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.

Evonik’s animal feed solutions quench livestock thirst and reduce the environmental impact of meat and dairy production WHITEPAPER According to the UN, four billion people experience severe water scarcity for at least a month a year – and due to our unsustainable use of freshwater and other resources, water stress will increase further. One of the drivers is water-intensive meat and dairy production, which accounts for roughly a quarter of the global water...

Background and objectives: It was hypothesized that not only the extent of protein digestibility at the end of the ileum influences pig performance and risk for post-weaning diarrhea (PWD), but rate of protein digestion also influences performance and gut-health post-wean. Therefore, a 2-step in vitro assay that simulated nursery pig gastric and small intestinal protein digestion over-time was developed in collaboration with Wageningen University and ForFarmers (Chen et al.,...

INTRODUCTION Antibiotics have given significant contributions to the human food production chain during their almost 80 years of use. Such contributions include a reduced incidence of bacterial disease, improved animal health status, and an overall enhancement in production efficiency (1, 2). However, due to concerns of antimicrobial resistance and its consequences to human health, the entire food-producing industry is under pressure to remove antibiotics from animal production...

Introduction: The objective of this study was to evaluate the effect of providing a special feed preparation with a new feed additive based on probiotics to newborn piglets in the first day of life, on their performance during the lactation period. Oral administration of porcine lactic acid lactic bacteria in the first hours of life permits an early colonization of the intestine by beneficial microorganisms that can hinder or prevent a later colonization by pathogens. An...

INTRODUCTION According to new concepts about human health and increase on protein demand there was significant improvement in carcass quality of pigs to supply market which seeks a pork lean meat. Thus, it should be considered some conditions that impose changes in nutritional requirements of pigs, such as genetic potential for meat production, gender and age for maximal performance. Amino acid levels in most of diets are recommended from the data reviewed (National...

Background Porcine epidemic diarrhea virus (PEDV) is an enveloped single-stranded positive sense RNA virus belonging to the Order Nidovirales, the family Coronaviridae and the genus Alphacoronavirus (Saif et al. [1]). Following detection in the US swine population during May, 2013, the virus spread rapidly across the country and 6317 cases of Porcine Epidemic Diarrhea (PED) have been confirmed in 29 states as of May 3, 2014 [2,3]. While little information is known regarding the...

INTRODUCTION Phosphorus is an essential mineral for the formation and maintenance of bone structure, playing additionally a number of functions in the body. According to UNDERWOOD & SUTTLE (1999), phosphorus is found in a high concentration in bone tissue where together with calcium they form hydroxyapatite, which is the major constituent of the skeleton. Phosphorus portion not related to the structural function in the body is contained in high-value organic molecules,...

Introduction Porcine Epidemic Diarrhea Virus (PEDV) is an enveloped single-stranded positive-sense RNA virus that was first identified in the United States in May 2013. Epidemiological and controlled experiments have shown that complete feed or feed components can be one of many possible vectors of transmission of PEDV. 1 Previous research has shown that a 2% and 1% mixture of caproic, caprylic, and capric acids can reduce the risk of PEDV in a complete swine diet....

Introduction Manganese is an essential trace mineral that is a key component in carbohydrate, lipid and protein metabolism. According to the NRC, 2 the quantitative requirement for Mn for nursery and finishing diets ranges from 2 to 4 ppm. Assuming bioavailability is not a concern, many swine diets today meet the NRC 2 estimated requirement for Mn from the major dietary ingredients before a trace mineral premix is added to the diet. However, due to the...

INTRODUCTION The selection of animals for improved production traits has been, for a long time, the major driver of pig breeding (1, 2). More recently, because of the increasing concern with environment, new selection criteria have been explored, such as nitrogen (N) or phosphorus (P) excretion, which are related to both feed efficiency and environmental impact (3). Residual feed intake (RFI) was also proposed as a possible selection criterion to simultaneously improve feed...
