Friends who often brush ** must have seen such a scene, in the farms of Europe and the United States and other countries, a hole was opened in the cattle bred. This phenomenon may not be strange to people who are used to seeing European and American farms, but for Chinese who meet it for the first time, this scene is extremely impactful and makes people feel deeply uncomfortable. So, why do Europe and the United States want to make holes in the body of cows?What is the purpose of this hole?Why is it rare for China to see holes in cows?
1. "Rumen fenestration"History and significance.
The history of this burrow in cattle dates back more than 100 years, beginning in 1928 when it was pioneered by the North Dakota Research Institute in the United States. It is often referred to as "rumen fenestration" and the technical term is fistula. Why do you want to make holes in the body of cows?This involves the structure of the cattle's stomach.
We know that cattle have four stomachs, of which the rumen is the key. It can store and decompose indigestible grass foods, but with the change of breeding patterns, European and American countries are gradually replacing forage with high-protein legume feed. This change places a burden on the cattle's stomach, leading to bloating and disease. To solve this problem,"Rumen fenestration"Surgery became a common practice.
2.The origin of the bloating problem.
Due to their large size, cattle need to eat a lot of indigestible grass foods every day. The other three "stomachs" are actually part of the esophagus, which has evolved into food reservoirs for cattle through special evolution. This system produces methane when it breaks down food, and methane has a greenhouse effect about 20 times greater than that of carbon dioxide, putting no small amount of pressure on the environment.
For thousands of years, cattle have mainly fed on grass, but with the rising demand for beef and milk in Europe and the United States, the high cost of forage and the long breeding cycle have led to the gradual replacement of forage with high-protein legume feed. This causes the cattle to suddenly change their diet and are unable to adapt, causing bloating problems.
3. "Rumen fenestration"Implementation and significance.
Rumen fenestration"The purpose of the surgery is to observe the breakdown of food in the rumen, to remove the gas produced in time, and to remove undigested food if needed. In this way, the farm is able to reduce costs and improve production efficiency.
However, the brutality of this surgery has sparked controversy. Before the operation, the cattle need to go on a hunger strike and receive local anesthesia, and then make an incision of 20-25 cm in the rumen position, and suture the ** and the rumen to form an opening. The cow suffers for a month until the wound is completely healed. Even after the wound has healed, the cylinders that grow on the cow can cause discomfort to the cow.
4.Why China is rare"Rumen fenestration"
Compared with European and American countries, China has a special affection for cattle. Cattle are an important labor force in traditional Chinese culture and are considered family members. In Chinese society, burrowing the body of a cow is considered cruel and unacceptable. This difference in emotion may be the reason for the rarity of Chinese farms"Rumen fenestration"One of the reasons.
5.Humanized breeding and cost considerations.
In the end, we need to think about a choice: which one would you choose, low-priced beef under relatively cruel farming, or humanely farmed but relatively high-quality beef?This is an issue that requires the common thinking of society.
Rumen fenestration"The implementation of the procedure has been widely controversial, involving ethical issues in the treatment of animal welfare and challenges faced by the farming industry. This practice is widely used in Europe and the United States, however, in some places such as China, the acceptance of this procedure is relatively low.
First of all,"Rumen fenestration"The purpose of the surgery is to cope with the problems faced by the farming industry, such as bloating and food indigestion in cattle. Countries in Europe and the United States have opted for this practical approach to reduce costs, increase production, and cater to the growing demand for meat and dairy products. However, this kind of surgery, performed for financial gain, has given rise to many ethical reflections.
From an animal welfare point of view,"Rumen fenestration"Surgery involves the infliction of pain on the animal. Before the operation, the cattle need to go on a hunger strike and receive a local anesthetic, and then make a larger incision in the body. This allows the cattle to endure not only the pain of the surgery itself, but also the discomfort of the recovery period within a month after the procedure. Although the veterinarian will house the cattle separately after the operation to prevent the wound infection caused by licking by other cows, this does not reduce the physical and psychological effects of the entire surgical process on the cattle.
Chinese farms are relatively rare"Rumen fenestration"The phenomenon of surgery may be related to the special affection that Chinese have for animals. In traditional Chinese culture, cattle are regarded as an important labor force and are closely related to the family. For Chinese, burrowing the cow's body can touch a cultural, emotional and ethical bottom line, so it is not easy to accept.
For the aquaculture industry,"Rumen fenestration"Surgery offers a convenient and economical solution, but it also calls for deep thinking about animal welfare and ethical issues. Globally, people's attitudes towards animals vary greatly, and this is not just a cultural difference, but also a clash of values.
When choosing a farming method, we need to strike a balance between economic efficiency and animal welfare. More humane and sustainable farming methods may be the way forward in the future to meet the demand for meat while minimizing harm to animals. It is also necessary to strengthen social education and supervision, guide people to pay more attention to animal welfare, and promote the aquaculture industry to achieve economic and moral win-win results.
