Chao-Huei -- Another explanation could be that you can't compare  cc's of breast milk to cc's of cow's milk.  Babies on cow's milk drink increasing quantities of milk the first few weeks of life, and in much more quantity than a breastfed baby.

For instance, colostrum amounts are very low, at first, while the formula fed newborn takes anywhere from 15-60 cc per feeding.

Maybe a better approach would be to figure out how many cows would it take to feed how many babies for a year.

Subject:        ecological impact of BF,population of India women(urgent)

Hi all:
I had read about "The ecological impact of bottle-feeding" from
Breastfeeding Revies, May 1992. It was said that to replace the milk of the
women of India alone would take 135 million lactating cows. I used the
statement in my lecture but people of the diary industry told me that one
lactating cow will produce over 18 Kg cow milk a day. For 135 million
lactating cows a year(300 days), they will produce over 800,000,000,000 kg
cow milk. They didnot think that India women could produce so much milk and
they criticized the above statement. In that paper, the reference came from
" Calculations based on information in Jelliffe, op. cit. and in UNICEF,
op.cit."  I can't find that reference in Taiwan.
I think of one explanation may be that "not one Kg cow milk produce one Kg
formula milk". The numeber of the lactating women in India may be another
explanation. I need both facts urgent to persuade people. Any information
will be highly appreciated.

Please e-mail to me private because there is lag in my reading Lactnet.
