1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
The effect of different levels of vitamins C and E on growth survival and blood factors were studied on common carp (Cyprinus carpio). 9 mixed diet containing 0, 200 and 400 mg / kg of vitamin C and0, 200 and 400 mg / kg vitamin E for 6 weeks were performed in triplicate. Total of 270 common carp with an average weight of 12.29 g were introduced into the 27 number of rearing tanks. At the end o...
The aim of this study was to evaluate the effect of different levels of organic and mineral sources of selenium on the intestinal morphology and also histologically changes in liver tissues of juvenile rainbow trout for 60 days. For this purpose, 1080 healthy fry fish (50±2.8 g average body weight) were randomly divided into 3 groups, including organic selenium (0.15, 0.30, 0.45, 0.60 mg. kg-1)...
abstract the primary purpose of this study was to explore the actual practices and cognitions of two groups of iranian eap teachers, i.e. language teachers and content teachers, with respect to teaching reading-comprehension and vocabulary. to this end, tehran university of medical sciences which authorizes both groups of teachers to teach eap courses was selected as the context of the study s...
Salinity stress is one of the marked influencing factors on ecophysiology aquaculture and considered an important reason for retreat fish industry. The current study endeavor to elucidate molecular mechanisms that underlie response salinity in common carp. Fish (Average weight 5 ± 2 g) were randomly distributed into two groups; 1 st a control was exposed tap water (0.2 ppt salinity) nd treated ...
In this study, the essential oil (EO) of Pistacia atlantica subsp. kurdica was added at the rate of 10 g/kg of daily diet of rainbow trout and its effect on gut microbiota (Enterobacteriaceae, Lactobacillus spp., total count), growth performance and antioxidant status of rainbow trout fillet was investigated. Sixty apparently healthy rainbow trout with an approximate weight of 150 g ±3.5 were r...
A killifish species Aphanius ginaonis occurs in Geno hot spring is one of the unique fish species that could successfully survive and acclimated to the high temperature of hot springs. In this study, we investigated the effects of Geno's cyanobacteria extracts on growth, survival and morphology of gill tissue in Aphanius dispar exposed to normal temperature and long-term thermal stress. For thi...
PURPOSE To evaluate the antioxidant and antiperoxidative effects of oil mixes of high ratio Omega-9:Omega-6 and low ratio Omega-6:Omega-3 in the third day after tooth extraction in rats. METHODS Thirty-two male Wistar rats (270-310 g) were randomly distributed in two groups: Control (n=24) and Test (n=8). Control group was divided into three subgroups (n=8): G1: Sham-Saline; G2: Saline; G3: I...
this study was carried out to determine the effects of immunogen as a prebiotic on growth-related parameters and gut micro-flora in r. kutum fry. a basal diet was formulated using common feed ingredients supplemented with immunogen at 0, 1, 1.5, and 2 g kg-1 leading to four experimental diets. fish were randomly distributed in 500 l fiberglass tanks (1×1×0.5 m). the experiment lasted for eight ...
the aim of this study was to determine the effect of propolis and pollen extract on biochemical and haematological parameters of onchorhynchus mykiss. one hundred and eighty healthy fish, o. mykiss (mean weight 20.57±4.48 g) were used for growth performance and haematological assays. they were randomly selected, and distributed among fifteen 600-l fiberglass tanks as three treatments (1% polle...
