The AMPs (also called host defence peptides) are small gene encoded peptides of 1 to 5 kDa that have a broad range of activity against gram-positive and gram-negative bacteria, fungi and mycobacteria

A challenge in animal production today is to raise livestock within new environmental rules and regulations. Although most states in the United States regulate swine waste application based on N concentration, more are changing to P-based regulations.

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.

Due to their multiple effects at a physiologic and cellular level organic acids function as antimicrobials, modifiers of the intestinal flora, pH reducers, stimulants of pancreatic secretion and of the growth of intestinal microvilli, improvers of the gastric and intestinal flora, inhibitors of ammoniac production and of other metabolic depressors of growth, as well as energetic.

The consequences of the inflammatory and immune responses on tryptophan metabolism could impair the availability of tryptophan for body protein accretion, growth and all other metabolic processes involving this amino acid.

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.

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

The use of pulped food incites consumption and allows a smoother transition from milk to feed.

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.

The sow’s intake is affected by the interaction of different factors, not just nutritional but also those connected with the animal, handling or system of production.

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.

The swine production industry has a growing interest in the use of essential oils. Essential oils are products of complex origin. They have antimicrobial and antioxidant effects, they stimulate appetite and intestinal secretions and they are even immunostimulants.
