Buying lighter animals and placing them in pastures before sending them to feedlot is the most profitable as well as least risky option. Even in the least risky scenario, the cattle owner would still incur losses 28% of the times. The results also show a possibility that at contract-grazing rates of $0.41 per pound of gain or more, the cattle owner would place cattle directly on the feedlot, bypassing the pasture.

Production systems were: 1) feedlot (FL), housed in individual pens and fed 40% protein pellets, 40% soybean hulls and 20% bermuda grass hay; 2) grazing continuously on 1 hectare bahia grass pasture (BP) supplemented daily with 150 g of protein pellets/h/day; and 3) browsing rotationally on 4, 0.5 hectare mimosa (MB) supplemented daily with 100 g cracked corn/h/day. Body weights were recorded every two weeks. Feed intake and digestibility were measured on eight goats from each treatment groups. Goats were fitted with canvas fecal collection bags, allowed for 3 days of adjustments followed by 5 days of fecal collection. Feces, feed offered, pasture and browse samples were analyzed for acid insoluble ash to determine digestibility and predict intake. Rumen fluid and blood samples were collected to measure volati...

Petroleum provides the single largest fraction of the world’s energy (40% of total world energy used) and for most countries a large percentage is imported from politically volatile locations (IEA, 2002). Petroleum is also considered one of the largest single contributors to trade deficits in many countries. Burning non-renewable fossil energy sources contributes to carbon dioxide and other greenhouse gas emissions in the atmosphere, raising concerns about global climate change. Non-renewable fossil energy sources are not sustainable therefore it is imperative that renewable, less-polluting energy sources be identified and implemented into current energy markets. Renewable energy sources are needed to address a range of important economic and environmental issues and to insure a continuous energy supply.
