This stage is a little longer, as marked by this line, it lasts for more than two months, but during this time their food will gradually increase, the same, their weight will also grow rapidly, and by the hundredth day or so, then such a duck will generally exceed three catties!

Of course, if we adopt the feeding method carefully researched by Zhangjiazhuang, we can make them weigh up to four catties! But after this stage, into the maturity period, duck food consumption will not be reduced, but their growth will become slow, it can be seen that this stage for duck input and output has been disproportionate, unless wait until the egg is laid, otherwise the previous benefits will all be consumed at this stage! ”

"Can you say it slower?" The eldest grandson heard a little taste, but she was still in a vague stage of the overall explanation, so she said to Zhang Yi: "Bengong just listened, the several periods you marked are all based on the growth of the duck to make a judgment, and you mentioned that the key is the growth of the first two stages.

If I'm not mistaken, you're trying to tell Your Majesty that you can make money in the first two phases, and you will lose money in the third phase, right? ”

Zhang Yi nodded helplessly, there was no refutation of the eldest grandson's words, and of course there was no way to refute it.

Because this is what he meant, and he also deliberately talked about the feeding method of Zhangjiazhuang, the purpose is to highlight the growth effect of ducks in the growth period.

At that moment, Zhang Yi smiled and said: "What Niangniang said is right, this is what Xiaochen meant!" However, many people may think that as long as they pass the later maturity period, then the female duck can lay eggs, so as to achieve the purpose of profit, and at present, almost all farmers use this method! ”

"Not bad! Chickens lay eggs, eggs lay chickens, that's the truth! Li Er said in a deep voice: "Let's eat a duck now, there will be fewer more ducks in the future, and I really don't know how many ducks have been lost in this cycle!" In an ordinary farmer's house, unless the duck is no longer old, it is impossible to slaughter it like you! ”

Zhang Yi was a little depressed!

If a duck is raised until it dies of old age, God knows how much time, energy and food will be wasted. Is it just for a few duck eggs?

Don't they know the pros and cons?

After thinking about it, Zhang Yi decided that in terms of intermediate interests, he needed to explain it to Li Er. If an emperor thinks which of the most backward breeding methods is used for breeding, then the people of the whole Tang Dynasty don't know how many years they have to wait if everyone wants to eat meat once a month.

Thinking of this, Zhang Yi's face also became serious, and he said solemnly: "Your Majesty, these methods of raising ducks by ordinary people you said are not only useless in the eyes of the ministers, but even a real waste!" ”

"Huh?" Li Er was taken aback and asked, "What do you say?" ”

If Li Er only thought that the reason why Zhang Yi said this was just to excuse himself, but when he heard it now, and looked at Zhang Yi's expression at the moment, he couldn't help but think that maybe there was really such a thing, so he also had some expectations.

After all, Zhang Yi's remarks in the morning have proved that he is not a simple gentleman, on the contrary, he is even a young man with a smart mind and does not stick to normalcy.

And what such a person represents is innovation!

As an emperor, Li Er is very aware of the importance of innovation, if you can't innovate then it represents backwardness, for thousands of years in China, the way of ruling the soldiers, agriculture, commerce and even the imperial court are constantly changing, the old aged, useless things are gradually replaced by advanced methods, and these advanced methods are the driving force to promote social development.

"Your Majesty, in fact, this is very simple, once the minister calculated an account for the breeding of chickens and ducks, and finally came up with two results!" Zhang Yi stood up and said to Li Er: "The first result is to raise roosters or ducks, because they can't lay eggs, they will definitely lose money, I don't know what Your Majesty thinks?" ”

"Yes, that's exactly what you say!" Li Er confirmed Zhang Yi's statement.

As Zhang Yi said, whether it is a rooster or a duck, not being able to lay eggs means that there is no output, and even because it has grown to the extreme, it is almost negligible to want to grow meat in the later stage of feeding, even if it grows some, it is really not cost-effective for the food consumed and various resources.

"The second result is that even if a hen or a duck is raised for a long time, even if it lays eggs, if you raise this kind of broiler duck or broiler chicken that is specially used for food during this cycle, the value it produces will still be much lower!" Zhang Yi said sincerely: "It takes more than 8 months for a duck to lay eggs from the beginning of hatching, and it takes a year for longer.

We take an average of ten months, so if we raise meat ducks in these ten months, we can breed 3 batches! In other words, when an egg-laying female duck can help us create profits, in fact, we have already made money three times by breeding meat ducks!

The price of a duck is about five cents, and we price a meat duck that we eat now at twenty-five cents, and if the cost of labor and grain is five cents in the middle, then we can earn fifteen cents for a duck. And in three batches, we can earn forty-five dollars!

In this way, the middle people can not only quickly return to their capital, but also provide a large amount of meat for the society, so as to change the current situation that it is difficult to eat meat once a month! ”

"Although I don't know much about farming, I still know that a duck egg now seems to cost a penny, right?" Li Er couldn't help but look at the guard next to him.

"Back to Your Majesty, an egg or duck egg in the market is about a penny!" The guard immediately replied, "The youngest child in the villain's family often eats eggs, so he knows the price very well!" ”

Li Er nodded, and then turned his head to look at Zhang Yi again, and said with a smile: "Boy, do you hear, an egg costs a penny, so a chicken can lay thirty eggs in a month, that is to say, as long as the chickens and ducks are raised to the point where they can lay eggs, then they can bring thirty wen to farmers in a month." ”

Li Er didn't continue, but the meaning was already very clear, if a month could bring thirty Wen input, then what about two or three months later?

Obviously, in his opinion, although there seems to be no return in the front, but in the later income, in the long run, then it is more cost-effective to breed chickens and ducks with eggs!
