The total annual value of keeping growing pigs (TVGP) can be estimated using the following formula:
TVGP = (BV + DV) - CGP
where
BV is the sale value of a
pig less the purchase cost
DV is the value of
manure, and
CGP is the cost of keeping a growing pig.
The annual costs of keeping growing pigs (CGP) can be calculated using the following formula:
CGP = n (g + h + l + v + w)
where
n |
is the number of pigs |
g |
is the cost of feed |
h |
is the cost of housing |
l |
is the cost of labour |
v |
is the cost of maintaining health, and |
w |
is the cost of disposing of waste |
