We all know that dairy products contain a large number of proteins, vitamins and various mineral elements necessary for the human body, and the absorption rate and utilization rate of these elements are very high.
Therefore, as long as the discomfort is lactose intolerant, or there is no allergic reaction to dairy products, drinking milk appropriately can enhance immunity.
In the choice of dairy products, we often see all kinds of milk, goat milk, but it seems that few people will think of pig milk?
Pigs can also produce milk, so why doesn't anyone drink pig milk?
Pig milk, what does it taste like?
The taste of pig milk varies, some people think that pig milk tastes like some faint almond taste, which is acceptable, but some people think that pig milk is thinner than milk, and the taste is more fishy than goat milk.
On nutrition, the fat content of pig milk reaches 8.5%, which is richer than the fat content of milk 3.5%, and its protein, lactose and other content ratios are similar to milk.
Compared with the need for milk and the need for large-scale farms, pig breeding is not only convenient, but also almost all rural areas can raise pigs, but why is pig milk so scarce?
Drinking pig milk is actually not so easy
First, the milk milk milk time is slow
Due to the pig's breast duct segment, the milk tank used to store milk on the body is not developed, and milk cannot be stored, which means that pigs cannot store milk in their own milk pool in advance like cattle and sheep, so they can only "drink immediately".
The most important thing is that sows do not produce milk at will, and they only produce milk when they are stimulated by the action of feeding milk and the hungry cry of the piglets.
Therefore, the production of pig milk is many times lower than that of cow's milk and goat's milk.
Second, the yield of pig milk is low
Compared with cattle and sheep, the milking time of pigs is particularly short, generally only about a few minutes from the beginning to the end, and there is no more milking time for the milking staff.
In addition, pigs can produce two litters of pigs per year, the breastfeeding period is only two months, and the milk produced is about 600 catties. The cow's lactation period is 9 months, and it can produce 10,000 catties of milk a year.
Third, the cost of pig milk is high
Compared with cattle and sheep, the cost of raising pigs is relatively high.
Cattle and sheep are herbivores and are mainly raised forage. Pigs, on the other hand, are omnivores and need to be fed refined feed, which is more expensive to raise.
The high cost of feeding and the rate of milk production are very small, but if you directly sell piglets, the income obtained is many times higher than that of selling pig milk.
Milk and goat milk meet the human body's nutritional needs
The nutrients in pig milk are relatively high and the taste is slightly stronger, but there are also many nutrients in cow's milk and goat's milk.
And whether it is protein, calcium, amino acids, vitamins, and other types of mineral components, they can be well used by the body.
As long as the appropriate supplement of about 300ml of milk or goat milk per day can fully meet the body's needs for various nutrients. If you drink pig milk with high nutrients, it is very likely that people will have overnutrition, which is not good for the body.
Milking pigs is not an easy task
Due to differences in physiological structure, pigs have a large number of nipples, with an average of 6-7 pairs of nipples, and they are distributed everywhere, so they cannot concentrate on milk like cattle and sheep.
Of course, the most important point is that cattle can make you use them as you like, but pigs are not so docile.
Sows have a more violent temperament after childbirth than cattle and sheep, and if they are forcibly milked, it is very likely that some unexpected dangers will occur, such as being chased and bitten by pigs, and even some breeders will be bitten by sows to the point of blurring flesh and blood.
Therefore, after comprehensive consideration, pig milk is not a good choice.
What about other animal milk like mare's milk, camel's milk, etc.?
Compared with milk, the rest of the animal milk is more or less defective, the pig milk production mentioned above is small, it is difficult to milk, the goat milk is relatively fat, the camel milk is somewhat salty, and the horse has too high requirements for the growth environment.
Even donkey milk, which was previously fried hot, has not yet reached half the protein and calcium content of milk.
Therefore, for animal milk, milk is also the best quality choice.
Of course, pigs are not without advantages, and the fragrant meat that people bring with them is the best choice on the human table.
