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...

Purpose The following article is a primer on least-cost formulation. While explaining the fundamentals of least-cost formulation, the author also goes over more advanced features such as shadow prices, price maps and nutrient factoring. This is a must-read for those who want a concise introduction to least-cost formulation. In the not so distant past, feed manufacturers used to balance their feeds using hand calculations and often relied on tedious...

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. INTRODUCTION Supplementation of amino acids to reduce feather pecking behaviour and improve plumage condition has been previously studied and found to be successful (Savory, 1998, van Hierden et al., 2004). Feather eating behaviour performed by feather pecking birds suggests that feathers (predominately composed of keratin protein) may be consumed as an alternative source of amino acids, if digested. Methionine is an essential amino acid required for egg production and...

1. Introduction Chickens have a well-developed trichromatic vision system composed of diverse photoreceptors and cones [1], allowing them to perceive a broad range of the color spectrum [2]. Chickens can see in ultraviolet wavelengths and perceive colors that are not visible to most mammals [3], including humans [4]. The chickens’ sharp visual capabilities allow them to effectively survey their surroundings and localize feed [5,6]. In addition, broiler chickens have shown...

Introduction Fish or any animal needs an adequate balanced diet that contains all the required necessary essential nutrients to have optimal growth. These nutrient requirements vary from species to species, sex, age, the environment where it lives, different stages of larval development, and the health status of the species. A minimum of 35 to 45 nutrients is required for marine fish. To have the best optimal growth and reduce pollution in the environment a thorough knowledge of...

Introduction The great majority of the main oilseed and cereals crops globally are grown to satisfy food demand, including a sizeable indirect component via consumption of meat and other animal products. Since the 2000s the advent of biofuels has added a variable but significant component to this equation. The first biofuels wave in the 2000s had a rocky trajectory due to associated food price spikes in 2011 and the ‘food versus fuel’ controversy. Today, governments...

Introduction Animal husbandry, the agricultural practice of breeding and raising livestock, is a major food-producing industry worldwide. The increasing global demand for animal protein results in rapidly growing animal production as well as the growth of animal feed and the feed additive market. The feed additives have played a significant role in the sustainability of the livestock industry. There are four major drivers for the growth of the animal feed additive market including:...

Introduction The dairy industry continues to provide a nutritious food source to our growing global population. Throughout history this industry has undergone significant evolutions contributing to a “more sustainable” product. But what does sustainability really mean, and in animal agriculture, why do we care? According to the U.S. National Environmental Policy Act (NEPA) of 1969 sustainability is to “create and maintain conditions, under which humans and nature...
