in the pig breeding process, is the key stage of the whole feeding pigs in the production process, especially in newborn pigs, such as do not take active protection, mortality can be as high as 50% or more, if can through the dangerous period, it can greatly improve the survival rate of pigs, so as to improve the production efficiency of pig. strengthen management and improve the resistance of pigs
(1) maternity ward should do well in environmental sanitation and pay attention to disinfection. before entering the delivery room delivery room to sow their clean, disinfect the floor, walls and fences with disinfectant related. the walls, doors and windows damaged should be repaired, prevent thieves, maintain good temperature and humidity. the ground should be smooth, and check the incubator, heat lamp, water faucet, feeder and other functions are normal.
(2) sows were attenuated before birth". in late pregnancy 85 days before delivery, 5 days ~7 days, with sensitive drugs do "sow attenuated", mainly for prrs pmws infection, reproductive disorder, swine fever pseudorabies, mycoplasma infection through mother to child transmission or concurrent pathogen "early treatment", reduced morbidity, and at the end of pregnancy to anti stress, to prevent abortion. recommendation: 30 days prior to the delivery of astragalus for immune peptide 10% amoxicillin powder, consecutive 15 days; at the same time in the parturition after a week before the first rice (oxytetracycline injection hin 0.2 ml / kg w), the control of sow triad (mastitis metritis agalactia syndrome - -).
sows in 40 days of delivery to the vaccine work such as escherichia coli vaccine, pseudorabies, recommended immunization before and after using toxin injection against 1 ~2 times, so as to improve immunity, relieve immune stress.
(3) pigs drinking water should be sufficient. in 3 day old pigs at ~5 days of age to add clean water, as in every 1 kilograms of water add salt or glucose infusion 20 kg of sodium bicarbonate, 2 grams, 0.06 grams of vitamin.
(4) pay attention to the production work, zizhu was born in time after insulation pressure, cord, cut tooth tail, eat colostrum, fixed nipple number. in the new born pig before feeding with bacteria to kill the poisonous power (according to the instructions to use) or saline wash the nipple, and breast milk after milking let zizhu suck, make pigs quickly gained the maternal antibody.
(5) 1 day old, 7 day old, 21 day old pigs after birth, available first rice (oxytetracycline) hin three needle care, 1 days injection hin meters in the first 7 days injection 0.5 ml, 0.6 ml, 2 ml injection at 21 days of age. can effectively prevent zizhu diarrhea and early respiratory syndrome, significantly improve the survival rate of pigs.
(6) the difference of iron supplementation. pigs 3 days after birth intramuscular injection 1 ml blood; 3 ~ 5 days, intramuscular injection of vidin colloidal calcium 0.5 ml, 1 times before weaning again. this can prevent zizhu diarrhea, white muscle disease, nutritional anemia, rickets.
strengthen the insulation and anti pressure work
newborn pigs die because the laying pressure of sows kills about 20% of non infectious deaths and increases the temperature, which can be reduced by the addition of energy.
let pigs eat colostrum as soon as possible.
increase sow nutrition
in addition to normal feeding, the nutrition supply should be strengthened in the late pregnancy, and short-term feeding should be carried out. as per head per day increased more than 1 kg of feed mixed concentrate or add animal fat or vegetable oil in the diet on the basis of the original (for dietary 5%~6%), to help improve the difference of birth weight and survival rate; fat content of supplemental fat also improve the colostrum and milk. dietary supplementation with vitamin c in sows before 1 weeks, can greatly reduce the mortality and zizhu umbilical hemorrhage in pigs.
