| Popis: | Seven groups of 10 growing rats each were fed a control diet or rapeseed diets with glucosinolate contents ranging from 4.4 to 36.6 mM/kg DM. After a 5-day adaptation period, the rats were fed ad libitum for 17 days. The food intake of the experimental groups was maximal after 11 days and was, on an average, 4 to 45% lower than that of the control group. The differences were still greater during the last 7 days. Daily weight gain was also maximal after 8 days and began to decrease, dropping to 1 g during the last days. There were negative curvilinear relationships between food intake or weight gain and diet glucosinolate content. Liver weight (g/100 g of body weight) was not significantly altered by glucosinolate intakes between 0.08 and 0.39 mM/day. However, in the groups fed the diets with the lowest glucosinolate contents, plasma triiodothyronine (T3) and thyroxine (T4) levels were 50% lower than in the control group and 70 or 80% lower, respectively, with the diets having the highest glucosinolate contents. |
