Protein efficiency ratio and feed efficiency are utilized as quality indicator for fish diet and its amino acid balance.

Net protein utilization (NPU) and protein efficiency ratio (PER) were worked out by using the formula of (Miller and Bender, 1955) as under:
However, feed and protein efficiency ratios of fish in 15 WF treatment were significantly (p<0.
The food intake and gain in body weight of rats, food efficiency ratio (FER) and protein efficiency ratio (PER) of supplements are presented in Table 1.
Weight gain (WG), specific growth rate (SGR), feed efficiency (FE), protein efficiency ratio (PER) and survival of juvenile eels fed the experimental diets for 12 weeks are shown in Table 2.
Growth and feed efficiency were monitored in terms of the final weight, weight gain (expressed as the percent of initial body weight at the end of the experiment), specific growth rate (SGR) [In (final body weight) - In (initial body weight)/time, where In = natural log, expressed as % per day), feed conversion ratio (FCR) (feed fed /wet weight gain), protein efficiency ratio (PER) (wet weight gain/protein intake), protein retention efficiency [(final whole body protein - final body weight) - (initial whole body protein - initial body weight)/total protein intake] and energy retention efficiency [(final whole body energy - final body weight) - (initial whole body energy - initial body weight)/total energy intake].
The cumulated weight gain, feed conversion ratio, energy efficiency ratio (ME intake (kcal)/weight gain (g)), protein efficiency ratio (weight gain (g)/protein intake (g)) data were calculated for the entire experiment period.
05) difference in specific growth rate, protein efficiency ratio, protein productive value, lipid productive value, energy productive value and FCR between control diet and Diet 2, and SBM can be used up to 40% in rainbow trout growth rations.
Calculation was made as follows: specific growth rate (SGR) = 100 x [(lnWf - lnWi)/t], feeding rate (FR, % body weight/day) = 100xC/{[(Wi + Wf)/2]/t}; feed efficiency ratio (FER) = (Wf - Wi)/C; protein efficiency ratio (PER) = (Wf Wi)/Cp, where, Wi and Wf are initial and final weights, t is feeding duration (days), C is feed consumption (g) and Cp is protein consumption (g).
