I. INTRODUCTION Microbial enzymes are now routinely used in broiler chicken diets to reduce the effects of antinutritive factors (ANF) in feed and/or improve the digestion of nutrients (Bedford, 2011). There is a suite of enzymes that target ANF such as non-starch polysaccharides (NSP) and phytic acid as well as products which improve the digestion of nutrients such as protein and minerals. The major cereals used in poultry diets are wheat, maize, sorghum and barley. The objective of...

I. INTRODUCTION Low-protein diets for broiler chickens axiomatically contain high inclusions of supplemental amino acids and have the potential to generate economic, environmental and bird welfare advantages. Low-protein diets are usually formulated by reducing soybean meal inclusions and increasing inclusions of a range of supplemental amino acids. An alternative approach was adopted in the present study where dietary protein levels were reduced by the partial replacement of maize...

1. Introduction Intestinal health is a crucial parameter in ensuring the health of birds and the optimal use of nutrients because of its various functions, namely the digestion and absorption of nutrients, the secretion of mucins and immunoglobulins, and selective protection against pathogens [1]. This topic has gained even more interest in poultry production because of increasing demands for economic efficiency, animal welfare, food safety, reducing environmental impact, and...

INTRODUCTION Rabbits (Oryctolagus cuniculus) can receive high amounts of fibrous material in their diets, from 24.5% to 44.3% of neutral detergent insoluble fiber (NDF), so that they can take advantage of energy, protein, and vitamins from fermentative processes carried out by microorganisms in the cecum and the rest of the large intestine. This is how they manage to digest or ferment from 3% to 70% of the NDF, 0% to 82% of the hemicellulose, and 1% to 59% of the cellulose (De Blas...

1. Introduction Recent trends in food animal production emphasize reducing antibiotic use due to the growing threat of antimicrobial-resistant bacteria [1,2]. Consequently, there is a critical need for sustainable alternatives that promote growth and health while maintaining production efficiency. Phytobiotics are plant-derived compounds that have emerged as promising candidates for this role [3]. Unlike antibiotics, phytobiotics do not contribute to antimicrobial resistance or...

1. Introduction Weaning is recognized as a highly stressful period for young pigs, during which they experience maternal separation, new social and dietary conditions, and critical physiological changes. These stressors, often compounded by suboptimal sanitary conditions on farms, can lead to severe outbreaks of diarrhea, typically linked to the proliferation of specific pathogens. The most commonly implicated bacterial pathogen is Escherichia coli [1]. However, once dysbiosis and...

I. INTRODUCTION Modern broilers grow 5 times faster on 40% less feed than they did 60 years ago (Zuidhof et al., 2014). Because high body weight (BW) correlates negatively with reproduction and health (Decuypere et al., 2010), the severity of broiler breeder feed restriction increases every year relative to broiler growth potential. This intensifies competition for feed, resulting in unequal distribution of feed and poor flock uniformity. Achieving and maintaining high flock...

While the breeding programs of commercial meat chickens select birds with robust legs (Davis, 2015), poor leg strength and reduced locomotion are frequently observed in late stages of growth. We have previously reported that lower egg shell temperatures during early incubation, which delays chick hatch time, increases bone ash (BA) (Muir and Groves, 2017). Observations from our research and the literature (e.g. Ulmer-Franco et al., 2010) suggest that maternal breeder flock age may influence...

Growth promoting effects of zinc bacitracin, Bacillus-based probiotics and a blend of Yucca and Quillaja saponin in broilers have been well documented (Engberg et al. 2000; Cheeke, 2009; Jeong and Kim, 2014). These in-feed additives are commonly used in broiler diets but their effects at different dietary crude protein (CP) concentrations remain unclear. This study was conducted to study the effect of these additives when added to low and high-protein diets on performance and caecal...

Introduction Animal production relies on the supply of nutritious feeds supporting high growth, welfare and health of animals and the production of high-quality products in an environmentally sustainable and profitable manner. With feed cost representing 50 to 80% of the total production cost, feed manufacturers have a very important role in the overall economic viability of animal agriculture enterprises. Animal production involves a complex “nutritional supply...

I. INTRODUCTION NSP refer to a wide variety of polysaccharide molecules of cell walls with varying degrees of water solubility, size and structure. Their physiological functions are defined by whether they are water soluble or insoluble. The amount of soluble and insoluble NSP varies greatly among different ingredients; for example, corn and sorghum contain very low levels of NSP but wheat, rye and triticale contain high amounts of both soluble and insoluble NSP (Choct et al., 2010)....

1. Introduction It is well known that the major cost in poultry farming is feed, representing 70% of the total production costs [1]. In order to reduce this cost, the research has recently focused on exploring and evaluating new sources of raw materials from agricultural and industrial by-products for use as animal feed. Key benefits of this practice include lower dependence of animal production on human consumed seeds and reduced waste management costs [2]. Around 2.1 million tons...

1. Introduction The global population is projected to reach 9.7 billion by 2050, driving a significant increase in food and feed demand and the urgent need for alternative protein sources [1]. Currently, soybean meal is a crucial protein source in poultry and livestock diets due to its high-quality protein composition. However, sustainability concerns, including deforestation, monocropping, and biodiversity loss, as well as the environmental impacts of conventional crop systems such...

I. INTRODUCTION Non-therapeutic in-feed usage of antibiotics in animal diets has been implicated in development of antibiotic-resistant bacteria, some of which are zoonotic and pathogenic to humans (Stanton, 2013). Based on this fact, the European Union placed a ban on such usage of antibiotics 12 years ago (European commission, 2005; Castanon, 2007). However, the continuous incidence of antibiotic resistance in other regions is fueling the consideration and legislation of a global...

Every year the marketing age of broilers decreases by an average of 0.75 days for the same performance. This trend is likely to continue in the same direction for the coming years. Nutrition plays a vital role in enabling this improvement. As the feed cost represents an expensive input (~70-80% of broiler production cost), the poultry producer should be aware of the dynamics of the feed in its influence on final product quantity and quality. Formulating feed ideally requires in-depth...

In previous assays (Macelline et al., 2022), data on egg production rate (EP) and egg mass (EM) of Isa Brown layers from 27 to 33 weeks of age (peak production -PP) and from 42 to 48 weeks of age (Post PP) were used to predict amino acid (AA) requirements by fitting linear broken-line (LBL), and quadratic broken-line (QBL) models. Subsequently, the ideal ratios of Ile, Met + Cys, Thr, Trp, and Val relative to Lys for maximal EM and EP were determined. The current feeding study was...

I. INTRODUCTION Xylans and cellulose are the predominant fibre-polysaccharides in animal feeds, and xylanases, together with phytases, are the most widely used supplemental microbial enzymes in feeds. Proteinaceous xylanase inhibitors (XI), primarily attributed to three types, Triticum aestivum xylanase inhibitor (TAXI), xylanase inhibiting protein (XIP) and thaumatin-like xylanase inhibitors (TLXI), are found in a wide range of plant feedstuffs, particularly cereals grains such as...

I. AMINO ACIDS: TOWARDS MORE PRECISE FORMULATION Dietary protein reduction in swine or poultry is driven by economic, environmental and societal issues - the three pillars of sustainability. Formulating on the basis of each indispensable amino acid (IAA) instead of a minimum crude protein (CP) level allows a reduction in feed cost, a decreased dependency on imported soybean meal, and a lower pressure on animal health. In addition, the increasing availability of feed grade amino acids...
