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.

In recent years protein feed ingredients are consistently increasing in cost and protein in poultry diets has become one of the most expensive nutrient. Urbanization is putting pressure to produce more and high quality protein sources in less space. Neutralizing substandard quality feed ingredients with effective tools has also become a new concern. In parallel people are more concerned on impact of animal agriculture on environmental pollution. Hence research has focused in the direction to...

I. Introduction Feed is the largest cost in poultry production, particularly in recent times due to the increased price of protein and energy sources. Feed cost can be reduced with the inclusion of alternate protein and energy sources like pearl millet, deoiled rice bran (DORB), meat and bone meal (MBM), dried distillers’ grains with solubles (DDGS) and mustard deoiled cake (MDOC) replacing soya bean meal (SBM) and corn. However, these alternate ingredients have low...

I. Introduction Plant-derived isoquinoline alkaloids (IQ) have the potential to support gut integrity and growth performance under conditions of enhanced stress such as heat stress. The previous study revealed that the BW increased in the IQ group, and the level of FITC-d, to evaluate the gut barrier function, reduced in the IQ supplement group (Kitasato et al., 2021). However, a comprehensive study on the effect of IQ on growth performance and gut integrity under heat stress during...

The increasing prices of major feed ingredients have prompted animal nutritionists to use inexpensive raw materials in their diet formulations to lower feed cost. However, due to their relatively lower digestibility, diets formulated with these raw materials often lead to poor gut health status and animal performance. For instance, poor protein digestibility results in the formation of toxic metabolites that can impair gut health and subsequently confer negative effects on broiler...

1. Introduction The health of the gastrointestinal tract is one of the important indicators of the overall health of an organism. The health of the intestine is given considerable attention in human nutrition due to the existence of various autoimmune and other diseases. Intestinal epithelial barrier dysfunction and increased permeability result in a “leaky gut”, which is associated with intestinal disorders in humans, such as inflammatory bowel disease (IBD), bowel...

We know that young geese benefit from warmer drinking water, but what is the optimal water temperature? Poultry scientists take a closer look
A new investigation into goose health suggests providing drinking water that is at least 18? (64.4?) may boost the activity of digestive enzymes, promote intestinal development, increase water consumption, and even increase goose eye temperature. Based on their findings, the...

INTRODUCTION It is imperative to identify factors that inhibit the digestibility of nutrients for successful commercial poultry production. The non-starch polysaccharides (NSP) like substances of hemicellulose, cellulose, and pectin can reduce nutrient digestibility in poultry (Choct, 1999). Among the NSP, β-mannans are a group of hemicelluloses, which are present in many ingredients used for poultry feeds like soybean and other leguminous seeds. It occurs in the forms of...

I. Introduction Phytase, apart from increasing phosphorus (P) availability from plant ingredients, improves availability of non-P nutrients like Ca, amino acids (AA), and energy (AME) by facilitating the breakdown of phytate P and thus negating its antinutritional effects (Dersjant-Li et al. 2016). Phytase along with carbohydrase enzymes could improve productivity of chickens with a lower feed cost when proper downspec (reduction of nutrient levels in the diet) is applied. It is...

INTRODUCTION Finding effective strategies to improve chicken’s feed efficiency (FE) is a major goal to decrease overall production costs, preserve additional edible resources for humans, and reduce the ecological footprint of chicken rearing systems (Bottje and Carstens, 2009; Yan et al., 2017). Chickens of divergent FE differ in several phenotypic characteristics with the most obvious difference being the lower feed intake of high feed-efficient chickens compared to low...

BACKGROUND The momentum of scientific paper publication toward mycotoxin is an increasing trend where 16,821 papers were recorded in Scopus since the first mycotoxin, aflatoxin (AF) was identified in the year 1965. Data clearly showed the significance of mycotoxin research which will be further discussed later in this review paper. Nevertheless, the global health issue arose from mycotoxin is still frequently ignored in many low-income countries, where mycotoxins affect staple...

The intersection of ancient wisdom and modern science is propelling a substantial leap towards profitability and sustainability in poultry production. Ayurveda, the time-honored system of holistic health, has paved the way for evidence-based approaches that align harmoniously with our environment. It places a strong emphasis on disease prevention and overall well-being, offering a balanced approach to livestock care that synergizes conventional and natural medicine. Ayurveda's wisdom...

1. Introduction The global demand for chicken-meat is increasing. Globally, poultry meat is expected to represent 41% of all the protein from meat sources in 2030 and exceed the 34% share for pig meat, 20% for beef and 5% for sheep meat [1]. In Australia, the 46.9 kg per capita chicken-meat consumption in 2021/22 is clearly superior to pork (27.7 kg), beef (19.1 kg) and lamb (5.5 kg) with a 47.3% market share [2]. To meet this high consumption, Australian broiler operations processed...

1. Introduction Coccidiosis is a major enteric infection of poultry that is estimated to cost more than USD 14.5 billion annual losses globally [1]. Although coccidiosis control using various anticoccidial chemicals, such as ionophores, coccidiocides, and coccidiostats, has long been a mainstream strategy in modern poultry production, alternative control strategies to antibiotics are necessary owing to the antibiotic ban [2]. Therefore, much effort has been made to develop...

Optimal soybean (SB) processing conditions is essential to ensure that antinutritional factors as trypsin inhibitors are deactivated while maintaining protein solubility and dispersibility. Heat processing is critical for improving amino acid digestibility of extruded SB for broilers. Excessive heat treatment can lead to denaturation of proteins, resulting in a negative impact on animal performance and microbiota composition. In this study, we investigated the effect of three different...
