Abstract: A study on the evaluation of the effectiveness of three traditional methods of protecting guinea fowl from mortality was carried out at CRA-SS (Centre de Recherche Agronomique de la Savane Sèche) in northern Togo. Guinea fowl were divided into 5 batches, of which 3 batches received prophylactic medical treatment including plant decoctions, the 4th batch was followed by a medical prophylaxis program as a control group and the 5th batch considered as a negative control, has not received any prophylactic treatment. The results showed that a mortality rate of 25% for the reference lot and two other batches which received plant decoctions (Euphorbia poissonii or Khaya senegalensis) were recorded against a rate of 87.5% in the batch of guinea fowl which received the decoction of Pteleopsis suberosa. Meanwhile, regardless of weight growth, daily average gain (GMQ) or food consumption, no significant difference was observed (p > 0.05) between the guinea fowl that received a baseline health monitoring and those having taken the decoction of E. poissonii. On the other hand, the values recorded in these two batches of guinea fowl differed statistically from those in the guinea fowl that received the decoction of K. senegalensis. Although the decoction of K. senegalensis has a protective effect in guinea fowl, the growth of guinea fowl has been slowed down. On the basis of these results, it appears that two endogenous practices tested (K. senegalensis or E. poissonii) have positive effects. However, it would be desirable to carry out a toxicity test in order to determine the recommended doses. Key words: Guinea fowl, protection, traditional methods, mortality, Savannah regions, Togo. 1. Introduction about 88% of the farmers use the traditional practices in the control of animal diseases [13]. For a long time, In the Savannah region, the breeding of the guinea poultry farmers have known different diseases of fowl has considerable potential for expansion in view poultry, and they develop expertise in the prevention of of the large number of rural households that practice it these diseases, based on the traditional pharmacopoeia, and the strong demand of the guinea fowl market [1-7]. in particular phytotherapy.

This preliminary report covers a total of nine local government areas in the state. The work involved intensive survey and visits to the sample sites for this exercise. The diversity status of each plant and the distribution across the state were also determined using standard method. A total of number of 244 plant species belonging to 57 plant families were identified out of which the families, Asteraceae, Poaceae, Combretaceae, Euphorbiaceae, Moraceae and Papilionaceae were the most highly distributed across the entire study area. There was great extent of diversity in the distribution of plants across all the areas sampled with the highest in Wamba LGA. The most predominant food crop across the state was Sorgum spp. followed by Sesame indica and then Zea mays.

Natural resource, particularly the plants and animals have been the basis of traditional treatment since the dawn of human civilization and the modern medicine (Allopathy) has gradually developed, over the years, by scientific and observational efforts from traditional practice. However, with the advent of antibiotics the role of traditional medicaments in infectious diseases was sidelined. Interestingly after the 1980’s, society realized the problem of drug resistance, emerging and reemerging pathogens, adverse drug reactions of many antimicrobials, particularly the antivirals. Hence, the lag phase for plant medicine is changing as impressive successes have been achieved with many botanicals like artemisinin, baccosides, curcumine, phyllanthins, quinghaosu, rauwolfia alkaloids, psoralens, picrosides, withanolides, steroidal lactones etc against many chronic and difficult-to-treat diseases. A whole range of chronic and lifestyle related diseases including HIV/AIDS, SARS, and Herpesvirus infection require new effective drugs.

Six naturally occurring diterpene esters were isolated from the latex and a further eight were semi-synthesised by selective esterification of the C 2 0 primary alcohol of these resiniferonol and 12- deoxyphorbol nuclei. These compounds were characterised by their ^-NM R, mass spectral, UV and IR properties. Computer-assisted molecular modelling of these compounds in conjunction with standard phorbol ester probes enabled the assessment of their minimum free energy values; resiniferonol derivatives were found to have much lower minimum free energy levels than corresponding 12-deoxyphorbol derivatives.
