Poultry nutrition - Other additives
Alternative feed additives have promising importance in broiler production due to the ban on the use of certain antibiotics. The most used antibiotic alternatives in broiler production are phytogenics, organic acids, prebiotics, probiotics, enzymes, and their derivatives. Antibiotic alternatives have been reported to increase feed intake, stimulate digestion, improve feed efficiency, increase growth performance, and reduce the incidence of diseases by modulating the intestinal microbiota and immune system, inhibiting pathogens, and improving intestinal integrity. Simply, the gut microbiota is the target to raise the health benefits and growth-promoting effects of feed additives on broilers. Therefore, naturally available feed additives are promising antibiotic alternatives for broilers.
I. Introduction Salmonella spp. in poultry pose a serious risk for food safety. The complex nature of Salmonella infections in poultry requires a multifactorial solution. It is key to preventing Salmonella colonization throughout the entire gastrointestinal tract (GIT). Short chain fatty acids (SCFA) have been described as having beneficial effects in the upper part of the gut, whereas medium chain fatty acids (MCFA) target the lower GIT (Van Immerseel et al., 2009). Coated butyrate...

INTRODUCTION Consumer preferences are leading to changes throughout the poultry industry (Northcutt and Jones, 2004; Fanatico et al., 2005; Meneses et al., 2017). From 2016 to 2017 the amount of organic poultry production has increased by 76%, holding a 2016 market share of $750 million (Philips, 2017). This is compared to an increase of the total organic agricultural farming market share which rose only 23% (Philips, 2017). This is partially influenced by consumers believing the...

An experiment was conducted to assess the potential for guanidinoacetic acid (GAA) to spare dietary energy and influence muscle myopathies when included in broiler diets. A total of 1,056 male Ross 708 broiler chicks were randomly assigned to 48 floor pens with 22 chicks per pen. Broilers were fed one of four experimental diets and reared to 50 days of age. Dietary treatments consisted of a control (T1), T2 (T1 – 110 kcal/kg apparent MEn), T3 (T2 + 0.08% GAA), and T4 (T1 – 55...

1 | INTRODUCTION Due to the impact of climatic changes and other global events such as conflict, the Covid‐19 pandemic, recession, and supply chain issues, conventional feed ingredient prices are continually increasing. The effect of these constraints is felt largely in developing countries that are coming under huge pressure to source raw materials such as corn and soybean meal (Abro et al., 2020). The search for alternative feed ingredients to sustain the livestock...

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 In recent years, the poultry sector has been developing rapidly worldwide to meet the growing consumer demand for poultry meat and eggs. Chicken meat is low in saturated fat and rich in protein, vitamins and minerals [1]. Similarly, a hen’s egg is the most affordable source of animal protein and constitutes a complete and highly nutritious food with significant health benefits for consumers [2]. It is estimated that animal-based food demand will grow by...

1. Introduction The availability of good quality quail eggs to consumers depends on the degree of deteriorative impacts they have suffered before being offered for sale. This degree of deterioration will be determined by the management of the eggs, which mainly includes the environmental conditions to which they are subjected, whereby the degree of internal deterioration of eggs is lower in cool compared to hot environments [1,2]. However, these cool environments will only be fully...

There is increasing evidence that supplementing small amounts of prebiotic xylo-oligosaccharides (XOS) into poultry diets has positive effects on bird performance and gastrointestinal health. Soluble XOS that reach the caeca intact are utilised by beneficial bacteria, inducing positive effects such as increased production of short chain fatty acids (Aachary & Prapulla, 2011). Commercial endo-xylanases are added to diets to reduce digesta viscosity, but have the side effect of producing...

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...
