The Brix refractometer provides a simple, fast and inexpensive estimation of colostrum IgG in sows.

Orange pulp and carob meal fibre could decrease NH3 y CH4 emissions from slurry.

Duration of water restriction did not affect water consumption on a 24-h basis, nursing behaviour or performance.

No different bioavalilability is observed between dl-Met and l-Met for piglets.

Drinkers suppression it not recommended in growing-finishing pigs fed with liquid diets.

Current results confirmed that teats used in first lactation produce more milk in second lactation, and that piglets are able to detect this difference.

Feed presentation in crumbles or mash for does not affect sow and litter performance.

An abrupt change between diet forms on finishing pigs can affect growth performance.

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

Crossbreed and energy level affects growth performance and carcass quality.

Colostrum production and immunoglobulin concentrations to conjugated linoleic acid during late gestation.

Crude protein restriction during the growing period may have a positive impact on meat characteristics for dry-cured products.

Oral administration of 50 mg/kg BW NCG to newborn piglets improved growth performance, increased the endogenous synthesis of arginine and arginine family of amino acids, jejunal lactase activity and cecal Lactobacillus spp. numbers, and stimulated secretion of ileal sIgA.

Catechins may exert a successful antioxidative capacity in early gestation improving sow reproductive performance.

High inclusion of soybean hulls may be used in finishing diets without without a negative impact on performance.

Energy supplementation to neonatal piglets of low birth weight may reduce piglet mortality.

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

Proper amounts of sugar beet pulp in weanling diets may improve post-weaning performance.

Consumption of nursery starter feeds containing high concentrations of ZnO is associated with post-weaning anemia.

A high dietary amylose/amylopectin ratio improves growth performance, carcass traits, and meat quality in finishing pigs.

The IR method ascertains whether piglets are receiving adequate maternal antibodies until their own immune systems are developed.

A proper feed restriction during rearing period may be a successful strategy to reduce lameness in gilts.

Results show that, expressed as per kg of BW, replacing SBM with RSM in finishing pig diets marginally decreased global warming potential (GWP) and energy use (EU) but decreased land use (LU) up to 12%.

Pigs performed equivalent in both systems, but from an animal welfare view we recommend dry feed to growing pigs.
