Abstract

Guanidinoacetic acid (GAA) is the only direct precursor in creating creatine in vertebrate animals. In addition, creatine plays an active role in energy metabolism by supporting the restoration of high-energy cellular ATP concentrations, such as phosphocreatine. This study evaluated the effect of GAA on the growth performance and internal organs of broilers fed a low-protein diet. A total of 1,176 day-old unsexed broiler chicks (Lohman Indian River strain) were randomly assigned to a 2x3 factorial design with seven replication pens of 28 birds each. The dietary treatment consisted of two levels of protein, i.e., high and low protein, in each growth phase and three levels of GAA, i.e., 0, 600, and 1,200 g/ton. The variables observed in the performance parameters include feed intake, feed conversion ratio, body weight, performance index, and mortality. The internal organ parameters include heart, liver, pancreas, gizzard, gallbladder, caecum, jejunum, ileum, and duodenum. The result showed that GAA did not improve broiler chickens’ performance in all maintenance phases. However, we found that the high-protein treatment (21%) is optimal during the pre-starter phase, while the low-protein (19%) is optimal during the finisher phase. Moreover, 0.06% of GAA showed the highest percentage of the cecum. Overall, GAA did not have a negative effect on internal organs.
