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 Longevity of a breeding female is influenced by a wide variety of factors, one of which is the nutritional management of the female throughout her productive life. In modern pork production, the female becomes a part of the breeding herd at birth. Hopefully, several reproductive cycles follow before her removal from the breeding herd. A sound feeding program focuses nutrition throughout the whole life span of...

Introduction It is now accepted that weaning simultaneously subjects piglets to nutritional (e.g. loss of sow´s milk), psychological (e.g. mixing and moving) and environmental (e.g. change in ambient temperature) stressors and that these and other stressors contribute to growth depression typically observed immediately after weaning. Reducing this post-weaning growth lag is critical as it not only affects...

The high-yielding sow faces many challenges in order to secure that as many piglets as possible are weaned at a satisfactory weaning weight. ● A large number of foetuses may result in prolonged farrowing ● Many and large piglets may result in skinny sows Prolonged farrowings Increasing litter sizes prolong the time of farrowing. A good and problem-free farrowing is among other things secured by...

ABSTRACT Pork producers market their pigs to pork processors that provide premiums and discounts based on predicted carcass lean yield. Recently, some marketing grids have been developed that provide maximum payment for pigs of a specific predicted lean yield percentage. The gilts of some of the leanest, most feed efficient genetic populations are too lean and may be discounted 5 to 6 percent relative to...

Weight and backfat losses, during lactation, are reduced when lactating sows receive a feed containing Rovabio Excel, a NSP enzyme developed by Adisseo.
Six trials throughout the world, concerning more than 500 sows, with different genetics, different feed compositions, various ages at weaning, prove that on average weight loss can be reduced during lactation by more than 3 kg, and backfat thickness by 24 % from...

The genetic improvement has decreased drastically the synthesis and milk production in lactating sows; the technicians have had to resort to the use of replacement milk to piglets during lactation. This problem can be solved applying three improvements:
1-Concentrating nutrients in the diet of lactating
2- Stimulating feed intake during lactation (for example using the meal six times per day, use of flavourings, act.)
3-Using a micronized powder fat to the liver bypass based in...

Mavromichalis et al, 2001, showed that piglets use sucrose as efficiently as lactose, this had been shown by other studies (Jin et al, 1998 and Lee et al 2000). Molasses is a byproduct of the extraction of sucrose from cane or beets, with about 75% dry matter and 50% of sugars. In molasses, sucrose is in equilibrium with glucose and fructose. Molasses is rich in potassium, so one must pay attention to the dietary electrolyte balance to prevent diarrhea. ...

In pigs, energy derived from the diet is digested in the small intestine through enzymatic hydrolysis or fermented in the large intestine by micro-organisms. In growing animals, hindgut fermentation accounts for 8 to 18% of total dietary energy, increasing with non starch polysaccharides (NSP) levels. Sow diets are higher in fibre than pig diets, but little is known about hindgut fermentation in sows.
A trial was designed to...

In his presentation, first of all Jean Le Dividich referred to the piglet´s characteristics after birth: - It is born with a very low energy reserve: very thin (1 to 2% of adipose tissue, without "brown" fat) - No immune protection (agammaglobulinemia) due to the lack of antibody permeability of the sow's epitheliochorial placenta. These low energy reserves...

INTRODUCTION Animals live surrounded by microorganisms (e.g., bacteria, viruses, parasites, etc.) and other antigens (e.g., allergens) that can activate the immune system, which is constantly challenged and must contend with subclinical infections on a daily basis. However, animals show clinical signs of disease quite infrequently because they are equipped with a highly-specialized immune system that affords protection against...

INTRODUCTION Sows are under nutritionally catabolic status during late gestation and lactation especially due to limited protein intake and increased needs for protein to support the growth of fetal tissues (McPherson et al., 2004), mammary parenchymal tissues (Kim et al., 1999; Ji et al., 2006), and milk synthesis (Revell et al., 1998; Jones and Stahly, 1999). The maternal catabolic conditions impair the growth of the fetus and the neonate...

Gaining popularity in Western Europe, but apparantly already used for many years in the U.S. is the use of automated systems for milk supplementation to suckling piglets in the farrowing room. I would like to know from people who are using this kind of system what their experiences are. How much milk do the piglets consume, at what cost, etcetera. Are you not using this kind of system? Then i would like to know what you think about milk supplementation. Thank you in...

Prior to weaning piglets are suckled by the sow approximately every hour throughout the day and night. The frequent suckling of small amounts of highly digestible milk ensures that the small gut is not overloaded with indigestible material. At weaning, pigs must move from frequent and regular liquid food to solid food. They must also adapt to changes in the pattern of food intake. The ability of the pig to adapt to these changes is directly dependent on its...

Due to the severe economic crisis our industry has been enduring over the last two years, it is plausible to assume that a close collaboration between the many segments of our industry will only be accelerated. That evolution will, in turn, enhance the industry's ability to better develop and implement strategies to sustainably produce the most desirable carcass (raw materials) at the least cost. This issue of Cutting Edge addresses the biological, dietary and...
