In vitro interactions of malachite green and leucomalachite green with hepatic drug-metabolizing enzyme systems in the rainbow trout (Onchorhyncus mykiss).

Malachite green (MG) has been widely used in aquaculture to treat a number of microbial and parasitic diseases. It is currently banned in the EU because of the high cytotoxicity and carcinogenic activity, which is also shared by leucomalachite green (LMG), a reduced MG metabolite that can persist in fish tissues for months. There is scant information about the ability of either compound to interact with drug metabolizing enzymes in fish.

Inclusion of bilberry pomace in rabbit diets: Effects on carcass characteristics and meat quality.

A trial was performed to evaluate bilberry pomace (BP) as alternative source of nutrients for rabbits. One hundred and forty-four Grimaud weaned rabbits were divided into 4 groups of 36 animals each and fed ad libitum with a basal diet (BP0) tested against three assay diets developed by substituting 50, 100 and 150g/kg of the BP0 diet with BP (BP5, BP10 and BP15 diets, respectively). Carcass characteristics of rabbits were not affected by treatment, with the exception of liver weight.

Gene expressions and metabolomic research on the effects of polyphenols from the involucres of Castanea mollissima Blume on heat-stressed broilers chicks.

To study the effects of polyphenolic extract from involucres of Castanea mollissima Blume ( PICB: ), a novel approach using gene expression by real time polymerase chain reaction ( REAL-TIME PCR: ) coupled with metabolomic profiling technique was established to explain the mechanism of PICB on heat-stressed broiler chicks. Four thousand 28-day-old male Arbor Acres (AA) broilers were randomly assigned to 5 groups (4 replicates / group, 20 chicks / replicate), in which group 1 was normal control group fed with basic ration; groups 2, 3, 4, and 5 were fed with the basic ration with a supplementation of 0.2% Vitamin C ( VC: ), or 0.

Effects of chestnut tannins on carcass characteristics, meat quality, lipid oxidation and fatty acid composition of rabbits.

Seventy two male Bianca Italiana rabbits were used to study the effects of the inclusion (0%, 0.5%, and 1.0%) of a natural extract of chestnut wood (Silvafeed ENC) in the diet on productive traits, carcass characteristics, meat quality, lipid oxidation and fatty acid composition of rabbit meat.
