The meat index is a very important indicator, and it occupies a very important position in determining the people's livelihood indicators of the navy.

The proportion of meat in the Dinghai Navy began to increase from the beginning of the establishment of the Dinghai Navy, in the beginning, it was almost sparing no effort to collect all kinds of meat, no matter what it was, as long as it was meat, as far as possible to the Dinghai Navy, in order to ensure the proportion of meat in the entire Dinghai Navy.

Ding Navy is very rich, starting from the Daimyo Blacksmith Workshop, Ding Navy signed a contract with the Privy Council of the Northern Song Dynasty, responsible for the iron of the entire Privy Council, which is tens of millions of investment, this part of the Ding Navy under the strong production capacity, the profit is very considerable.

With such a big profit, of course, you can buy it casually, but at that time, when the Dinghai Navy purchased all kinds of meat, it was not so smooth, even if all kinds of meat in the entire Northern Song Dynasty were expensive, it was impossible to fully supply the needs of the Dinghai, and the reason for this was very simple.

The Northern Song Dynasty has formed an inherent supply and demand structure, in the absence of large-scale farms under the premise of the rise, even if the demand rises, it is impossible in a short period of time, large-scale volume out, buy more, buy more, the price will naturally rise.

At that time, the output of the Northern Song Dynasty, even if Zhao Xin bought the meat of the entire Northern Song Dynasty, may not be enough to determine the use of the navy.

Chinese are not very suitable for eating fish, because this is not the most common meat, but when there are no and there are these two options, as long as it is meat, it is acceptable, not to mention, it is still a relatively good sea fish.

It is precisely because of the large number of purchases and collections, Zhao Xin studied the results of the Northern Song Dynasty meat, and he understood why in the past, meat was so expensive, under the premise of no feed, meat, either fed with grain, or, for many years, with all kinds of things and labor piled up, in the absence of a scientific breeding method, 10 to 1, or even 20 to 1 meat yield, is very normal.

Don't talk about rice, just say it's ordinary grains, a pound of 3 Wen, 20 to 1, a pound of meat is also 60 Wen, plus disease, loss, and a series of necessary expenses such as slaughtering and transportation, the price of pork is about 100 Wen, it is also normal, there must be profits, otherwise, who raises it.

This is not only the norm in the Northern Song Dynasty, but also the norm in the whole world and most countries, that is, after the emergence of corn and the emergence of a large number of cheap feed, which changed the status quo.

Meat is just a process of exchange, and food must be provided in order to grow meat, and the price of this meat is directly related to the provision of this food.

Before Zhao Xin, he wanted to do centralized breeding, but he couldn't solve the problem of feed, which has always been a huge problem, but even if it was difficult and hard, he never thought about stopping and not introducing all kinds of meat.

The reason is very simple, Zhao Xin, who has come from later generations, knows very well that protein is a huge thing for a person's improvement, which not only affects the growth of people, but also directly adjusts the human race, which is beyond the reach of others.

Among all the non-staple foods consumed, meat is the most delicious, even children who don't know anything like to eat meat, because most of the delicious food is provided by fat, and the more fat, the more fragrant the taste of the dish.

Zhao Xin has a clear understanding of this intake, perhaps, adults he can't influence, can only gradually influence, but in infants, it is necessary and mandatory to popularize eggs and milk.

Two glasses of milk a day in the morning and evening, 1-2 eggs a day, this is an inevitable recipe for children over 3 years old, for which he even used state subsidies to eat this, and some welfare benefits are linked.

Dingjun has a total population of more than 80 million, of which children under the age of 12 account for more than one-third of the overall proportion, for the simple reason that most of them were born in the last seven years.

In the early stage of the development of the Dinghai Navy, in order to develop the Dinghai Navy, in order to feed hundreds of thousands of people, in the same way, these laborers were also in order to let the family live a good life, when there was a shortage of labor, not to mention men, women, and half-grown boys, they had to work, at that time, there was no effort to consider the problem of having children.

However, with the passage of time, the influence and strength of the Dinghai Navy are expanding, for example, the production of various machines, reducing the basic labor consumption, and for example, the production of assembly lines, as well as various professional equipment, so that the use of labor is greatly reduced.

Similarly, the population of Dingjun is also increasing, bringing more labor population, adult men are much taller than women and children in all aspects, and Zhao Xin will not choose to dry up and fish under the premise that the labor force is not so tight.

Children are the first to leave the front line of labor, from the age of 15, until now, reduced to 18 years old, in fact, if according to the current Dinghai Navy, relatively complete primary school, junior high school, high school, technician and university training, technicians come out, at least 20 years old, as for the university, divided into 3-5 years, as little as 21 years old, more than 23 years old.

After children, and then there are women, the labor force of adult women is just a little worse than men, and even in some special industries, it is more suitable than men, but Zhao Xin's vision is very far-sighted, and he directly sees the benefits of population growth, even if the labor force is a little worse, he will not choose this, and even to a certain extent, in order to reduce the employment rate of women, he pushed the project of textiles, which can make money, to the Northern Song Dynasty.

Full of warm thoughts**, this sentence seems to be a bit excessive, but in fact, for the Dinghai family with a guaranteed life and a promising future, it is really like this, coupled with the many incentives set up by the Dingjun, the population growth rate of the Dinghai has always maintained a high level.

At the time of Dinghai Island, the limit even reached an annual growth rate of 13%, when there were more than 10 million people and more than 2 million newborns per year.

In Liao, under the premise of occupying a large amount of territory, a population plan was implemented, and more than 40 million people were immigrated at once, and the growth of the population made the total increase, and this part of the new population could not have children at once, they would work gradually, and after the economy improved, they would also have children.

