Abstract

This experiment was aimed to investigate the effects of dietary protein level on growth performance, physical indices and body composition of Taiwan loach. A total of 720 Taiwan loach with an initial body weight of (8.57±0.35) g were divided into 4 groups with 3 replicates per group and 60 fish per replicate. Four experimental diets were formulated with the protein levels of 25%, 30%, 35% and 40%, respectively. Each diet was fed to one group for 60 d. The results showed as follows:the final weight (FW) and weight gain rate (WGR) of Taiwan loach were initially increased and then tended to stabilize with the increase of dietary protein level. Both of FW and WGR reached the highest values when dietary protein level was 35%. The feed conversion ratio (FCR) was initially decreased and then tended to stabilize with the increase of dietary protein level, and the minimum value was obtained when dietary protein level was 40%. When dietary protein level raised from 35% to 40%, FW, WGR and FCR were not significantly changed (P>0.05). The broken line simulation results of WGR and FCR showed that the Taiwan loach had the highest growth rate when dietary protein level was 34.57%, and had lowest FCR when dietary protein level was 35.47%. With the increase of dietary protein level, all of protein efficiency ratio (PER), protein retention efficiency (PRE) and survival rate (SR) increased at first and then decreased. By quadratic polynomial regression analysis, dietary protein level was 33.6% and 34.68%, respectively, when the Taiwan loach had the highest PER and PRE. With the increase of dietary protein level, both of viscerasomatic index (VSI) and hepaticsomatic index (HSI) were initially decreased and then tended to stabilize. Crude protein content of whole body was initially increased and then tended to stabilize with the increase of dietary protein level, while crude lipid content of whole body was initially decreased and then tended to stabilize. The results indicate that appropriately increase of dietary protein level can improve fish growth rate, and increase edible part content of fish, improve the PRE and PER. But it can decrease PER and PRE when dietary protein level is too high. Under the conditions in the present experiment, the suitable dietary protein level is 34.57% to 35.47 based on comprehensive analysis of growth performance and protein utilization.
