The common problems in the process of raising pigs in the breeding households are mainly the lack of insulation measures, resulting in high mortality rate of suckling piglets, low weaning weight, serious diarrhea in suckling piglets, and stagnation of growth. These cultures hinder the development of the pig industry, so today’s small series Let’s talk about the solutions to common problems in raising pigs.
First, there is no insulation measures
1, the reason
(1) The temperature of suckling suckling pigs did not reach the temperature required for newborn piglets (28-32 degrees).
(2) In the autumn and winter seasons, the newborn piglets did not do or did not do the corresponding insulation measures in the evening, resulting in high mortality, multiple diarrhea and low weaning weight.
2, the solution
According to the weather and the breeding situation, the incubator is warmed up in time by the incubator, electric heating plate or ultraviolet lamp.
Second, the suckling piglets have severe diarrhea
1. Serious causes of diarrhea in suckling piglets
(1) The breeding environment is bad, the weather is abrupt, and it is not disinfected in time. The piglets have weak resistance.
(2) Sow milk has little or poor quality.
(3) The amount of iron supplementation and selenium supplementation is not timely or the amount of supplementation is small.
2, the solution
(1) Strengthen the management of sows in the perinatal period and do a good job of warming up.
(2) Strengthen the hygiene of the farmhouse and disinfect it regularly.
(3) 3 days of iron supplementation, 7 days of selenium supplementation, to ensure that the sow has sufficient and high quality breast milk.
Third, do not pay attention to feeding piglets
1, the reason
(1) The households do not understand the importance of feeding the piglets during lactation, and fail to replenish nutrients in time.
(2) The piglets do not feed, so that the gastrointestinal function is not fully exercised. After weaning, it does not adapt to the feed, and the body's resistance is reduced.
2, the solution
At 7 days of age, the feed will be supplemented with high-quality, fully digestible piglets, and the feed of each piglet before weaning will be no less than 400 grams.
Fourth, piglets weaning weight is small, uniformity is not good
1, the reason
(1) caused by weaning stress (emotional stress, environmental stress, nutritional stress).
(2) Lactating sows are not adequately nutritious.
(3) The piglets are not fed or fed too late, so that the gastrointestinal function is not fully exercised.
(4) Piglets have poor palatability.
2, the solution
(1) Use high quality sow breastfeeding and feed according to the procedure.
(2) At 7 days of age, the feed with high palatability and high digestibility was used to start feeding.
(3) Improve environmental conditions and ensure that the temperature is within the range of 24-26 degrees.
(4) The height of the drinker should be appropriate, and clean drinking water should be added in time.
5. Sows are not estrus, fake pregnancy, or repeated
1, no estrus reasons
Lack of VA, vE, trace element Zn and other feeds; feeding moldy feed; pigs are too fat and too thin; endometritis, vaginitis, ovarian atrophy, static, reproductive disorders infectious diseases.
2, not pregnant reasons
Fertilization disorders; lack of trace elements Zn, vitamin E; fertilized eggs, embryo death; hormone secretion disorders, ovarian cysts; feeding moldy feed; boar semen poor quality or lack of vitality; cervical mouth deformity, closure; Lan et al.
3, the cause of false pregnancy
(1) Reason
Early embryonic death; some diseases cause embryo death.
(2) Solution
The gilts must reach maturity and sexual maturity to participate in the breeding; meet the nutritional requirements and control the public opinion; the nutritional standard of the primiparous sows is higher than that of the sows; the aphrodisiac supplement; the western medicine treatment: the common application of western medicine: PG600, cloprostenene Alcohol, human chorionic gonadotropin, ovulation hormone, pregnant horse serum gonadotropin; drinking pregnant women with urine or intramuscular injection; feeding brown sugar water, green onions; using boar semen to stimulate sow estrus.
