“…The result of our research revealed enhanced growth performance in barramundi fed on diets supplemented with 5 and 10 g BA/kg, which coincided with an improvement in feed utilization (e.g., FCR and PER) as well as digestive enzyme activities (e.g., protease and lipase) in these groups. Similar to our results, previous studies also demonstrated growth‐promoting effects of BA derivatives in different aquatic animals such as Clarias gariepinus (Owen, Waines, Bradley, & Davies, ), Macrobrachium rosenbergii (Nhan et al, ), Litopenaeus vannamei (da Silva, Nascimento Vieira, Mourino, Ferreira, & Seiffert, ; da Silva, Vieira, Mourino, Bolivar, & Seiffert, ), Sparus aurata (Robles et al, ), Carassius auratus (Sun et al, ), Cyprinus carpio (Liu et al, ), Oreochromis niloticus (Ahmed & Sadek, ) and Ctenopharyngodon idellus (Liu et al, ). It is believed that BA enhances the bioavailability of several essential amino acids, minerals (e.g., phosphorus, zinc and calcium) and nucleotide derivatives through increasing their digestibility and also changes in the host intestinal microbiome, which may led to intestinal health improvement (Ng, Koh, Sudesh, & Siti‐Zahrah, ).…”
