Table 1 – Regulations 9(3), 10(4) and 16(6)

The nitrogen excretion rate for livestock

Unit of livestock categoryProduction period or Age rangeBody Weight kgOccupancy % of year(1)Annual Nitrogen Production kg N
(1)

For individual farms where occupancy values differ from those given, nitrogen excretion values should be altered accordingly.

(2)

Use the suckler cow data for beef and dairy bulls.

(3)

Maiden gilts, assuming all year round accommodation.

(4)

Sows based on 2.3 lactations, covering 23 per cent of year and dry period 77 per cent of year. Combined output 19.5 kg N/sow/year.

(5)

Broilers, output per 6.6 crops/year, 40 day cycle (73 per cent occupancy).

(6)

Broiler breeder replacements, output/24week cycle. Where there is more than one cycle per year adjust the output figures proportionately.

(7)

Replacement pullets, output per 20 week cycle. Where there is more than one cycle per year adjust the output figures proportionately.

(8)

Turkeys, assuming 2.1 or 2.4 crops per year, for male and female birds respectively.

Annual nitrogen application standards for grassland crops

This table does not imply any departure from regulation 9(2) or 10(3) which prohibit the application to the agricultural area on a holding of livestock manure in amounts which exceed 170kg N/ha/year, including that deposited by the animals themselves.
* The Dairy Cattle figures (dairy cows and heifer replacements) apply where it can be demonstrated that more than 50% of the livestock manure applied to the agricultural area, both by land application and by the animals themselves arises from dairy cattle. In all other cases the figures for Other Livestock will apply.
