Lowering dietary CP reduces N excretion while maintaining pig performance and carcass composition.

Black pepper supplementation increased the HDL and vitamin C levels in the serum profile in growing pigs.

Tea tree oil supplementation improves the intestinal mucosal immunity when fed to weaning piglets.

Crystalline AA supplementation allows CP reduction of 126g SID CP/kg without affecting litter growth.

Poultry fat combined with flaxseed oil and vitamin E at different levels may be used as fat source for G:F pigs without affecting carcass composition and meat quality.

Ethanol extract of mango seed could be used as successful natural antioxidants in G:F pig diets.

C. utilis can replace up to a 40% of CP while maintaining growth and improving digestive function.

The Danish feeding strategy showed an improved litter size and born alive piglets.

Inclusion of 6% moringa leaf meal positively modifies the fatty acid profile of pork meat.

The optimal SID Trp:Lys differs depending on the pigs’ BW and the parameter measured.

Warm-pressed rapeseed pressed cakes can be used in weanling diets but at low inclusion levels.

Feeding management related to time of feeding in restricted gestating sows may enhance sow performance.

Lecithin alone or combined with L-carnitine produces contrary effects on PUFA fat content.

Oregano and rosemary dietary supplementation modulates immune response and improves polyphenol content in meat.

Brown rice could be a suitable alternative to replace maize in weanling diets for piglets.

Combining vitamin D3 and 25(OH)D3 in sow diets improves the vitamin D status for both the dams and their offspring.

Alternative protein sources, such as micro-algae or larval meals, do not compromise final pork quality traits.

Dietary chromium propionate inclusion may benefit growth performance in heat-stressed finishing pigs.

Faba beans can a suitable proteins source for weanling diets, with a potential inclusion level up to a 20% in diets for young pigs.

Dietary inclusion of Pichia guilliermondii during gestation may improve prolificity while reducing low body weigh category piglets at birth.

Feed practices have changed and concentrations of some elements may now be lower. Phosphorus concentration decreased up to 36%, concurrent with introduction of phytase. Most trace elements also decreased, but Zn doubled in nursery manure over 20 yr.

Independently of the nature of Zn source used, higher levels of added Zn seem to improve pig carcass characteristics.

Dietary cysteamine hydrochloride supplementation in finishing pigs may promote the stability of pork color by reducing oxidation.

Dietary B. licheniformis and B. subtilis supplementation may reduce noxious gas emissions in growing pigs.
