TL;DR: Glycine plays an important role in metabolic regulation, anti-oxidative reactions, and neurological function and has been used to prevent tissue injury, promote protein synthesis and wound healing, and improve immunity.

TL;DR: Amino acids (AA) have enormous physiological importance, serving as building blocks for proteins and substrates for synthesis of low-molecular-weight substances as discussed by the authors, and therefore, functions of AA beyond protein synthesis must be considered in dietary formulations to improve efficiency of nutrient use, growth, development, reproduction, lactation and well-being in animals.

TL;DR: Arginine plays an important role in conceptus (embryo and extra-embryonic membranes) development in pigs and sheep as mentioned in this paper, and it has been shown that dietary supplementation with 0.83 % L-arginine to gilts consuming 2 kg of a typical gestation diet between either days 14 and 28 or between days 30 and 114 of pregnancy increases the number of live-born piglets and litter birth weight.

TL;DR: Much work is needed with animal models to understand the basic mechanisms responsible for the roles of specific nutrients in fetal and neonatal programming, and to design effective therapeutic strategies for preventing and treating metabolic abnormalities in offspring born to mothers with a previous experience of malnutrition.

TL;DR: Protein hydrolysates hold promise in optimizing the nutrition of domestic and companion animals, as well as their health (particularly gut health) and well-being.
