I want to start with this thought :
people have no right to inter fair with other people habit to Eat beef or drink milk its people choice…I do not eat beef I drink milk other want to eat can eat…its there choice….
Economics of Cow: interestingly it points to use of word Holy Cow.
I went to see data on avg a cow U.S. weighs 1350 pounds
100-pound increase in mature weight a cow requires an additional $15 – $20 in supplementation costs.
cost per kg: $23.83, Value per cow:
(1350X23= 31050 dollars) ………………………..equation 1
While if cow is kept for milk Each year:
Milk production per cow: a range of around 6,800 to 17,000 kg per year
avg say: 12000 kg .(source:http://en.wikipedia.org/wiki/Dairy_cattle.)
Value if market of cow if traded for milk:
milk production X per litre cost.(1 dollar per litre)
= 17,000 dollar per year.
Now cow lives and gives milf another 15 yrs So total cost= 17,000X15=3,50,000 dollar ………………………equation 2
from equation 1 and equation 2:
value of Meat Expert : value of milk export= 31,000 :(is to )3,50,000
Like benefits are in ratio: 1(beef): 11(milk).
11 times it more better to utilize cow for milk then for beef.
(cost of maintenance remain same in both cases and makes almost no impact)
What Is Compounding Effect here ?
of Each time 1 animal killed its compounding is stopped. While when utilized for milk each year animal population increases leading to more production and very minimal increase in marginal cost..
Beef: Each year a new animal brought and cut.
Milk: Each year last year animal still remain.(1/1, 1/2, 1/3,1/4……… 1/n) total after 15 yrs 15/15 .
Second year production double, 3rd year increase by (3-2)/2, 4rt year (4-3)/3….
each year production increase by 1 more animal sum of all for 15 yrs (1,2,….15)= 15 X16/2= 120.
120 X 11(factor for 1 cow)=1320 times more profit in 15 yrs….
