What are the three common positioning methods for sow embroidery?

1. You can use the middle finger of your left hand to hold the sow’s left hip tubercle, your thumb to press the abdominal wall on the same side, and press hard in the vertical direction of the left hip tubercle held by your middle finger. The left thumb pressing the abdominal wall and the hip tubercle supported by the middle finger must be close to each other, and the line connecting the thumb and middle finger must be perpendicular to the ground. Generally, the pressure point at the end of the left thumb is the site where surgery can be performed, and the incision distance is generally on the left Side nipple 2-3cm.

2. Sows must be fasting before castration. If it is summer, in order to prevent pig epierythrozoonosis, the castration equipment must be soaked and disinfected in alcohol. After the castration is completed, the piglet's hind legs can be lifted up and down to reset its intestines, so that there will be no problem of intestinal intrusion.

3. In the first few days after castration, you must feed less and more frequently, and do not feed it too full. If a pig does not like to eat, be sure to lift its hind legs to see if the castration port on the abdomen is swollen. If swelling occurs, most of the time it is a leaky intestine. In this case, surgery must be performed to return the intestines to the abdomen.

Sow farrowing management

1. Pay attention to the sow’s farrowing time. If the farrowing interval is within 20 minutes, it is normal. If the time interval between delivery is more than 30 minutes, the labor process exceeds 2 hours, and the symptoms of dystocia are manifested, then you should consider using oxytocin to assist the delivery. The specific dosage is determined according to the instructions, or artificial delivery can be used.

2. In order to prevent infection in the uterus and birth canal after sows give birth, antibacterial and anti-inflammatory drugs are perfused or injected; the afterbirth of sows needs to be taken away after giving birth, otherwise the sows will cause intestinal diseases if they accidentally eat it. After the sow gives birth, the piglets must eat colostrum in time. The sow's colostrum is rich in immunoglobulins, which can effectively improve the survival rate of the piglets and enhance the piglets' disease resistance.
