Da Qin: Comparing his sons, Ying Zheng was sour.

[Passing through the Forestry Division, Qin Wang Yingzheng and Prince Fusu and others continued to the Animal Husbandry Division, one of the six divisions of the Ministry of Agriculture, which is mainly responsible for researching and optimizing the breeding methods of various poultry and livestock. 】

["Your Majesty, Your Highness, please see, this is the Animal Husbandry Division. "】.

["According to the different types of livestock, we are also divided into different livestock farms. "】

[For example, we have corresponding farms here for the common six animals: cattle, horses, sheep, pigs, dogs, and chickens. "】

["Each farm also has a team of peasant children who are responsible for raising and researching, and record the changes in the breeding of these livestock every day. "】

["Like the first thing we passed in front of us was the pig farm, the black man was fierce and aggressive, and ate a lot, and pulled a lot, and often made the manure everywhere in the field. "】

["So when you pass through the pig farm, the smell will be heavier, please forgive Your Majesty and Your Highness."] "】

[Xu Zi was still standing in front of him, leading the way, and introduced. 】

[And King Yingzheng of Qin and Prince Fusu also nodded slightly when they heard Xu Zi's words, expressing their understanding. 】

[And to put it mildly, no matter how disgusting the pig farm is, can it be more disgusting than the fertilizer group that specializes in all kinds of manure before?]

[In the past, in the face of the fertilizer group that studied all kinds of feces, Qin Wang Yingzheng and Prince Fusu were able to have no different colors and a calm demeanor, not to mention the smell of dung. 】

[In addition, there was Xu Zi's advance reminder, so when they stepped into the pig farm and smelled the peculiar smell of dung, Qin Wang Yingzheng and Prince Fusu did not show any different colors. 】

[Even King Yingzheng of Qin and Prince Fusu took the initiative to observe the black boys who were raised in captivity through the fence. 】

[Seeing this, Xu Zi on the side also opened his mouth to explain to the two: "Although Hei Yu is fierce and aggressive, it grows faster and bigger than a sheep. "】

["It's just that the smell of the black meat is relatively strong, and it is difficult to eat if you don't adjust it with heavy ingredients."] "】

["At present, we peasant children have two studies on Hei Yu. "】

["One is to study how to make the black one more docile and easier to keep in captivity. "】

["The other is to study how to make the fishy smell of the meat less strong and make it more accessible to the 757. "】

["It's just that there is no good progress in either of these studies so far. "】

[The crown prince Fusu raised his head, looked at Xu Zi beside him and asked: "Hei Yu usually fights for something, have the peasant children studied this clearly?]

[Xu Zi nodded and replied: "Yes, according to our observation and research, when Hei Yu is in heat and eating, it is most likely to fight. "】

["When there is a fight in estrus, there is a fight because there are many males and few females. "】

["Therefore, in order to compete for their own mother, and at the same time let other males know that they are strong, and also in order to show their strength in front of the mother, they will fight with each other. "】

["In this regard, we once thought about putting the same number of male and female in the same farm. "】

["In this way, a male can be paired with a female, so that those males no longer need to fight for the female. "】

["It's just that this idea failed in the end, because even if we put in the same number of males and females, once those males enter estrus, they will still continue to fight. "】

["And when there is a fight when eating, it is purely because some strong black robes want to eat more, so they will grab the food of other relatively thin black babes, and then fight with each other. "】

["In this case, we usually give Hei Yu more food. "】

["Or when feeding, use a fence to separate them vertically, so that each black bird can only eat its own food, and cannot compete for the food of other black birds. "】

["Barely it can also control and reduce the fights that occur because of the black robbers. "】

["In addition to these two most common and most frequent fights, sometimes when the black ones play with each other, they will suddenly start a fight. "】

["However, this kind of fight is not serious compared to the first two, and it is more similar to a kind of play. "】

[Prince Fusu stretched out his finger and pointed to the pig farm, which was lying in the corner and grew stronger, but his temperament was obviously more peaceful than the surrounding black boys, and asked: "Those few heads, are they the mother boys?"

["Isn't the mother's temperament more docile?"]

[Hearing the inquiry of the crown prince Fusu, Xu Zi thought like a monkey, nodded and said, "That's right, those heads are indeed the mother of the child. "】

["In addition, Mu Yan is indeed as His Royal Highness said, and her temperament should be more docile and not like to fight. "】

[After listening to Xu Zi's answer, Prince Fusu once again stared at those black boys who were fighting because of estrus, and gradually fell into deep thought. 】

[Seeing this scene, Xu Zi also looked at Prince Fusu with an expectant expression. 】

[Because before the prince Fusu invented the cocoon car and improved the quyuan plow, he also looked like he was thinking about things. 】

[After the prince Fusu came back to his senses, he immediately invented the cocoon car and improved the curved plow. 】

[Therefore, with the precedent of inventing the cocoon car and improving the Quyuan plow, Xu Zi immediately placed hope on the prince Fusu. 】

[After all, Prince Fusu is naturally intelligent, and they haven't been able to think of a solution to these two problems for the time being, maybe Prince Fusu really suddenly thought of it!]

[Not only Xu Zi is like this, but Qin Wang Yingzheng, as well as other accompanying peasant children, Mo family children and other personnel also focused their eyes on the prince Fusu, who bowed his head and pondered at this moment. 】

[Immediately, they all held their breath and didn't dare to speak again, for fear that they would interrupt Prince Fusu's thinking if they didn't pay attention. 】

[For a while, in the huge pig farm, except for the roar of the black boy, there was no sound of anyone else talking. 】

[After a long while, the prince Fu Su raised his head and said, "Castration!"

