Chapter 1051 Humanoid Ultrasound Machine
The Han tribe should have been satisfied with this hybrid working breed, and the next step was to stabilize this breed. But at this time, the Han tribe obtained a third kind of cattle.
Speaking of this, we have to mention the grassland wolf tribe, which had fought with the Han tribe and later mixed with Maodun.
Although the name of the grassland wolf tribe contains the word "grassland", they are actually a nomadic tribe living on the coastal mountains in the southwest of the grassland. Although they also move around on the grassland, they spend most of their time in the mountains. Moreover, the cattle they raise are different from the common cattle on the grassland. This kind of cattle is called plateau cattle by the Han tribe.
This kind of plateau cattle is of medium size, with a pair of relatively large horns on its head, which grow upward and backward, but are not sharp. The average shoulder height is about 1.7 meters, which is slightly larger than the grassland cattle. The color of the fur is blue-gray, like stone, so it is also called big blue cattle and rock cattle.
And there is another striking feature in its body shape, that is, the shoulders are particularly high, which is obviously much higher than the grassland cattle and forest cattle, like a hunchback. Those who don't know it may think it is a dromedary camel. Of course, this is a bit exaggerated, but it does look very obvious.
The advantages of plateau cattle are also very prominent. Perhaps because of their poor living environment, these plateau cattle are particularly resistant to roughage. Not to mention shrubs and leaves, even thorns can be eaten. They are really not picky eaters. Basically, they eat whatever they can get as long as they can eat enough.
Moreover, these plateau cattle are strong, can carry and load, are good at climbing, and have amazing endurance. It can be said that the grassland wolf tribe can dominate the coastal plateau area in the southwest, largely because of these plateau cattle.
Luo Chong can say with certainty that in terms of the breed of working cattle, these plateau cattle can beat all other cattle in the world. Even the forest/grassland hybrid breed cultivated by the Han tribe with great effort cannot compare with this plateau cattle.
And it just so happened that in the Kaiyuan War a few years ago, the Han tribe defeated Maodun in one go, and the grassland wolves that mixed with Maodun were also killed by the Han tribe. So naturally, all the plateau cattle of the grassland wolves were also seized by the Han tribe.
With such good cattle, Luo Chong's first idea was of course to expand the scale of the plateau cattle breed and promote it in the Han tribe. Unfortunately, after these plateau cattle came to the Han tribe, they seemed to be a little uncomfortable with the local climate. Although breeders from all over the country took good care of them, many of them died of illness for some inexplicable reasons.
In the end, there was no other way. In order to preserve this excellent bloodline, there was only one way, that is, hybridization with local breeds.
With plateau cattle as the father and hybrid cattle bred by the Han tribe as the mother, the plateau cattle and grassland cattle were hybridized, and the hybrid offspring were hybridized with the previous hybrid cattle. After another three years of breeding,
they finally came up with an ultimate hybrid with half plateau cattle bloodline, one-third grassland cattle bloodline, and one-sixth forest cattle bloodline.
It is a medium to large size, 1.8 meters tall at the shoulder, hunchbacked, with dark blue fur or dark brown, and sharp horns that grow upward and backward.
This freak meets all the fantasies of the Han tribe about working cattle. It has strong explosive power and abnormal endurance. It can eat anything and is not picky about food. At the same time, it is very docile and likes to get close to humans.
The most important thing is that it meets the conditions of all terrains and all climates. Whether it is roaming in Heyuan County in the north, the island climate of Qiongzhou, or the inland plains and mountains of Hanyang County, this kind of cattle can adapt well. Basically, as long as it is properly cared for, it will never get sick or have acclimatization.
It also fully embodies the four words "hard work and endurance". It is simply a model among working livestock, like a leader. Whether it is plowing or pulling a cart, it has always been hardworking and never complained, and never complained even if the food is worse.
However, although this cow is good, there is still the same problem. The breeding time is too short, and the bloodline has not yet stabilized. It may suddenly go crazy and give you a freak, or there will be a "reversion" phenomenon, that is, the recessive gene becomes a dominant gene, or it is inherited from the first generation, and the offspring born suddenly become the appearance of its "grandfather" or "great-grandfather".
