  Ackee Apple Seeds (AAS) subjected to chemical detoxification with glycine and riboflavin at 5% coupled with traditional treatments of soaking and boiling to leach out some soluble AAS toxins, hypoglycin A and B, was evaluated for nutritional adequacy using day chicks (DOC). Six iso-caloric and nitrogenous diets were prepared with graded levels of 2.5, 5.0, 7.5, 10.0 and 12.5% AAS meal in rations 2, 3, 4, 5 and 6 respectively. The diets including a corn-soybeans control diet were fed ad libitum to 144-DOC in a 4-week feeding trial. Results showed that the test feedstuff improved blood composition (PCV, WBC). The non- significant difference recorded on lengths of GIT parts including ileum and duodenum relative to the reference diet suggest the similarity of the test diets with the conventional diet (p>0.05). Differences observed on absolute and relative organ weights (AOW and ROW) supported the result on performance which gave significant increase in body weight gain (p<0.05). Results on hematology, GIT, AOW and ROW following detoxified AAS meal ingestion suggest that the methods offer great potential for effective detoxification of Ackee apple seeds.

  An experiment was conducted to investigate the utilization of Jatropha seed cake by Albino rats. Jatropha Seed Cake (JSC) treated by boiling, fermentation followed by extraction with equal volumes of hexane and ethanol was included in diets at graded levels of 5, 10, 15, 20 and 25%. Data obtained on performance and body organ indices showed that rats tolerated up to 15% dietary JSC without adverse effects on the measured parameters in relation to the corn-soy reference diet (p>0.05). However, 20 and 25% inclusion levels elicited mortality in all the animal subjects receiving the diets within one week in the course of the experimental trial.

  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.
