Swine nutrition
Pigs require a number of essential nutrients to meet their needs for maintenance, growth, reproduction, lactation, and other functions. However, factors such as genetic variation, environment, availability of nutrients in feedstuffs, disease levels, and other stressors may increase the needed level of some nutrients for optimal performance and reproduction.
Swine require six general classes of nutrients: water, carbohydrates, fats, protein (amino acids), minerals, and vitamins. Energy, although not a specific nutrient, is an important nutritional component and is primarily derived from the oxidation of carbohydrates and fats. In addition, amino acids (from protein) that exceed the animal’s requirements for maintenance and tissue protein synthesis provide energy when their carbon skeletons are oxidized. Antibiotics, chemotherapeutic agents, microbial supplements (prebiotics and probiotics), enzymes, and other feed additives are often added to swine diets to increase the rate and efficiency of gain, to improve digestibility, and for other purposes, but they are not considered nutrients.
Pigs require a more concentrated diet and should be fed a less-fibrous feed than cattle, sheep, or horses. As they grow, their nutritional requirements change and the diet should meet their needs in various phases of growth and stages of production.
1. Introduction Combining different feedstuffs to formulate swine diets is essential for the supply of amino acids (AA), energy, and other nutrients necessary for optimal growth and nutrient utilization and production. While the main goal of diet formulation is meeting nutrient requirements, the impact different feedstuffs have on nutrient utilization (e.g., nitrogen retention) and intestinal physiology (e.g., gut health) of the pig also need to be considered. For instance,...

The objective of this experiment was to determine the effects of dietary crude protein (CP) content and crystalline amino acids (CAA) supplementation patterns on the growth performance of weaned pigs under clean (CSC) or unclean sanitary conditions (USC). One hundred forty-four piglets (6.35 ± 0.63 kg BW) were housed under CSC or USC for 3 wk and assigned to 1 of 3 diets: a high CP (HCP; 21%) and two low CP (LCP; 18%) diets supplemented with 10 crystalline indispensable amino...

1. Introduction The Dutch Ministry of Economic Affairs would like to see an increased number of pig production chains addressing improved pig welfare. The sustainable pork chain called “De Hoeve” wants to be at the forefront in taking the next step in the area of animal welfare. This step consists of no longer docking the tails of the piglets. Up to now, not docking in conventional pig husbandry increases the risk of tail biting [1,2]. More enrichment, space (low...

Introduction Voluntary feed intake is often low and variable directly after weaning. As a result, research has focused on how nutritional stressors can be overcome to stimulate feed intake and subsequently increase performance (Pluske et al., 1997). Thus, highly palatable and nutrient dense protein sources are commonly added to nursery diets to encourage feed intake. Traditionally, this has been accomplished with the addition of milk and animal-based by-products. However,...

1. Introduction Weaning is one of the most stressful events in pig production [1]. Early weaned piglets face several nutritional and psychosocial stressors, including the transition to a solid diet and the abrupt separation of sows and piglets [2]. These events coincide with an immature immune and digestive system [3], which has consequences, such as the reduced activity of digestive enzymes, changes in intestinal morphology, and reduced nutrient digestion in the small intestine...

Introduction There is an increasing global regulatory movement to ensure the judicious use of antibiotics at farms producing milk, meat, eggs, fish, and seafood to reduce the prevalence of antibiotic-resistant pathogens that affect human health. The result of these regulatory changes will reduce the length of time antibiotics can be used, may eliminate the use of antibiotics at farms that are also used in human medicine and end the use of these products at sub-therapeutic levels...

U.S. Soy has a large market in animal feed because of its rich nutritional value and its contribution to animal performance. Although alternatives exist, such as corn protein, and a growing supply of synthetic amino acids, research consistently shows that when compared to these alternatives, soy outperforms.

Introduction Feed manufacturing equipment has been shown to be a potential source of porcine epidemic diarrhea virus (PEDV) cross contamination. Wet decontamination has been found to be the most effective method for decontaminating the surface of feed mill equipment. However, this is not practical in most current commercial feed production settings. Methods to mitigate the risk of PEDV transmission in feed and feed ingredients have been investigated, including chemical...

Introduction Growth promotional feed additives continue to be an area of emphasis for evaluation, especially in nursery pig diets. One of the classes of feed additives that has gained significant interest is probiotics. Probiotics can be defined as live microorganisms which, when administered in adequate amounts, confer a health benefit on the host (FAO/ WHO, 2001). 6 Mechanistically, the modes of action of probiotics are likely to include competitive exclusion of...

Yellow grease is the result of recycling used oil from fast food restaurants and then waste animal fat from slaughterhouses for poultry, swine and cattle is added. Theoretically, yellow grease is filtered and stabilized with antioxidant, then stored for export. Some exporters have the nutritional profile. In fact, yellow grease may be contaminated with toxic waste such as water contaminated with bacteria, residual oil used in motor vehicles (as...

1. Introduction Diet induces a change in the microbial ecology and fermentation end products in the gut, which in turn, influences the nutritional, physiological, and immunological functions of pigs (Brestoff and Artis, 2013; Jha et al., 2019). Cereal grains and different agro-industrial coproducts represent major portions of the pig diet which contains a considerable amount of fermentable carbohydrates like resistant starch (RS) and non-starch polysaccharides (NSP) such as AX...

INTRODUCTION Research to determine the nutritional needs of most micronutrients for pigs was done mainly before the decade of 1990 and focused on avoiding nutritional deficiencies (Gaudré and Quiniou, 2009). Nutritional reference tables represent the theoretical basis for pig feed formulations indicating minimum requirement levels of supplementation (NRC, 2012) or values for best cost to benefit in feed formulations (Rostagno et al., 2017). However, considering...

1. Introduction
The increased awareness of potential negative effects of including antibiotic growth promoters in diets fed to pigs has resulted in an increased interest in producing pigs without using antibiotic growth promoters. However, by eliminating antibiotic growth promoters from diets fed to newly weaned pigs, disease problems may be increased and growth performance may be reduced. In contrast, removal of antibiotic growth promoters from diets fed to...
