In the region where Banana tree Bacterial Wilt Disease has decimated banana tree plantations after many years, peasants who have only this culture as source of income co-op do not know what to do in order to cope with this continuing plague which lasts for more than a decade. Nevertheless with more or less resistant varieties including the FHIA-25 in the introduction, hope is allowed. However, in the process of planting plantations, regardless of fertilization and which our study has focused on the organic and mineral amendment, nothing can open on an issue to restore the banana fields around the huts in the agglomerated villages. Therefore, soil enrichment based on Tithonia, cow manure and ash is a way out among alternatives allowing farmers to resume the restoration of their banana plantation’s heritage. The results are promising in an endemic zone of banana wilt, sign of devastation, the respect of settlement with organic manure coupled with a versatile fertilizer produced with Tithonia and wooden ash, banana growing rapidly and the vigor of the plants presents an identical aspect to that under the natural conditions, with more performance on soils recognized as being too poor.

Over 50 years, some local NGOs and partners fight against malnutrition as a whole in the region and other support vitamin deficiencies (A) without tackled the problem upstream. Food insecurity, far from being fought from the causes and curb, moved with acuity despite the potential available to households involved in the production of tomato. The answer to food insecurity would increase by a tomato crop, which requires just the minimum phytotechnic appropriate care in the conduct for growth and maintains the production that previously did not respond to the overcrowding due to leakage demographics. In precarious conditions and substantive in nature, the production of tomato knows several constraints and cause it does not grow, in order of importance note that we found that 64, 8% of our small producers reach not 20 meters of usable area, but also the land imbalance over 90% do this activity with the same period of the year by purchasing more than 90% do this activity with the same period of the year by a discount price to markets and 80% do not use soil management systems (without cultural association, rudimentary techniques, not improved seeds) and not followed in the conduct of Culture (the phytosanitary control, respect to pyrotechnic standards). By the time the needs of the everyday use of qualitative and tomato in households falling in step with its production which pushed to seek opportunities and whose intensification ISFM practices (Integrated Management of Soil Fertility) and integration into the mini-livestock (guinea pigs, rabbits, chickens, pigs ...) seem convincing to go up the balance in the diet.

This research consisted to the assessment of the degree of pollution of the waters of the Kivu lake: case of the basin of Bukavu, being given the different affluents that himself pours there with all ways of garbages.
The objective of this last is to achieve a qualitative survey of the waters of the Kivu lake according to the ecological norms in the determination of the temperature, the pH, the alkalinity or the acidity, of the dissolved oxygen and of the biologic and chemical demand in oxygen on one hand; and on the other hand the comparison of the pollution degree in the different mentions retained: SNCC, BRALIMA, PHARMAKINA, BWINDI, KAZINGO and RUZIZI, the waters of large having served like witnesses.
After analysis of results, he/it cleared himself/itself what follows:
- The temperature of the waters of the Kivu lake is variable next one seasons with an average of 23°C;
- The waters of the lake are alkali and variable according to seasons;
- The dissolved oxygen is variable between 2,92 and 4,84mg/l, what is an admissible value for a better life in the aquatic middle because lower to 5mg/l.
He/it is therefore conclusive that the waters of the coastline of the Kivu lake in the basin of Bukavu are polluted in the decreasing order in sites of the following manner: SNCC, PHARMAKINA, KAZINGO, BRALIMA and BWINDI.

Causes of mortalities observed in caviaculture are badly known even ignored by breeders in Sud-Kivu precisely in Walungu area. Thus, we contemplated to have a study in order to characterize ectoparasitosis in this breeding by emphasizing on their symptoms, the identification cutanous scratching and harvest of crust and hair of guinea-pig submitted on the laboratory analysis, suggesting some recommendation especial hygienic adapted to the small breeders in the peasant area by taking into account a test of heal with palmist oil associated with kerosene. All that in order to manage the risks of infestations which can harmer even human beings, because these sicknesses are wellknown as zoonoses.
Our study was applieds in this center of Walungu area where we have first isolated the sick guinea-pig on which we took away cutanous scratching product and hair on animal met and having symptoms of scabies wiich guinea-pigs constitute the fist pattern. The second lot constitutes the hair harvested on guinea-pigs in the pilot farm, in order to characterize ectoparasites by identifying in laboratory where we have put our emphasis of ectoparasits Sarcoptes scabei and Demodex sp type but as well their frequency which vary according to different farm, ages and sex.
Notice that the breeding system which remains traditional is at the origin of dissemination of these ectopasasits mainly if some hygienic rules are not respected. They are the purchasing in the market or in the farms infested, the donation followed by sudden introduction of guinea-pigs in inhurt breeding without quarantine at fist and lack of heal application of these parasits which attack human being. The sanitary care taken for in a mix of 70% of oil and 30% of kerosene renew heath of beasts.

A retrospective study on the reasons of seizures of organs of animals done at the public slaughterhouse of Blessed has been led on one period of five years since 2007 till 2011.
To shortcoming an analysis of its results we look for results to seizures meats characteristics whose energetic value should have suved the cellular metabolism, it has been noted a number very important of carcasses on which have been achieved of the partial seizures. A total of 3077 cases that corresponded to 2835,75 kg of meat seizure have been observed during the study; cattle covered the biggest proportions. The losses in animal proteins were therefore real.
Being about the spoil types, fifteen motives constituted the reason of seizure of one or the other of the organs on the whole in the species bovine, ovine, caprine and porcine.
The bad bled, the distomatose, the pulmonary emphysema, the cysticercose, the caseification, the abscesses, the adhesions, the dotted liver, the tuberculose, the blow up spleen, the angiocholite, the kidney stones, the hydronephrose, the metastrongylose and the verminous nodules.
Among the four studied species, the bovine was the most interesting for which one noted 2197 cases, either 71,4%, in case of pig, 722 cases (23,46%).
Among the small ruminants, the goat covered 3,37% and sheep only achieved 1,75%.
According spoil frequencies, there are no differences statically.
Considering the category of meats seized, it is useful to signal that most came from the red viscera.
In a general manner, the yearly averages were respectively of 29,4cas and 47,5Kg, numbers that are spectacular enough on time where the needs in meat are increasing.
