Piglet survival at farrowing and at weaning may be improved by sow dietary energy supply during gestation and lactation

Nutrient excretion may be reduced without affecting growth performance, bone variables, and carcass characteristics in growing-fattening pigs

The use of glycerine in pig diets does not negatively affect pig performance or frequency of histological lesions in tissues associated with methanol metabolism

The use of raw potato starch in weanling diets may reduce the negative effects of postweaning diarrhoea

The MUFA dietary supplementation during the first half of gestation may reduce the incidence of low birth weight

High feed intake and low plasmatic Tryptophan levels during the lactation may be directly associated to sow reactivity

Higher feed intake during lactation let to improve sow and litter performance

Weanling diet composition and vaccinating time may affect piglet growth performance at weaning

The dietary inclusion of wheat straw during the gestation phase improves sow and litter productivity.

Dietary vitamin A supplementation does not affect major fatty acid composition of intramuscular lipids, but leads to a higher C16:0 and total SFA concentration in liver lipids.

Dietary heating may enhance piglet performance by increasing feed consumption just after weaning

The use of sodium butyrate just after weaning may help to stimulate gastric mucosal maturation

Tryptophan supplementation of piglet diets may help to reduce the negative impact of E. coli at weaning

Pea protein concentrate and fullfat soya bean have a negative impact on piglet performance and ileal digestibility compared to regular SBM

Dietary supplementation with soybean hulls and metal amino acid chelated minerals may reduce noxious gas emissions during growing fattening period

Nutrient digestibility may be enhanced by ß-glucanase-protease enzyme blend product supplementation of growing diets

The expression of the responsible genes for trapping, release and storage of fatty acids and glucose may be modulated by altering n-6:n-3 ratio of the diet in pregnant sows

AI boar longevity may be improved by using an adequate feeding programme without affecting semen production and quality

The inclusion of crude glycerol in nursery diets may reduce feeding costs by enhancing feed mill efficiency

In dry feeders/hoppers feed should slightly cover more than half of the feed pan to avoid limiting pig performance

The dietary supplementation with L-Carnitine during late gestation and lactation in sows may increase L-Carnitine level in sow milk, and improve piglets' performance

Dietary ractopamine supplementation in pig diet during the fattening period may improve carcass and primal cuts without affecting pork qualty

The supplementation of slowly released tributyrin and lactitol in piglet diets may overcome the adverse effects of vegetable protein sources during the nursery phase

Independently of the nature of the Fe source in sow diet, the Fe injection at birth it is critical to achieve optimum growth of piglets