In biology, this situation is called breed degeneration.
There is no good way to deal with this situation. We can only select excellent individuals from this newly cultivated population and carry out long-term and stable internal reproduction. After the precipitation of time, this breed can be completely stabilized.
In fact, the principle of breed breeding is very simple, just like a palette. What elements you need, just add them in and blend them. The difficulty lies in the fact that this process is very time-consuming. It may take several years to breed a breed, and it may even take more than ten years to stabilize it. The process is extremely boring.
At present, Luo Chong asked Sinong Temple to breed beef cattle. The process is the same, but unlike working cattle, beef cattle pursue high meat production, tolerance to roughage, easy to raise, and fast growth.
For such a requirement, it is definitely right to choose forest cattle as the main body. The forest cattle have an average shoulder height of two meters. In the same period of time, they grow the largest, which means more beef.
Moreover, among the three native breeds and two hybrid breeds of the Han tribe, forest cattle have the strongest explosive power and the most developed muscles. More muscles mean that the whole body is full of tendon meat. In terms of meat quality, it is also the best among several cattle.
Therefore, when it was proposed to breed beef cattle this time, Sinong Temple had already made a goal based on experience. The new breed of beef cattle must have at least half of the bloodline of forest cattle, because forest cattle themselves are large in size, have excellent meat quality, and are not picky eaters. As long as they are slightly supplemented with the docile character of plateau cattle, they can be trained into a good beef cattle breed.
Moreover, in the beef cattle breeding plan, the genes of grassland cattle will basically not be directly added. With the results of the previous hybridization, Sinong Temple directly used high-quality pure-blooded forest cattle as the sire, and the dam was a batch of hybrid cattle bred with plateau cattle as the sire and grassland cattle as the dam.
The purpose of doing this is to ensure that the new beef cattle are docile and obedient, while not being overly dwarfed by the genes of grassland cattle, which would cause the bred beef cattle to shrink in size. In this regard, the genes of the paternal line are still very strong, and no one can deny it.
"At present, our farm has done the first breeding work. We have selected two purebred forest cattle as breeding cattle for the paternal line, and 80 'high/grass hybrid cattle' for the maternal line. Now 67 of them can be confirmed to be pregnant. We are also preparing to let the remaining 13 complete the pregnancy within this month. In addition, we have prepared a family tree for each cow, including their unborn calves, to ensure that we can trace their origins and even find out who their ancestors are."
The person in charge of the farm quickly introduced the current situation.
Luo Chong was a little surprised after hearing this, and immediately asked, "Eighty cows, only two breeding bulls, are these bulls enough?"
He said this, but secretly complained in his heart, one male with forty females, don't let his waist break, right? If not, give them some supplements? !
However, when he heard Luo Chong's question, the person in charge laughed, and a breeder next to him was a herdsman transferred from Kaiyuan County. After hearing Luo Chong's question, he immediately answered.
"Leader, you don't know, this kind of cattle and stallions can mate many times a day during the estrus period, but in order to ensure quality, the number of times should be controlled. Generally, a maximum of two times a day can ensure that the cows are effectively pregnant. If they are not pregnant within a month, they can wait for the second round to make up for it. The remaining thirteen cows that have not conceived are the ones that did not successfully conceive in the first round."
"Oh?!"
Luo Chong was even more amazed when he heard this, thinking that they are indeed worthy of being breeding cattle, and they are really "too capable", but then he took another look at the cows grazing in the central pasture, which looked no different from ordinary cows, and immediately asked curiously.
"Then how do you determine which of these cows are pregnant and which are not?"
Hearing this question, the herdsman breeder immediately proudly recounted his "experience".
"Well, how to judge whether a cow is pregnant can be determined by a few points. First of all, the cow's eyes. The white part of the eyeball of a pregnant cow will have two or three blood vessels protruding and turn purple-red, which looks like a person who is sleep deprived. The accuracy rate of this feature is relatively high.
"Another way is to observe the daily changes of the cows. Pregnant cows will eat more and gain weight faster. This is to store more nutrients.
