Some of the thinking about animal intestinal health

According to the American association of swine veterinarians, with 310 new cases of NAHLN report this week, the United States pig epidemic diarrhea cases, so far the total number of cases of the disease has reached 3873, 25 states confirm the outbreak. Now pig epidemic diarrhea in many pig farms have already popular trend, is the biggest consumption aquaculture feed, however, the biggest organ of nutrient absorption and the most important is the intestinal immune organs. Health is the result of a balanced nutrition, nutrition absorb depend on the intestinal digestive function is normal, should start from the root solve health problems. Modern biomedical research results also show that almost all of the health, longevity and intestinal problems. Medical experts pointed out that 90% of the human body and intestinal disease, a large number of toxin fermentation cause chemical changes, the harmful material into various tissues and organs, especially the so-called human liver - the largest chemical factory, make its metabolism, sterilization, detoxification, into the blood, and other functions, can be directly cause person in pathology, indirect can accelerate the aging of human body.

Intestinal problems is very important

100% of nutrients through the intestinal absorption, so there is no good intestinal nutrient absorption, or to find themselves; At the same time, 99% of the toxins from the intestinal absorption into the body, when 0.1% of harmful bacteria, viruses, investigators looking into the human body, the body will face disease. 84% of malnutrition caused by intestinal animals; More than 130 kinds of vitamins necessary for human in the food does not exist, only depends on synthesis of intestinal beneficial bacteria, so it is very important to intestinal problems.

Colonize the intestinal tract (colon), a large number of flora in the gut flora of life with 1 -- 3 kg, the total weight per gram of about 1 trillion live bacteria of intestinal contents. These living bacterium by bacillus, bifidobacterium, clostridium, wei rong aureus, escherichia coli, lactobacillus, enterococcus and so on dozens of species of 400 ~ 500 strains. They in maintaining the body's biological, chemical, immune barriers, as well as to the airframe nutrition, health, defending against pathogenic microorganism, immune, anti-tumor and so on, play an important physiological role. Japan's light content once said: "is the source of the disease, intestinal disease from intestinal health of the body health." Now people pursuit of high-speed growth and ignored the most important animal immune, healthy intestinal environment is the foundation of the animal immune and growth.

The root of the intestinal health is the right body to build and establish animals grow environment. Pig will determine the health of the living environment, also determine his gut health. Alleged illness, we make the pig live in a healthy environment outside still need to make sure that the pig body health. This requires comprehensive feed nutrition science. One of the young animals feed ratio, because of the digestive tract of piglets nutrition metabolic physiology has its inherent characteristics:

1. The piglet gastrointestinal only accounts for 3% ~ 6% of body weight, but the nutrition metabolism accounted for about 40% ~ 60% of the animal feed nutrient;

2. The consumption of oxygen makes up about 20% ~ 35% of the body's total consumption;

3. Energy consumption accounts for about 25% of the body's consumption;

4. Protein turnover accounted for about 20% ~ 35% of the whole body turnover;

5. The intestinal epithelial cell average updated once every 3 ~ 5 days;

So weaning piglets, gastrointestinal metabolic strength is very big, inadequate nutrient intake can cause intestinal development, is the core of weaned piglets gastrointestinal injury. Such cases, feed utilization rate is very poor, loss is invisible, many farmers can't see. According to statistics, China's pig 18 to 21 days of the sow lactation quantity reaches its peak, every little pigs eat every day 1 to 1.5 kg of milk, converted to dry matter intake is: 180 ~ 300 g; Three days after weaning piglets feed intake of 50 ~ 100 g, weaning feed intake below 50 g on the day.

When the intestinal nutrient deficiencies of intestinal basic physiological metabolic processes will be crimped, characterized by the secretion of digestive enzymes; The absorption of cells weakened; Immune barrier blocked; Inflammatory response. Bacteria, toxins, and difficult to digest food particles stay in the health of the gut, will be gradually eliminate, within the unhealthy gut bacteria, toxins and food particles can through holes into the blood, the influence is healthy.

Know the intestinal immune

Understand the intestinal immune must understand the structure of intestinal. Intestinal wall is divided into four layers, mucous membrane, submucosa, muscularis and serosa layer. Mucous layer and intestinal mucosal epithelial cell layer constitutes the important line of defense. In terms of self-healing capability, plays an important role in the gut. In fact the body's ability to heal itself is very powerful, the German national research institutions in 2001 in a research note said: "if you can treat disease of matter called" medicine ", is can produce more than ten thousand kinds of medicine of human body oneself! And that more than ten thousand kinds of medicine has more than seventy percent in the intestines."

In fact, the body's immune cells are nearly 80% in the gut. Systemic lymph node distribution in intestine (60% ~ 70%, antibodies produced by the intestinal mucosa than fluids, the intestinal immune system produced by the immune globulin IgA accounted for 60% of the body produces the immune globulin. Intestinal bacteria when many would have to stimulate lymphocyte immune globulin, will adhere to the virus.

The intestinal immune function is being built?

SIgA can reduce pathogenic bacteria attached on the surface of the mucous membrane, and bacterial toxins and agglutination, thereby limiting pathogenic bacteria breeding. Production has a lot of phenomena such as sow constipation, anorexia, split hooves production stillbirth are the result of the toxins, pigs feeding meat contrast, slow growth is largely related to intestinal flora.

Rich in lymphatic tissues in the intestinal mucosa, intestinal by former backward, most especially the ileum and colon. Intestinal and respiratory, under stress condition, such as the weather changes, vaccination and turn group, etc., can lead to mucous membrane barrier change: epithelial cell surface bacterial flora changes. Under normal circumstances there are many beneficial bacteria on the intestinal protection, but in case of stress, acid molecular layer is missing, intestinal epithelial cells on the adhesion strength of the beneficial bacteria is abate, bacterium, virus translocations. When the intestinal unhealthy, immune cells and immune globulin to reduce or weakened, immunity will decline.

The intestinal health care train of thought

5 years ago we pig industry focus on respiratory problems, respiratory and digestive tract virus now is China unicom, the stress in our pig there anytime and anywhere, we should be how to think?

The traditional thinking is, when the pig diarrhea and respiratory problems, we tend to use antibiotic, the result in time and kill harmful bacteria to kill a lot of beneficial bacteria. Now a lot of high level of pig farm is no longer use of antibiotics, but there are still quite a number of pig can only use drugs to maintain the development of the farm. Now we use antibiotics at the expense of the pig intestinal health for pigs is not death, we had a lot of no treatment value of pig production, found that the intestinal flora has been destroyed, such pigs farmers invisible loss is bigger. So now we care to do corresponding adjustment on thinking.
