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.
Introduction The aim of efficient pig production is to maximize growth, which can be aided by the inclusion of specific growth promoting substances to the feed. Yakrifit (Ayurvet Limited, India), a polyherbal product containing ingredients Andrographis paniculata, Eclipta alba, Picrorhiza kurroa, Phyllanthus niruri, Tephrosia purpurea, Boerhaavia diffusa are documented for their hepatoprotective, hepatoregenrative, hepatostimulant properties and...

A recent trial conducted in Brazil on pigs aged between 49 and 144 days confirms that including Rovabio ® Max, Adisseo’s multi enzymatic product in a corn-based diet improves the average daily gain, feed conversion and carcass quality of the pigs. Enzyme supplementation is efficient in reducing costs, by lowering nutrient content of the corn-soybean diets without compromising performance. The use of...

Introduction Rice bran is a non-traditional, widely available feed ingredient regarded as a source of energy (Agudelo, 2009). It has been reported that up to 30% inclusion of rice bran in diets of growingfi nishing pigs does not depress growth performance and increases profi t margin (Lekule et al., 2001). The energy content of rice bran is equivalent to about 85% of the net energy in corn (2,040 vs. 2,395 kcal/kg, respectively; NRC, 1998). Rice...

Introduction There is a growing interest in the production of high quality dry-cured meat products for niche market, sometimes associated to the production of autochthonous pig breeds. This requires the production of fat pigs slaughtered at heavy weight (140-160 kg), where fat content and composition play a determinant role in the nutritive, sensory and technological quality of the meat (López Bote, 1998). Fat pigs...

For more than a century nutritionists have been interested in the effect that dietary electrolyte balance has on animal health and performance. It is nowadays well established that the dietary electrolyte balance represents a challenging area that allows nutritionists to adapt diets of production animals according to their physiological stage and also to environmental challenges such as heat stress. Electrolytes have four important physiological...

Background The mammary gland (MG) secretion is essential for the survival of neonatal mammals [1]. This organ is a tertiary extralymphoid tissue with non-organised lymphoid components [1,2]. Its vasculature and epithelium expand in size during gestation and lactation. In all mammalian species, this gland is colonised by T and B lymphocytes [3-6]. T lymphocytes accumulate in the MG during gestation whereas B cells and their plasma cell derivatives...

Introduction With costs of pig production under increasing pressure, the nutrition of young pigs is of increasing interest, as this period is critical to the subsequent performance of the animals through to market. Optimising growth rate and feed efficiency at this time are therefore key requirements for success in today´s animal production systems. While antibiotics are available to assist in improving growth during...

With an increasing awareness of environmental contamination, trace minerals have come to the forefront for further research. Public concerns are mainly related to soil (accumulation and runoff of minerals from land where manure is applied), water (surface and ground water), and air quality issues (Stalder et al., 2004). To date, pigs have been fed concentrate diets, formulated to provide a margin of excess trace minerals and other nutrients in order...

The survival of neonate piglets depends directly on the acquisition of maternal immunity via colostrum, and milk affording systemic and mucosal protection, respectively. Whereas colostral IgG are mainly due to accumulation of blood IgG in the acini of the mammary gland at the end of pregnancy, milk IgA originates from plasma cells; according to their homing receptors these cells orginate form separate mucosal compartments in the respiratory tract and intestine....

Abstract Clostridium difficile is an important cause of enteric disease in humans. In pigs Clostridium difficile can cause neonatal enteritis and can be isolated from faeces from diseased and healthy animals. According to recent research, isolates from humans and animals show genetic and phenotypic overlap. In The Netherlands, strains isolated from diseased piglets were indistinguishable from strains isolated from Dutch patients. These...

It is now well recognized that the gastrointestinal tract of the pig is colonized by an abundant and taxonomically diverse microbial community. Because each of the species of organisms in the intestine possess a different "tool box" of metabolic capabilities, the relative proportion of different species of organisms changes in response to a variety of factors including age, diet composition, rearing environment and possibly genotype. Indeed, chemical composition...

Probiotics, including live yeast and lactic acid bacteria cultures, have been reported to improve performance of weaned piglets. Milk replacer supplemented with Saccharomyces cerevisiae Sc 47 (Actisaf) and fed to weaned piglets showed improved postweaning growth and reduced number of enterotoxigenic E. coli (ETEC) in piglets after weaning, suggesting an immunomodulatory role of Sc 47. The objective of the present study was to evaluate the effect of Sc 47 dietary...

SUMMARY Crude glycerin is a by-product of the biodiesel production, which has been shown to be a good energy source for swine. There is variability in the energy available from crude glycerin, which is partially explained by the glycerin content of the crude glycerin. Up to 15% crude glycerin has been fed to pigs without negative consequences. Methanol, which is potentially toxic to swine, will be present in varying...

ABSTRACT This experiment was conducted to determine three levels of lysine with three levels of methionine on growth performance of finishing pig. Treatment diets were calculated for 3 levels of lysine (0.780, 1.025 and 1.270 %) and 3 levels of methionine (0.240, 0.315 and 0.390 %). Thirty-three crossbred pigs (Large white X Landrace X Duroc, 67.00 kg average body weight) were used. Twenty-seven pigs were used as experimental diet ( 9 treatments, 3...

In a time with very high feedstuff prices it is extremely relevant to focus on the possibilities rendered by a better feed conversion. If the feed efficiency is increased by 0.1 per kg gain it results in app. 2 Euros extra in gross margin for one finishing pig It is obvious that slaughter pig production is an area, in which a better feed economy provides the most apparent effect, the issue is, however, not less important for sows and...

There can be little doubt that dietary habits in western populations have changed dramatically since the middle of the last century. Current trends are driven by convenience and changing domestic practices. Vegetarianism is on the increase, especially in younger females, and red meat consumption has fallen in response to BSE awareness and its possible link with vCJD. For example, vegetarianism in the UK currently stands at 5% of the population, with the figures...
