A4.2 - Non-technical Summary
Treble sykes Poultry Farm has FIVE poultry houses with a total of 141000 bird
places designed for rearing chickens for meat production. Birds are brought in
from a hatchery and are transported to a processing plant at the end of the
growing period.The average cycle length is 50 days.
The three 19,000 place poultry houses are 25 , 23 and 19 years old, built of
wood, with a steelroof and sited on a concrete base. All walls and roofs are fitted
with the original insulation, which is still considered to be in good condition.
Ventilation is provided by ridge inlets and side extraction.
The fourth shed provides 40,000 bird spaces, is 17 years old, built of steel with a
steel roof. All walls and roofs are fitted with the original insulation, which is still
considered to be in good condition. Ventilation is provided by side inlets and
ridge extraction.
Shed 5 provides housing for 44,000 birds , steel with a steel roof hollow fibre
and composite panel insulation, ventilation side inlrets and ridge extraction.
Prior to the arrival of the day-old birds, the concrete floors in each house are
covered with wood shavings to a depth of 20mm.
The houses 1 - 4 are prewarmed to 31°C using cubo water water fed heater
units, the water is heated using 5 P+H biomass pellet boilers. LPG and oil fuelled
space heaters are also on site for infrequent backup heat.
Shed 5 having calor lpg fired indirect heaters
As the birds grow, the ventilation rate increases and the house temperature is
gradually reduced until the heaters can be switched off.
Feed is purchased from a feed mill and it is stored on site in
fully-enclosed galvanised steel bins. Diets are formulated according to the
Birds’ requirements and the stage of growth. Protein and phosphorus levels
are reduced over the growing period.
Water is provided via nipple drinkers with drip trays which are designed to
minimise spillage. This, together with good environmental control in the houses
helps to maintain good litter condition and hence reduce ammonia and odours.
Water use in each house is monitored daily.
Low energy lighting systems (led floodlights or fluorescent tubes) are used
throughout the site.
Birds which die during the production cycle are removed from houses each
day and the numbers are recorded. The carcasses are held in covered,
vermin-proof bins prior to removal by an nfsco approved contractor.
At the end of the growing period, all birds are removed from the houses and
the used litter is taken away from the site in covered vehicles and spread onto
local, separately-owned agricultural land. The empty houses arethen washed
anddisinfected ready for the next crop. The wash water is channelled to
underground collection tanks close to the houses and subsequently the contents
are spread onto neighbouring land.
These measures are intended to reduce the production and emission of
ammonia, dust and odours and to prevent liquid washings escaping to the
environment. This in turn should reduce the environmental impact of the
farming activities.
Wood pellets are stored in fiberglass silo ‘feed’ bins, delivered by blower wagons
Ash produced by the boilers is auger fed into steel hoppers and spread on the
land with the manure.
