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...

proper feeding is necessary to have appropriate growth, health and also to increase resistance to inappropriate condition such as stressors and diseases. therefore mineral and vitamin supplements are added to fish diet to improve its growth and health. food supplements have different roles in diet. these cause better food metabolism, higher hardness and strength of bones, better ionic exchanges...

The effect of feed supplemented with L-camitine at four levels of 0, 300, 600 and 900mg kg-1 on growth performance and body composition of beluga, H. huso, juveniles was evaluate din two separate trials. In the first trial, 180 juveniles (525±9gw) were fed with the test diet for a period of 71 days, and the trial extended to another 126 days in the second phase by randomly selecting 120 juvenil...

In Gucheng Lake, Jiangsu Province, China, randomly selected crabs were fed 2 diet types. Crab crude oil methyl ester analysis was performed using gas chromatography-mass spectrometry. Fatty acid compositions in the 3 edible parts of a crab - the hepatopancreas, gonad, and muscle - were analyzed. C16:1 and C18:2 were significantly higher in most commercial pellet feed-feeding crabs than in small...

An experiment was conducted to observe growth performance and survival of the larvae produced from the brood fish of Ompok pabda treated with 4 dietary levels of vitamin E for 90 days viz. 0 (served as control), 50, 100 and 150mg vitamin E/kg feed under 4 treatments i.e. treatment T1, T2, T3 and T4. After the feeding trials, the brood fish were induced to breed with equal dose of PG extract i.e...

A research study was conducted to investigate the culture possibility of fresh water catfish Pangasius pangasius with formulated feed in natural ponds. The stocking density was chosen as 8000 fry/ha with an initial weight of 42.57+ 2.51 g. The formulated feed contained 45% fishmeal, 30% mustard oil cake, 15% wheat bran and 10% rice bran to supply 40.48% protein in feed. The growth of Pangasius ...

“Pink spot” disease of Porites corals is caused by infection by the digenetic trematode* Podocotyloides stenometra. The pink spots are individual coral polyps which have been infected by immature stages of the parasite, which form cysts inside the coral tentacles and cause the polyp to swell and become pink colored. One step in the very complex life-cycle of this parasite occurs when a fish fee...

Effects of dietary Scutellaria baicalensis extract (SBE) on growth, feed utilization and challenge test of olive flounder (Paralichthys olivaceus) were determined. Six hundred thirty fish averaging 5.0 g were distributed into 18, 180-L tanks. Six experimental diets were prepared in triplicate: SBE-0, SBE-0.5, SBE-1, SBE-2, SBE-3 and SBE-5 diets containing SBE at the concentrations of 0, 0.5, 1,...

Broiler chicks were fed a diet containing 4% of either corn oil or fish oil from 3 to 14 d of age. From Days 15 to 23, half of the chicks in each dietary treatment were fed Lofrin (an experimental 5-lipoxygenase inhibitor) at 33 micrograms/kg feed. The remaining chicks within each dietary treatment were the untreated controls. At 24 d of age, half of the chicks within each diet-Lofrin treatment...
