this study was conducted to evaluate the effects of beta plus probiotic, a mixture of bacillius leicheniformic and bacillius subtilis , on the growth performance and intestinal microbial flora of caspian trout ( salmo caspius ). a basal diet was formulated and supplemented with beta plus at 0, 0.5 and 1 g kg -1 , leading to three experimental diets. each experimental diet was randomly assigned ...

the objective of this study was to evaluate the effect of five dosage of vitamin c (0, 50, 250, 750 and 1500 mg vitamin c per kg diet) on fatty acid composition of caspian brown trout fry (salmo trutta caspius). fish (initial average body weight of 0.1 ± 0.02 g) were fed by formulated diets for 6 weeks in triplicate. the findings of growth parameters and survival showed significant difference a...

a total of 240 japanese quail chicks (1 d old) were used in a 42-d trial to study the effects of artichoke leaf powder and vitamin e on growth performance and meat quality. this experiment was performed as a completely randomized design with 4 replicates of 15 quails in each, using a 4×2 factorial arrangement with diet and gender as the main effects. four dietary treatments were formulated by a...

Three feeding trials were conducted to evaluate low-gossypol cottonseed flour as a replacement for fish meal in the diet of black sea bass and southern flounder raised in RAS. In experiment 1, diets were formulated to replace 0, 50, 75 and 100% menhaden fish meal protein (FMP) by glandless cottonseed flour protein (GCP) and solvent-extracted cottonseed flour protein (SCP), and to replace 100% F...

We conducted 2 consecutive experiments to verify whether adult captive Greater rheas (Rhea americana) could select diets differing in nutritional and energetic content, and to evaluate the effect of those diets on egg production and hatchability. From August to January, animals were offered four diets: processed feed for rheas (diet 1), diet 1 + soybean (diet 2), processed feed for chicken (die...

in sea urchin C:N (R = −0.74 and R = 0.93, for diet and growth effects, respectively) and N:P ratios (R = 0.60 and R = −0.63, also, respectively, for diet and growth effects). Among potential compensatory mechanisms helping to preserve certain levels of homeostasis, ingestion rates (g WW diet per g WW of urchin) were higher for seagrass and macroalgae diets than for the nutrient-rich formulated...

Aquaculture is growing to meet the increasing demand for aquaculture products but not free of environmental impacts. One solution improve how feed are formulated, limiting impact fish production. Multiobjective (MO) formulation, which aims a compromise between lower cost and impacts, appears be promising reduce footprint The objectives this study were design an eco-friendly trout (ECO-diet) usi...

1. The effects of including copra meals from different sources in nutritionally-balanced broiler chick diets were compared. A meal screw press-expelled twice to contain 75 g residual lipid/kg produced a lower growth rate than a meal pressed once to contain 220 g lipid/kg. 2. Chicks fed copra meal at 400 g/kg diet had a higher growth rate on a diet formulated to contain 12.4 g lysine/kg and 8.3 ...

Six experiments (EXP) were conducted to evaluate growth performance of different breed crosses of broiler chicks fed diets containing soybean meal, soy protein isolate (SPI), soy protein concentrate (SPC), or rice and casein. Cornish x Plymouth Rock (C x PR; EXP 1, 3, 4, 5, and 6) or New Hampshire x Columbian (NH x C; EXP 2 and 4) cross chicks were used. The chicks were fed a corn-soybean meal ...
