Introduction Precision nutrition means diets are formulated as close as possible to requirements while avoiding any deficiency issues. Benefits of precision mineral nutrition can include reduced diet costs, reduced environmental impact, and reduced risk of toxicity. The major problem with precision mineral nutrition is increased risk of deficiency. Deficiency can be manifested as a clinical deficiency (e.g., grass tetany caused by inadequate magnesium), or as numerous subclinical...

The use of feed enzymes in monogastric nutrition has been a cornerstone of feed efficiency and environmental management for decades. However, a recent analysis suggests that the industry's long-held "scientific dogma" may be limiting the full potential of these additives. In an article on AB Vista's website titled "Enzymes through the ages: rethinking their use in animal nutrition," Mike Bedford (AB Vista) argues that the industry's focus on simple, measurable outcomes has created a...

I. INTRODUCTION Protease enzymes can improve the dietary protein utilization. Therefore, it is possible to decrease the level of dietary protein to save on feed cost while maintaining performance, reduce nitrogen excretion in the environment, and minimize the risk of enteric infections. The objective of this study was to evaluate the effect of a protease on performance and intestinal health of broiler chickens fed a standard diet or a low-density diet. II. MATERIALS AND...

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...

It has been demonstrated that the phosphorus (P) requirements of modern broilers are significantly lower than historical industry practice (Li et al., 2017). However, it is also apparent from these studies that the P requirement is dependent on the dietary calcium (Ca) concentration and whether the diet is supplemented with phytase. Most of the contemporary research has been conducted in the starter phase, but this feeding trial has been conducted in the finisher phase (days 22- 49) to...

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...
