Not all DF sources are equally suited to influence the provision of energy for the animals.

Since concentrated feeds were first used it has been possible to see that mixing them with water has certain advantages. Probably the most important are a higher consumption and an improved exploitation.

Regardless of the causes we often waste food and the animals do not consume everything that arrives to the farm.

Arginine and glutamine (members of the arginine family of amino acids) are major building blocks for proteins and essential precursors for synthesis of many substances with enormous biological importance.

In order to apply the most suitable feeding regime to newly weaned pigs it is important to balance the trade off between the detrimental effect on performance of feeding levels of protein that are too low to allow maximal growth and those which increase the risk of post weaning diarrhoea.

Tryptophan has positive effects on voluntary feed intake. This greater feed intake leads to increased growth performance and improved feed conversion ratio in piglets, and to lower body weight losses in sows during lactation.

Without a doubt weaning is the most stressful process suffered by a pig, or at least it is up until that moment in its life.

Our research model has been a short chain fructooligosaccharide (scFOS) fed to swine. This compound was selected because it was identified in human and swine milk, was shown to have health benefits in human infants and patients recovering from intestinal anastomosis. The health benefit was believed to occur via the trophic effect of scFOS on the Bifidobacteria population.

Fiber includes a great variety of components with different physicochemical properties that will affect the digestive processes, separately or by combining, in properties such as solubility, viscosity, formation of gels, water retention capacity, bulkiness, endogenous secretions, nutrient absorption, fermentations, intestinal transit, etc.

Fish meal has always been the main source and the preferred choice of nutritionists for quality protein, above all in the formulation of feed for the youngest ages.

With this article we begin the publication of a series of three unpublished articles by José Barceló for pig333.com on the age at weaning. José gave us the articles a few days before his death. As a way of paying homage to him we have decided to publish them posthumously without any alterations.

Piglets face a very stressful process at weaning and feed intake becomes one of the most limiting issues.

An understanding of the molecular structure of the whole protein is vital to understanding its digestive behavior and nutritive value in animals. However, studies on protein internal structures at molecular and cellular levels in relation to nutritive value and digestive behaviors of protein in animals are extremely rarely.

Hulls and kernels of Australian sweet lupins are durable and hard to break, which means without reasonable mechanical grinding nutrients in lupins would not be digested and absorbed efficiently.

Dietary fibre (DF) is an important component of all but a few feedstuffs used in the feeding of pigs. It is resistant to digestion by endogenous enzymes in the small intestine thereby becoming the main substrate for bacterial fermentation, particularly in the large intestine.

A large body of research data exists on the response of pigs to whey. Good quality whey protein contains all the protective components of milk protein.
