Evaluation of effects of supplementation of sun-dried leaves of mucuna poggei on the growth and carcass characteristics of broiler birds

摘要

An eight week evaluation of the effects of supplementation of sun dried leaves of Mucuna poggei on the growth and carcass characteristics of broiler birds was carried out. Forty broiler birds (a day old) were grouped into four (10 birds each). The feed of groups A, B and C were supplemented with 20g, 30g and 40g of sun-dried leaves of Mucuna poggei respectively, while group D served as control. The weights of the broilers were taken three times in a week and their average weekly weights were obtained. At the end of the eighth week, the birds were euthanized and weight of different body parts taken to determine the quality of their meat and the characteristics their carcasses. The breast meats were used for drip and cooking loss determination. Results showed that the feed conversions as well as the growth rate of group B birds were the best, having a highest mean live-weight of 1797.67±7.37g. The group also had the most superior carcass characteristics and a few other qualities studied. This was followed by group A with a mean live-weight of 1700.50±4.20g, followed by group C (1550.67±6.03g) while group D (Control) had the least growth and mean live-weight of 1327.50±3.54g. Statistical analysis revealed significant differences (P<0.05) between group B and others. The implication is that at 30g daily supplementation rate, sun dried leaves of Mucuna poggei could be used to enhance the growth rate and carcass characteristics of birds with no deleterious effects. Also, leaves of Mucuna poggei could be sundried and used during the dry season. However there is need to subject Mucuna poggei leaves to processing methods that can reduce the antinutrients contents for more efficient utilization of its nutrients in broiler birds.
