Study Notes
Guanidinoacetic Acid (GAA) and Creatine
- GAA is an amino acid derivative and precursor to creatine, which plays a significant role in energy metabolism.
- GAA has been explored as an effective alternative to creatine supplements due to creatine's instability during manufacturing and cost.
Effects of GAA on Brain Function
- Increased dietary GAA can increase brain functions and concentration in broilers subjected to heat stress.
- GAA supplementation can increase plasma arginine, making it more readily available for metabolic processes other than de novo GAA production.
GAA Supplementation in Poultry
- Dietary GAA can be used to substitute 150% of arginine in broiler diets with a moderately low crude protein to achieve comparable growth, meat quality, and creatine production.
- GAA supplementation can spare dietary arginine, and supplementing with 1.2 g/kg GAA is the most effective way to boost growth performance.
- GAA supplementation does not affect feed intake in broilers, except at very high doses (6 g/kg) which lead to reduced feed intake.
- Adding coenzyme Q10, taurine, or a combination of the two in broiler diets can improve growth performance.
GAA Supplementation in Swine
- Feeding GAA during gestation and lactation improves multiparity and gilt performance, milk quality, and production, as well as litter growth performance.
- GAA supplementation can be used as an arginine-sparing agent in animals, improving growth, feed efficiency, and growth performance.
Other Effects of GAA
- GAA supplementation can act as an arginine-sparing agent while decreasing mortality related to ascites.
- GAA can improve skeletal muscle development and expression of myogenic genes.
- GAA can be used to replace arginine in animal diets.
