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.

An enhanced feed and water intake during lactation may increase weaning weight of piglets and decreases relative body weight loss of sows.

Metabolite combinations produced by L. plantarum strains are potential alternatives to antibiotics that could be used as growth promoter in postweaning piglets.

Different probiotic complexes of lactic acid bacteria improved growth performance and feed conversion in the first two weeks post-weaning, but the gut environment was improved in all period.

Dietary conjugated linoleic acid increases intramuscular fat content in finishing pigs.

Gestation diets containing protein at 50 and 250% of recommendations led to marked changes in protein and fat metabolism in gilts resulting in fetal growth retardation of 15%.

Restricting energy during the gilt development slightly delays the mean age at puberty.

8% crude glycerol can be added to the diet and used as an effective alternative energy source to partially replace corn.

Barley-based diets have more beneficial effects on gut health, oat-based diets have higher potential to enhance beneficial microbial populations and endogenous β-glucans show better prebiotic properties.

Feeding a single amount of amino acids (AA) throughout gestation results in overfeeding AA in early gestation and underfeeding AA in late gestation.

The expression of Sepw1 gene is associated with the enhanced water-holding capacity of meat.

Diet and ingredient switching does not affect pig performance during the finishing period.

The use of mycotoxins absorbents in sever vomitoxin contaminated diets may reduce the negative impact of vomitoxin on piglet performance.

Feeding low CP, AA supplemented diets can help to improve poor growth performance and enteric disorders of the weaned pigs.

Dietary supplementation of n-3 fatty acids during lactation improved the growth of nursing piglets.

Osmotic resistance of erythrocytes was not altered by increasing amounts of n-3 PUFA, whereas oxidative stability of erythrocytes, as well as oxidative parameters in plasma, were affected.

The automatic feed blending system may help to meet nutrient requirements reducing feeding cost during the fattening period.
