Generally speaking, when it comes to raising pigs in spring, most friends may know to "protect the liver" and "repel insects", but many pig farmers may not know why and how to protect the liver and repel insects in spring. Today, I will answer this question for you.
Why do pigs need to protect their liver?
It is considered that in clinical practice, we often encounter sows with increased tears in their eyes, rusty spots on their backs, rough hair and emaciation, bleeding spots on their backs, decreased reproductive function of sows, increased number of weak offspring and stillbirths, no estrus after weaning, and a high proportion of estrus.
The number of tears in the eyes of suckling pigs and fattening pigs increased, and even the eyelids were red, swollen and emaciated in severe cases, and the feed-meat ratio increased and the growth rate decreased.
These problems are generally called sub-health symptoms of pigs.
The most common cause of sub-health in pigs is impaired liver function and excessive endotoxin in pigs. The common toxins in pigs are mycotoxins, disease factors, drug toxins and body toxins.
1, mycotoxin: Although the fungicide will be added to the feed, it is impossible for the fungicide to completely absorb or decompose the mycotoxin in the feed, and it will still enter the pigs, causing damage to the pig liver, but it is more or less.
2. Pathogenic factors: common swine fever, pseudorabies, etc. It will cause pathogenic damage to the liver of pigs.
3, drug toxins: pigs can not do without diseases, diseases must be prevented or treated. Antibiotics are the most commonly used in the prevention and treatment of diseases, and the harm of antibiotics to pig liver is a * * * knowledge.
In addition, antipyretic and analgesic drugs, hormone drugs and anti-inflammatory drugs will all cause damage to the liver of pigs.
4. Toxins in the body: mainly substances such as endotoxin produced by bacteria living in pigs.
As can be seen from the above situation, no matter what kind of breeding method is adopted, toxins always exist in pigs. What we can do is to reduce the sources of toxins, such as using fungicides, reducing the frequency and dosage of antibiotics, and preventing diseases; On the other hand, it enhances the detoxification function of the liver.
A two-pronged approach can control the toxins in pigs at a relatively safe level, so it is very important to protect the liver during the feeding of pigs.
Why should we protect the liver during the Spring Festival?
"Six Sections of Zangxiang in Su Literary Theory" said: "The liver is the foundation of the extreme, where the soul does not live. Its glory lies in claw nails, and its nourishing tissue lies in tendons, which can nourish qi and blood. Its taste is sour, its color is pale blue, and it is a little yang in the yang, which is connected with spring air.
Because the physiological characteristics of the liver in spring are relatively rapid, this opportunity to recuperate the liver can get twice the result with half the effort and prevent diseases, so it is called "nourishing the liver in spring".
It is suggested that liver-protecting and kidney-protecting drugs, such as Yinchenhao powder and Longdan Xiegan powder, should be added to pig feed or drinking water in spring for 14 days, with an interval of 14 days, and then for 14 days.
Why do you want to repel insects in spring?
Parasite is one of the diseases that have an important impact on the health and production performance of pigs in the process of raising pigs.
First of all, parasites can damage the skin and mucosa of pigs, thus creating opportunities for the invasion of other pathogens.
Secondly, parasites will absorb a lot of nutrients from the host, which will affect the development of pigs and feed conversion rate, leading to the decline of growth rate of commercial pigs, malnutrition and sub-health of sows.
Many parasites feed on the host's blood, which is one of the reasons why pigs have rough fur, rough skin and emaciation.
In spring, everything recovers, and parasites wake up from the sleeping winter and start to multiply and invade the pigs, which is harmful to the pigs. Therefore, it is necessary to repel insects in spring.
How to expel insects correctly?
Growing and finishing pigs-two-stage Sanqi method: a, 10 weeks old, add insect repellent to feed and mix well, continue to use for 7 days, stop using for 7 days, and then use for 7 days.
B. When 15 weeks old, add insect repellent into the feed and stir it evenly, continue to use it for 7 days, stop using it for 7 days, and then use it for 7 days.
Breeding pig-Four Seasons and Sanqi method: In the middle month of each season, add insect repellent into the feed and stir it evenly, and use it continuously for 7 days, stop using it for 7 days and then use it for 7 days.
