Heather Mills McCartney has urged people to drink milk from rats and dogs to help save the planet.
At Speakers Corner in Hyde Park, central London, she said: "There are many other kinds of milk available. Why don\’t we try drinking rats\’ milk and dogs\’ milk?"
Errm, how about this one? We\’ve bred, over the past few thousands of years, certain animals to be efficient at milk production. Cows, goats, sheep, camels….not only have we bred for volume of milk production but also for length of lactation: the production of milk carries on far past the weaning of the infants.
Another thing: how many rats would you need to provide the same volume of milk that a cow does? Err, if I\’m reading this right it\’s 8 grammes per day (1 gramme per pup with an 8 pup litter). Again, if I\’m reading this right then a cow produces 7,000 kg of milk in a year (I\’m sure that milk production figures vary wildly but that\’s the first figure I found). That\’s near enough 20 kg per day (actually slightly higher for the period of lactation but still….).
So, to produce the same volume of milk we either need one cow (plus associated calf) of we need 2,500 rats plus their associated litters.
Errm, average weight of cow, 1,400 lbs.
Weight of female rat, 200 grammes. Or fo 2,500, 500 kg, or 1,100 lbs.
Hmm. Now that does surprise me, that the total weight of rats is lower than that of a cow for the same volume of milk production. And no, I\’m not going to try and compare the feed requirements.
Still got that little problem of how to milk 2,500 of them twice a day though, eh?
