Both AID and ATTD can be used to describe the digestibility of Ca for growing–finishing pigs.

Positive antibacterial effect of the combination of medium chain fatty acids and probiotics in weanling diets.

Dietary polyunsaturated fatty acids supplementation may be useful to stimulate puberty onset on gilts.

The optimal Trp:Lys ratio for modern sows during lactation ranges between 0.22 and 0.26.

Pea protein isolate has higher AA digestibility than high protein sunflower meal for growing pigs.

L-glutamine supplementation improves intestinal health, nutrient digestibility and performance in weanling pigs.

Oregano essential oil or quercetin supplementation improves the antioxidant status in finishing pigs under transport stress.

Dietary choline deficiency induces alterations in plasma choline metabolites which are evident at the end of lactation. Betaine and select FAs in milk are sensitive to maternal dietary choline deficiency and day of lactation. Alterations in concentrations of these nutrients may affect early-life neonatal development.

A better fit of nutrient requirements in early lactation improves sow milk yield.

Restricted feeding may improve lean percentage in growing pigs without a negative impact in welfare.

Flavour inclusion in piglet diets is safe even at higher inclusion levels than those commonly used for the industry.

Dietary herbs and fermented herb supplementation during the growing-finishing period improves meat quality in pigs.

Dietary essential fatty acid supplementation in sow during lactation affects further reproductive performance.

Betaine supplementation at 0.63% and 1.26% tended to increase sperm concentration in the ejaculates by 6% and 13%, respectively.

Collectively, SB supplementation could reduce the rate of gilts return to estrus, alter the composition of colostrum and enhance the growth rate of piglets.

Leaner carcasses are achieved with three-phase feeding than with single diet or multy-phase feeding.

Precision feeding is an effective approach to make pig production more sustainable without compromising growth performance.

Maternal vitamin D3 supplementation improves serum concentration in both sows and piglets but, does not affect their performance.

Dietary CLA enhanced cytotoxicity of peripheral blood lymphocytes perhaps through changing its fatty acid composition.

Enzymatic feather meal may become an alternative protein source for piglet diets.

Unsaturated to saturated fatty acids ratio affects carcass and meat quality.

Zinc and protein sources do not affect Zn bioavailability in gestating sows when they are included in adequate levels.

Zearalenone could promote the autocrine action or expression of the ghrelin gene in piglet ovary, and further accelerate the development of ovaries (follicles).

PUFA, oleic acid and stearic acid are the most accurate predictors of the DE and ME for the main fat sources used in swine.
