“…This is because choline from choline chloride is readily absorbed in the small intestines, but there may be no or very low bacteria‐derived enzymatic breakdown of sinapine into choline in the small intestine (Qiao & Classen, ), limiting its absorption. Higher bacteria populations in the distal gut break down sinapine into choline, increasing its availability for bacterial fermentation (Goh, Mueller, Clandinin, & Robblee, ). Trimethylamine is a malodorous compound that is oxidized into an odourless trimethylamine oxide (TMAO).…”

De‐oiled (<10 g/kg oil) carinata (Brassica carinata) meal is high (>400 g/kg) in protein, but its use in fish diets will likely be limited mainly by glucosinolates (GLS), sinapine and crude fibre. Two feeding experiments were conducted to determine the response of hybrid striped bass (Morone chrysops ♀ X M. saxatilis ♂, HSB) to inclusion of cold‐pressed carinata meal (CPCM) in diets. Cook extrusion reduced an average of 44% and 57% of GLS and sinapine concentrations in diets, respectively. In experiment 1, diets containing 0.71–2.71 μmoles of GLS and 0.034–0.181 mg of sinapine/g did not significantly (p > .05) reduce feed consumption, utilization or growth, resulting in similar concentrations of thyroxines and consequently no effect on deiodinase enzymes. In experiment 2, there was a significantly reduced (p < .05) feed consumption in fish fed diets containing 5.58–9.52 μmoles of GLS and 0.54–0.75 mg of sinapine/g, resulting in HSB exhibiting lethargic swimming and feeding behaviours, and consequently poor feed utilization and growth. Cook extrusion reduced about half of GLS and sinapine, and HSB tolerated ≤2.71 μmoles of GLS and ≤0.31 mg of sinapine/g of diet without affecting feed consumption and utilization, growth and thyroid metabolism.

Rapeseed meal and egg taint: The role of sinapine

Agricultural Research Council Food Research Institute, Colney Lane, Norwich, Norfolk NR4 7UANeither the administration of sinapine bisulphate in the diet, nor the repeated intramuscular or intravenous injection of large doses of this substance, reduced the ability ofchicks or laying hens to oxidise trimethylamine (TMA), as measured by the activity of TMA oxidase in hepatic microsomes or the amounts of 14C-TMA oxide that appeared in the plasma after the infusion of a standard dose of 14C-TMA. Thus, in contrast to its behaviour in vitro, sinapine did not produce significant inhibition of TMA oxidase under these conditions. Since the amount included in the diet was similar to that which would be provided by a diet containing 10% rapeseed meal, it was concluded that sinapine is not involved in the depression of TMA oxidation that occurs when the meal is fed and acts solely as a source of TMA in the consequent production of egg taint.

Trimethylamine taint in eggs: The occurrence of the causative metabolic defect in commercial hybrids and pure breeds in relation to shell colour

1984

Six commercial foundation flocks (Rhode Island Red, New Hampshire Red and White Leghorn hybrids) and four pure breeds (Rhode Island Red, Light Sussex, White and Brown Leghorns) were included in a survey which was carried out to facilitate the elimination of the tainting defect from commercial stock by selective breeding. The defect results from an inherited inability to synthesise adequate amounts of trimethylamine (TMA) oxidase, and was detected by estimating the activity of the enzyme in the livers of young chickens, or by measuring the amount of [14C]-TMA oxide in the plasma after the injection of [14C]-TMA. It was present in two of the brown-egg breeds (Rhode Island Red and Light Sussex) and in one of the white-egg breeds (Brown Leghorn), and therefore was not associated with shell colour. There was no significant correlation between depth of shell colour and TMA oxidase activity in a commercial Rhode Island Red flock.
