Four points for attention in the management of parturition of sows

Whether the management of parturition of sows is good or not determines whether the sows can operate normally after delivery. Many postpartum problems in sows, such as hysteritis, mastitis, non-milk syndrome and piglet diarrhea, are directly related to prenatal management.

  

I. preparation of the delivery room

  

The delivery room is very important to both sows and piglets, and if the delivery room is messy, cold and humid, or both, it is likely to cause adverse consequences of disease in the pig farm. Cleanliness and dryness are necessary conditions for a good environment in the delivery room.

1. Soak the birth bed and the ground for 0.5-6 hours, then clean up the loose faeces and feed residues with shovels and other tools, and then fully rinse the fence and the ground.

  

2. Clean the fence and equipment of the system, pay attention to clean the sink and material trough and their surroundings; rinse the visible dust; do not directly flush the unisolated delivery house with a high-pressure water gun, which will have a negative impact on sows and piglets. Can be washed with a hose.

  

3. For the disinfection of the delivery room, we must maintain a sufficient concentration of disinfectant without spraying.

  

4. The pig house must be completely dry before the sow is transferred to the delivery room. If the pigsty is not dry, the water will evaporate from the ground, which will make the ground and the birth bed cold.

  

5. Check each water fountain to see if the flow rate of water can reach 4 liters per minute. Insufficient drinking water will lead to a decrease in feed intake of sows, especially in summer. The recommended amount of water to drink during lactation is 35-50 liters per day.

  

6. Check whether the insulation lamp can be used, and whether the ground temperature can reach 34 ℃-35 ℃ after turning on the insulation lamp.

  

2. Move the sow to the delivery room 5-7 days in advance

  

[advantages]:

  

1. Piggery and railings can be fully dried after cleaning.

  

2. Sow feed can be adjusted 2-3 days before delivery to avoid problems during delivery.

  

3. Sows have plenty of time to adapt to the new environment.

  

4. Sows do not begin to give birth in the pregnancy house.

  

Third, the feed reduction and feeding of prenatal sows should be divided into different conditions.

  

(1) according to the body condition and breast development of sows

  

The main results are as follows: 1. Sows with good body condition and good breast development: the amount of feed is gradually reduced from 3 to 5 days before pregnancy to 1 / 2 or 1 / 3 at the level of late pregnancy, so as to prevent excessive milk secretion from causing mastitis or piglets diarrhea caused by excessive milk secretion.

2. Sows: no diet should be reduced.

  

3. Sows with insufficient breast expansion during prenatal days should be fed with some protein-rich feed, such as fish meal.

  

(2) according to the parity of sows

  

1. First-and second-born sows: first-and second-born sows are small, have a low feed intake, and seem to have little feed and are full. Therefore, the first and second sows try to control the material before birth, otherwise there will be no food for a few days after delivery. More importantly, it may be due to prenatal feed control, resulting in too high emulsion concentration, causing nutritional diarrhea in piglets.

  

2, 3 sows after birth: big, just raising such a big body needs to consume a lot of material, so she almost never has enough to eat, and is always in the control of food. So there is no need to reduce the amount of food before delivery, and of course you can't let it eat to the point where there is a lot left in the trough.

  

Fourth, effective health conditioning should be carried out according to the current state of sows, such as constipation, deficiency of qi and blood, lack of productivity, postpartum fatigue, etc.

  

[methods]:

  

1. Mixed feeding of lactating sows: from 15 days before delivery to weaning estrus, 1000 jin of feed was added with 1000 grams of Shuangbuyisan + 1000 grams of Yimuyuan + 500g of Butaaneng powder.

2. Intramuscular injection: after the sow breaks the amniotic fluid or gives birth to a piglet: intramuscular injection, 15-20 ml.

  

[effect]:

  

1. Replenish qi and blood internally, recuperate the five internal organs, and replenish physical strength externally to enhance physical strength.

  

2. Effectively shorten the process of labor and reduce stillbirth

  

3. Improve the quality and quantity of milk, improve the vitality and evenness of newborn piglets.

  

4. Shorten the estrus interval days of sows after weaning and improve the service life of sows.

  

5. Promote the recovery of postpartum appetite.
