Delivery room environment Sows should be prepared for the delivery room 7 days to 10 days before the sow’s arrival. The delivery room requires drying (relative humidity 60% - 75%) and insulation (room temperature 15°C - 20°C), adequate light, fresh air. If the humidity is high, the air can be exhausted; if it is cold, it can be windproof and warm. Essential supplies and inspections Incubators (lights, umbrellas), water basins, buckets, sterile towels (hand wipers for the confinement personnel, and two for piglets), pliers, scissors, cotton balls, syringes, 5% iodine, high manganese Potassium acid solution (used to sterilize and cut umbilical cord), disinfectant, iodine, antibiotics, oxytocin, vaccines, postpartum health care products, vaseline (for dystocia midwifery), weighing scales, ear clamps, and childbirth record cards, etc. Get ready in advance. Check whether there is water leakage and pressure condition in the drinking fountain; check if there is any breakage in the floor of the delivery room for the leakage of manure; check whether the insulation equipment can work normally. Find problems and fix them in time. Accurately estimate the due date The due date should be calculated based on the parity and breeding records of the sow bedside card. It is also possible to predict the expected date of birth for gestating gilts based on breeding records. The method is mainly calculated using the “three, three, three†method, ie 3 months (303 = 90 days) plus 3 weeks (73 = 21 days) plus Last 3 days. Observe signs of childbirth Pre-production sows can undergo many changes, and production can be guided by these changes. In general, the sows will experience some physiological and behavioral reactions before their delivery. First look at the shape: from the side, the abdomen is large and vertical, the breasts are shiny, the base of the nipple is thick and short, and the tip is expanded; from the front, the walk is twisting and careful, and the last pair of nipples is closely behind the hind legs and is " The figure eight hangs between the hind legs, and most sows squeezably see a small amount of milk. Usually, colostrum begins to secrete several hours before delivery, some postpartum secretion, and very few of these changes are obvious, so we must make a comprehensive judgment. Secondly, look at the genital area of ​​the sow: the vulva is swollen and swollen, the sides of the tail roots begin to sag, and the sow shows restlessness. This phenomenon usually occurs after 6 hours to 12 hours. The third is to look at the prenatal symptoms: extreme anxiety, standing and lying, breasts bulging, chaos around, nipple out of water, straight limbs, orderly, intensified urgency, shortness of breath, genital water. Sow delivery care Combine with daily management, check the breeding log, and make timely preparations for prenatal care. Usually about 7 days before childbirth, sows can be allowed to enter the farrowing room to allow the sow to familiarize herself with the production environment. After a few days of adaptation, the sow does not affect her mood and lactation during production. Before entering the delivery room, the sows must use cold water in the summer, cool water in the winter, autumn and spring, and sterilize the body with a pungent iodine preparation such as chlorothalonil and wipe the body surface with a towel. After the moisture is removed, the dirt on the surface of the pig, especially the breast and the pus, is removed, and the conditional pig farm can shower the sow. Sows are usually in the morning fasting, the sire cubs slowly rushed to the bed before the production, so that the pig itself to the active delivery bed, must not be impatient. After the sow enters the delivery room, it is necessary to add feed as early as possible to adapt to the delivery room environment as soon as possible. At the same time pay attention to the sows entering the delivery room, according to the order of the expected date of production for management.
