Maternal Nutrition and Foetal Development
Low maternal feed levels cause a reduction in muscle fibre numbers, whereas enhanced maternal nutrition resulted in a higher number of muscle fibres in specific muscles.

Antimicrobial peptides as an alternative to antibiotics in pigs nutrition
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
Phosphorus requirements of growing-finishing pigs reared in a commercial environment
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.
Use of Oligosaccharides in Swine Nutrition
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 in piglet feed
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.

ArticleOrganic acids: new opportunities in porcine nutrition
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.

Why tryptophan is an important amino acid for piglet nutrition
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.
Alternatives to fish meal for piglets
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.

ArticleFeed palatability and voluntary feed intake in pigs
Piglets face a very stressful process at weaning and feed intake becomes one of the most limiting issues.
Protein structure: Implications in Animal Nutrition
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.
Lupins in pig diets: competent alternative to soybean meal (2/2)
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 in nutrition and health of piglets
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.
Data sheets: raw materials and additives
Technical sheets of the main raw materials and additives used in swine feed. They include a comparison of nutritional values from various sources, product
Lupins in pig diets: Competent alternative to soybean meal (1/2)
Australian sweet lupins are a predominant protein source in Australian pig diets due to economic rationale as opposed to soybean meal (SBM) which is commonly used in most other countries.
Feeding of lactating sows
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.
Whey Products in piglet diets
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.
Use of plant extracts in swine
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.
Dietary strategies to reduce food-borne pathogens in pigs
In preliminary studies post-weaning diarrhea-causing E. coli and Salmonella populations were reduced by feeding colicins to weaned pigs.

ArticleEnergy requirements of growing pigs: Practical implications
Practical diet formulation takes into account more than the response of the pig to increasing dietary energy. Available feed ingredients, feed processing capability, and economic value of average daily gain also have an impact on determining the most economical dietary energy level.

Magnesium in Pig Nutrition
Dietary Mg supplementation has been observed to improve pork quality, specifically color and fluid loss.
Alimentation of replacement sows
The entrance of gilts to the production system and the strategies followed up to the first lactation is of vital importance for the economic cost-effectiveness of sows since these strategies have a direct effect on the subsequent productivity and longevity
Fermented liquid feed for pigs
Traditionally, liquid feeding systems developed in areas where liquid co-products from the human food industry were abundant and cheap
Dietary fibre as microflora modulator in pigs
Certain species of the resident bacteria are known to provide benefits to the host. These are the lactic acid producing bacteria (LAB), which include the Lactobacilli, Bifidobacteria, members of the Streptococci, and several other species. The amount and composition of substances reaching the large intestine can be readily modified by diet and, in terms of bacterial substrates, it is the fermentable substrate such as oligosaccharides, starches and non starch polysaccharides (NSP) which are most important.
Plasma prevents and reduces E. coli diarrhoea in piglets
One of the main properties of dietary plasma is a substantial stimulation of feed intake after weaning (25%!). Many experiments demonstrated that a high feed intake after weaning prevents intestinal damage (villus atrophy).
