In order to study the effects of aromatic choline esters, thirty Texel, Suffolk or crossbred lambs allocated to three groups are fed ad libitum with pasture hay and diets containing 0 % (control) or 25% of each rapeseed meal. A specific technique is developed for trimethylamine determination in plasma. [less ▲]

Glucosinolates metabolites in plasma, milk and thyroid of gestating and lactating ewes

The effects of high level of rapeseed meal in the diet on the concentration of antinutritional factors (glucosinolates metabolites) in blood plasma, milk and thyroid were studied in 90 ewes. From the 100th day of gestation, ewes bearing two foetuses were divided into three groups and were fed with pasture hay ad libitum and 500 g/d of diet containing 0 or 40% rapeseed meal obtained from either Apex or Synergy variety. During the 47 first days of lactation, 1200 g/d of the same meal were given. Thereafter, during 3 weeks, the ewes were only fed with hay. Blood and milk samples were taken fortnightly for the determination of SCN- and 5-vinyl-1,3- oxazolidine-2-thione (5-VOT) concentrations. One ewe from each group was slaughtered at the end of rapeseed meal distribution and another one three weeks later for thyroid analyses. SCN- and 5-VOT concentrations in blood plasma increased significantly (P<0.05) and regularly until one month of rapeseed supplementation to the withdrawal of rapeseed in the diet. One to three weeks after the end of rapeseed meal distribution, the SCN- and 5-VOT plasma concentrations came back at the basal level. Some changes were also observed for SCN- and 5-VOT contents in milk. The results indicated a great capacity of the ewes to excrete SCN- and 5-VOT by the milk. A 5-VOT accumulation was observed in the thyroid according to the level of progoitrin in the diet, but no SCN- accumulation. The 5-VOT concentration in thyroid of the ewes fed during three weeks with hay came back to zero. The thyroid analysis showed the reversible aspect of the thyroid hypertrophy due to 5-VOT accumulation. [less ▲]

The impact of 5-VOT on thyroid was studied in two lambs. They received ad libitum water, hay and concentrates without rapeseed from ten days of age till weaning (65 days of age). At 85 days of age, one of them was fed with the same diet but mixed with 100g/d of a rapeseed containing high level of progoitrin: 71.4µmol/g DM (variety Jet Neuf). Blood samples were taken fortnightly for the determination of TSH (Thyroid Stimulating Hormone), T3 (Tri-iodothyronin) and T4 (thyroxin) plasma concentrations. [less ▲]
