A 2 × 3 factorial experiment was conducted to investigate the effect of enzyme Endofeed W (EEW) at 0 and 0.05%, thyme essential oil (TEO), probiotic Primalac® (PP) and non-feed additive, on intestinal histomorphology of broilers fed wheat-based diet. Each of the 6 dietary treatments was replicated 4 times with 12 chicks each from 0 to 42 days of age. There was no interaction between enzyme and ...

Arsenic is a kind of necessary trace elements of livestock and poultry nutrition, and plays an important role in the tissues and organs and metabolism, etc. With the rapid development of feed industry, the organic arsine preparations of feed additives have been widely applied in animal husbandry. But these organic arsine preparations are absorbed less in animal body, and large amount of them ar...

Biomass of Kluyveromyces marxianus was used to prepare feed formulations for ornamental fish-black mollies (Poecilia latipinna). The cytotoxicity of the fungal biomass was studied using 3T3 cell lines. Three different formulations of the biomass were used in the feeding trial. Formulation I was prepared as 100% dry cells, formulation II was prepared as 50% dry cells+50%starch and Formulation II...

Polycyclic aromatic hydrocarbons (PAHs) and heavy metals contribute to pollutants in aquaculture facilities and thus need to be further investigated. Besides, there is little information regarding PAHs and heavy metals in the tissues of cultured fish, and the risks associated to consumption. In this review, emphasis has been made on the detection of PAHs and heavy metals in cultured fish specie...

A new method for rapid sampling and qualitative characterization of the headspace gases of closed in vitro cultures using solid phase microextraction (SPME) was evaluated for ruminal fluid and ruminal fluid with feed containing a feed additive. Gas sample collection was achieved by exposing a DVB/Carboxen/PDMS 50/30 m SPME fiber to the headspace of cultures for 1 min every hour. This was follow...

A feeding trial was conducted for 75 days to study the effects of live brewer’s yeast (Saccharomyces cerevisiae) on growth and body composition in post larvae of the giant freshwater prawn, Macrobrachium rosenbergii (de Man). Five diets were formulated containing optimum protein level of 35.24±0.04. These experimental feeds were supplemented with 0.0% (control diet), 0.1%, 0.2%, 0.5% and 1.0% l...

In the first study, we tested the ability of a commercial feed additive (OmniGen-AF) to affect markers of innate immunity in immunosuppressed sheep and the ability of a pathogen challenge (mould) to affect the immune response to the additive. Treatments consisted of (1) control, (2) immunosuppressed with dexamethasone (DEX), (3) immunosuppressed plus the feed additive, (4) immunosuppressed plus...

this present study was conducted to evaluate the effects of dietary inclusion of 4, 8 and 12 g kg-1 phytogenic feed additives mixture on performance, egg quality, ovary parameters, serum biochemical parameters and yolk trimethylamine level in laying hens. the results of experiment have shown that egg weight was increased by supplementation of 12 g kg-1 feed additive whereas egg production, feed...
