 Best diet of the fish is the sole of production of aquaculture. Growth performance of Clarias gariepinus on the basis of formulated feed supply was carried out from 7th March to 6th May, 2019 in the laboratory of P.G.Campus, Biratnagar in which 130 juveniles (each of 10±0.11 g.) of catfish were cultured in 13 aquaria feeding with treatment diets having crude protein level 35%, 40%, 45% and 50% for treatment and commercial diet for control. There are no significant differences between the water quality parameters and body weight gain (p>0.05) in all treatments. The highest body weight gain (7.31±0.11 g; 65.20%) and SGR (13.051±1.15 g) was observed in fish fed with T C (45% protein level). This value was lowered than value of control(C) i.e. 7.59±0 g; 69.88% and 13.55±0 g respectively. Feed conversion ratio (FCR) was best (13.28±1.89 g) in T D (50% protein level feed). Its value was larger (7.52±1.11 g) in T C than C (7.15±0 g). Mortality rate was highest in T C and C i.e. 30% and lowest in T A and T B i.e. 23.33%. Weight gain of the fish increased with increasing protein level in diet till crude protein level 45% then it was dropped at the diet with protein level 50%. The best weight gain was observed in 7th week having crude protein level 45%. The diet with protein level 45% is suggested for farmers concerning the fish (Clarias gariepinus) in the aquaculture.

Purpose: This article aims to evaluate the effect of dietary protein levels on growth performance and some blood biochemical composition of male Japanese quail. Study Design: Qualitative Descriptive Design. Subjects and Methods: Three hundred, three week old apparently healthy male Japanese quail were used in this experiment. The birds were randomly allocated into 5 groups with 3 replicates of 20 birds for 21 days of experimental period and placed in cages, measuring 100 cm (length) x100 cm (width) x 80 cm (height). Group A was fed on diet 1 containing 18% crude protein, Group B was fed on diet 2 containing 20% crude protein, Group C was fed on diet 3 containing 22% crude protein, Group D was fed on diet 4 containing 24% crude protein and Group E was fed on diet 5containing 26% crude protein. All groups were subjected to similar management practices. Results: The findings showed that growth performance parameters significantly improved as dietary crude protein level increased. However dietary protein level beyond 22% has no beneficial effect on growth. Biochemical examination results demonstrated that the crude protein level in diet was not significantly affected the blood glucose, cholesterol,   bilirubin, calcium, phosphorus and liver enzyme activities (ASAT and ALT). However, we noticed a significant effect (P<0.05) about Total protein, Albumin, Urea, Triglycerides, Creatinine and Uric acid. Despite the variation of these parameters, they remain within the normal range. Conclusion: Therefore, it is concluded that dietary protein levels do not affect quail health. The crude protein requirement for Japanese quail from 21 to 42 days old is 22%.

Abstract Background The reduction of crude protein levels in diets for broiler chickens may generate economic, environmental and flock welfare and health benefits; however, performance is usually compromised. Whole grain feeding and phytase may improve the utilization of reduced crude protein diets. Results The effects of pre-pellet cracked maize (0, 15% and 30%) and phytase (0, 750 and 1500 FTU/kg) in iso-energetic maize-soy diets with three levels of crude protein (22%, 19.5% and 17%) were evaluated via a Box-Behnken response surface design. Each of 13 dietary treatments were offered to 6 replicate cages (6 birds/cage) of male Ross 308 broiler chicks from 7 to 28 d post-hatch. Model prediction and response surface plots were generated from experimental data via polynomial regression in R and only significant coefficients were included and discussed in the predicted models. Weight gain, feed intake and FCR were all influenced by pre-pellet cracked maize, phytase and crude protein level, where crude protein level had the greatest influence. Consequently, the reduction from 22% to 17% dietary crude protein in non-supplemented diets reduced weight gain, feed intake, relative gizzard weight, relative gizzard content and relative pancreas weight but improved FCR. However, the inclusion of 30% cracked maize to 17% crude protein diets restored gizzard weight and 1500 FTU phytase inclusion to 17% crude protein diets increased relative gizzard contents and pancreas weights. Cracked maize and phytase inclusion in tandem to 17% crude protein diets increased weight gain, feed intake and FCR; however, this FCR was still more efficient than broilers offered the non-supplemented 22% crude protein diet. Broilers offered the pre-pellet cracked maize and phytase inclusions reduced AME in 22% crude protein diets but improved AME by 2.92 MJ (14.16 versus 11.24 MJ; P < 0.001) in diets containing 17% crude protein. Ileal N digestibility was greater in broilers offered diets with 17% crude protein than those offered the 22% crude protein diet; irrespective of phytase and pre-pellet cracked maize. Conclusion Pre-pellet cracked maize and phytase inclusions will improve the performance of broilers offered reduced crude protein diets.
