Utilização do restolho de sorgo como forragem seca para ruminantes, Etiópia

O restolho dos cereais são amplamente utilizados para a alimentação de ruminantes e, nas regiões semiáridas, o restolho de sorgo pode constituir uma parte importante da dieta do gado durante a estação seca, ajudando a manter a condição e aumentar a sobrevivência. Foram melhoradas variedades de sorgo resistentes ao ataque dos pássaros, para uso em zonas semiáridas e para aumentar a produtividade do grão nas áreas mais afetadas pelas aves. No entanto, as mesmas propriedades que conferem resistência às aves atuam como fatores anti-nutricionais para os ruminantes e, portanto, podem diminuir o valor do restolho de sorgo como espécie forrageira. Estratégias que impliquem a alimentação de restolho em excesso permitem que os animais selecionem preferencialmente o material foliar em vez do caule, que tem maiores concentrações de fatores anti-nutricionais.

Hay Box Brooder: A Milestone to Increase Rural Households Poultry Production

Using the hay-box chick brooder is a simple technique which conserves the metabolic heat produced by the chicks and thus keeping them warm. Unlike other brooders, this device does not require coal, oil, or electricity for heating.

The following description gives detailed information on how to build and manage the hay-box, in addition to tips on how to preserve the Box and the chicks during the different seasons and how to maintain the required temperature based on experiences in Ethiopia.

The hay-box chick brooder which is not using any artificial heat is an ESTC (Ethiopian Science and Technology Commission) award winning technology developed by Prof. Solomon Demeke at Jimma University College of Agriculture and Veterinary Medicine (JUCAVM) (Solomon, 2003).

Élevage des chèvres laitières

Dans toute l’Afrique orientale, on observe une pression croissante sur les terres. La taille moyenne des exploitations diminue à mesure que les parcelles se morcellent et que les paysans se débattent pour trouver de l’espace tant pour produire des cultures de subsistance et de rente que pour élever du bétail. La plupart des paysans souhaiteraient élever des vaches laitières mais ils ne possèdent pas assez d’argent pour se procurer les animaux, construire des étables pour la stabulation permanente ou assez de terre pour produire le fourrage nécessaire. Mais avez-vous déjà songé à élever des chèvres laitières en considérant qu’il s’agissait là d’une option abordable et avantageuse ?

Lutter contre les parasites du mouton

Les moutons qui broutent dans les pâturages peuvent être infestés par plusieurs types de parasites. Le niveau d’infestation parasitaire doit faire l’objet d’un contrôle. Dans le cas contraire, l’infestation peut entraîner des saignements,
l’amaigrissement et même la mort de l’animal. En cas d’hydatidose (maladie due à l’infestation par un ténia), le cycle biologique devra être surveillé pour éviter que ne surgisse un problème de santé publique entraînant la mort des personnes infectées. Ce dépliant explique comment lutter contre les parasites du mouton.

Improved grazing land

Improved grazing land management is vital to increase food security and alleviate poverty, as well as to bring environmental rewards. To address these problems,
the national Soil and Water Conservation (SWC) rogramme in Ethiopia initiated a grazing land management project in the year 2000. Implementation of the technology includes the initial delineating of the grazing land, and then fencing to exclude open access.
This is followed by land preparation, application of compost (and, if necessary, inorganic fertilizers) to improve soil fertility, then planting of improved local and exotic fodder species, grass as well as legumes. Maintenance activities such as weeding, manuring and replanting ensure proper establishment and persistence. Fodder is cut and carried to stall-fed livestock. Once a year, grass is cut for hay, which is stored to feed animals during the dry season. The overall purpose of the intervention is to improve the productivity of grazing land and control land degradation through the introduction of productive techniques and improved fodder species, which consequently improve livestock production. Commercialization of animals and marketing of their products increases the income of farmers.

Mise en place d'une pépinière d'arbres

En Afrique orientale, beaucoup des gens dépendent des forets et des arbres pour satisfaire divers besoins. Avec des populations croissantes, ces ressources sont en train de s'épuiser. De nombreux paysans souhaiteraient planter des arbres, mais il leur est difficile d’obtenir des plantules de haute qualité. La mise en place d’une pépinière d’arbres peut aider à résoudre le problème lié à cette demande et servir aussi de source de revenus supplémentaires.

