Roll on chemical can cut pig smells say US scientists.

SCIENTISTS from the USA Agricultural Research Service (ARS) have discovered that aluminium chloride, a common ingredient in deodorant, helps lessen foul odours emitted by pig farms. Soil scientist Philip A Moore, Jr. found the compound is effective when applied to liquid waste and does not generate smelly sulphuric gases, unlike aluminium sulphate which is currently used. Moore also discovered the aluminium chloride significantly decreases ammonia emissions generated when hundreds of farm animals are raised under one roof. The ARS said this is significant because intense atmospheric ammonia concentrations threaten the respiratory health of livestock and meat production workers, while damaging water quality through atmospheric nitrogen deposition.
