in order to study the effect of different levels of β-mannanase enzyme on the performance, blood parameters and carcass characteristics of broiler chicks (arbor acres), an experiment was conducted with 240 checks (44.6 grams average weight) under a completely randomized design with 4 treatments and 5 replications and 12 checks per each replicate. β-mannanase enzyme with the levels of zero (t1 c...
The current study aimed to evaluate effects of four levels (0, 2, 4 and 6 % of diet) of soybean lecithin in the isoproteic and isoenergitic (50% protein and 18.5 kj/g) diets on growth performance, feed utilization and hematological parameters of juvenile sobaity seabream (Sparidentex hasta) with initial weight of 37.9±0.16 g. At the end of 56 days of feeding trial, results showed that growth pe...
The study was conducted to compare the efficiency of diets containing various levels of calcium(0, 1, 2, 3 and 4 percentage) in feeding freshwater crayfish, Astacus leptoductylus. 150 cray fish (10 individuals per tank) with mean weight of about 8-9 gram were stocked in each of 15 tanks, containing 100 L of water. In this research, The results showed that the mean values of some parameters such...

Infant body composition and postnatal weight gain have been implicated in the development of adult obesity and cardiovascular disease, but there are limited prospective data regarding the association between infant adiposity, postnatal growth and early cardiovascular parameters. Increased aortic intima-media thickness (aortic IMT) is an intermediate phenotype of early atherosclerosis. The aim o...
The aim of the present study was to evaluate the effects of dietary Guava (Psidium guajava) leaves powder (GLP) on growth parameters, feed utilization as well as some serum parameters of common carp (Cyprinus carpio) fingerlings. Common carp fingerlings (18.88±0.27 g) were supplied and stocked in twelve fiberglass tanks at density of 14 fish per tank. Fish were fed experimental diets contains 0...
Lactobacillus casei probiotic is one of the probiotics used in aquaculture industry. The aim of this study was to evaluate the effect of Lactobacillus casei probiotic on the growth performance, blood parameters, and intestinal microbial flora in goldfish (Carassius auratus) for 60 days. In this study, 180 fish with an average weight of 10.11± 0.16 g were randomly distributed into two treatments...
growth rate of 60 lori-bakhtiari single male lambs were assigned to a completely randomized design with two factors. the factors were tail status (with and without fat tail) and fattening period ( 75,90, 105 days). lambs were alternately docked by the use of rubber rings at the begining of the second day of birth. lambs were weaned at 90±5 days of age and randomly divided into three groups...
