These results revealed that commercial swine may be deficient in serum vitamin D at varying times of the year, and feed-supplement concentrations may vary.

These results suggest that it is possible to manipulate dietary insulin response in cyclic gilts and, thus, improve reproductive efficiency when feeding starch as the main energy source during the late luteal and follicular phases of the cycle.

Insulin, acylated ghrelin and cortisol could be used as biomarkers to detect situations resulting in a poor energy balance in order to improve handling programs.

Mussel meal can be used as protein sources in pig diets maintaining performance and meat quality.

The use of B. juncea in pig diets reduces feed intake and performance during de growing-finishing period.

The inclusion of brewery yeast hydrolyzate improves immune response in weanling pigs

Tryptophan requirement of pregnant sows increases from 1.7 g/d in early to 2.6 g/d in late pregnancy.

Higher NE content should be recommended for females slaughtered at 120kg of BW.

Sows with high peripartal feeding show highest colostrum yield and better colostrum composition.

The esterified palm acid oils high in MAG and DAG increase saturated fatty acid deposition.

Low concentrations of commercial potentiated ZnO is effective in against of ETEC-challenged weaning pigs.

The information synthesized is expected to open new avenues for a large scale use of insect products as animal feed.

Fatty acid composition of pork lean and fat may be altered by reducing dietary CP and supplementing AA.

Altogether, these results indicate that modifying feeding practices could help to prepare animals to overcome an influenza infection.

Anterior teats appear to contain more IgA and IgG than the posterior ones in sows.

High inclusion of wheat-corn DDGS reduces growth performance and ATTD of energy in growing pigs.

Reducing post-mating feed intakes to maintenance levels impaired embryo survival.

Bacillus licheniformis and Sodium Butyrate may reduce the colonization of Salmonella in piglets.

Fruity flavor inclusion is better accepted by sows and piglets than sodium butyrate.

High inclusion of citrus pulp improves palatability of pork products but decreases pig performance.

Dietary novelty may be a method to stimulate early exploratory behaviour, feed intake and performance.

Camelina cake may be an alternative energy source for swine diets but with low digestibility of AA and CP.

Stevia rebaudiana, Citrus sinensis and extracts of hot-flavored spices did not induce beneficial effects on post-weaned piglets.

Data on this article provide proof of concept that contaminated feed pellets (complete feed) can serve as a vehicle for PEDV infection of naïve pigs using natural feeding behavior.
