the acehnese mahseer, locally known as keureling, tor tambra is one of the highest economically valued freshwater fishes found in aceh waters. the culture of t. tambra was initiated in aceh province, indonesia more than five years ago. however, the growth rate in captivity has been low, probably due to feeding problems. hence, the objective of the present study was to evaluate the optimum level...
The aim of this study was to investigate the effect of different dietary protein levels on growth, survival and body composition of Hediste diversicolor. Three isocaloric diets with three different protein levels containing high protein (50%), medium protein (35%) and low protein (20%) were designed in three replicates in completely randomized design. Hediste worm larvae weighing 0.02±0.005g we...
background: mixed cereals and legumes products enhance protein quality. this study has been conducted to compare the protein value of two homemade foods (a mixture of beans and rice and a mixture of vetch and rice) with a commercial baby food (wheat- based cerelac) in rats. methods: an experimental study has been conducted on 80 male rats, which divided into 8 subgroups. five different diets in...
in this thesis protic and aprotic ammonium-based ionic liquids were synthesized and their surface tensions were measured in the range of 298-373k. the protics are alkyl ammonium-based ils with the carboxylate (formate, acetate, propionate) anion and aprotics are quaternary ammonium-based ils with bis(trifluoromethylsulfonyl)imide anion. capillary rise method was used for surface tension measure...
The effects of dietary protein levels were investigated on growth, carcass biochemical composition and apparent digestibility coefficient in Caspian trout, Salmo trutta caspius. The present study was carried out in a completely randomized design with five experimental diets containing five different dietary levels of protein: 35, 40, 45, 50 and 55%, and 15 fish per replication of each with an i...
overall energy efficiency (oee) is an important indicator of energy consumption in tillage operations. tillage energy was studied objectivity to accurately measure the oee of mf399-4wd tractor. the tractor was equipped with different types of sensors to measure and calibrate the required data including: fuel consumption, actual forward speed, wheel speed and slippage, engine speed, draft and dr...
l- carnitine has been recognized as a new and important dietary supplementation, essential for human and animal nutrition. this study was conducted to evaluate the use of dietary l- carnitine supplementation and its effects on the growth (body final weight, daily growth rate (dgr), feed efficiency (fe), feed conversion ratio (fcr), daily feed intake (dfi), protein efficiency ratio (per), lipid...
A 50-day feeding trial was conducted to evaluate the effects of yeast nucleotide in diets on growth performance, serum immune indices and muscle composition of Ancherythroculter nigrocauda (mean initial body weight, 23.30±0.59 g). Seven isonitrogenous (approximately 42.76% crude protein) and isoenergetic (17.43 KJ g−1 gross energy) experimental diets with varying levels of yeast nucleotide (0[c...
the our purpose of objective is evaluation and comparison the energy flow in wheat lands of cities in alborz province. we try to calculate the indexes of energy ratio, gross energy, specific energy, energy efficiency, energy intensity, total input and output energy. population of the study consisted of farmers of cities in alborz province in the year of 1391-92. it was a best way that we use po...
