Dietary supplementation with gallic acid might reduce the incidence of post-weaning diarrhea.

Early development of gilt progeny may be delayed compared with sow progeny and a number of anatomical differences present at birth are also present at weaning.

Weaning is a critical phase in a pig’s life. Group housing of non-littermates before weaning may favour socialisation and hence reduce weaning stress.

Dietary supplementation of coated and uncoated sodium butyrate for lactating sows modified the milk fatty acid profile, but did not affect sow performance nor the performance of their progenies during lactation.

The more straw provided (between 10 and 500 g) the higher the daily weight gain. The feed conversion ratio was not affected by the amount of straw provided.

Increased suckling intensity increased litter weight gain but reduced piglet ADG. Following lactations were not negatively affected by increased suckling intensity of the first lactation. Loss of sow body reserves was reduced for the second lactation.

Gradually weaned pigs performed better around transitions than abruptly weaned pigs and gradual weaning resulted in beneficial long-term effects on behavior.

Results show the importance of lactation length on piglets’ BW variability. Weaning at 25.5 d, equivalent to 7 kg BW, optimizes slaughtering pig performance.

Multi-enzyme supplementation may become a successful strategy to replace antibiotics in weanling diets.

Barley may be a suitable cereal to replace wheat in starter dies for piglets.

Xylanases supplementation of pig diets based coproducts from wheat and corn may improve performance during the growing period.

More than 85% of primiparous sows can be successfully post-cervical inseminated with doses containing 1.5 × 109 sperm cells in the absence of the boar during insemination without impairing the reproductive performance.

Dietary Lys restriction during finisher period in pigs impaired growth performances and was not successful to increase the carcass fat deposition, although it could have positive effects on the intramuscular fat proportion of pork.

The meta-analysis confirmed the significant effect of several well-known factors on the performance and efficiency of grower and finisher pigs, the effects of some less established ones and, importantly, the interactions between such factors.

The use of different dietary energy levels during gilt rearing affects the level of body reserves but not productive and reproductive performance.

Under the conditions of this study, plasma transfer alone does not improve survival of low-birth-weight piglets.
