چکیده

A framework for the integration of poultry and fish production in the tropics and sub-tropics is proposed. Poultry may be integrated with fish culture in several ways and benefits extend to both. Both poultry production and processing wastes have value as nutrient inputs to fish and the water used for fish culture can be used for evaporative cooling of poultry and fertilization of crops. The conceptual basis of controlled eutrophication of fishponds using poultry manure for the production of herbivorous fish is compared to feeding of abattoir wastes to carnivorous fish. A comparison of poultry production systems in terms of their potential for integration with fish culture is made; the modern feedlot is compared and contrasted with traditional systems. The nature of poultry wastes is reviewed with respect to the effect of poultry strain/species, diet, and poultry and waste management. The impacts of the use of bedding materials, frequency of waste collection and contaminants are discussed. The use of poultry feedlot waste alone for fish culture is compared to the use of waste and additional fertilisers or feeds. The relative value of wastes from scavenging poultry alone or together with other inputs is analysed. The political economy of current poultry and fish production are considered in this article. The impacts on public health and the environment are also discussed.

Integrated crop-livestock farming systems

a substantial global increase in the demand for food of animal origin, while also aggravating the competition between crops and livestock (increasing cropping areas and reducing rangelands). The livestock revolution 1 is stretching the capacity of existing production, but it is also exacerbating environmental problems. Therefore, while it is necessary to satisfy consumer demand, improve nutriti...

5 Crop–Livestock Systems in Sub-Saharan Africa: Determinants and Intensification Pathways

Mixed farming systems involving varying degrees of crop–livestock integration are found in many parts of Sub-Saharan Africa. Increasing population combined with climatic, economic, social, and institutional changes are transforming systems for producing crops and livestock—from systems based on extensive, shifting cultivation and grazing to ones that are more intensively managed and are based o...

Nutritional constraints to grazing ruminants in the millet-cowpea-livestock farming system of the Sahel

Growing pearl millet and cowpea in combination with raising ruminant livestock is widely practised in the Sahel. In this farming system, livestock feeding depends mostly on rangeland, fallows and cropland grazing. Nutritional constraints to grazing ruminants stem primarily from feed scarcity and seasonal fluctuations in feed supply associated with low rainfall and poor soil fertility. Low feed ...

Strategies for improving water use efficiency of livestock production in rain-fed systems.

Livestock production is a major consumer of fresh water, and the influence of livestock production on global fresh water resources is increasing because of the growing demand for livestock products. Increasing water use efficiency of livestock production, therefore, can contribute to the overall water use efficiency of agriculture. Previous studies have reported significant variation in livesto...
