustration of such a conundrum is the nutrition of the newly hatched broiler chick. Conceptualizing the different challenges faced by the hatchling and solving them should be remarkably simple, but the difficulty lies in the complexity in the development of the gastrointestinal tract (GIT), digestive physiology, immune system, and...

1. Introduction Effective functionality and health of the gastrointestinal tract (GIT) are important factors in determining animal performance [1]. These aspects are particularly relevant in poultry farming, where animals capable of growing rapidly within a short period of time are needed. Three components of gut health have previously been suggested: diet, mucosa (which is, in turn, characterized by the digestive epithelium, the gut-associated lymphoid tissue and the...

Digestive capability of young animals is different when compared to adult growing pigs and chickens. In this TechTalk, Ermin Magtagnob, Novus Technical Services Manager from Southeast Asia and Pacific, discusses how protease enzymes can assist in managing gut health problems associated with undigested proteins....

Copper is very useful for young animals’ gut health, particularly for the integrity of the small intestine. In this final Young Animal TechTalk, Matthew Bekker, Technical Services Manager for Novus Southeast Asia and Pacific, shares how copper in chelated form is highly valuable to chick’s and piglet’s epithelial cells and villous structure....

Early nutrition and feeding play a very important role to modulate the immature immune system of chicks and piglets. In this TechTalk, Teera Tiyasatkulkovit, Technical Services Manager for Novus Southeast Asia and Pacific, talks about how essential oils can complement the animal’s innate immune system and enhance their adaptive immune system to protect young animals and support their growth....

A feeding study was conducted to examine the efficacy of a synergistic blend of feed additives on growth performance, livability, gut integrity, immunity, caecal microflora and footpad health in broilers challenged with subclinical necrotic enteritis (NE). Additives were: A) synergistic blend of medium chain fatty acids (MCFA), slow-release C12, target release butyrates, organic acids (OA) and a phenolic compound; B) synergistic blend of partly buffered OA with MCFA; C) synergistic blend of...

1. Introduction Contamination of cereal grains and their byproducts by mycotoxins is a worldwide problem negatively affecting poultry production [1]. Two Fusarium mycotoxins which are among the most toxic and frequent feed contaminants are the trichothecene deoxynivalenol (DON) and fumonisins (FUM). DON is produced as a secondary metabolite by Fusarium graminearum and Fusarium culmorum, whereas FUM are secondary metabolites which are mainly produced by Fusarium verticillioides...

INTRODUCTION The poultry gastrointestinal tract (GIT) is home to a complex, dynamic, and variable bacterial-dominated microbiota (Zhu et al., 2002). This GIT microbiome variation may be explained by different host characteristics and environmental factors (Kers et al., 2018), including birds age (Ballou et al., 2016; Pedroso et al., 2016), sex (Torok et al., 2013; Zhao et al., 2013), type and breed (Videnska et al., 2014; Kim et al., 2015), and GIT regions (Yeoman et al., 2012)....

In many scientific publications, journals, articles, etc. reference is made to EUBIOSIS, but... What does this term refer to and why is it so important to be understood? Eubiosis is defined as the balance of the intestinal microbial ecosystem and is considered a fundamental concept in the field of human and animal health. The gut microbiota is a complex community of bacteria, fungi, viruses and protozoa located throughout the intestinal tract. A gut microbiota in a eubiotic state is...

INTRODUCTION The integrity of the gut is fundamental in birds as the mechanisms of digestion and absorption are inherent in the physiological metabolism of the gastrointestinal tract (GIT) and cannot be manipulated 1 . Numerous infectious and non-infectious agents can damage intestinal mucosa, as well as compromise digestion and absorption 2 . Among them, coccidia infections represent one of the most important enteric diseases. Coccidiosis is an infectious...

INTRODUCTION Necrotic enteritis (NE) is an enteric bacterial disease in chickens that is caused by Clostridium perfringens type G infection. Avian NE has gained much attention recently in the post antibiotic/anticoccidial agents' era as this infection has resulted in huge economic losses of 2 to 6 billion US dollars in the global poultry industry (Lee et al., 2020). Furthermore, the recently discovered NE B-like (NetB) toxin secreted by C. perfringens type G has been...
