supplementary feed exogenous enzymes have improved the growth rates of various food animals. in thisresearch, the effect of endofeed w, a multienzyme feed supplement, was investigated on the growth of carp.accordingly, 134 fish (33.1 ± 0.8 g) were randomly allocated to 4 experimental groups. during the first stageof the experiment (10 days), groups 1-3 received 1, 2 and 3 g endofeed w per kg di...
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...
A 10 week feeding trial was carried out to evaluate the replacement value of hatchery wastes for fish meal in the diet of laying Japanese quail (Coturnix coturnix japonica). 108 female Japanese quails (36 per treatment) were randomly allocated into 3 dietary treatments A, B and C which are fish meal (FM), whole hatchery waste meal (WHWM) and shelless hatchery waste meal (SHWM) based diets respe...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
Studies which have been done about effects of herbs on reinforcing and stimulating the immune system in aquatic against pathogens indicate their considerable impacts. Herbs usage is becoming more common because they are cheap, with no side effects for fish, human and the environment. The aim of this research is to add essential oils of eucalyptus (Eucalyptus globules) and thyme (Zataria multifl...
the present study sought to investigate the impact of using mind-mapping technique instruction on female elementary efl learners reading comprehension; it also investigated their attitudes towards using mind-mapping technique as a tool to improve their reading comprehension. this study followed a quasi-experimental design with two intact groups as experimental, and control groups. the participa...
A feeding trial which lasted for eight weeks was conducted to investigate the effects of diludine, a growth promoter, on feed efficiency, muscle structure and proximate composition of juvenile rainbow trout. Diludine was added at 0.0(D0) 0.2(D1), 0.5(D2) and 1(D3) g kg-1 to a casein-based diet, and every diet was given to the triplicated groups of juvenile rainbow trout. At the end of experimen...
