Influence of low molecular weight chitooligosaccharides on growth performance and non-specific immune response in Nile tilapia Oreochromis niloticus

A 50-day feeding trial was conducted to evaluate the effects of five different levels of low molecular weight chitooligosaccharides (LMW-COS) (0, 0.1, 0.2, 0.4, and 0.8 g kg −1 ) on growth performance, serum parameters, body composition, and non-specific immunity in Nile tilapia ( Oreochromis niloti...

Zusammenfassung:	A 50-day feeding trial was conducted to evaluate the effects of five different levels of low molecular weight chitooligosaccharides (LMW-COS) (0, 0.1, 0.2, 0.4, and 0.8 g kg −1 ) on growth performance, serum parameters, body composition, and non-specific immunity in Nile tilapia ( Oreochromis niloticus ). A total of 600 fish were divided into 5 treatments with 4 replicates of 30 fish per tank. The results showed that dietary supplementation with 0.4 or 0.8 g kg −1 COS significantly improved the final body weight, specific growth rate, feed efficiency rate, and protein efficiency ratio of fish ( P
