A simple measure for the efficiency of protein synthesis by ribosomes is provided by the steady state amount of protein per messenger RNA (mRNA), the so-called translational ratio, which is proportional to the translation rate. Taking the degradation of mRNA into account, we show theoretically that both the translation rate and the translational ratio decrease with increasing mRNA length, in ag...

A series of two experiments was conducted to study the optimum dietary protein level and protein to energy ratio of lemon fin barb hybrid larvae. In Experiment 1, five isocaloric diets (4700 kcal per kg) ranging from 40 to 60% protein in 5% increments were fed to triplicate groups of lemon fin barb hybrid larvae (initial weight: 0.10 ± 0.01 mg per fish) for 21 days. Weight gain of fish was prop...

The effects of two diets, a control diet (commercial feed with 39% crude protein) and an experimental diet (prepared based on 42% soybean meal with 38% crude protein), on growth performance of western white shrimp (Litopenaeus vannamei) in six 0.4-ha-earthen ponds (three replications per treatment) with 25 per m2 density, were investigated. There was no significant difference in final weight (m...

the price of water in agriculture plays an important role in the water allocation management. therefore, the optimum strategies of cropping pattern could be designed when water price analysis are considered in a predetermined economic framework. in the present study, a programming model was developed using the genetic algorithm for optimal water allocation in the eastern north of khuzestan prov...

Abstract For the proper growth of fish, it is necessary to feed fish with a and balanced diet. A study was conducted find out effect different protein-based diets on fingerlings Tor putitora (mahseer). dietary protein levels 35%, 40%, 45%, 50% were prepared. The weight gain, standard rate (SGR), food conversion ratio (FCR), percent efficiency (FCE), (PER) studied. An increase observed in an con...

to evaluate the value of random urinary protein creatinine ratio in prediction of 24h proteinuria in hypertensive pregnancies. method: random urine samples and routine 24h urine collections were collected from hypertensive pregnant women (n=100). reliability of random urinary protein-creatinine ratio was assessed by receiver operator characteristic (roc) curve to detect significant proteinuria ...

Objective: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks.  Methods: The protein quality of earthworm meal was evaluated and compared to that of soybean meal (SBM) in two experiments using broiler chicks. Results: The results of experiment 1 indicated that there were no significant differences between earthw...

this study evaluated the effects of 0.25% activated charcoal added to sesame seed meal (ssm) in partial replacement of soybean meal (sbm) of juvenile clarias gariepinus diet on growth and haematological parameters for 70 day experimental period. six experimental diets were formulated as: control diet 1 (100% ssm without activated charcoal), control diet 2 (100% ssm plus 0.25% activated charcoal...

With the aim of finding whether the in vitro microbiological test of Ford (1960) could be used to assess the nutritional value of the protein in meat meals processed in different ways, we have investigated seventeen samples, using both a microbiological method and a measure of protein efficiency ratio (PER) determined with the rat. This is an extension of our earlier study with fish meals (Ferr...
