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.

Supplementing diets with 250 mg/kg copper stimulates feed intake and results in an enhancement in weanling pigs’ growth.

Light weight pigs were found to eat more and grow faster per kg of body weight than medium or heavy weight pigs.

Offering a purified source of β-glucans resulted in beneficial reductions in odorous volatile fatty acids in the distal gastrointestinal tract and in excreted manure, and may reflect improvements in N digestibility.

Osteochondrosis prevalence can be reduced by applying deep litter floors with extra space allowance and/or restricted feeding in fattening pigs.

Supplementing sow diets with 250 mg/kg of oregano essential oils during gestation and lactation did not affect the growth potential of and immune responses in suckling piglets.

Sows and piglets diets supplemented with probiotics are effective in maintaining animal performance and control of diarrhea during the nursery phase.

Partial enteral feeding increases superior mesenteric artery blood flow in the neonatal pig compared with total parenteral nutrition.

Feeding co-extruded flaxseed to increase omega-3 fatty acid content in trimmed loin muscle did not result in levels sufficient to meet label requirements and had limited effects on palatability.

The concentration of fatty acids in subcutaneous fat and liver tissues of piglets 35 d after weaning is largely dependent on the CLA content of piglet diet rather than CLA enrichment of sow diet.

Using ileal digestibility values determined in growing pigs to formulate sow diets may lead to overfeeding of sows with protein and can negatively affect overall production efficiency through increased cost and excess nitrogen excretion.

Modifying feed intake during growth may change pork nutritional value and tenderness.
