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.

Zinc oxide may help to reduce intestinal inflammation in weanling piglets.

Hydrolyzed feather meal is a good AA source for growing pigs but, has to supplemented with Lys and Trp to alleviate their deficiency.

Supplementation of citric acid improves the absorption of dietary Ca, P and protein.

Pig performance an carcass quality are not affected by the source of starch used in growing diets.

Ad libitum feeding during the peripartal period limits excessive loss of body reserves improving litter growth and weaning weight.
