'Livestock and poultry' wastes could produce significant amounts of bI energy if conventional energy prices continue to rise.. This study ettiros the recover/able energy potentially available from livestock and poultyy wateo in the southern United States in 1980 with projections for 1990 • The pcItentlal . energy from anaerobic digestion (JE dairy cow, hog, fed beef, and laying hen manurcs was 20.6 billion cubic feet of methane gas in 1980 with 20.6. trillion Btu's of enc!rgy; only slight increases are projected for 1990. Diroct burning .of litter from broilers, turkeys, and pullets could have produced 43.7- trirnon, Btu's of energy in 1980 with 58,6 trillion Btu's projected for 1990. The total potential farm value of biomass energy from these enterpries ranged from $141 to $446 million in 1980 and 43/40 million to $1.08 billion in 1990 depewling upon the types of conventional energy displaced. Biomass energy valuas ria highest when substituted for LP gas.
