Increasing dietary lysine and energy levels improves growth performance and apparent total tract digestibility of nutrients.

A mathematical model serves as a tool to study phosphorus digestibility for different feedstuffs and feeding strategies.

CLA administration to sows reduces backfat thickness loss during the lactation period and lets to higher piglet weight at weaning.

Glutamine supplementation may be useful in reducing the severity of weaning-related gastrointestinal infections.

Supplementation with folic acid in the diets of lactating sows increases milk production, improves milk quality and the performance of piglets.

The preference for the different feed ingredients should be taken into account during diet formulation as well as nutrient composition and ingredients cost.

Higher lysine levels than those recommended by the NRC improve reproductive performance for multiparous gestating sows.

High levels of acetic acid in fermented liquid feed can impair palatability of piglets.

Feeding omega 3 fatty acids as a way to increase the sows’ litter size.

Increasing feeding frequency from 2 to 6 times daily increases ADG and feed efficiency of floor-fed, group housed finishing pigs.

Chicory inulin and raw potato starch as ingredients to reduce the boar taint of meat from intact male pigs.

No differences in further processed product characteristics among physically and immunologically castrated male pigs were found.

The role of zinc oxide in improving piglet health is via a different mechanism to that previously proposed.

A combination of dietary crude protein and P reduction with added phytase is the key to optimize pig production efficiency, while minimizing their environmental impacts.

The greatest values for apparent total tract digestibility of P are obtained when the dietary Ca to P ratio is around 1.1:1.

The conjugated linoleic acid (CLA) concentration in pig tissues increases linearly by the CLA supplementation in diet.

Temporal administration of probiotics to pregnant sows has clear effects on the establishment of gut microbiota to piglets after weaning.

Under ad libitum feeding, a low crude protein amino acid supplemented diet can reduce N excretion in manure with no impact on animal growth.

Glycerol can be added in nursery diets up to 10%, while improving pig performance.

Finisher pigs accumulate area bone mineral density at much higher rates than weaner pigs.

Fermentation of cereals alters the dietary composition and influences the flow, composition, and ileal digestibility.

Fermentable carbohydrates as a way to reduce protein fermentation and to promote beneficial microbial populations in piglets fed rice based diets.

Corn can be substituted by sorghum to prevent exceeding softness of fat depots when the energy level of the diet is increased by adding choice white grease.

Consumption of diets containing seaweed-derived extracts does not diminish faecal shedding of Salmonella in post-weaned piglets.
