  The effect of Omega-3-fatty-acid on performance was carried out in sixteen (16) West African Dwarf does between 12 to 18 months of age with an average weight of 10 kg. Supplementation of Omega-3-fattyacid was varied from 0 mg for control to 500, 1000 and 1500 mg for low, medium and high level (s), respectively. Blood samples were collected on days 14, 28, 42 and 56 after Omega-3-fatty acid administration and were analyzed for haematological/biochemical parameters. Different levels of omega-3 fatty acid supplementation had no significant (p>0.05) effect on weight gain or feed efficiency of West Africa Dwarf goats. However, there was significant difference (p<0.05) in feed intake. West African Dwarf goats on 500 mg level of omega-3 fatty acid supplementation was observed to have relatively (p<0.05)the lowest feed efficiency and lowest daily weight gain. Results indicated no significant difference (p>0.05) between the mean values of serum total protein (50.50±6.45 to 43.25±6.45 g L-1) and that of serum cholesterol (3.08±0.43 to 2.93±0.43 mmol L-1) and a significant difference (p<0.05) between the mean values of serum urea level (4.45±0.73 to 6.38±0.73 mmol L-1). Although, there was no statistical difference between the mean values of serum total protein and serum cholesterol there was a tendency for a decrease at high (1500 mg) level of supplementation. There were no significant difference in their serum-glucose concentration, It was concluded that Omega-3-fatty acid can be used as dietary supplement for West African Dwarf does without posing any kind of stress on the health of the animal thereby increasing essential fatty acid in animal products.

  Seeds of Adansonia digitata, Voandzeia subterranean (L.) Thouars, Bilighia sapida, Entada africana, Leucana leucocephala and Mucuna preta were evaluated for their nutritional quality and possible inclusion in ruminant diet. The seeds were analysed for their proximate composition, fibre fractions, mineral composition, energy value and the anti-nutritional factors. The results revealed that the seeds contained between 10.5 and 41.4% crude protein, 7.5 and 22.5% ether extract, 15.5 and 19.5% crude fibre, 17.0 and 39.0% acid detergent fibre, 41.0 and 84.0% neutral detergent fibre and 4.38 and 5.46 kcal/100 g ME. It was also observed that the sodium content was between 0.10 and 0.30 mg/100 g, 1.9 and 15.5 mg/100 g calcium, 8.95 and 46.10 mg/100 g magnesium while the potassium was between 8.95 and 45.15 mg/100 g and the iron content falls between 0.17 and 0.95 mg/100 g. Some anti-nutritional factors (tannin and saponin) were detected and quantified. In conclusion, all the seed samples are potential good sources of dietary energy, protein and mineral content in livestock diet.

  The effect of preparing kunnu from Tiger nut (A) Millet (B) and sorghum (C) on the proximate composition, mineral content and sensory qualities were evaluated in a completely randomized design model. The results revealed highest fat percentage for Tiger nut based kunnu (Treatment A) and poorest for millet based kunnu (Treatment C). The crude protein content of Tiger nut based kunnu (A) was greatest (p<0.05) compared to other Treatments B and C which are similar. There was similarity in the energy content of all the Treatments. The sensory qualities (flavour, colour, taste, texture, general acceptability) were however, observed to increase significantly (p<0.05) in the Tiger nut based Kunnu (A) compared to other sources (B and C). Furthermore, utilization of Tiger nut in the preparation of kunnu was favoured by market price compared to sorghum and millet. Tiger nut based kunnu cost $0.29 per Kg while millet and sorghum based kunnu cost $0.36 per kg each, making a difference of $0.07 per kg surplus. In conclusion, the results obtained show that preparation of kunnu from Tiger nut was cheaper while more nutritious beverage with a high level of acceptability was obtained.

