Feeding and management of parturient sows

Doing a good job can promote the natural birth of sows and improve the survival rate of piglets. Perinatal period refers to the period from 108 days after mating to giving birth, when the parturient sows are transferred to the litter house. In order to make parturient sows adapt to the new environment as soon as possible, feed normally and give birth safely and smoothly, the whole body of sows should be cleaned and disinfected. Prenatal feeding technique

Add or subtract feed. 10-15 days before delivery, sows were gradually fed with lactation feed to prevent indigestion and piglet dysentery caused by sudden postpartum feeding. If the fat condition of sows is good and the breasts are dilated obviously, the feed should be gradually reduced 7 days before parturition, and half of the diet should be subtracted from 1 to 2 days before parturition. Stop feeding when you find the symptoms of labor, and only feed bean cake and bran soup. If the fat condition of sows is poor and their breasts are withered, not only should they not be reduced, but also soybean cakes and other protein feed should be added to prevent sows from having no milk after delivery and exercise in the right amount.

Get rid of external parasites. Sows like to lie down a few days before delivery, do not like too much exercise, and should create a quieter and comfortable environment for sows. If lice or scabies are found in sows, deworming drugs such as ivermectin should be used to eliminate them so as not to pass them on to piglets after delivery.

Breeders should have more contact with sows and touch the sows with hands or wipe the sows with soft brushes when feeding or cleaning the barn, so that they can form a conditioned reflex that is not afraid of people, so as to prepare for people to come into contact with sows during delivery. It is best to put something such as mat grass in the enclosure to facilitate the sow to pick up the grass and the breeders to observe the delivery time of the sow.

Prenatal observation

When the sow was 7 days before parturition, the development of mammary gland was enriched gradually, and there was a clear boundary between the base of breast and abdominal wall, which changed more and more obviously with the approach of parturition. The activity of sows decreased significantly in the later stage of pregnancy, and their temperament became docile and liked to lie down, but the sows were abnormal 2 days before delivery, generally showing restlessness, abnormal eating, and defensive reactions. when strangers approach, they will open their mouths and attack. As the parturition time approaches, the frequency of sow defecation will increase.

Prenatal sow bathing

Before the sow enters the delivery room, the birth bed and incubator should be thoroughly cleaned and disinfected, the sow's dirt should be washed clean, then disinfected once with medicine solution, and the pig should be disinfected with the bed again on the second day after giving birth, so as to reduce the pathogens brought from the breeding house as much as possible.

Delivery and appliances

Sows should prepare utensils and articles needed for delivery before delivery, such as iodine tincture for disinfection, alcohol, boxes for piglets, flashlights and lights for lighting, electric air or stove for heating, infrared lights and other heating equipment, wiping cloth for delivery, ear clamps for earring, pliers for tooth-cutting and scales for weighing piglets, etc.

Nursing care of parturient sows

After delivery, the reproductive tract of sows is still open, the physical strength is weak, the resistance is decreased, and it is easy to be infected by pathogenic microorganisms, so necessary health care measures should be taken.

Feeding method of postpartum sows

The feed intake of sows after parturition has a direct impact on the survival rate, weaning weight and estrus of sows after weaning. Generally speaking, according to sows' appetite, fat and parity, wet mixing can increase feeding times in summer, increase feed intake during lactation and reduce weight loss during lactation. During the lactation period, the feed intake was controlled at more than 6 kg, and the sows after delivery were fed with 200 grams of brown sugar twice a day for 10 days, which was beneficial to the recovery of sows' physical strength and the elimination of lochia.
