Title: Growth performance of grasscutter fed under different feeding regimes Authors: Adewumi, A. A.; Alabi, B. O.; Alabi, O. M. Abstract: Twelve(12) grasscutters of both sexes with an average initial weight of 0.870kg were randomly divided into three treatments of four animals each. T1, T2, T3 were 100% Concentrate, 40% Elephant grass + 30% Sweet cassava+ 30% concentrate; 50%Elephant grass +50% Sweet cassava root respectively. They were fed 100g per head per day of the experimental diets and all the animals were given cool water ad libitum. The experiment lasted for 70 days after a seven day adjustment period. Completely randomized experimental design was used. The final mean weight and total weight gain were both significant(p<0.05). The daily weight gain showed significant(p<0.05) difference. T1(7.86g) had the best even though it was similar to T2(7.11g). Daily feed intake decreased linearly (p<0.05) from T1 (66.64g) to T3 (61.50g). Feed conversion ratio also showed significant (p<0.05) differences. Based on this work, concentrate feed can be fed solely to grasscutter without any adverse effect. However, similar result could be achieved grasscutters are fed with 40% elephant grass + 30% sweet cassava root + 30% concentrates.

Cholesterol- A controversial component of poultry egg

Title: Cholesterol- A controversial component of poultry egg Authors: Alabi, O. M. Abstract: Egg is a very cheap source of animal protein. The presence of cholesterol in it is making some people to be abstaining from its consumption for the fear of arteriosclerosis. This fear is so much despite the fact that the level of animal protein consumption per day in developing countries is still below the expected. Most of the people concerned are ignorant of the endogenous production of cholesterol is much and can be elevated by other sources and habits other than egg consumption. Consumption of fibrous food, low fatty meats and avoidance of smoking and coffee drinks with regular physical exercises are ways of avoiding arteriosclerosis. Egg can therefore be consumed at any age without the fear of having cardiovascular or cerebrovascular diseases among people in developing countries where there is need to increase the daily intake of animal protein.

Sustainable forest management in Nigeria: Lessons and Prospects

Title: Sustainable forest management in Nigeria: Lessons and Prospects Authors: Akande, J. A. Abstract: Extensive survey of forest-reliant firms including sawmills and other large integrated wood processing complexes was carried out. The survey employed physical evaluation of production facilities and completion of structured questionnaire using information collected from respondents at the mill sites. Results showed that the Nigerian forest industry is limited by environmental and energy imperatives. Many of the wood industries were established without adequate attention given to environmental protection. The industry is strongly dependent on contractors who care little about reduced impact logging (RIL) once they can make profit. Forest industry wastes also place significant burden on exploitation regime and environmental protection. The firms generally have no pollution records. Sawdust dumps constitute social nuisance and should be channeled towards production of value added wood products. Many of the no pollution records. Sawdust dumps constitute social nuisance and should be channeled towards production of value added wood products. Many of the firms have no first-aid medical facilities, thus, workforce protection against operational hazard is limited. Half-masking is generally employed against dusts and smoke while other hazard sources like noise, fire, electricity, heavy weight, moving objects, chemicals etc are treated with less concern. Other hazards faced by logging contractors include vehicular breakdown, marshy and un- motorable terrain that limits hauling. Inter-ethnic conflicts often introduce major barriers to timber availability and dynamics. Energy-wise, the operators generally rely on public grid for electricity, which is not reliable, causing frequent interruption of !",;-;:',,-.;ssing. There is about 50% downtime resulting from National Electric Power Authority (NEPA) failures leading to irregular industry work schedule. Finns that employ the use of power generators also find it difficult to cope with rising cost of fuel that is disincentive to sawmill expansion and profitability, hence, a rising trend of mill closure. Burdensome is the effect of corruption and bureaucracy along the wood marketing chain that force actors to look for illegal means of increasing profit margin by way of illegal felling. Over 90% of the mills have no approved Environmental Impact Assessment (ElA) neither do they carry out energy audit (EA). All these have undue effects on industrial efficiency and sustainability of the raw material base.
