The invention provides a sow high-yield technology which is applied to the technical field of pig cultivation. According to the technical scheme, sow oestrus and much
ovulation are promoted, fetal death is reduced,
breastfeeding milk quality is increased, and meanwhile sow
health protection is paid attention. The sow high-yield technology is characterized by comprising an oestrus and much
ovulation technology, a
mating and much nidation technology, a
pregnancy and
miscarriage proof technology, a delivery and stillbirth-free technology, a
breastfeeding and
lactation disorder proof technology and a sow
drug medicine protection technology. The technical scheme in cultivation is given out systematically, the cultivation is programmed and digital, the sow
pregnancy rate and the farrowing number are increased, the sow service life is prolonged, and production costs are reduced.
