Nitric oxide (NO) is a signaling molecule in the cardiovascular system. The precursor of NO in animals is arginine, and its performance has been clearly confirmed. To solve the problem of its costly and can cause amino acid imbalances, NCG (N-carbamylglutamate) is used to increase endogenous arginine production in animals. It helps address issues of intrauterine growth restriction, post-weaning growth lag in piglets, placental nutrient transport, birth weight, intestinal function of newborn animals, growth performance to shorten days to the market. It also promotes capillary development and causes relaxation of vascular smooth muscle. Polyamines can promote protein synthesis, enhance animal immunity, increase milk production, and improve milk quality.

Guanidinoacetic acid is a feed additive containing guanidinoacetic acid (GAA), which is a metabolic precursor of creatine. Methionine forms creatine through methyl, stored in muscles, and serves as an energy source for muscles, brain, or reproductive glands. It can optimize animal energy metabolism, reduce feed costs whilst maintain growth performance and meat quality. In muscles, creatine rapidly replenishes ATP in the form of creatine phosphate, improving energy supply and efficiency. The supplementation of 肌能can both reduce feed energy levels and maintain growth performance. In high-producing pigs, it can significantly improve the number of piglets born and weaning weight of sows, increase piglet survival rate and growth speed, improve feed efficiency and daily weight gain, and lean meat percentage in growing-finishing pigs.
