this study compared the effects of different levels of dietary fat on growth performance, liver enzymes and blood biochemical of juvenile siberian sturgeon (acipenser bearii) was designed for 12 weeks. for this reason 135 fish (15.6 ± 0.33g; mean ± sd) at nine 500 liter fiberglass tanks, each one containing 15 fish. three experimental diets with the same protein (42 %) and 3 fat levels 10, 15 a...

This paper aimed to summarize published responses to treatment of cattle diets with exogenous fibrolytic enzymes (EFE), to discuss reasons for variable EFE efficacy in animal trials, to recommend strategies for improving enzyme testing and EFE efficacy in ruminant diets, and to identify proteomic differences between effective and ineffective EFE. A meta-analysis of 20 dairy cow studies with 30 ...

Three experiments were carried out to evaluate the growth performance and breast yield of broiler chickens fed diets with increasing levels of DDGS and the additions of different enzymes to compensate the energy reduction in DDGS-added diets. In all the experiments Ross B308 male broilers were individually fed. In Exp. 1, 96 broilers from 21 to 35 d of age were used and assigned to 8 treatments...

Using of phytobiotics as fish feed additives have been interestingly increased during the recent decade. The aim of the current study was to evaluate the effect of individual and combined level of thyme and vitamin E in common carp. Juveniles were separately fed by four distinct diets including control (commercial diet without any additive), supplemented with 1% ground Shirazi thyme, supplement...

Ameliorative potential of antioxidants –vitamins C and E on blood profile of Clarias gariepinus fed diets contaminated with varied levels of fumonisin B1 (FB1) was evaluated. Fusarium cultured maize containing FB1 were used to formulate diets containing approximately 2.5, 5.0, and 7.5 mg FB1/kg constituting diets 2, 3, and 4, respectively and other nine diets constituting Diets 5 - 13 with the ...

In present study the effect of dietary inclusion of equal amounts of four traditional medicines; Matricaria chamomilla L, Zataria multiflora L, Mentha piperita L and Terminalia chebulo L on growth performance and digestive enzymes activity in Litopenaeus vannamei was investigated. Two diets, including a control basal diet and an experimental diet with 30 g kg-1 herbal mixture supplementation we...
