How does the survival rate of newborn piglets increase? The survival rate of newborn piglets has a lot to do with sows, do you know? So sow farmers have a lot of the following precautions in the process of breeding sows! Different breeds of pigs have different gestation periods, which are generally normal between 112 and 116 days, so there are many small ways to promote the survival rate of piglets at this stage!
1. Careful observation of the sow before delivery
1.1 The vulva is more swollen 4 days before the sow is delivered.
1.2 2 days before the birth, the sow's breasts will accelerate the development and can obviously see the swelling.
1.3 In the 24 hours before the birth, the sow will be anxious and uneasy, and there will be an attempt to build a nest. For those who cannot build a nest, they will bite the pig house equipment and use the front hoof to scratch the floor.
1.4 The nipple can be squeezed out of milk 6 hours before delivery.
1.5 In the 30 minutes before the birth, the sow gradually quieted and lying on the side, began to suffer from pain, and when the amniotic fluid flowed out, the work can begin.
2. Childbirth process
The sow's farrowing process is usually 4 to 5 hours, with an interval of 20 minutes, while the first 4 piglets have a slightly longer interval. If the number of litters is small, the longer the interval and the shorter.
2.1 Carefully check if the sow has finished producing piglets, and one placenta corresponds to a small pig.
2.2 In the process of littering, if there is insufficient anger, you can use 20 units/head for the sow in small doses. At the same time, you can also force the sow's nipple to promote the sow's birth.
2.3 If the piglet is found to be not fully produced, and the sow has no littering action, the sow can be properly moved in the hallway so that the sow will produce the piglet smoothly.
2.4 If the above methods are not feasible, the sows can be assisted.
In the case that the sow does not completely produce the piglets, it is necessary to carry out artificial midwifery on the sows in time. In doing so, it can reduce the consumption of sows and greatly increase the survival rate of piglets. The following work must be done before the manual main midwifery.
3. Midwifery process
3.1 Thoroughly clean the dirt behind the sow before the start of the midwifery.
3.2 Put on gloves during midwifery, apply a sufficient amount of gel on your hands, remember not to touch anything with gel-coated gloves.
3.3 Slowly extend the arm into the sow's uterus. The piglet in the positive fetal position can grasp the neck, eye socket or mouth. For the reverse, use the index finger and middle finger to clamp the knee joint of one leg, and pull the piglet slowly and horizontally.
After the completion of the 3.4 multi-solet midwifery work, the sows should take appropriate rest.
3.5 Postpartum sows are more or less infected, so the sow must be anti-inflammatory. Anti-inflammatory drugs can be selected by injecting ceftiofur sodium with Houttuynia cordata. The best anti-inflammatory effect can be achieved by injecting once a day for 3 days.
3.6 Finally, the majority of farmers are reminded to recommend the elimination of sows with congenital pelvic stenosis. In the midwifery, try to use the person with the midwifery experience to complete the midwifery.
It is necessary to know the time during which the sows are bred and breed, and the fertilized eggs are probably bred in the sows. This is the best time to improve the survival rate of piglets. Therefore, we must master this period, especially the sow farmers!
A tracheostomy tube consists of three parts: outer tube with flange, inner cannula, and an obturator. The outer cannula is the outer tube that holds the tracheostomy open. A neck plate extends from the sides of the outer tube and has holes to attach cloth ties or velcro strap around the neck. The inner cannula fits inside the outer cannula. It has a lock to keep it from being coughed out, and it is removed for cleaning. The obturator is used to insert a tracheostomy tube. It fits inside the tube to provide a smooth surface that guides the tracheostomy tube when it is being inserted.
