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.

In the refeeding period, growth was associated with internal organ growth, whereas skeletal muscle was not affected, suggesting that compensatory growth does not have practical benefits for pig production.

Yeast fermentation products showed better performance, especially in the presence of the active enteric disease.

The incorporation of wheat bran or ZnO in the diet improved gut health, but the simultaneous incorporation of both compounds increased E. coli counts, indicating a negative interaction.

Transport of n-3 PUFA from sow to piglet is higher via milk than via bloodstream in the uterus.

Any mode of tuna oil supplementation was efficient in enriching n-3 fatty acid, but care should be taken in producing dry sausages due to their susceptibility to rancidity during storage time.

Lactulose recovery in the urine of pigs after weaning is not associated with risk factors for infections, but it seems to be useful to measure the paracellular barrier function.

Offering pigs a low-P diet from 10 to 100 kg BW lead to reductions in P excretion, however, growth performance and bone mineralization were compromised.

Feeding high-fat diets and 36 h fasting could be effective production practices to reduce pre-slaughter muscle glycolytic potential and, consequently, improve pork quality.

When cost per mole of methionine activity is not different, methionine hydroxy analog may be the better choice in low-fiber diets and DL-methionine in high-fiber diets.

Administration of flavor could increase creep feed intake pre-weaning and piglet average daily gain post-weaning.

Although uniform grouping appears to aid the reduction in slaughter weight variation and improve FCR, its effect is dependent on dietary regime.

Feeding conjugated linoleic acid up to 1.0% to growing-finishing pigs does not significantly alter either immune system (innate or cell-mediated) or blood chemistry variables.

The fermented garlic powder supplementation added at the level of 2 g/kg can improve growth performance, while improving meat marbling and firmness score.
