In the double nursing strategy every week one or more sows nurse two litters simultaneously from birth to weaning.

Protease supplementation in sorghum-based diets may improve protein digestibility, performance and feed efficiency without affecting intestinal health in growing pigs.

Feed and/or dietary amino acid restriction affects feeding behaviour and voluntary feed intake in growing pigs.

Co-mingling of unfamiliar piglets before weaning did not improve performance. Co-mingling and intermittent suckling increased positive behaviour after weaning. Intermittent suckling likely advanced gastrointestinal changes in the peri-weaning period.

Glutamine, glutamic acid and nucleotide affect carbon turnover on stomach of weaned piglets.

Gestation and lactation dietary supplementation mannan oligosaccharide may improve sow and litter performance and immune response.

The objective of this study was to evaluate the survival of PEDV in 9 different feed ingredients when exposed to 60, 70, 80, and 90 °C, as well as the survival on four different surfaces.

Use of coated proteases in sorghum soybean based diets for growing pigs may improve nitrogen retention and reduce nitrogen content in manure.

The interaction between dietary Arginine content and ZnO supplementation may play a negative impact on the antioxidant capacity and inflammatory response in weanling pigs.

Increase crude protein level in lactating diet may enhance milk quality and improve sow and litter performance in high productive sows.

The use of digestible rather than total amino acid in diet formulation clearly improve N retention and reduces N excretion.

Dietary electrolyte balance ranging between 166 and 250 mEq/kg may promote a proper growth rate and nutrient digestibility in weanling pigs.

The SID Lys:ME ratio during lactation depends on a milk yield and the body weight of the sow.

Formulating with high amylose content cereals may improve pig performance and carcass and meat quality at slaughter.

The treatment of DDGS with fiber degrading enzymes my improve dietary nutrient availability and improve performance in growing pigs.

Multi-enzyme supplementation may become a successful strategy to replace antibiotics in weanling diets.

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.
