Bedding Even the cleanest of straw will contain more fungal spores than alternative beddings such as wood shavings, paper or hemp beddings. Deep litter beds should be avoided as significant moulding can occur, in addition to the build-up of ammonia and the larvae of gastrointestinal parasites. Ammonia Ammonia released from a deep litter bed or poorly managed bedding where damp patches are left, can seriously damage the horse’s airways and reduce the efficiency with which the horse copes with other respiratory allergens such as fungal spores. Top Tips to Reduce Respiratory Challenge • Choosing a dust-free bagged forage in place of hay will probably make the single greatest contribution to reducing the respiratory challenge to all stabled horses and ponies. • Always feed high quality, dust-free feeds. • In addition to the points above, in severely affected horses and ponies, medication may be necessary to control the respiratory disease, so veterinary advice should be sought in this instance. • The importance of antioxidants in lung health has also been highlighted. Horses suffering from RAO (Recurrent Airway Obstruction) may have disturbed oxidant-antioxidant equilibrium and there are special antioxidant supplements on the market aimed specifically at horses suffering with RAO. For advice on feeding your horse or pony or for further information on a range of dust-free forage and feeds, please call the HorseHage Helpline on 01803 527274 or visit: www.horsehage.co.uk • Straw bedding and all forms of deep litter should be replaced with a dust-free option but will still require good management. • Good ventilation is essential. An extra rug is definitely preferable to closing the top stable door. • Siting of stables is important and should be away from your hay store/barn or muck heap or the pollutants will carry past the stable door. If in a multi-horse yard or livery, there is little point trying to control the environment of one horse if, in a shared airspace, there is another horse next door eating hay and which has a straw bed.
