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.

Importance of a proper balance between carbohydrates and nitrogen to obtain an optimal SCFA profile in large intestine.

Compensatory growth affects metabolism of the animals, although these changes have no impact on meat quality.

Diets of sows did not have major impact on glycogen pools or on mobilization of glycogen by piglets.

Chicory and ribwort can be included in diets as a fiber source, without negative effects on piglets’ performance.

Tryptophan supplementation does not reduce aggression in sows at mixing, but increases litter size at farrowing.

Mixtures of essential oils differ considerably in their effects on growth performance and nutrient digestibility in piglets.

Diet fibre content, but not feeding level, affects the rate of digesta passage in pigs.

Incorporation of fermented wheat germ extract into pig feeds may improve pig performance during the growing phase.

Offspring of sows provided 25-hydroxycholecalciferol obtained a markedly improved vitamin D status.

Barley is an efficient cereal to reduce indole in the adipose tissue in male pigs.

The correlation between feed and water intake is constant until day 60 of pregnancy. Then, at the end of pregnancy, there is a feed adaptation and the relationship decrease.

Dietary C18:2n-6 concentration was a better predictor of carcass fat iodine value than diet iodine value product.

Maternal seaweed extract and fish oil supplementation from day 109 of gestation until weaning stimulates growth performance and starter feed intake in weaning pigs.
