Why is the sow always dystocia? the root of the disease is here!

The dystocia of sows is also common in the process of practical production, because they do not know the technical knowledge of raising sows, the economic loss is often quite large, the light piglets are stillborn, and the heavy ones both mother and son die. Well, some farmers who have a little understanding of one or two can only adopt the way of artificial midwifery. due to the lack of professional midwifery guidance, it will often cause birth canal scratches and endometritis, which will directly lead to the inability of sows to use, and only choose to be eliminated. There is only a cheap treatment for a sow who dies in childbirth, and there is also a few hundred yuan in money, but it is only a drop in the bucket compared to the cost of breeding a pig.

Generally speaking, miscarriages of sows mostly occur in the first parturition sows, and some of them are dystocia in parturient sows. The dystocia of parturient sows is mostly caused by feeding and management, not to mention the dystocia of parturient sows today. In the following time, I am analyzing in detail the reasons for the dystocia of parturient sows. The book is back to the original, why is it the first child? This has to talk about the causes of dystocia, generally nothing more than these reasons, one is that the individual sow is too small, the reproductive tract is not well developed or narrow, the second is that the individual of piglets is too large, and the third is that the buttocks of some breeds of sows are too plump. The fourth is the early time of breeding, and so on. Here a few details should be analyzed one by one, because these details are the root of the disease!

First of all, the most sensitive part of the "buttocks". Generally speaking, whether pig breeders keep their own breeds or go to other places for introduction, the first thing they look at is the size of the sow. Where does the figure look?. Look at "ass", as long as it is "big ass" is a good pig! I'd like to say something here, do you think it's a beauty pageant? You think "giant buttocks" is Kardashian? In fact, there is nothing wrong with the body shape, blindly pay attention to the body shape, but the risk exists. In fact, the buttocks are too plump, when giving birth, it will cause the pubic symphysis not to open and the birth canal narrow, which will directly lead to the dystocia of sows. Choose sow is not "cat bean", beautiful body may not be able to make money for you, everything should be considered!

The second is the timing of mating sows, that is, how old and when sows can be mated. If the sows are in estrus prematurely, but the sows have not yet reached physical maturity and some reproductive organs are not fully developed, the root of the scourge of breeding sows has been buried ever since. The correct indicator is that the sow reaches an effective age of 8 months, the weight is maintained at about 120 kg, and the estrus is in estrus for 3 times in mating, that is, these simple points for attention can not be done well by some pig farmers, and we must follow the scientific method as a guide to do a good job in key breeding links.

Another is that sow dystocia is directly related to the amount of exercise of sows. Now, due to the limitation of the site, sows are basically raised by sow limit bars. The local problem is solved, and the problem arises at the beginning. The breeding, breeding and pregnancy of the back sow are basically spent in the limit bar, and the sow is not easy to endure until it is about to go to the birth bed, so it is impossible to imagine that it is still on the "one-mu and three-point land". After sitting on the "month", it goes back to the limit bar over and over again. Over and over again, even people also point to "hold back madness", where to exercise, where to get free! Well, in some conditional pig farms, sows are raised in pens, which will greatly reduce the risk of dystocia in sows. In fact, this is also a welfare that sows should have.

Here once again remind the majority of farmers, some factors can not be avoided, in view of the above situations, we should be prepared to prevent dystocia, prepare for what? Is "Chloroprostol", not "oxytocin", because it has the role of preventing dystocia, should be injected on the prenatal day.
