This review discusses the nutritive value of Leucaena leucocephala and its mimosine toxicity when used as a forage for livestock. Chemical analysis and feeding trial. have indicated that Leucaena leaf-meal with its high protein, calcium, -carotene and xanthophyll contents, is potentially a valuable feed for livestock in the tropics. The symptoms of mimosine toxicity in cattle, sheep, poultry, g...

To characterise the urban livestock keeping practices and constraints in Kisumu municipality, Kenya, a questionnaire survey was carried out. Thirty-four contact farmers were interviewed on general farm characteristics and production constraints. The farming activities were categorised as either livestock only (41%), or mixed crops and livestock (59%). The surveyed farmers kept mainly cattle (10...

John M. Marsh (406) 994-5621 [email protected] Cost efficiencies are an important factor in the red meat industry. These efficiencies refer to technological changes, resource configurations, and management strategies that result in firms reducing per unit costs of output (including risk). Cost efficiencies in livestock and meat marketing are critical for the economic survival of firms that com...

Most livestock and poultry odors are generated by the anaerobic decomposition of livestock wastes such as manure (feces and urine), spilled feed, bedding materials, and wash water. Increased organic loading rates due to expanding animal numbers, slug loading, concentrated waste streams, and/or inadequate amounts of dilution water increase the potential for odor emissions from waste management s...

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...

Namibia hosts the worldwide largest free-ranging cheetah population (Marker-Kraus et al. 1996) with 95% of this population roaming outside of protected areas on commercial farmland (Morsbach 1987, Marker-Kraus & Schumann 1998). Commercial livestock farming and trophy hunting have a large economic importance in Namibia and generate substantial income (Marker-Kraus et al. 1996, Barnes et al. 2001...

The livestock sector globally is highly dynamic. In developing countries, it is evolving in response to rapidly increasing demand for livestock products. In developed countries, demand for livestock products is stagnating, while many production systems are increasing their efficiency and environmental sustainability. Historical changes in the demand for livestock products have been largely driv...
