Among the essential amino acids (AA), L-arginine (ARG) is one of the functional amino acids in animals. ARG is a nutritionally very important and essential AA for fish, and is considered the fourth limiting AA in aquafeed. Most of fish species excretes ammonia predominantly through the gills, diffusing NH 3 or NH 4 (ammoniotelic animals). Therefore, unlike mammals, fish have a low he ...

Histidine (Hist) is one of the 10 essential amino acids for fish, and its importance in nutrition expanding the role of this amino acid beyond its function in protein synthesis. It is well recognized that histidine deficiency can impair growth as well as feed conversion in fish (1, 2). Its metabolites, such as carnosine, anserine and NAH (N-acetyl histidine) play an important role ...

Like other animal production systems, aquaculture has developed into a highly globalized trade-dependent industry, therefore as global fish farming continues to increase, the need for formulating nutritionally balanced and cost-effective diets with high-quality protein source is important (Furuya et al., 2010). In fact, nutritional value of protein in the diet for fish is influe ...

Dietary arginine supplementation higher than the recommended levels was shown to improve broiler performance (Murakami et al. 2012; Xu et al., 2018; Zampiga et al., 2018). It suggests that arginine levels needed for maximum performance could be higher in modern broilers, which is probably related to the several functions of arginine on animal metabolism. Besides, arginine enhances th ...
