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 Enzymes have been developed as feed additives to improve the digestion and absorption of nutrients. The first phytase products entered the market in 1991 and have since been used extensively in monogastrics. Supplementation with exogenous phytases in cereal vegetable-based diets has been shown to improve monogastric animal production and can also contribute to breaking down phytates. This reduces phosphorus contamination and improves the utilization of phytic...

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...

Abstract: Ruminants are those animals, who perform rumination or regurgitation of food. In every feed, nutrients are contained in the form of carbohydrates, proteins, fats, minerals and vitamins. Being a trace nutrient component, sometime livestock owner avoids to supplement the animal feed with these substances. Since ruminants possess rumen and ruminal microorganisms are capable of synthesizing water-soluble vitamins and vitamin-K. Therefore, only vitamin-A, D and E are considered to be...

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...

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...

During the perinatal period (within three weeks postpartum), dairy cows are in a state of negative energy balance, with fat tissue breaking down and a large amount of non-esterified fatty acids (NEFA) flowing into the liver. Moderate lipolysis and a moderate release of NEFA are beneficial for cows to successfully cope with negative energy balance, but excessive lipolysis leads to high concentrations of NEFA flowing into the liver beyond the ability of liver cells to oxidize fatty acids for...

I. INTRODUCTION Exogenous feed enzymes were first introduced as commercially-relevant feed additives in the 1980s with an initial focus on reduction of the antinutritional effects of high molecular weight soluble pentosans in wheat- and barley-based diets for young broiler chickens (Bedford & Partridge, 2010). Exogenous phytase was launched in the early 1990s to increase the digestibility of organic phosphorus and to reduce the antinutritional effects of phytic acid (Selle &...

Measures to improve bird performance have been sought due to the imminent phase out of in-feed antibiotics in poultry and continued demand for higher poultry feeding efficiency. Promotion of gizzard development by physical structure of feed ingredients or addition of dietary fibre is one such strategy with the hypothesis that larger ingredient particles and higher fibre enhance digestive enzyme secretion and feed efficiency in broilers (Kheravii et al., 2017; and Svihus, 2011). This study...

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...
