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.
Introduction Poultry scientists have long discussed and debated how the energy values of feed ingredients should be expressed (Zuidhof 2019). Pesti (2024) suggested that it is time for a paradigm shift in the way feed ingredient nutrient contents are described, and labeled the new categories collectively the Armidale method (see Fig. 1 for examples). He also proposed expanding the net energy (NE) to NEATP, based on the production of adenosine triphosphate (ATP) system of...

Juan José Mallo, Technical and Commercial Director at Norel, explains how the company is helping nutritionists increase phosphorus release in animal diets. By reducing calcium–phytate complex formation and introducing calcium pidolate, a 100% available organic calcium source, it’s possible to unlock more phosphorus from plant ingredients while maintaining adequate calcium levels. ...

I. INTRODUCTION Coccidiosis is one of the main disease challenges affecting broiler production worldwide. This disease has a significant economic impact on the poultry industry and the global cost of coccidiosis in chickens linked to prevention, treatment, and performance losses is estimated at US$13 billion or US$0.20 per bird (Blake et al., 2020). Coccidiosis is caused by protozoan parasites of the genus Eimeria. Seven different Eimeria species are known to affect chickens, each...

I. INTRODUCTION The emergence of zoonoses, antimicrobial resistance, and more recently pandemics, has led to a rapid escalation of society demands regarding animal production and consumption. In addition to conventional practices like the genetic selection and vaccination strategies, numerous emerging solutions such as the supplementation of probiotics or short chain fatty acids in animal feed are being pursued to enhance animal health and resilience to disease. The glyceride of...

1. Introduction Poultry is the most consumed animal protein source in the world, and the trend is expected to continue increasing [1]. The world population reached 8 billion in 2022, and is likely to reach 9 billion in 2037 [2], which will continue to increase pressure on the global chicken-meat industry. One way to meet this increasing demand is to improve the efficiency of chicken-meat production. Precision nutrition is a strategy to improve growth efficiency, reducing the...

I. INTRODUCTION Sustainability comprises three principal components: the environment (demand for resources and potential for environmental pollution), ethical issues (welfare of man and his animals), and economic robustness (FAO, 2012). At first glance, insect protein is a sustainable alternative to traditional protein sources such as soybean meal. Insect production requires less land, water and other resources than traditional protein sources, and they can be raised on...

In Australia, 35 million tonnes of sugarcane are harvested annually which produces approx. 10 million tonnes of a by-product called bagasse. Sugarcane bagasse is an insoluble fibre source and recent studies in broilers indicated that bagasse can be added at 2% in both normal and reduced protein (RP) diets to improve FCR by 2-3 points and weight gain by 30-40 g (Sharma et al., 2021a,b). Thus, sugarcane bagasse may be a novel insoluble fibre source for poultry. Follow-up studies were conducted...

Numerous liver diseases originate from prior alterations in the intestinal barrier and the gut microbiota. The gut-liver axis has an anatomical and immunological connection that makes the liver the first organ exposed to everything that crosses the intestinal barrier. The intestinal mucosa constitutes the body's most important biological barrier. In addition to absorbing nutrients, it acts as a defense structure capable of preventing the passage of microorganisms, endotoxins,...

Introduction The poultry industry plays a vital role in global food security, providing an affordable and efficient source of animal protein (Castro et al., 2023). However, maintaining flock health and productivity remains a major challenge, with intestinal health playing a central role in poultry performance (Korver, 2023). With the rise of antibiotic resistance across the globe, the potential restriction of in-feed antibiotic growth promoters (AGPs) in animal food production could...

Nutritional factors of gut inflammation (D. Korver) The intestinal tract is one of the largest, if not the largest, surface areas exposed to the environment of humans and poultry (Ferrer et al., 2003; Helander and Fandriks, 2014). Although the digestive tract is contained within the body, the lumen is actually outside of the bird. Therefore, although the function of the intestinal tract is usually thought of as being the uptake of nutrients, it has another important function:...

INTRODUCTION There is an increasing demand for animal-based protein to meet the nutritional needs of the ever-increasing global population. The protein obtained from broiler meat is one of the most promising animal-sourced proteins, considering its quality and affordability. To contribute to the supply of animal-based protein, fastgrowing broiler strains have been developed for higher muscle yield in a short period. However, broiler’s faster growth in a limited time results in...

INTRODUCTION Reducing the production cost of quality meat and eggs for the ever-growing world population is a prime target of the poultry industry. Conventional feed ingredients like corn and soybean meal are widely used in broiler feeding programs, which increase the competition among food and feed and lead to raise production costs (Donohue and Cunningham, 2009; Stefanello et al., 2016). Several strategies were attempted to minimize the cost per unit production, such as...

INTRODUCTION The world’s population is growing exponentially, causing a rise in demand for animal-based protein. To meet the meat demand, broiler chickens have been genetically selected for higher feed efficiency and high muscle yield. As a result, these broiler chickens produce a high amount of metabolic body heat and are highly susceptible to heat stress (HS), especially during the summer. Moreover, chickens lack sweat glands and have feather covers, which make them extremely...

INTRODUCTION To maximize the profitability of the broiler breeder production chain, it is necessary to increase egg production and hatching rates to obtain more viable offspring. The inclusion of substances with antioxidant properties in the diet of broiler breeders aids the enzymatic defense system in controlling the damage caused by free radicals in cells. Carotenoids are an example of this type of substance because they have antioxidant, pigmenting, provitaminic and...

DESCRIPTION OF PROBLEM There are growing concerns that the continual feeding of inorganic P is leading to the development of eutrophication of surface waters. Excessive P runoff from soil causes an accumulation of P in water sources, and this can result in toxic algal blooms and fish kills [1]. The availability of P from feedstuffs of plant origin is low for poultry because a greater proportion of the total P is present in the phytate form, a form that has low availability...

Essential oils (EOs) are secondary plant metabolites, some of which can stimulate feed intake, and digestion. The capacity of the small intestine to digest and absorb nutrients early in the life of the chick depends on an adequate embryonic development of the villi and crypts and overall, the integrity and functional properties of the epithelia, including the expression and abundance of digestive enzymes and nutrient sensors and transporters. Some key transporters include the sodium-glucose...
