Causes and preventive measures of piglet weaning syndrome
Piglet weaning syndrome is a common disease in young piglets after weaning, which manifests as loss of appetite, diarrhea, dyspnea and other discomforts. Piglets need breastfeeding after birth, but at about 21 to 28 days, they need to be slowly weaned and start eating independently. This process is very important for the growth and development of piglets, but it is also easy to cause a series of health problems. So, what are the causes and prevention measures of piglet weaning syndrome?
When are piglets weaned? What is the cause of weaning syndrome?
Piglets are generally weaned at 3-4 weeks of age. At this time, piglets and sows should be fed separately, and the feed of piglets is changed from full milk diet to dry feed. Weaned piglets are in a clear growth and development stage, but their digestive function and immunity are not strong enough. With changes in environment and feed, piglets can produce strong stress.
What are the symptoms of piglet weaning syndrome?
When piglets show loss of appetite, digestive dysfunction, diarrhea, slow growth, etc. , which is the so-called "early weaning syndrome of piglets", also called "weaning stress syndrome of piglets".
How to prevent and treat weaning syndrome of piglets?
How to feed weaned piglets reasonably? Can weaning stress syndrome of piglets be effectively prevented?
1. Keep the environment of piglets unchanged
When weaning, change the sows to feed, keep the piglets in the original pens, let them live in a familiar environment, and keep the feeders and feeds relatively stable. After the spirit, appetite and feces of the weaned piglets are normal, the feed, feeding mechanism and mixed pens will be gradually changed.
2. Ensure the temperature of the pig house and avoid severe cold stress
Piglets have poor adaptability to low temperatures. If weaned in the low temperature season, the severe cold stress of piglets will be aggravated. At this time, antifreeze and heat preservation measures should be taken in particular. Piglets should be raised in closed pig pens. The suitable temperature for piglets aged 15 to 30 days is 22 to 25℃. When weaning, the working temperature can be appropriately increased to 25 to 30℃. At the same time, lay grass or sacks on the pig pen road surface. Electric heating plates, infrared bulbs, general bulbs, etc. Insulation can be carried out according to actual conditions. At the same time, the wind tunnel should be blocked to avoid thieves and keep the room dry. Since the working temperature is lower than the most suitable temperature for piglets, it is easy to cause diseases such as pulmonary diarrhea, fever, and fever.
3. Piglets should do a good job of protection
In the late pregnancy of sows, mami iron (an organic compound iron supplement for sows and piglets) should be added to the sow feed to avoid iron deficiency anemia after weaning of piglets; because piglets are weak, they are prone to diarrhea within a week after weaning, especially for piglets weaned in the early stage, diarrhea is more serious. At this time, we should pay attention to changing grass frequently, cleaning frequently, and cleaning the pig pen regularly. In addition, we should pay attention to keeping the pig pen dry. Cold temperatures and harsh environments can easily aggravate diarrhea in piglets.
4. Train piglets to defecate as soon as possible
If piglets defecate everywhere in the pig pen, it will cause the pig pen environment to be damp, cold, and polluted, which is easy to spread diseases and is not conducive to the growth of piglets. Therefore, we should pay attention to training piglets to defecate as designated. This work must be done at weaning, otherwise as the piglets age, training will become more and more difficult. When cleaning the pigpen, you can leave some feces in the designated area, or moisten the area with water, and the piglets will gradually develop the habit of designated defecation.
5. Prepare for a rainy day and add probiotics in advance to regulate the stomach
Add teaching trough feed in advance, which can be added when the piglets are 7-10 days old, so that the piglets' stomachs can adapt to the digestion of feed, and add baby music containing enzyme preparations to regulate the intestinal flora environment of piglets. Breeding is to nourish the stomach, and piglets with intestinal flora have strong resistance.
6. Add organic trace element iron supplements to the feed
Add 500 grams/ton of organic iron supplements to the compound feed for suckling piglets, which directly avoids the stress response caused by iron needles in piglets, and can also prevent the spread of diseases to a certain extent, with good intestinal absorption, diarrhea, low food intake, slow growth and other problems are solved.