[Hearing the words of the crown prince Fusu, Xu Zi didn't react for a while, and muttered and repeated: "Castration?"

[Prince Fusu explained: "It's a prune!"]

["Since a male and a female are paired, it can't prevent the fight that happened because of the estrus. "】

["Then castrate the gong directly!"]

["Let Gongbi lose his descendants and descendants, and see if Gongyu can continue to estrus after he has no descendants and roots!"]

["I don't think I will continue to estrus, after all, the roots of the children and grandchildren are gone, what's the use of estrus fighting?"]

["At that time, the male should be able to be more docile than the female. "】

["And if there are fewer fights due to estrus, then Gong Yu will be able to eat long meat more with peace of mind, and maybe he can grow more meat!"]

[Hearing the words of the crown prince Fusu, the faces of everyone present changed slightly, and they faintly felt a chill in their crotch, and couldn't help but gasp quietly. 】

[After all, everyone present is a decent man. 】

[Even if it is a eunuch like Zhao Gao, he is not a eunuch. 】

[In the current era, eunuchs or eunuchs are still only a very small minority group. 】

[The so-called castration is more of a punitive punishment in this era. 】

[However, after a short period of surprise, Xu Zi thought carefully about what Prince Fusu said, and also felt that what Prince Fusu said was reasonable. 】

[After all, the reason why Hei Yu is fierce and aggressive is because of estrus and food grabbing. 】

[Let's not talk about grabbing food, they can barely control and solve this point. 】

[And if you are in heat, to put it bluntly, isn't it for the sake of your descendants. 】

[Directly remove all the roots of Hei Yan's descendants, what else does Hei Yu take to estrus?]

[And if you can't estrus, then the fights caused by estrus will naturally be controlled and reduced.] 】

[Thinking of this, Xu Zi was also about to move, looked at the crown prince Fusu and asked, "Your Highness, how do you think you should castrate?"

[Hearing this, Prince Fusu also said helplessly: "Master Xu, there is a specialization in the art industry, such a thing as Chopping, you should ask the butcher, the butcher is the real expert.] "】

[Xu Zi immediately patted his head, it was he who made a mistake. 】

[Prince Fusu's too superior performance not only made him ignore Prince Fusu's age, but even to a certain extent, made him regard Prince Fusu as an omniscient and all-powerful existence. 】

[Thinking of this, Xu Zi looked at the peasant children who were in charge of studying and raising black beans and ordered: "Later, you will find a few butchers who know how to castrate and castrate, and castrate and castrate one of the batches of black beans. "】

["Then observe whether the black biao after being castrated and castrated has become more docile, and whether there is any estrus fighting and other phenomena. "】

[A few peasant children who were in charge of researching and raising black birds on the side immediately nodded and responded: "Yes, Xu Zi!"

[And the prince Fusu on the side also gave his own advice again: "Those who want to be castrated and castrated, it is best to choose black ones that cover all different ages. "】

[For example, a black bi that is five days old, a black biao that is ten days old, and a black biao that is fifteen days old...... Until the birth of two or three months of black bi. "】

["Look at the different growth stages of castrated and castrated black bis, what are the differences in their growth. "】

["From this, we compare and select a castration and castration that has the least impact, the black bomb recovers the fastest, and at the same time will also grow the most fleshy castration and castration time period in the future. "】

["In this way, in the future, in a certain period of time after the birth of the black boy, the black bomb can be castrated and castrated. "】

[Several peasant children who were in charge of researching and raising Hei Yu also nodded towards the crown prince Fusu and replied: "Yes, Your Highness!"

["We must find the most suitable time period for castration and castration of the black boys!"]

[After speaking, several peasant children who were responsible for researching and raising black birds discussed with each other, and then divided labor and cooperated with each other. 】

[In the end, two of the peasant children who were responsible for researching and raising black birds continued to stay here, responsible for finding out the black birds who were going to be castrated and castrated.] 】

[And the other three peasant children who were in charge of researching and raising black birds walked out quickly with great interest, preparing to go outside Shanglin Yuan to find a few butchers who knew how to castrate and castrate. 】

[After all, there are six princes in Shanglin Yuan, but no one knows how to castrate and castrate the black boys. 】

[After walking out of the pig farm, King Yingzheng of Qin looked at Prince Fusu and asked, "How do you know about castration and castration?"

[It stands to reason that Prince Fusu is only six and a half years old now, and he should not know about castration and castration. 】

[Of course, King Yingzheng of Qin didn't think that the crown prince Fusu couldn't know about castration and castration. 】

[Instead, I feel that Prince Fusu is still young now, and I am worried that Prince Fusu will know these miscellaneous things too early, which will have a bad impact on Prince Fusu. 】

[The crown prince Fusu didn't notice the hidden worries under his father's words, and replied directly and briskly: "What I saw in the book, those peasant words taught by Master Xu before have briefly talked about this aspect. "】

[Qin Wang Yingzheng nodded slightly, and did not continue to talk about this topic. 】

[After all, no matter whether the prince Fusu at this age should have touched or seen the content of castration and castration, now the prince Fusu has been exposed to it and has finished reading it. 】

He does not waste time on things in the past that have already happened and cannot be changed. 】

[However, for the words of the other princes and hundreds of schools that the prince Fusu will learn in the future, should he review it in advance, so as not to let the prince Fusu continue to learn some messy content by mistake. 】

[This point was kept in his heart. 】.
