How to judge whether there are piglets when pigs give birth?

1, see the external performance of sows.

Because the sow will be very uncomfortable when giving birth, as long as there are piglets not born, the symptoms of hard work, convulsions and trembling will not disappear. If the sow suddenly quietens down, it means that the sow has finished giving birth. If the sow gives birth, there is no stimulation to the uterus, and the sow's production reaction naturally disappears.

2. Look at the strength of sow responsibility.

If there is no effort to prove that the delivery has been completed, if there is still a slight effort, it means that there are still fragments of fetal membranes or the fetus is not completely discharged.

3. Count umbilical cord heads

Look for the umbilical cord head along the thick blood vessels. One umbilical cord head of a piglet corresponds to one placenta. Under special circumstances, the large placenta has more than one umbilical cord head. At this time, how many umbilical cord heads correspond to how many pigs!

4. Look at your stomach

The abdomen of the unborn sow bulges, while the uterus of the parturient sow collapses, and the skin on the chest belt is quite loose and naturally droops.

Step 5 step on the sow's uterus

The method of counting umbilical cord heads can only guarantee 99% accuracy. Under special circumstances, there may be 1-2 piglets in the uterus of sows. Because of sow productivity or other reasons, the output was delayed, and most of them were wrapped by fetal membranes, which were not found in time, and piglets died of suffocation.

In order to avoid the above situation, you can step on the sow's uterus a little hard. If the sow's belly bulges badly, it proves that there are piglets in the uterus, which is the maternal reaction of the sow's childbirth hormone to stimulate the brain and protect the piglets in the stomach. Otherwise, it has already been divided.

6. Look at the color of the placenta.

The dark placenta is very thin, and the sow has not finished eating. Light afterbirth and air bubbles. Many fetal membranes are thick, and sows have already given birth.

Matters needing attention in sow delivery bed

Sow maternity beds are all made of high-quality original engineering polypropylene, which has reliable quality, stable performance and is not easy to age. The surface of all sow bed castings is smooth, and there are no defects such as porosity, sand inclusion and looseness. All welded parts are welded firmly, which can be used for the cultivation of weaned piglets, automatic drinking and free feeding.

Metal and plastic rain-leaking floors are generally used in breeding pens, and the structure of pigsty is divided into two types: grid and solid. The structural form of pigsty listed in this standard is fence type. High-culture maternity bed is a kind of single column, which is the place where sows give birth and nurse. In the middle of the delivery fence is a sow limiting frame, which is the place where sows give birth and piglets breastfeed, and on both sides are places where piglets eat, drink, keep warm and move.

The sow spacing frame is generally made of round steel pipe and aluminum alloy, with a leaky floor behind it to remove feces and dirt, and piglet activity bars on both sides to isolate piglets.