This can be seen from the birth figures, in the year when the migration was completed, the fertility rate dropped from 13% in the previous year to about 9%, which is a very significant decline.

However, in the following year, along with these immigrants to the Dinghai Navy, they had stable jobs and were familiar with the many regulations and rewards of the Dinghai Navy, and they had nothing else, that is, to have children.

From the beginning of the population of 20 million, with an average annual fertility of more than 2 million, to the beginning of the fourteenth year of Qingli, the population of 85 million, with an annual fertility rate of 12%, almost gave birth to a population of 10 million.

In less than 10 years, more than 50 million new newborns have been added to the Dinghai Navy, and the total population of the Dinghai Navy has also grown rapidly from 85 million to 140 million.

More than one-third are newborns, plus the original teenagers under the age of 18, the total number of adolescent babies may exceed 70 million, which is basically half of the population of Dinghai.

This part is the focus of Zhao Xin's attention, and even unceremoniously said that after the establishment of the Dinghai Navy, these people who were born in the Dinghai Navy and grew up in the Dinghai Navy will work and study in the future or in the Dinghai, and the growth of these people will not only have more sense of belonging to the Dinghai Navy, but also play a vital role in the future of the Dinghai Navy.

When the total amount increases, even a small percentage increase, it will greatly improve the overall quality, not to mention tens of millions of babies, which must be guaranteed.

Milk and eggs, two things that seem simple, but they are the foundation of physical fitness, far more than other things.

Even in the 21st century, the quality of the race, is also these two things to improve very quickly, Japan in the period of development, the height of school-age children is very short, all aspects of the quality is not good, is to rely on a cup of milk, an egg, improve the overall quality, persisted for more than 20 years, the Japanese short is no longer a large-scale thing.

Physical fitness is not only height, body, longevity, intelligence, but also a series of other things, which is a comprehensive improvement for people in a country.

But now, with corn through a certain method, the processed feed, can basically preserve most of the nutrients of corn, at the same time, not too heavy.

Mixed with a certain percentage of other things, the feed becomes the favorite food of all kinds of animals, which becomes the basis of breeding, and is already produced in the year when the corn is harvested on a large scale, and in the next two years, with the increase in the weight and quality of the corn, and constantly increases.

Zhao Xin also knew that in later generations, local eggs were popular, and free-range chickens were popular, but at that time, under the premise of great social material abundance, native eggs were better in quality and better performance than ordinary eggs, but they were far from being at a good price, and the price of a local egg that was not as large as half the size of an ordinary egg was more than twice that of ordinary eggs, which was equivalent to a fourfold difference.

The current Dinghai Navy, the first thing to solve is the problem of having and not having it, and then we can take into account the problem of improvement, you are all poor and white, you can't even afford to eat, there is an egg, not a native egg, you are not late, that is an idiot.

The emergence of feed, so that large-scale raising of chickens and ducks, has become possible, lighter feed, can also reduce the labor force on a large scale, if with some machinery and equipment, it will be even better.

Dingjun, long through the Animal Husbandry College, summed up a series of know-how of raising poultry, and now, with feed, after solving this big problem, immediately started a large-scale promotion.

For a time, poultry farming began to surge, and at the same time, various eggs began to appear on a large scale.

In addition to eggs, milk and goat's milk, etc., also began to appear on a large scale, if there is not feed, there is enough feed with a variety of proteins added to the top, simply eating grass, it is very easy, it will make cows malnourished, this is no way, cows can not make milk out of thin air,

They have to eat, they have to digest and absorb it, so that they can be transformed. If you just ask for it for a long time and don't compensate for it, it is easy to make the cows lose money, and once the deficit cannot be reversed, it is easy to have problems.

It takes at least several years for a cow to grow from a calf to a milk-producing calf, and in these years, he has only input, not output.

Farmers can't let these cows die because of milk production, there is no way, only to produce milk in stages, in this case, not only the amount of milk produced is limited, but also the price is quite expensive.

Such a cow, or a sheep, can produce very limited milk, so in China's feudal era, cow's milk and goat's milk, that is a large family, is eligible to enjoy, and even some royal princes, not everyone can enjoy.

If Zhao Xin had chosen to use milk as the best way to improve the system for infants and even teenagers, even if all the milk of the entire Northern Song Dynasty and Liao Kingdom had been concentrated in Dinghai, it would probably have been impossible to feed the newborns of the entire Dinghai Navy, let alone all teenagers and infants.

At that time, Zhao Xin also considered popularizing some feeding methods for dairy cows, but with a little intervention, he knew that it was impossible, cows will consume a lot of energy when producing milk, and generally cows begin to accumulate from the beginning of pregnancy, so that in the early childhood of calves, they can be supported.

But in the sense of later generations, from the beginning of milk production, it has been down non-stop, so that the consumption of dairy cows is very large, if there is no high quality, good effect of feed appears, simply eat grass, may not stop eating all day long, but also not enough, once a large-scale loss, I am afraid that the cows will accumulate heavy and unbearable.

However, the emergence of corn feed has solved this problem, although not all, but adding a certain amount of fishmeal and soybean meal to get it out, it will solve all the problems.

This is the essence of the way, to improve the entire supply structure, the emergence of feed, is a huge change in the feeding model, large-scale intensive breeding, high efficiency, more meat, but less input, this is the role of feed.

If it is on the meat, the feed has shown a huge effect, in the egg production and milk production, it has also produced a huge effect, especially milk production, as long as it is blended, the concentrate feed and roughage are cooperated, you can make the balance between eating and production, so that the milk continues to produce, so that the output will be greatly improved, which is the most correct way to open the milk.
