Why do we drink cow's milk and not pig's milk...? We are, after all, very similar to pigs (both being omnivores and having similar internal anatomy and physiology):
I came across an interesting response/reason, written by a representative of the Illinois Pork Producers Association to a query letter from Guy Petzall (a guy who became well-known for writing to companies asking strange questions) re. the possibilities of milking pigs.
'Porcine do lactate and their milk I will assume would taste great, because it is made of 8.5% fat in relation to the fat that makes up 3.5% of the components in cows milk. The other components such as lactose and water are found at nearly the same percentages in pig's milk. However, pigs will on average produce 13 lbs of milk in a day as compared to cows that produce 65 lbs of milk on average per day. Pigs unlike cows cannot become pregnant while lactating and therefore possess a severe economic problem to producers. While pigs consume less feed per day, economics does not allow pigs to be a viable source of dairy products.
The biggest challenge facing the porcine dairy industry is collecting the product. Pigs on average have fourteen teats as opposed to cows that have four teats. Pigs also differ from cows in their milk ejection time, a cows milk ejection is stimulated by the hoimone oxytocin and can last ten minutes, where as a pig's milk ejection time only last fifleen seconds as the suckling pigs stimulate the release of oxytocin. The technology of a 14 cupped mechanized milking machine that can milk a pig in 15 seconds is not available to pork producers.'
Is this the only reason we don't drink pig's milk, or could it be because of ancient dietary rules which saw the pig as unclean...? Has anyone tried sow's milk or would you even try it? And is this a joke, or not - horse milk? If it is true, would you drink mare's milk? Please let me know what you think.....
I'll let you know the reason for my sudden interest in milk in the next post....
