I don’t know if you’ve ever seen a scene like this. A cow’s stomach is perforated, and people can put their hands in it directly. They don’t know what they’re digging. Many people wonder why they want to make a hole in the cow? There are also some reports that human beings directly smash the testicles of cattle to castrate them. Perhaps a large number of people are angry. Why do they do this? Why are human beings so cruel that cattle don’t hurt? So, is it the “heartlessness” of human beings that will do these things. Today, we’re going to talk about the things that happened to the cows who were “opened windows” and hammered testicles.
Different use of cattle in China and the United States
In China, the use of cattle is different in each period. In fact, the domestication of “cattle” by Chinese people began 6000 years ago. Among nomads, domestication of cattle in grassland areas may be more remote. Cattle were used for sacrifice in ancient times. At that time, people used cattle as the top grade of sacrifice. After that, cattle were used as a means of transportation, “cattle cart” and farming tools, so there was a nose piercing technique, which was to make cattle servants do high-intensity work. In the spring and Autumn period and the Warring States period, there was a record of “cattle ploughing with iron plow”. Milk and its products have always been the staple food of nomads. By the northern and Southern Dynasties, milk and its products had become a delicacy in the rural areas of northern China. As for the meat of cattle, China had been far less concerned about the food of cattle than pigs.
In the United States, on the contrary, Americans have always regarded beef as a staple food, which is an indispensable dish on every table. In China, beef is bought for 30-60 yuan per kilogram, while in the United States, the lowest price for beef is only 1.6 US dollars per kilogram, which shows that Americans take beef as their main meal, like Chinese grain. Because Americans take beef as their staple food, the beef industry in the United States has been developing very fast.
Rumen fenestration in cattle
Let’s first briefly introduce the “fenestration” operation of cattle. Before fenestration, the cattle should be forbidden to drink water for 24 hours, disinfected in the middle of the left side of the cattle, and cut after anesthesia. After cutting the middle of the left rib, the rumen should be cut again, and then the cut rumen should be sutured with the skin. The operation is over. To put it bluntly, the rumen is connected with the skin, and a flange barrel is installed between the rumen and the skin. So why do we need to open a window? Why only do the rumen fenestration surgery?
As we all know, cattle are ruminants, cattle have four stomach: rumen, reticulum, omasum, true stomach. Among them, the rumen of cattle is the largest of the four, and the rumen is also the first stomach of all ruminants. As the most important digestive organ, the food of cattle accumulates in the rumen of cattle, which is a common digestive disease in cattle. The scientific name is rumen accumulation of cattle, also known as acute rumen dilatation. The rumen fenestration of cattle is also developed for this disease.
For example, when cows have problems such as discomfort and flatulence after eating feed, we can directly take samples from the flange tube, which can easily find out where the problems of cows are. Compared with the past, we need to detect the blood or feces of cows, which is undoubtedly a lot more convenient, so that’s why we need to open the rumen of cows Window surgery, then we see before, the human hand in the cow’s body can be understood.
It is obvious that there is something wrong with the body of the cow when people take out the sample in the cow’s stomach. It is not that people are “heartless” but that they are helping the cow solve the problem. But would it hurt to do that on a cow? Obviously, the answer is yes. Although anesthesia will be used during the operation, the wound is so big, and a flange tube will be installed on the cow’s body. No matter how well it is installed, there must be great discomfort in doing these things in the body, and there will be risks of lung and heart diseases if the flange tube is installed.
As far as animals are concerned, no animal is willing to do so. Obviously, this practice has both advantages and disadvantages. For cattle, it may be more painful. But when the cow has digestive system problems, you can directly see the digestion process and eating situation of the cow, which not only makes great convenience for the doctor’s work, but also solves the digestive problem of the cow. Cows that have undergone rumen fenestration live longer and produce better milk than other cows, according to farm experts.
Castration of cattle
Castration of cattle means directly smashing the testicles of cattle. It sounds simple, violent and inhumane, but it will not infect the reproductive organs of cattle. It is often used by the people. Although the cow is extremely painful, but this method is beneficial to the cow, the recovery after operation is also very fast, and will not affect the ability to use.
There is another way, but it is not easy to operate. In the experiment of castrating cattle, the left lateral lying beef cattle are often used. The first necessary operation is to disinfect the surgical instruments and tools. The operator holds the knife in his right hand and holds the scrotum tightly in his left hand. After cutting the scrotum in his right hand, he has to squeeze out the testis, separate the inherent tunica vaginalis with bare hands, then slowly pull the testis to expose the spermatic cord, and separate the tunica vaginalis ligament from the spermatic cord to the epididymis The tail is cut off, and then the tunica vaginalis ligament is separated to the detail of spermatic cord along the spermatic cord. The left hand holds this place and begins to knot the tunica vaginalis ligament around the spermatic cord with the right hand. Generally, two or three knots are made continuously towards the testis, and then check whether it is firmly tied. The spermatic cord is cut off outside the last knot, and the testis of cattle is removed.
The management after the operation is also very important. The cattle must be kept in the cowshed, and the faeces of the cattle must be removed in time to prevent infection. At the same time, high-quality feed must be prepared for feeding. Neither the wind and the sun, nor excessive drinking and eating are allowed, so as to avoid gastrointestinal damage. After more than ten days, the cattle can be freely raised. Some people wonder why we should castrate cattle. In fact, there are many advantages.
For humans, castrated cattle will reduce the flow of nutrition and energy to the reproductive system, so that cattle can grow and develop rapidly. In this way, the meat quality of castrated cattle is much higher than that of non castrated cattle. The taste will be very good, and the economy of the ranch will be greatly improved. Moreover, the castrated cattle are docile and easy to manage, which reduces the aggression to human beings, and will not be in estrus There will be a fight with other bulls for a mate. There is also castrated cattle will not retain their own genes, so there will be great room for improvement in the cultivation of high-quality cattle.
Although, as mentioned above, rumen fenestration and hammering castration of cattle have more advantages than disadvantages, from a certain point of view, these are wishful thinking behaviors of human beings. We all think that doing so will make cattle “better”. However, we have no idea whether the good pursued by an ordinary animal is to produce more nutritious milk and better beef.
In fact, for Xiaobian, my impression of cattle still stays in the story of “cows blocking cars” I saw when I was a child
In the extreme water shortage of the west, an old cow suddenly ran away from the reins and ran to the side of the road where the water truck must pass. When the water truck passed by, the old cow stood in front of the water truck. No matter how its owner beat it, it did not move and just howled at the water truck.
The man in the car stopped the owner of Lao Niu. At the risk of being punished, he put a bucket of water in front of Lao Niu. He thought Lao Niu would drink the water in front of him immediately, but after Lao Niu barked, several hungry calves came from a distance. Lao Niu watched the calf drink the water and then turned away.
