An experiment was conducted to evaluate the effects of biogen probiotic additives on growth performance of common carp, Cyprinus carpio. Four practical diets containing 0 (control) , 0.1, 0.2 and 0.3 % Biogen probiotic were used to feed fish. Seventy-two juvenile common carp (65 ? 3.5g) were randomly distributed between 12 fiberglass tanks of 500 L capacity. During 60 days of feeding trial, the...

Six hundred day old unsexed broiler chicks were used in a 42-d trial at Chittagong Veterinary and Animal Science University Poultry Farm to compare the effects of different levels of fish oil supplementation on performance of broilers in terms of feed intake, weight gain and feed conversion and carcass characteristics. The chicks were randomly distributed following a completely randomized desig...

Sixty medium-framed Hereford steers averaging 243 kg were used in an experiment including a growing period (28 wk) and a finishing period ending when the animals had approximately 4 to 10 mm of fat thickness (Canadian grade A1). Steers were assigned randomly to a 2 x 3 factorial arrangement of treatments for 28 wk (growing period). From the end of the growing period until slaughter, all steers ...

Invasive species can have negative effects on native biodiversity and ecosystem function, suppression is often required to minimize the effects. However, management actions suppress invasive may cause negative, unintended non-target taxa. Across United States, lake trout (Salvelinus namaycush) are in many freshwater ecosystems, reducing fish abundance diversity through predation competition. In...

A total of 270 fingerlings of Asian sea bass (Lates calcarifer) were allotted into three equal treatments with three equal replicates for each to investigate the effect of dietary supplementation of two levels of Black cumin seeds (Nigella sativa) and Turmeric (Curcuma longa) mixture (BTM) on growth performance and blood chemistry throughout the experimental period (98 days). Fish of the first ...

The authors investigated the kinetics of transfer of perfluorooctane sulfonate (PFOS) from water, suspended sediment, and bottom sediment to a marine benthic fish, the marbled flounder (Pseudopleuronectes yokohamae). Fish were exposed in 3 treatments to PFOS in combinations of these exposure media for 28 d and then depurated for 84 d. A major part (37-66%) of PFOS in the fish was in the carcass...

The effects of carnitine were evaluated in diets fed to hybrid striped bass. The basal diet contained 34.6% crude protein supplied by casein, gelatin and crystalline L-amino acids and 6.0% lipid supplied by menhaden oil. Four dietary treatments contained L-carnitine concentrations of either 2.1, 41.0, 212.0 or 369.7 mgrkg diet. Dietary treatments were fed to apparent satiation twice daily to tr...
