The buffer zones of Nigerian protected areas are poorly managed. Patas monkey (Erythrocebus patas) was studied in fact owing to its dearth of information on its ecology and existence in South-West Nigeria National Park. Therefore, it was necessary to examine E. patas spatial distribution and population structure in the Old Oyo National Park buffer zone ranges, situated in South-West Nigeria and as well know its dietary uptake alongside delineating its various activities. Observations were positioned on direct census methods. A total of 60 individuals of E. patas (23 female, 21 male, and 16 young individuals) were sighted within the study period (March to July). The results showed that the highest number of sighted E. patas (18 individuals) was recorded in the month of March while the Marguba range had the highest percentage of sighted E. patas (31.7%). Thirteen plant species were identified as food matters of E. patas while the major activity observed by the majority of E. patas was found feeding on the identified food matters. The food matters consumed were plant parts which included the leaves, flowers, gum, enflamed spikes, and fruits. Actions to uphold and guard the remaining populace of E. patas in the Park and buffer zones should be adequately fortified.

Cassava, a tropical root crop, provides the staple food for millions of people around the world. It is one of the tuber crops that could be cultivated on a small scale in an environment with erratic rainfall, and without necessarily needing heavy equipment and machineries. Cassava could be successfully cultivated by resource-poor farm family. Farmers’ productivity could be as much as 70 tonnes per hectares under favourable conditions. However, smallholder farmers do among other things improve productivity through proven cultural practices and a mix of organic and inorganic measures. Irrigation is very necessary for achieving bumper harvest in areas with shortage of rainfall and insufficient soil moisture content. The concept of sustainability in the practice of agriculture has been on the front burner world over in recent time. Therefore, the cultivation of cassava with the aim of increased productivity without jeopardising the factors of production meant for future time is encouraged. Practices that combine traditional knowledge with modern technologies that are adapted to the needs of small-scale farmers are on the increase around the world. Depending on the purpose, cassava could be harvested anytime from eight month. Cassava leaves could serve as vegetable and the stems use as fire wood.

The quest for enhancing the commercialization and popularity of guinea fowl and ensuring better exploitation of the higher nutritional value it has over other poultry species has necessitated the search for feed additives that will enhance its egg laying potential. A 70 days study was carried out to investigate the laying response and egg quality attributes of guinea fowl fed diets containing vitamin E (Vit. E), Selenium (Sel.) yeast supplemented with or without L-arginine (L-arg). A total of two hundred and forty (240), twenty weeks old (average weight of 2,11+ 0,02kg), helmeted guinea fowls were allotted into 8 dietary treatment. Each treatment was replicated thrice with 10 birds each in a completely randomized design. Dietary treatments were arranged in a 4 x 2 factorial arrangement of 4 additives (no additive, Sel. yeast (0,3 mg/kg), Vit. E (30 IU/kg), Sel. yeast + Vit. E) supplemented with or without 1g/kg L-arg. Data generated on laying performance and egg quality attributes of the birds were subjected to analysis of variance (ANOVA) using the general linear model of statistical analysis system. Supplementation of diet with L-arg improved (P<0,05) the number of eggs collected per day (19,73 eggs) and hen day production (65,76 %) compared with diet without L-arg supplementation (17,68 eggs, 58,90 %). Birds fed diet supplemented with Vit. E + Sel yeast had the highest (P<0,05) number of eggs collected per day (19,40 eggs) compared with those fed other diets (P<0,05). Also, Birds fed with various additives had higher (P<0,05) hen day production (63,33 %) when compared with those fed the control diet. Birds fed diet containing Vit. E + Sel yeast supplemented with L-arg had the highest (P<0,05) total number of eggs collected per day (21,00 eggs) and hen day production (70 %). Supplementation of diet with various additives had significant effect (P<0,05) on yolk weight (8,06-12,53 g), yolk height (10,49-16,73 mm), yolk percentage (24,62-35,17 %) and albumen weight (14,04-17,06 g). Supplementation of Guinea fowl diet with various additives led to an increase in the number of eggs produced per day. It was concluded that inclusion of Vit. E and Sel yeast supplemented with L-arg enhanced laying performance and egg quality attributes of guinea fowls. Further studies should be conducted using other poultry species such as turkey, quail and broilers.
