7. Maintenance of Reproductive Function After Delivery
(1) Prevention and Treatment of Postpartum Lochia and Endometritis
After farrowing, intramuscular injection of 20-40 units of oxytocin (long-acting antibiotic) in sows, or intramuscular injection of 0.1-0.2 mg of cloprostenol (long-acting antibiotic), can be administered, and uterine infusion of one dose of Gongyankang can be given to prevent secondary infection of endometritis in sows.
(2) Methods of Promoting Lactation
The production and release of breast milk are jointly regulated by four hormones. Lactationinducing agents, composed of estrogen and progesterone, regulate these processes at two stages, with very noticeable clinical effects.
(3) Treatment of Endometritis
After treating the uterus using the methods described above, to help the uterus recover quickly and enable normal estrus and mating, an additional 1000 units of human chorionic gonadotropin (HCG) and 0.1-0.2 mg of Cloprostenol or 20-40 units of Oxytocin can be administered.
Generally, sows recover after a single treatment, can return to estrus and mate in a timely manner, and show good conception and farrowing outcomes.
8. Postpartum Estrus Induction
1. On the day of weaning for multiparous sows, inject 1000 units of PMSG intramuscularly, plus 0.1-0.2 mg of Cloprostenol. Five days before breeding, inject 5 ml of VADE, and at the time of breeding, intramuscularly inject 25 µg of Ovulation Inducing Hormone No. 3 (LHRH-A3).
9. Prenatal and Postnatal Medication and Health Care
Inject long-acting oxytetracycline, amoxicillin, or doxycycline 7 days before delivery. Inject 5 ml of VADE 5 days before delivery. After delivery, oxytocin, dinoprostone sodium, and Gongyankang can be used for treatment.
10. Induced and Spontaneous Abortion
For pregnant sows that exceed the expected delivery date and still do not give birth, inject 0.2 mg of cloprostenol sodium (PG) intramuscularly; delivery can occur the next day. For abnormal pregnant sows (with stillbirths, weak fetuses, or mismatched pregnancies), inject 0.2 mg of cloprostenol sodium (PG) intramuscularly once daily for 2-3 consecutive days.
First, use estradiol benzoate (E2) to facilitate the opening of the birth canal, then combine with oxytocin (OT) to promote uterine contractions.
11. Boar Health Care
Regularly strengthen the exercise of the boar's cardiac muscle and hind limb strength, along with supplementation of related nutrients.
Enhance the inspection of boar sperm quality, preferably using a digital biological microscope connected to a computer for systematic management.
For boars with low libido, low semen volume, or poor sperm motility, intramuscular injection of human chorionic gonadotropin (HCG) 5000 IU can be administered.
For boars with insufficient sperm count, treatment can be done using Luteinizing Hormone-Releasing Hormone 3 (LHRH-A3), Follicle-Stimulating Hormone (FSH), or Pregnant Mare Serum Gonadotropin (PMSG).
LHRH-A3: Once a day, 25 micrograms per day, with a total dose not exceeding 75 micrograms.
FSH: Once a day, 100 IU each time, for 2-3 consecutive days.
PMSG: 1000-2000 IU, single dose.
12. Benefits of Using VADE
1. Administering 5 ml to pigs every season throughout the year can improve their stress resistance and, more importantly, enhance sperm vitality and mounting ability.
2. Administering 5 days before farrowing can prevent white muscle disease in piglets and postpartum paralysis, and ensure the sow produces higher-quality and more abundant milk. The long-lasting effect can continue until weaning, allowing the sow to return to estrus on time.
3. Administering 2 ml to piglets 2 days after birth has been shown in control groups to increase profit by 15-20 yuan per pig by the time of market, and it is especially recommended for weak piglets.
