  Background and Objective: The world population is estimated to be more than 9 billion by the year 2050 and this will lead to increased demands for animal protein. Hence, there is need to explore other protein food resources such as insects. This study therefore was conducted to determine the nutrient value of the African palm grub (Rhynchophorus phoenicis) in Bayelsa state, Nigeria. Materials and Methods: Palm grubs were collected from Osika bush (OSB), Yenegue bush (YEB) and Obuolo bush (OBB) in the state and thereafter taken to the laboratory for analysis using standard methods. They were analyzed for linear body measurements and nutrient compositions using descriptive statistics. Results: Results of the proximate compositions indicate that palm grub is a rich source of nutrients. Mean magnesium, calcium, sodium and potassium content across locations differed significantly (p<0.05). Additionally, there was significant differences (p<0.05) in zinc and manganese concentrations across the three locations. The palm grub oil was found to be 100% unsaturated, which makes it to remain in its liquid phase at room temperature due to the presence of unsaturated fatty acids, oleic and linoleic acids. Conclusion: The high nutrient content of palm grub is a pointer that palm grub may be employed in ameliorating the problem of protein and micro nutrient deficiency in both humans and animals.

  Background and Objective: Pigs generates a large number of dungs that could be detrimental to the environment if not properly managed. This study attempt to determine the proximate and mineral compositions in freshly voided pig dung collected from smallholder farms in Imo state, Nigeria for possible use as animal feed. Materials and Methods: Early morning dung were collected from six farms, two from each of the three agro-ecological zones of the state and sundried. The samples were analyzed for their proximate and mineral concentration. Results: The result revealed that pig dungs are good source of dry matter (87.97%), fibre (23.33%), total ash (23.24%) and mineral (potassium, iron, phosphorus). Conclusion: This study revealed that pig dung is a good source of nutrients and could be used as animal feed. The use of pig dungs in animal feed and fertilizer for agricultural soil will lead the development of sustainable environmentally friendly animal and crop farming systems.

  Research on the concentrations of aerial pollutant gases in tropical livestock buildings is needed in order to establish baselines for exposure limits in context of animal and human welfare in the tropical environments. The concentrations of aerial ammonia, nitrous oxide, methane, carbon monoxide, hydrogen sulfide and sulfur dioxide in selected pig pens in the Owerri area of Imo State, Nigeria were measured during the month of August 2002. These were thereafter correlated with pig building measurements in order to determine the possible influence of building measurements on concentration of the gases. Overall mean aerial concentrations of carbon monoxide CO (2.7±0.34 ppm) was the highest mean value recorded and was followed by the 1.4±0.0 and 0.07±0.14 ppm recorded for flammable gas (methane) and hydrogen sulfide, respectively while the 0.0±0.0 ppm recorded for ammonia was lowest. The average length of the buildings was 64.20, while 21.40, 11.60 and 4.35 ft. were obtained for width, height and sidewalls, respectively. In all pens, the simple linear regression was not significant (p<0.05), with the coefficient of determination ranging from 0.001 (SO2) to 0.364 (CO). For the different aerial pollutant gases, the best linear predictor was for CO using height of building followed by SO2 using height and so on based on the R2 values. Even though this study returned low levels of gases for the area during the month of August, there is the need to extend the study to other periods of the year especially the dry season months in other to further elucidate the effects of inclement whether on gas concentrations in pig pens.
