In recent years, questions have been raised on the possible semi-endogenous status of the alleged xenobiotic thyreostatic drug thiouracil; thiouracil has been detected in the urine of various animals (livestock and domesticated) at concentrations between 1 and 10 μg L(-1) and also in human urine. Although several studies suggest Brassicaceae-derived feed as potential origin, no traces of thiour...

BACKGROUND Distiller's dried grains with solubles (DDGS) and soybean meal were used as the substrates for the production of polyunsaturated fatty acids (PUFA) in solid-state fermentation (SSF) by Mortierella alpine. These fermented products were fed to laying hens. PUFA enrichment from chicken breasts was studied. METHODS The maximum productivity of PUFA was achieved under optimized process c...

Introduction Glucosinolates are a class of compounds found in the plant family Brassicaceae and particularly in rapeseed. They are considered as responsible for the detrimental effects (palatability and toxic symptoms) observed when rapeseed meal is used for feeding (Fenwick et al., 1983). The analysis of glucosinolates appears to be a good evaluation of rapeseed anti-nutritional potential. Dur...

Rapeseed is the second largest plant protein resource in world with an ideal profile of essential amino acids. meal (RSM) one by-products rapeseed oil extraction. Due to anti-nutritional components (glucosinolates and fiber) poor palatability, RSM limited livestock diets. Recently, how decrease factors improve nutritional value has become a hot topic. Therefore, major have been reviewed emphasi...

Yeast strains and appropriate hydrolysis conditions were selected for efficient single cell protein (SCP) production from waste rapeseed meal. High potential effective biomass was observed Yarrowia lipolytica LOCK0264 with 10 g of meal at 4.9 × 108 ± 1.5 (2.91 logarithmic units). The highest yeast multiplication rate obtained Metschnikowia pulcherrima NCYC747 12.5 15 1.6 3.8 107 4.5 4.0 (2.75 2...
