Reducing dietary protein content in fish feeds will reduce cost of production if growth performance can be maintained. In this study, we assessed the effects of reduced dietary protein content from 33.5% to 27.4% with ideal amino acids profile on the growth, immune parameters, intestinal microvilli length and total ammonia nitrogen discharge of tilapia. After 8 weeks of feeding, growth performa...

A 56 days grow-out experiment with three protein levels (35, 40 and 45%) and three lipid levels (5, 10 and 15%) was conducted to evaluate the optimum protein to lipid ratio for oriental river prawn (Macrobrachium nipponense). Four hundred and five prawns, with mean (± SD) weight of 1.40 ± 0.04 g were distributed in 27 glass aquaria and were fed four times daily. Results showed tha...

Gamma irradiation was used at different doses (80, 160 and 240 Gy) on Glycine Max (L.) Merrill cv. Hill homogenous seeds. A single suitable M2 plant was selected and evaluated at M3 and M4 along with its parent and three other varieties as control in RCBD experiment in Sari Agricultural Sciences and Natural Resources University’s experimental field. M-8...

soy protein concentrate (spc) is a functional and nutritional product which is produced under conditions where soy proteins are immobilized in soy flour and soluble carbohydrates are removed. in this study, four different soy flours including defatted soy flour (fat content 3.67, pdi 55.10), defatted and toasted soy flour (fat content 3.78, pdi 10.72), low fat soy flour (fat content 14.34, pdi ...

A thermoplastically extruded snack was produced from different blends of corn grits and silver carp minced meat. Response Surface Methodology (RSM) was used to study the effect of fish meat content and to optimize the feed composition. Fourteen treatments from central composite design considering minced fish content (0-3 kg) and corn (7-10 kg) were used as the independent variables. The expansi...

a total of 153 samples of milk were collected from one to none months lactating mothers age 17 to 44 years. the protein, total nitrogen, fat, lactose and calcium content 0f these milks were determined. marked individual variation existed in the protein lactose and fat content of the milks, which was in agreement with finding of other investigators. a gradual decrease was noticed in the protein ...

an experiment was conducted in the experimental field of seed and plant improvement institute in karaj for three consecutive cropping seasons, 2001-2003, to study the effects of eight different fertilizer treatments including some microelements on grain yield and protein content of a bread wheat cultivar pishtaz. the experiment was in a rcbd with three replications.eight fertilizer treatments w...