Worm control in sheep

Every sheep grazing on pasture is infested with one type of worm or the other. Failure to control clinical worm infestation in sheep can result in blood loss, thin animals and death. In case of hydatid disease (a disease related to infestation with tapeworm), failure to control the life cycle can result in a public health problem and deaths in infected humans.

Rearing Dairy Goats

Throughout Eastern Africa pressure on land is increasing. Average farm size is decreasing as plots are sub-divided and farmers struggle to find space on their farms to grow subsistence and cash crops as well as keep livestock. Many farmers would like to keep dairy cows but do not have the money to buy animals and build zero-grazing units or sufficient land to grow enough feed. But have you ever considered keeping dairy goats as a more affordable and appropriate option?

Processing Tomatoes

Tomatoes are widely grown and used in Eastern Africa. During the peak season most farmers sell their tomatoes at throw-away prices and substantial quantities go to waste because they are highly perishable.
To avoid this, farmers can process tomatoes into various products for storage and use at home or as value-added products for income generation.

Improved practices in rearing indigenous chickens

Indigenous chickens play an important role in the livelihoods of most rural families in Eastern Africa. Despite increased use of commercial breeds by large-scale producers, around three quarters of chickens in the region are indigenous breeds. This manual gives information on improved management practices of rearing indigenous chickens. The following technology is from the Technical Centre for Agricultural and Rural Cooperation (CTA) in collaboration with several African institutes ( Ethiopia, Tanzania, Uganda, Kenya).

Establishing a tree nursery, East Africa

Many people in Eastern Africa depend on forests and trees to meet various needs. With growing populations, these resources are being rapidly depleted. Many farmers want to plant trees but cannot readily obtain high-quality tree seedlings. Establishing a tree nursery can help to meet this demand and provide you with extra income.

Dried meat techniques: Examples from different regions

Drying meat under natural temperatures, humidity and circulation of the air, including direct influence of sun rays, is the oldest method of meat preservation. However, various methods, typical for different regions, exist to produce dried meat with or without additional treatment. The following examples of dried meat techniques are part of FAO's publication: Manual on simple methods of meat preservation, which is mainly intended to disseminate information on traditional methods of meat preservation and addresses aspects of hygienic slaughtering under rural conditions in Africa.

Use of sorghum stover as dry season fodder for ruminants, Ethiopia

Cereal stovers are widely used for feeding ruminant livestock, and in semi-arid areas sorghum stover may be an important part of livestock diets during the dry season, helping to maintain condition and increase survival. Bird-resistant varieties of sorghum have been bred for use in semi-arid zones to increase yields of grain in areas most affected by birds. However, the same properties that confer bird-resistance, act as anti-nutritive factors for ruminant livestock, and may therefore lower the value of sorghum stover as livestock fodder. Strategies involving feeding of excess stover enables animals to preferentially select leaf material rather than stem, which has greater concentrations of anti-nutritive factors.

Tsetse Muse: Helping planners to design cost-effective tsetse control strategies

Tsetse flies occur in 36 countries and a total area of between 9 and 10 million square kilometres in Africa. Throughout this area the disease transmitted by the tsetse fly, Trypanosomiasis (or Trypanosomosis), has a significant effect on large numbers of livestock. About 50 million cattle and tens of millions of small ruminants are considered to be at risk from Trypanosomiasis, and the disease is considered as an obstacle to poverty reduction and food security in Africa. In addition, according to the World Health Organization (WHO), more than 60 million people, mainly living in rural areas of sub-Saharan Africa, are at risk of human African trypanosomiasis, or sleeping sickness. An interactive programme to assess the impact of control operations on tsetse populations in relatively homogenous savanna habitats of Eastern and Southern Africa. Tsetse Muse is designed to help planners choose strategies for controlling tsetse from the range of currently available techniques. The programme allows the user to define the parameters for a tsetse population and then view the impact and cost-effectiveness of different control strategies, including combinations of different techniques.
