Effect of feeding time and frequency during gestation does not affect farrowing performance.

Lysine deficient diets at the end of the fattening period may promote intramuscular fat deposition affecting fatty acid composition.

The effect of dietary fats differing in fatty acid (FA) composition on the metabolism of saturated FA (SFA) and monounsaturated FA (MUFA) in growing pigs was investigated.

The α-ketoglutarate supplementation may affect intestinal microbiota promoting SCFA production in the intestine.

Porcine Epidemic Diarrhea Virus (PEDV), Porcine Delta Corona Virus (PDCoV), and Transmissible Gastroenteritis Virus (TGEV) are major threats to swine health and contaminated feed plays a role in virus transmission.

The development of piglet immune system under vaccination against PRRSV it is not improved by the use of probiotics and prebiotics or colostrum.

High feeding level during the wean-to-oestrus may increase farrowing rate but also may increase stillborn rate and reduce piglet birth weight.

Sodium butyrate supplementation in finishing diets may reduce Salmonella carriage, shedding and seroprevalence in commercial conditions.

Dietary sugar cane extract supplementation may promote enhanced oxidative stability and improve meat quality in growing finishing pigs.

Fermented soybean meal may become a suitable and economic protein source for weanling diets according nutrient digestibility and intestinal health.

Arginine and other amino supplementation in gestating gilts improve farrowing and litter performance in low prolificity sows (≤14 total piglets born).

Fine grinding improves feed efficiency for meal but not for pelleted diets although pelleting improves average daily gain in growing pigs.

Fiber coming from wheat bran has higher negative impact on protein and fat digestibility than soybean hulls in growing pigs.

The use of purified pig immunoglobulins may clearly reduce diarrhea at similar extend than ZnO in weanling pigs.

Organic Se supplementation in sow diets may improve antioxidant capacity and reproductive performance.

Alfalfa silage may be used as suitable AA and protein source for growing pigs for organic pig production, although its methionine content could also be interesting as alternative feed ingredient for conventional pigs.

Vitamin D deficiency in growing pigs can be cheaply overcome by moderate sunlight exposure.

Encapsulated organic acid supplementation may improve performance due to an improvement of intestinal health and immunity after weaning.

Sow metabolism during lactation is affected by arginine supplementation promoting litter weigh improvement.

A reduction of the environmental impact derived from pig production is possible by a suitable nutrient requirement adjust.

Although the better sow and litter performance for group housed sows with electronic feeding system some improvements are still required in terms of body scratch and locomotion disorders.

Dietary supplementation with microalgae as an alternative to antibiotic use was studied.

Pelleting diets and sodium metabisulfite supplementation previously to heat conditioning may reduce the negative impact of vomitoxin in nursery pigs.

Dietary combination of probiotics, prebiotics and organic acids improve growth, health and immunity in fattening pigs.