  The purpose of this study was to investigate the importance of milk consumption in the diet of secondary school students in Ibadan North and Akinyele local government areas of Oyo State, Nigeria. Questionnaire was used to elicit information from the students and simple randomly sampling was used to select forty students each from public secondary schools students of urban and rural areas and also forty students from private secondary school in both rural and urban areas. The sample consisted of equal number of males and females. Frequency distributions and percentages were calculated. Student’s t-test was used to determine whether there is significant difference between milk consumption and developmental indices of students. The findings revealed that respondents’ preference was more to liquid than powdered milk while the purchasing power was also in-like manner. The private secondary school students had the highest daily consumption rate and purchasing power than the public school students. The results further revealed that there were statistical differences in height of students (both sexes) of the rural and urban secondary school students while there was no significant difference in the weight and forearms of private and the public secondary school students in both urban and rural. Milk is important in the diet of secondary school students since they are in their developmental stages of life, therefore the study recommends the introduction of school milk programme sponsored by government. Also, nutritional education should be introduced to academic curriculum of secondary school.

  An assessment of 5% Jatropha curcas seed meal, JSM treated by combined physical and biochemical methods was conducted. About 144 days old Olympiad cockerel chicks were fed the variously treated JSM in 6 dietary treatments and their performance, biochemical and blood composition were evaluated in a month feeding trial. Results on performance showed no significant differences in feed intake and weight gain (p>0.05) with a marginal variation in feed efficiency relative to the reference diet (p<0.05) and a very high mortality rate on the diet containing boiled and roasted JSM followed by fermentation. Some biochemical data analyzed showed no significant differences in all the indices measured except the blood cholesterol level and urea excretion (p<0.05). Also, no significant differences were recorded on the activities of AST and AP except ALT (p<0.05). Data on blood chemistry similarly indicated no significant differences in PCV, RBC, HB and the differentials of WBC counts (p>0.05) apart from the difference observed on WBC count (p<0.05). It could be inferred that treating JSM or its cake by most of the methods adopted could bring about detoxification and will have no adverse effect on the fed livestock. Further researches are being carried out to enable inclusion of Jatropha products/by-products at levels higher than the 5% used in this study.

  The aim of this study was to investigate the phytohormonal potential of eight selected tropical plants. Seeds of Tribulus terrestris, Mucuna pruriens, Myristica fragrans, Glycine maximum, leaves of Hyptis suaveolens, Allium cepa, root of Daucus carota and rhizomes of Dioscorea villosa were evaluated for phytohormonal and metabolite constituents for possible extraction to enhance reproductive performance in livestock. The selected plant parts were analyzed for metabolites such as saponin, alkaloids, flavonoids, oxalates and saponin, as well as plant hormones such as auxin, absussic, cytokinin and gibberellins. The result revealed that flavonoid was significantly low in all the selected plants. Saponin was highly significant (p<0.05) in Tribulus terrestris, Myristica fragrans, Dioscorea villosa and Daucus carota. Phytates was highly significant in Mucuna pruriens, Hyptis suaveolens, Glycine maximum and Allium cepa. Oxalates and alkaloids ranged between slightly low and medium in all the selected plants. Auxin was significantly high in Mucuna pruriens, Myristica fragrans, Allium cepa, Hyptis suaveolens and Glycine maximum, while gibberellins was significantly high in Tribulus terrestris, Dioscorea villosa and Daucus carota. Absussic and cytokinin flunctuate between low and medium in all the selected plants except in Hyptis suaveolens where cytokinin was not significantly different from auxin. In conclusion, selected plants such as Tribulus terrestris, Myristica fragrans, Dioscorea villosa and Daucus carota with high saponin will hypothetically be use to enhance reproductive performance of animals generally. Myristica fragrans might be useful in females due to its high saponin and auxin, while Dioscorea villosa and Daucus carota could be use on males due to its high saponin and gibberellins. Tribulus terrestris, Allium cepa, Hyptis suaveolens and Glycine maximum could be researched for phytohormonal effect on both sexes.
