Umbilical cord weaning
The umbilical cord of each piglet should be cut at about 2cm, the broken end should be sterilized with tincture of iodine, and the rest of the umbilical cord will fall off naturally when it recovers.
Tail breaking
Tail breaking reduces the incidence of tail biting during the nursery and growth stages. Use sterilized pliers to break the tail 2-3 cm from the root of the tail (the upper edge of the scrotum for boars and the upper edge of the scrotal gate for sows) and sterilize the tail with tincture of iodine.
Cut the canine teeth
Cutting off the canine teeth can prevent the piglets from hurting the sow's nipple or hurting the piglets in the same litter when they are scrambling, and the canine teeth are usually cut off with sterilized tooth-cutting pliers. Care should be taken when cutting the teeth, the teeth should be cut as close as possible to the surface of the tooth bed, do not hurt the tooth bed, once the tooth bed is damaged, not only preventing the piglets from suckling, but also the injured tooth bed will become a potential infection point.
Heat preservation and anti-pressure
Newborn piglets at 0 to 3 days of age, the optimal growth temperature of 29 ℃ ~ 35 ℃, 4 to 7 days of age for 25 ℃ ~ 29 ℃, 8 to 14 days of age for 22 ℃ ~ 25 ℃, 15 to 21 days of age for 20 ℃ ~ 22 ℃.
Prevent sows from stepping on piglets. Newborn piglets can be used within one week of birth to protect the baby box will be mother, piglets separated (every 2 ~ 3 hours to let the sow nursing 1 time), or in the sow house against the wall with a log or iron pipe in the wall and the ground 25 cm away from the set of guardrail, or in the sow house with a wooden board or brick, build a closed all around, one side of the door (for piglets to enter and exit) of the protection of the child, so as to avoid sows step on the pressure of the piglets.
Eat enough colostrum
Newborn piglets must suck colostrum to get immunity. When breastfeeding colostrum, let the piglets choose the sow's nipple by themselves, and then adjusted according to the weight size, physical strength, once found that there are piglets competing for the same nipple, it is necessary to adjust in a timely manner, and it is best to fix the weak piglets in the front of the sow, the middle of the udder breastfeeding, large, powerful piglets fixed in the middle of the sow, the rear of the udder breastfeeding, so as to make the entire litter of piglets to develop neatly. If a few weak piglets do not suck milk enough, supplemental feeding can be done to improve the survival rate of the whole litter. When the sows die or have no milk after birth and the number of piglets produced exceeds the number of effective nipples, it is necessary to foster the piglets to other sows for nursing. When fostering, we should make full use of the pig's sensitive sense of smell, and apply the milk of the nurse (urine is not advocated) on the whole body of the piglets before fostering and nesting, and mix the group at night to make the piglets adapt to the fostering, and then pay attention to the observation, to prevent the sows from refusing to breastfeed or biting the fostered piglets.
Iron supplement
Newborn piglets have only a small amount of iron reserves in their bodies, usually 1-2 ml of soluble iron complex injection is given intramuscularly in the neck within 3 days after birth, but iron supplementation immediately at birth will cause serious stress to piglets.
Disease prevention and treatment
Before eating colostrum, can be inoculated with swine fever free and weak vaccine once according to the routine dose, commonly known as over-immunization, and then let the piglets eat milk freely after 2 hours. In addition, sows can be given hygromycin to prevent red and yellow diarrhea in piglets. The pen should be cleaned daily to keep the house clean and dry and provide a hygienic, quiet and fresh air living environment for the piglets, which should be carefully observed every day and found to have dysentery and abnormalities, which should be diagnosed and treated in time.
Six factors affecting the survival rate of piglets：
Group health degree (epidemic prevention);
Sow and piglet environment (temperature, humidity, air quality, density) piglet 1st day after birth (receiving care, colostrum, heat preservation, fostering);
Timely diagnosis and treatment of sick sows and piglets (visual inspection-recording);
Correct tusk clipping/tail breaking/deconditioning handling procedures (equipment intact, sterilized);
Weak piglet management (less attention, spend more limited energy on 2 days before birth).
