^ Outputs of roughage and forage are expressed as tons of silage or hay and animal 

 units grazed (mature cow equivalents). Head equivalents for livestock species in- 

 volve summations based upon the carrying capacity of roughage and forage output, 

 full-season pasturage being included at the rate of 0.4 unit, and roughage output 

 (silage and hay) at the rate of 0.6 unit. Consumption of hay (alone) was estimated 

 at 3.0 tons per cow, 4.0 tons per horse, IM; tons per head of youngstock, and 700 lbs. 

 per head of sheep. 3.3 tons of silage were considered equivalent to one ton of hay. 

 Carrying capacity of pasture varied with condition, but on pastures of equivalent 

 quality — one cow or one horse per X acres — it was estimated 1.33 head of young- 

 stock or 5.0 sheep could be carried. Brush and woodland pasture was generally valued 

 at the rate of 10 acres per cow or horse, 7 acres per head of youngstock, and 2 acres 

 per sheep; open improved pasture at the rate of 3 acres per cow and 2 acres per 

 head of youngstock; improved pasture, pre-construction, 1.5 and 1.0, respectively; 

 and improved pasture, post-construction, 1.0 and 0.7, respectively. Variations from 

 these occurred under some circumstances. Hay and silage yields per acre were vari- 

 able, but were translated from tons to animal units by using consumption rates 

 previously given.
