Abstract

Experiments were performed on 100 lambs, of common race, divided into 4 homogeneous groups of 25 lambs each, which were fed, differentiated for 3 weeks. Lots 1.2 and 3 received a supplement consisting of by-products obtained from the manufacture of biofuels in the area: Feed rations had similar nutritive values for all lambs in the experimental plots. The amount of crude protein in concentrates ratio was 17.40% for group 1, 18.44% for group 2, 17.60% for group 3, and 17.00% for group 4. Bulky feed were given ad libitum for all groups. After the first week of the experiment there was a spectacular evolution of body weight gain. All experimental lots were situated beyond the control group. Body mass growth rate is 3.5 times higher in the group fed with supplement of sunflower meal, 4.16 times higher in that fed with soybean meal supplements and 5.2 times higher in the group fed with additional rape meal. After the second week, the differences are decreasing, as the absolute value of body weight gain.
