Global drivers such as the growing human population, evolving consumer preferences, globalization, and climate change have put pressure on agri-food sector to produce more livestock products with less land, feed, water. Taste, nutritional value, cost, convenience, source, animal welfare, environmental sustainability of food are criteria upon which purchasing decisions made. In response, an foot...
Livestock projects were established to improve household food security and the nutritional status of household members by increasing the consumption of dairy products. Dairy farming dominates the livestock contribution to household economies and is one of the highest deliverer of the per capita milk availability in sub-Saharan Africa. Effort was been made to identify factors that associated wit...
This paper tests predictions derived from the non-equilibrium theory of rangeland science. Data were collected in livestock enclosures situated in the relatively moist desert steppes of the Gobi Gurvan Saykhan region of southern Mongolia from 2000 to 2003. Plant community composition and species’ richness in enclosures showed clear differences between years, but these were equally strong in ung...
The African buffalo (Syncerus caffer) is a large wild bovid which until recently ranged across all but the driest parts of sub-Saharan Africa, and their local range being limited to about 20 km from surface water. They are of high ecological value due to their important role as bulk feeders in the grazing hierarchy. They also have high economic value, because they are one of the sought after...
This paper describes the institutional background against which invasiveness is considered with regard to livestock genetic diversity. The human-made nature and extensive spread of a few domesticated animal species for global food production is a feature of agricultural diversity that complicates the simple, negative view of invasive species. The different impacts of livestock species on natura...

The rendering industry collects and safely processes approximately 25 million t of animal byproducts each year in the United States. Rendering plants process a variety of raw materials from food animal production, principally offal from slaughterhouses, but include whole animals that die on farms or in transit and other materials such as bone, feathers, and blood. By recycling these byproducts ...
Livestock, particularly small stock plays an important role to small-scale resource poor livestock keepers. Their efficient utilization on small land holdings result in enhanced farm family nutrition and increased farm productivity, hence focus on their development can be one way of reducing poverty among the poor. Past goat genetic improvement programmes in Kenya were based on government resea...
Eco-efficiency is concerned with the efficient and sustainable use of resources in farm production and land management. It can be increased either by altering the management of individual crop and livestock enterprises or by altering the land-use system. This paper concentrates on the effects of crop sequence and rotation on soil fertility and nutrient use efficiency. The potential importance o...
