in this study, two main probiotics (lactobacillus plantarum and lactobacillus delbrueckii subsp. bulgaricus) were isolated from the intestine of tor grypus and their effects on growth performance, gut microbial flora and digestive enzymes activities (i.e., α-amylase, lipase, trypsin, chymotrypsin, and alkaline phosphatase) of tor grypus (karaman, 1971) were determined. juveniles of t. grypus (n...
Thyroid hormones [Triiodothyronine (T3) and thyroxine (T4)] are also known to play an important function in biological processes such as growth, sexual development, osmoregulation, metamorphosis, temperature tolerance, migration, oxygen consumption, and metabolism in different fish species. The objective of this study was to examine the effects of T4 injection on growth performance, and reprodu...
introduction bean (vicia faba l.) has the great old history of crop cultivation to date would be pushed back to a fairly long day plant, resistant to frost and cool season crop and up to 5 degrees celsius tolerated. bean prefers wet and cold conditions. excessive heat may cause fetal growth problems, loss and reduce the number of seeds per pod bean flowers to the growth of plant and fruit set o...
effect of different photoperiodic regimes was evaluated on growth performance and survival rate of the beluga ( huso huso ) prelarvae and larvae. newly hatched prelarvae were stored in 5 round fiberglass 500‑l tank with different photoperiod (24l:00d, 18l:06d, 12l:12d, 06l:18 d, 00l:24d) till 50 days post hatch with three replicates. light intensity was 200 lux during the experiment. feeding wa...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
The objective of this study was to investigate the effects of different early weaning programs on growth performance and blood parameters of dairy calves. To meet this objective, thirty Holstein calves with initial body weight of 36 ± 5 kg were randomly assigned at birth to one of the three weaning programs. Experimental groups were: 1) starter diet and whole milk from birth to 6 weeks and wean...
Moringa oleifera commonly referred to as the drumstick tree is a plant from the Moringaceae family. It is a medicinal plant that was found to be loaded with different bioactive chemicals or secondary metabolites such as vitamins, minerals, saponins, alkaloids, flavonoids, carotenoids etc. which are involved in enhancing a long term health benefits. M. olifera is among the most promising species...
This study evaluated the effects of artichoke leaf powder on growth performance and physicochemical properties of Japanese quailfrozen meat after 3 monthstorage. A total of 240 Japanese quail chicks (1 d old) were raised over a 42-d experimental period. The experiment was performed as a completely randomized design with 4 replicates of 15 quails in each, using a 4 × 2 factorial arrangement with...
