Pakistan Journal of Nutrition , 2006,
Abstract: A comparative study was carried out on nutritional and technological qualities of fourteen (14) cultivars of Pennisetum glaucum .The contents of proteins ranged from 8.66 % to 17.11 % for all the cultivars. IKMP3, IKMP5, SOSAT C88 and L Zatiib were reveled to be excellent sources of proteins. Water-soluble proteins ranged from 1.81 % to 3.18 % . Fat content in the grains values ranged from 6.76 % to 10.24 %, the best cultivars for fat were IKMP3, IKMP5, SOSAT C88 and KM. The carbohydrates are the major components of these cultivars, values ranged between 71.82 % to 81.02 % and samples IKMP1, IKMP2, TK, B1, B2 contained more carbohydrates than all others cultivars. The energy values of cutivars flours ranged from 426.21 Kcal/100g to 446.53Kcal/100g. Results of Technological properties showed capacities of swelling in water (VI/VF) ranged from 2.33 and 8.28. Masses of 1000 grains ranged from 5.53 g to 13.13 g; cutivars IKMV8201, IKMP5, B1 had the highest masses of 1000 grains and consequently present better outputs potential millers. Starch is present in relatively significant quantity of 51.49 % at 79.07 % and cultivars IKMP1, B1, and SG have the most raised contents. The crude fibres also are present in high quantity 8.06 % to12.40% and cultivars IKMP3, SOSAT C88 are provided greater quantity. The cultivars contents of phytates from 5.45 to 14.26 mg / g and in polyphenols from 2.27 to 3.20 mg / g. The energy values of cultivars flours lies between 426.51 kcal / 100 g and 446.53 kcal / 100 g. Samples IKMP3, IKMP5, SOSAT C88 and KM are equipped best with it. In addition, cultivars IKMP3, IKMP5, S0SAT C88, IKMV8201, KM and L Zatiib have better nutritional profiles.

Aly Savadogo,Cheik A.T. Ouattara,Imael. H.N. Bassole,Alfred S. Traore
Pakistan Journal of Nutrition , 2004,
Abstract: Eight strains of lactic acid bacteria producing bacteriocin were isolated from Burkina Faso fermented milk samples. These strains were identified to species: Lactobacillus fermentum, Pediococcus spp., Leuconostoc mesenteroides subsp. meseteroides, Lactococcus. Isolated bacteriocin exhibited antibacterial activity against Enterococcus faecalis 103907 CIP, Bacillus cereus 13569 LMG, Staphylococcus aureus ATCC 25293, Escherichia coli 105182 CIP using the agar drop diffusion test. The inhibition diameters obtained with bacteriocin are between 8 mm and 12 mm. Gram-positive indicator bacteria were most inhibited. The activities of the bacteriocin were lost after treatment with all the proteolytic enzymes (alpha-chymotrypsin, trypsin, pesin), whereas treatment with lipase, catalase, alpha-amylase did not affect the activity of the bacteriocin.
Biochemical, Microbial and Processing Study of Dèguè a Fermented Food From Pearl millet dough) from Burkina Faso
Fatoumata Hama,Aly Savadogo,Cheik A.T. Ouattara,Alfred S. Traore
Pakistan Journal of Nutrition , 2009,
Abstract: Dèguè was a traditional fermented food (pearl millet dough) which consumed in Burkina Faso. In this work, the traditional processing of pearl millet into dèguè was investigated in 18 traditional production units. This study was followed in Ouagadougou and Bobo-Dioulasso. The main steps of diagram of production were dehulling, winnowing, washing, drying, milling, sieving, kneading, cooking, pounding, shaping and fermentation. Before fermentation, crude protein, crude fat, ash, starch and carbohydrates content were respectively 5.43; 3.00; 1.13; 33.37 and 41.81 %. After 72 hours of fermentation only protein content (6.12 %) was increased; starch content was(23.6 %) decreased. pH and titratable acidity were respectively 6.75 and 0.12 before the fermentation and after 72 hours pH (4.49) was decreased and titratable acidity (0.57 g of 100 grams of lactic acid) was increased. Microbiology analyses indicated that the number of lactic acid bacteria, yeasts and moulds increased during the course of fermentation. The number of coliforms was decreased slightly after 72 hours of fermentation.
The Preservation and Conservation of Nigerian Cultural Heritage: An Impetus for Her Development
A.T. Ajayi
The Social Sciences , 2013,
Abstract: The preservation of the cultural heritage of a nation has become an impulse towards its development. Most states of the globe have come to realize that cultural heritage is an essential aspect of human life and its promotion and preservation an asset of a state. This study explores the problems inhibiting cultural integration in a developing country like Nigeria with plural and diversified cultures and the need to promote culture that stresses virtue, which is pivot to growth-oriented economy.

