Effects of increasing lysine during gestation on gilts and sows performance
Increasing SID lysine during gestation may promote lean tissue gain on gilts and sows without affecting general performance.

An update on sow amino acid research
Sow nutrition research has historically been only about 2% of the swine scientific literature, but new commercial facilities are changing this.
Amino acid restriction and flaxseed oil supplementation on the performance, carcass traits and meat quality of pigs
Amino acid restrictions for the growing period does not affect growth performance but improves overall efficiency of AA and energy while affects meat quality.
Effects of amino acid and energy intake during late gestation on piglet birth weight and reproductive performance
Increasing feed intake in late gestation improves very little body weight gain of gilts and sows and increases stillborn rate.
Increase of dietary lysine levels in lactation diets on sow and litter performance
Increasing SID lysine levels in lactation diets may reduce tissue mobilisation of the sow while litter weight gain during lactation is improved.
Restriction of feed and/or amino on pigs feeding behavior of group-housed growing pigs
Feed and/or dietary amino acid restriction affects feeding behaviour and voluntary feed intake in growing pigs.
Use of digestible rather than total amino acid affects nitrogen balance in pigs
The use of digestible rather than total amino acid in diet formulation clearly improve N retention and reduces N excretion.
Evaluating low-protein diets for heavy pigs on quality characteristics of dry-cured ham
Environmental impact of heavy pig may be reduced by lowering CP content diets with balanced AA profile without affection ham quality.
Energy and lysine requirements of sows during transition and lactation
The SID Lys:ME ratio during lactation depends on a milk yield and the body weight of the sow.
Composition of longissimus muscle in late-stage finishing pigs is lysine dependent
Lysine deficient diets at the end of the fattening period may promote intramuscular fat deposition affecting fatty acid composition.
Arginine and amino acids supplementation in gestating gilts
Arginine and other amino supplementation in gestating gilts improve farrowing and litter performance in low prolificity sows (≤14 total piglets born).
Arginine supplementation during lactation affects sow metabolism and improve litter performance
Sow metabolism during lactation is affected by arginine supplementation promoting litter weigh improvement.
Use of digestible rather than total amino acid in diet formulation increases nitrogen retention and reduces nitrogen excretion from pigs
One of the goals of swine diet formulation is minimizing nitrogen (N) excretion as well as maximizing N retention.
Effect of heat stress on amino acid digestibility in pigs
Pigs exposed to heat stress increase their body temperature and reduce the size of their intestinal villi, thus increasing the loss of endogenous AAs and reducing the abundance of AA transporters in the intestine, as well as apparent and standardized ileal digestibility of AAs.
Dietary tryptophan: lysine ratio affects reproductive performance of lactating sows
The optimal Trp:Lys ratio for modern sows during lactation ranges between 0.22 and 0.26.
Amino acid digestibility of novel protein sources for growing pigs
Pea protein isolate has higher AA digestibility than high protein sunflower meal for growing pigs.
