As we all know: the sow is the core of the pig farm and the source of production. The health of the sow directly affects the overall health of the pig farm and directly affects the farming benefits of the pig farm.
It's hard to raise pigs, it's even harder to raise sows!
The root causes of pig raising difficulties are as follows:
1. Insufficient qi and blood, stagnation of qi and blood
Second, the labor process is too long
Third, toxin accumulation
Root 1: Insufficient qi and blood, stagnation of qi and blood (performance and harm)
1. The skin is pale, frizzy and frizzy.
2. The birth weight is small, the vitality is poor, the size is uneven, and the number of litters is small.
The piglet's birth weight and vitality depend entirely on the quantity and quality of qi and blood obtained from the mother through the umbilical cord. Especially one month before giving birth is the fastest period of fetal weight gain. The normal or negative sow's qi and blood directly affect the birth weight and vitality of piglets.
3, the lack of milk, piglets weaned light.
Milk is the only source of food for piglets immediately after birth. Blood is homologous, and qi stagnation results in insufficient milk, which makes it difficult for piglets to eat, and their growth and development are naturally severely affected.
After the sow is delivered, the blood is strong and smooth, the milk secretion is sufficient, the maternal antibody is high, the piglets are full, the piglets are strong and grow fast, the weaning weight is high, and the survival rate is also high.
4. The labor process is too long and difficult to deliver.
If the sow is deficient in both blood and blood, it is susceptible to contractions and weakness, the uterus is dry, and the delivery time is prolonged. Lead to a series of problems such as stillbirth, weak births, and postpartum non-eating.
5, weaning without estrus or weaning estrus interval is long.
Chinese veterinary medicine believes that the main reason for sows not to be in estrus after delivery is that the sows lose both qi and blood after delivery.
Root cause two: The labor process is too long (main performance and harm)
1. The number of fake dead pigs and weak piglets increased significantly, the survival rate of piglets decreased, the incidence was high, and the weight of weaning litter decreased.
2, stillbirth (white stillbirth) increased significantly.
3. The sow's physical energy consumption is too large, excessive fatigue, postpartum anorexia and no eating.
4, lead to the slow discharge of lochia, lochia inexhaustible, affect the recovery of the uterine wall, and eventually form inflammation causing endometritis.
5, postpartum little milk, no milk, poor quality sow milk, piglets diarrhea, piglets grow slowly, uneven size.
6. The estrus is slow after weaning, and there are more sows not in estrus or return to estrus.
7. Increase the labor intensity of the midwife.
Root cause 3: accumulation of toxins (main manifestations and harms)
1, obvious tear spots, dirty cheeks
2, old bleeding points or bleeding in the back or body
3. Sub-health, immune suppression, immune failure, high incidence
What should I do if I encounter the above problems?
To solve sub-health such as sore tears, eye feces, and back dirty, nutritional management should start with nutrition management. Stopping abuse of antibiotics is the first step. Prevent mold and mold. Pay attention to the nutritional balance of feed. Establish the awareness of regular conditioning according to the course of treatment, severe pigs need 2-3 times to be completely resolved.