The problems with multi-species conservation: do hotspots, ideal reserves and existing reserves coincide?
A.T. Lombard
African Zoology , 2011,
Abstract: South Africa urgently requires a national strategic plan for the conservation of the country's biodiversity. The formulation of such a plan would be relatively easy if centres (hotspots) of richness, endemism and rarity were congruent, both within and among many different taxa, if these hotspots captured a large proportion of the total species, and if hotspots fell within existing reserves. The investigation of six vertebrate taxa (viz freshwater fish, frogs, tortoises and terrapins, snakes, birds, and various mammal orders) at a national scale reveals that hotspots are not coincident within taxa. Centres of richness are concentrated in the north-eastern areas of the country, whereas endemism is concentrated in the south-west, and centres of rare and threatened (Red Data Book) species can be in either area. Paired comparisons among taxa reveal greatly varying proportional overlaps of species richness hotspots (0-72%). The proportion of total species falling in hotspots ranges from low (66% for fish) to high (92% for birds). Hotspots are thus not an efficient method of siting representative (ideal) reserves. In order to design a more representative reserve system to protect all vertebrate species, a complementarity algorithm was applied to all taxa separately, and then to all taxa combined. The combined analysis yielded more efficient results (66 reserves are required to represent all 1 074 species at least once) than the separate analyses (97 reserves). Many of these representative reserves coincide with both hotspots and existing reserves, and over 85% of the hotspots of most taxa coincide with existing reserves, thus South Africa's vertebrate fauna could be more effectively protected with only moderate acquisition of new, well-sited reserves. A biome analysis reveals that these reserves will also have to incorporate areas of those biomes that are currently inadequately protected, viz grassland, Succulent Karoo and Nama-Karoo. The methods outlined in this paper should be applied to as many other taxa as possible, in order to aid the formulation of a national strategic plan for biodiversity conservation.

Introduction to an evaluation of the protection status of South Africa's vertebrates
A.T. Lombard
African Zoology , 2011,
Abstract: During the Zoological Society of Southern Africa's 1994 Symposium in Pietermaritzburg, a theme session was convened to evaluate the protection status of selected groups of South African vertebrates (viz. freshwater fish, frogs, tortoises and terrapins, snakes, birds, and various mammal orders). The research papers presented during that session are reported in this number of the South African Journal of Zoology. The rationale behind the research, and the data and methods used, are described in this introductory paper. South Africa's national and international contractual obligations to conserve its biodiversity, and the urgent need for a national conservation strategy and national conservation information networks and databases, are also discussed.
Evolving perspectives on caribou population dynamics, have we got it right yet?
A.T. Bergerud
Rangifer , 1996,
Abstract: The roles of food, weather and predation are compared between sedentary and migratory caribou herds. Sedentary herds disperse (space out) at calving time while the cows of migratory herds move in masse (space away) to calving grounds to reduce predation risk. The sedentary ecotype calves on ranges near open water if tree cover is present or in rugged topography in the absence of tree cover. The migratory ecotype aggregates on calving grounds located on alpine mountain plateaus or on the tundra north of the Arctic tree line. The two herds with the greatest densities in North America, the sedentary Slate Islands Herd and the migratory George River Herd both had changes in abundance that followed summer food problems. The hypothesis that winter lichen supplies determine abundance and set the carrying capacity is rejected. Lichens are not a necessary food for caribou. A review of the mortality of young calves documented in the past 30 years provides no support for the hypothesis that hypothermia is a common mortality problem. Young calves documented can be born inviable at birth if their dams are severely malnourished. The migratory caribou in North America reached peak numbers in the 1980s after wolf populations were heavily harvested in the 1970s. The sedentary ecotype is frequently regulated by wolf predation that affects both recruitment (R) and the mortality of adults (M). The balance between R/M schedules commonly occurs when R (calves) represents, about 15% of the herd and when numbers (prorated to the area of the dispersed annual range) approximate 0.06 caribou/km2. Population limitation of migratory herds by predation has occurred in the NWT and in several herds in Alaska but only when wolf densities were > 6.5/1000 km2. Wolf predation halted the growth of the George River Herd in 1980 but then wolves contracted rabies and the herd again increased and degraded spring/summer ranges. The reduced summer phytomass resulted in lower birth rates and increased the vulnerability of calves and possibly adults to wolf predation. Stabilizing mechanisms for migratory herds include movements between herds above tree line and range contractions/expansions with resultant changes in demography. It is hypothesized that the most important ecological variable in all seasonal distributions of caribou is predation risk rather than to maximize forage supplies.
