L-carnitine supplementation improves sow productive and reproductive performance

The use of vitamin C and ß-carotene in weanling diets does not improve piglet performance or antioxidant activity

Hydrolyzed proteins of intestinal mucosa, yeast and isolated soybean protein may be taken into account as alternative protein sources for piglet diets

The reduction of dietary CP content at weaning with AA supplementation improves nitrogen utilization without affecting piglet performance and intestinal morphology

Low levels of L-arginine supplementation in piglet diets are more effective than high levels on intestinal microvascular development

CLA deposition is not limited by the total dietary lysine level in CLA-fed heavy pigs

Sows fed a diet supplemented with 0.30% of psyllium showed higher body weight along the reproductive cycle but weaned lighter piglets

A minimum level of 1.30% of true ileal digestibility Lys is required to improve ADG and F:G in pigs between 11 to 27 kg of body weight

Piglets eating creep feed during lactation have better small intestine functionality at weaning.

A rice based diet may be more favourable for the transition of weaned piglets compared to a maize based diet.

Low phosphorus levels in gestation diets may not necessarily determine a decrease in the sow performance.

Lactose content in the diet of weaning pigs may vary depending on the conditions to which the animals are raised.

Modifying gut fermentation feeding weaned piglets with fermentable carbohydrates do not necessarily improve performance.

Low Lysine levels with high Leucine levels can represent a strategy to increase the intramuscular fat content.

Providing a well-balanced diet in Threonine is critical in order to maintain the mucosal structure of ileum in early weaned piglets.

Weaning age and dietary crude protein content determine differences on the resistance of weaned piglets to the onset of postweaning colibacillosis.

A low feeding level during the growing phase may be a useful tool to enhance the fatty acid composition in heavy Iberian pigs.

Provision of silage racks to gestating sows is helpful to reduce stereotypic behaviours when sows are housed in large dynamic groups.

Reducing particle size of the lactation diets below 1000 µm do not necessarily represent and advantage for the productivity of the sow during lactation.

Organic acid addition in growing-finishing diets does not modify skatole concentration in the adipose tissue of entire male pigs.

Metabolizable Energy content of crude glycerol varies among weaning piglets and finishing pigs.

Glutamine in the weaning diets can favour a better immune status in piglets.

Feeding lactulose to piglets increases hindgut fermentation, and in the growing pig may determine a better hindgut environment for the development of Salmonella derby

Increases in the tryptophan content in corn-based lactation diets, determines increases in the feed intake and performance of the sow
