1, control mycotoxin
The harm of mycotoxin to sows: pregnant sows show abortion, stillbirth, fetal mummy and abnormal postpartum estrus; Eight legs and mortality of newborn piglets increased. Sow: The vulva of sow is red and swollen, and the volume and weight of uterus are increased, which is characterized by estrus or labor. Lactating sow: it is characterized by gradually refusing to eat, continuing estrus or prolonging estrus cycle, which affects the survival rate of lactating piglets. Sows will have rectum and vaginal prolapse. Therefore, in pig farms that only use premix or concentrated feed, mirex (1000 kg/kg mirex mixed feed) must be added to the feed for a long time.
2. Viral diseases such as porcine pseudorabies, porcine parvovirus disease, porcine Japanese encephalitis, classical swine fever and blue ear disease are also important reasons for sow reproductive disorders. Viral diseases focus on immunity. In the first three days and the last three days of immunization, polysaccharide toxins and vitamins (Vitopo) must be added to the feed to improve the immune effect.
3. Control of postpartum inflammation in sows:
Cefotiofur sodium powder injection should be injected three days after delivery; In 1 ton feed, two kilograms of pesticidal powder, 1 kg of Mokra and 1 1,000 grams of vitamins must be added three days before delivery and three days after delivery.
4. Measures to prevent sow estrus and repeated infertility:
(1) Routine adjustment: exercise, feed, light, boar stimulation (or boar semen and urine).
(2) Nutrition regulation: sodium ascorbate, vitamin E, vitamins and polysaccharide toxins are added to the feed for a long time.
(3) Hormone regulation:
① 200-300 ug of sodium cloprostenol+1000 IU of maternal serum (PMSG), and estrus was observed 7 days after injection.
② If there is no estrus, an aphrodisiac midwifery needle or sodium cloprostenol 1 time can be injected 65438-/0/2 days after injection.
5. Health care plan for sows and finishing pigs in summer and autumn:
Mix 1kg Qingwen Baidu powder, 1kg Kelaifuning, 250g polysaccharide toxin and 500g vitamin and stir for one week. It can prevent diseases such as high fever, streptococcus and eperythrozoonosis.
