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.
The importance of dietary protein and Amino Acids after weaning
There is a widespread trend throughout Europe to decrease the protein levels in feeds, together with an adequate supplementation of industrial amino acids.
L-glutamine affects piglet performance, immunity and intestinal health after weaning
L-glutamine supplementation improves intestinal health, nutrient digestibility and performance in weanling pigs.
Precision feeding can significantly reduce lysine intake and nitrogen excretion without compromising the performance of growing pigs
Precision feeding is an effective approach to make pig production more sustainable without compromising growth performance.
Progressive reductions in crude protein and indispensable amino acids on carcass quality and uniformity of heavy pigs
In terms of carcass quality, crude protein and essential amino acids could be reduced in finishing diets.
Assessment of bioavailability of dl-methionine compared with l-methionine fed to nursery pigs
No different bioavalilability is observed between dl-Met and l-Met for piglets.
Requirement of standardized ileal digestible valine to lysine ratio for 8- to 14-kg pigs
In conclusion, 0.70 SID Val : Lys is suggested as the Val requirement for 8 to 14 kg individually housed pigs.
Effects of sex and dietary lysine on performances and serum and meat traits in finisher pigs
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.
Low dietary protein decreases ETEC proliferation and attachment in the intestinal mucosa
Low-protein diets with balances amino acid profile decrease ETEC colonization in jejunal mucosa.
Phase feeding of sows in gestation
The nutrient requirements of the sow change during gestation and the feed provision must meet this demand; hence the need for phase feeding.
Tryptophan requirement of pregnant sows
Tryptophan requirement of pregnant sows increases from 1.7 g/d in early to 2.6 g/d in late pregnancy.
Precision feeding can reduce amino acid requirements of growing pigs by more than 25%
Feeding growing-finishing pigs with daily tailored diets using precision feeding techniques is an effective approach to reduce nutrient excretion, without compromising pig performance or carcass composition
Dietary crude protein reduction and AA supplementation affects tissue fatty acid composition in pigs
Fatty acid composition of pork lean and fat may be altered by reducing dietary CP and supplementing AA.
Effect of susceptibility to ETEC and of dietary Trp on gut microbiota diversity observed in healthy young pigs
An Italian study investigated the intestinal bacterial diversity of healthy pigs with different susceptibility to ETEC and fed different Trp levels.