"Another thing is that pregnant cows often have feces balls hanging behind their buttocks, which means they can't poop cleanly."
The herdsman paused and finally concluded, "The above few points can determine whether a cow is pregnant, but they are not necessarily accurate. The most accurate way to test is to touch it with your hands."
"Touch it with your hands?!" Luo Chong was even more surprised, "How do you touch it? Can you feel whether a cow is pregnant through the belly? If the pregnancy is a few months, the belly will be bigger and you can feel it, but how do you touch it when you are just pregnant?"
"This, this."
The herdsman hesitated when he said this, and glanced at the person in charge of the farm next to him, not knowing whether he should say it.
"Don't look at me, what's there to hesitate about, just say it if the leader asks." The person in charge immediately expressed his opinion.
"Yes, Chief, for this, we usually put our hands into the intestines and feel directly to the uterus in the belly that carries the calf, and feel the uterus and follicles through the intestines in the belly.
"An experienced person can determine whether a cow is pregnant by just reaching out, but inexperienced people had better not do it lightly. First, it is easy to be kicked by the cow, and second, it is easy to cause miscarriage in the cow and death of the calf." The herdsman boy answered immediately.
"Intestines? Reach in through the anus on the buttocks (anti-harmony)?" Luo Chong was shocked when he heard it, with an incredible look.
The herdsman boy nodded when he heard it, and looked at Luo Chong honestly, with an expression that said, "Yes, it's just what you guessed," and then added a sentence without thinking.
"Yes, it's the same for mares. "
Luo Chong was speechless.
Wow!
This is really a rare skill!
To be honest, there are no veterinary B-ultrasound machines in this era. Mastering the skill of livestock pregnancy examination is indeed a rare talent. This is the truth.
Luo Chong couldn't help but look up to this guy, then patted him on the shoulder and encouraged, "Work hard in Sinong Temple in the future, and it's best to carry forward your skill. You are very good, I am optimistic about you!"
The herdsman boy was immediately delighted and excited. He froze on the spot for a while, not knowing how to react.
Luo Chong did not stay any longer, turned around and walked somewhere else, while the person in charge of the farm patted the man on the shoulder and encouraged him in the same way.
"Did you hear that? Work hard. The leader values you very much. You will be a formal member of Sinong Temple in the future. It is estimated that you will have an official position in the future. "After saying that, he followed Luo Chong.
Then the few people went to the pigsty and visited the piglets that had become 'eunuchs'.
It has to be said that pigs do grow fast after castration. The person in charge of the farm listened to Luo Chong very much and even did a comparative experiment. In front of them were two adjacent pig pens, one of which was not castrated, and the other was castrated. They were born at the same time and ate the same feed, but the castrated pigs were obviously larger than the non-castrated ones. As
the saying goes, there is no harm without comparison. Now that the two types are put together, even Luo Chong, who has never raised pigs himself, can see the difference between the two sides at a glance.
"Not bad, it seems that these castrated piglets are growing well! By the way, have you learned the castration technique? If this technology can be successful, you should train a group of people as soon as possible and then send them to the Animal Husbandry Bureaus in various places. You can charge the people to castrate piglets. On the one hand, it is for promotion, and on the other hand, it is for making money. "
Hearing Luo Chong's question, the person in charge immediately said, "Well, I have learned it, but I don't have many opportunities to practice. If I practice with a live pig, I might kill it. It seems that I can only hope for more help from the medical school. "
Luo Chong was speechless when he heard this. He was thinking about whether to set up a veterinary branch under the medical school and develop a systematic teaching model for the skills of pregnancy examination and castration.
After visiting the farm and finding that all the projects were going well, Luo Chong finally felt relieved. However, the weather became more and more gloomy. On the second day, it finally rained.
This was the first rain this summer. It was not very heavy, but the weather suddenly became hot after the rain. The third day was a sunny day. The sun was scorching in the sky. Although it was very hot, the moisture in the corn field evaporated quickly. The land in the field soon hardened again, and the harvesters that had been thirsty for a long time could finally get off the field.
I have something to do these days. I will resume updating from today. I will make up for it tomorrow if I have time.
