Forty rabbit does were distributed in a completely randomized experimental design, with four treatments (oil-free ration and rations with 3% canola oil, 3% corn oil or 3% soybean oil) and 10 replications. Blood samples were collected on the 16th day of their first and second pregnancies, and on the 11th day after the first birth. Concentrations of total triglyceride, total cholesterol, high (HDL), low (LDL) and very low (VLDL) density lipoprotein (HDL), progesterone and 17ß-estradiol were analyzed in serum. No difference was reported among treatments (p>0.05). However, levels of HDL-cholesterol and 17ß-estradiol were higher in the second pregnancy (p<0.05). Progesterone concentration was lower (p<0.05) during the first pregnancy and became higher 11 days after the first birth. It may be suggested that rations with 3% vegetable oil failed to cause any changes in serum lipid profiles and in steroid hormone levels.
