Winter Silage Requirements for Cattle
Monthly Silage Consumption per Animal
Cows -- 1.4 tonnes per cow per month
Cattle 1 to 2 years -- 0.8 tonnes per head per month
Cattle 2 to 3 years -- 1.2 tonnes per head per month
Stock Bull -- 1.2 tonnes per head per month
Example:
5 months of winter feed is required for all stock except the 2-3 year old cattle, who require 3 months supply due to being wintered later and finished indoors.
60 No. cows @ 1.4 tonnes/ cow per month = 84 tonnes/month
1 No. bull @ 1.2 tonnes/bull per month = 1.2 tonnes/month
30 No. 2 - 3 year olds @ 1.2 = 36 tonnes/month
30 No. 1 - 2 year olds @ 0.8 = 24 tonnes/month
(109.2 x 5) + (36 x 3) = 654 tonnes
Since 1 hectare produces approx 20 tonnes, 654/20 = 33 Ha
Therefore 33 hectares of silage would need to be cut.
