Main goals of pig farm production management:

1), The pig only produces a header / sow / year: high yield, high generation, dead and mummy 伊 伊

2), high-yield index: short breastfeeding (weak milk to breeding, low return rate 】
3), low mortality: lactation, during the postpartum period, and the mortality rate during the bumper period are low.
4), feed remuneration: high

5), daily gain: fast

(pay attention to 20 key points of red)

1, prenatal immunity

The injection of E. colonic seedlings were performed 3 weeks and 6 weeks before childbirth, and it is recommended to use Haibole’s seven-valent seedlings – Xi Easheng, 14 days before the birth (I Vioxin 0.4 mg / kg body weight, orally; 0.25 mg / kg body weight, intramuscular injection), starting to change tantammtrifice in 10 days;

2 The sky will rinse the room, then dry for 1 day, according to the expected date of birth, the sow in the first 3-4 days ago is fully brushing and disinfecting, and the movement of pigs is light, can’t whipping the pig;

After born 1 hour, use disinfection lines, then leave 8-10 cm to cut, and disinfect it with iodine wine (more bleeding in birth, immediately ligation and stop blood); if the pig farm is using a desiccant (when the pig It can be used for the amazo-drying meshydrate, and the umbilical cord can be used to automatically fall off after the umbilical cord;

If you are born, you should wipe the mucus in the mouth, then manually breathe

The pig produced should not be separated from the sow, and the pig’s sucking milk can stimulate the secretion of the mother pig oxytocin. When the pig’s amniotic fluid is baked, it can feed the milk; It is best to hang a light bulb behind the sow;
Pay attention to the birth of the last three pigs to monitor, prevent suffocation, each pig, 6-7 pigs must strengthen the monitoring Because most dead tolls occur in the final three pigs;

6, rational use of oxytocin

u Normal production interval is 15-20 minutes, but the first The spacing of the new piglets may be 30-40 minutes. If it is not normal (using the production of more than 30 minutes above), it must perform the sub-homodes in front of the use of oxytocin. Help each time, prevent the infection infection, preferably use a dedicated long arm glove, if there is no need to completely clean the hand, apply a certain lubricant;

U oxytocin each time The dose of use is 5-10UI;

U if there is no effect half an hour;

Guaranteed that each piglet eats raw milk (can be born in batches, ie 4 to 5 small pigs after eating early milk) Get up and tagged, then let the new piglet eat raw milk), if some sows have a lot of milk, it can be collected in a sterile manner within 6 hours after childbirth, and then sealed freezing. More than 4 weeks, the next time it is preheated to 37 ° C to feed 20 ml / head to the larvae;

The quality of the breastfeeding sow will directly affect the water supply of the mother pig, with a variety of foreign varieties Take the pig, the lactating pig is required to high protein high energy, and pay attention to the quality of the protein (nutritional requirements: digestive energy 3.35 mega / kg; 17.5% of crude protein, 1.0% lysine); 1 can be fed daily 4 Taking the feeding capacity of the mother pig (goal: according to the recommended feed nutrition, the whole lactation of the sow is 110-120 kg / 21 days)

8, postpartum examination
The phenomenon of sows measured by the sow and the phenomenon of vaginal dew, which can be considered 3 days after 3 days after each maternal,

If the sow occurs Breast inflammation should immediately conduct antibiotics + heating analgesics + oxytocin for 3-5 days of continuous treatment; if it is a breast trauma, the cleaning and disinfection of wounds is carried out, and the antibiotic treatment is carried out;

9 Temperature management

Shot of the sow: The ideal temperature is 20-21 ° C within 5 days of postpartum, after 17-18 ° C; the temperature requirements of piglets: 34 ° C in the first week, second Zhou 31 ° C, last 28 ° C, the fourth week 26 ° C;

The temperature of the sow will affect its appetite, and the temperature of the small environment will directly affect the survival rate of piglets, to meet small The temperature of the pig is generally accommodated in an infrared lamp to increase the incubator. In order to increase the effect of the incubator, it can be placed on the incubator or wooden board;
