Model for estimating feedlot manure quantity and nutrient content - Saskatchewan references

Manure production

There have been several attempts to quantify feedlot manure production in Saskatchewan (table 1). These studies may be regarded as "extension projects" rather than peer-reviewed academic data. In all cases, mass was estimated by weighing trucks as manure was removed from the feedlot. In all cases, data represents fall manure removal once each year. Both moisture content and manure production in Saskatchewan are greater than that predicted by American references (table 5).

Table 1. Saskatchewan manure production, as-removed, wet-basis, average.

Source Animal Weight
(kg)
Moisture Content
(%)
Manure Production
(kg head-1 d-1)
Feedlot A, PAMI, 2000   42.1 9.7
Feedlot B, MA, 2000 408 51.3 16.2
PAMI, 2002 454   14.2
Feedlot C, MA, 2006 458 59.2 13.5
Manure Properties, MA, 2013 491 52.4 13.6

Nutrient concentration

Far more data is available on nutrient concentration than manure production. Manure removal studies in Saskatchewan provide several values for nutrient concentration, and data is also available from Alberta (table 2).
