Problems solved by technology

The probability of intractable constipation in sows before and after farrowing is relatively high, accompanied by anorexia in sows, prolonged labor, dystocia, poor milk quality, diarrhea in piglets, etc., causing great economic losses to pig farms
[0004] At present, there are a large number of drugs for the treatment of constipation in the market, some drugs are not suitable for sows during pregnancy, before and after delivery, and the effect of treating intractable constipation in sows is not good

Description

technical field [0001] The invention relates to a feed additive for sows, in particular to a feed additive for sows before and after delivery and a preparation method thereof. Background technique [0002] Obstinate constipation in sows is a relatively intractable disease in the current pig production process, especially for sows before and after delivery, which will be very affected after constipation. Sick pigs show loss of appetite or refusal to eat, lack of energy, reluctance to move, sometimes lying down in the pen, and the feces balls are as small as abacus beads. [0003] The cause of the disease is mostly due to the exuberant virtual fire and slow gastrointestinal motility caused by endocrine disorders in sows. Of course, high temperature stress, lack of exercise, and insufficient drinking water caused by various reasons are also important causes of constipation in sows. In addition, drugs are also the cause of constipation in sows. Currently, there are many dise...
