Twelve WAD sheep aged 1-2 years old and weighting 14.00± 0.45 kg were used in a complete randomized design. Diets were formulated such that cassava peels was replaced with Gmelina arborea leaf meal at 0, 33.33, 66.67, 100% levels, designated as diets A, B, C, and D respectively. Diet without Gmelina arborea leaf meal was tagged the control diet. The concentrate feed was compounded to contain 16% CP. Diets with 33.33%

Abstract:

The study was carried out to compare the performance of wood hive types and plywood hive types in three different vegetation types between June 2018 and May 2020 in Akure South local Government of Ondo State, Nigeria. A total of eighteen (18) Kenyan Top Bar hives made from Danta, Gmelina and plywood were constructed at six (6) each per wood types. Two (2) each of Danta, Gmelina and Plywood hives were installed in three locations: Natural Forest, Plantation forest and cocoa farmland. The rate of colonization of each hive was evaluated at 6, 12, 18 and 24 months after installation in the field.

The focus was on gmelinol, paulownin, 7′-O-ethyl arboreol, and β-sitosterol, which were isolated and purified from hW. The four compounds revealed a characteristic distribution pattern corresponding to their key role in biosynthesis and depending on their susceptibility to secondary reactions in the

The success of any wood treatment process and the measure of protection conferred on treated wood are determined by the uptake and penetration of the treatment chemicals, in addition to the efficacy of the chemicals used for the treatment. Hence, the level of treatability of wood species should be pre-determined prior to the wood treatment to ensure the overall protection of the treated wood. Gmelina arborea wood, due to its low durability, requires impregnation with chemicals for preservation or chemical modification to enhance its durability.
