  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.

  The aim of the study was to assess the effect of soymilk on spermatozoa and its use as an extender. Twelve Yankasa rams between 12-48 months old were used for the study. The semen was collected with an electroejaculator, evaluated for sperm concentration and percent sperm motility, live spermatozoa and sperm abnormalities. The best semen samples were randomly assigned to four extenders (Cornell University Extender, CUE), whole milk glycerol extender, soymilk glycerol extender and soymilk-CUE). These samples were stored for 4 days at 5°C and analyzed for semen quality. The result shows the differences between the extenders were not significant for the initial and final percent sperm motility, except for soymilk. There were no significant differences in the extenders for initial and final percent live-spermatozoa except in the spermatozoa extended in soymilk extenders. Out of the four extenders tested for semen preservation in this study, soymilk extender and soymilk-CUE least supported sperm motility and liveability, although soymilk-CUE was better than soymilk. The problem of the poor performance of the soymilk and soymilk-CUE could be due to the concentration of soybean fluid content and/or the antinutritional factors probably present in the soymilk due to the mode of preparation. Further studies are suggested along these lines.

  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.
