[Effects of sugar cane molasses on the nutritive value of Canavalia ensiformis seeds for broiler chicks].
Three experiments were conducted to determine the efficacy of sugar cane molasses to improve performance of broiler chicks fed a diet containing 30% raw or autoclaved Canavalia ensiformis seeds (Jack beans). For this latter purpose, canavalia seeds were ground and autoclaved at 120 degrees C and 15 psi during 60 min. Day-old male chicks (Cobb x Cobb) were used throughout the study. In Experiment 1, adding 10% molasses to a control diet devoided of jack beans seeds significantly (p < 0.05) increased chick feed intake. However, neither the addition of 10% molasses nor of 5% glucose, sucrose, fructose, xylose or corn starch to the 30% raw canavalia ration allowed feed intakes similar to that shown by the control diet (Experiment 2). Broiler performance was evaluated in Experiment 3 in response to diets containing 30% raw or autoclaved jack bean meal. Ten-percent molasses was also added to both diets which along with the control diet were fed to chiks had free access to diets. Growth was depressed when the Jack bean containing diets were pair-fed to chicks. The results indicated that the use of molasses does not overcome the deleterious effects on chick performance due to the presence of 30% raw or autoclaved jack bean meal in the diets.
