Plant Tannins- Their Role in Forage Legume Quality

Forage legumes, especially browse plants, are important in the maintenance and survival of ruminant animals. However many browse species contain high levels of polyphenolic compounds including tannins. The effects of tannins on the quality of forages are reviewed. These include reduction in palatability and intake of feeds, growth rate, digestion of fibre fractions and nitrogen utilization by animals

Performance and Meat Quality of Growing Pigs Fed Composite Leaf Meal Premix as an Alternative to Commercial Premix

This trial was designed to study the effects of using composite leaf meal produced from five (5) different leaves: Cassava, Moringa, fluted pumpkin, African basil and bitter leaves as a premix in the diets of growing pigs. Twenty four large white weaner-pigs were used for this trial comprising six treatments and four replicates with one pig per replicate. Six diets were formulated in which composite leaf meal was fed at 0 (2.5% premix), 10 (2.0% premix), 20 (1.5% premix), 30 (1.0% premix), 40 (0.5% premix) and 50 (0.0% premix) g/kg at the expense of a commercial premix and designated diets I, II, III, IV, V and VI. The pigs were then assigned to these 6 dietary treatments which were fed to the pigs at 5% of their body weight for 8 weeks experimental period. Water was supplied ad libitum throughout the experimental period. All data were subjected to analysis of variance. Results showed that, there was no significant difference (P>0.05) in the final weights of the pigs. Highest final live weight (41.67 ± 0.84 kg) and highest feed intake (75.92 ± 0.06) were recorded in animals fed diet II, while the lowest final live weight (37.67 ± 0.84kg) and lowest feed intake (75.57 ± 0.06) were recorded in animals fed diets V and I, respectively. The eye muscle width of carcass was significantly higher (
