Segregated early weaning method of piglet

Abstract

The invention discloses a method for segregated early weaning of piglets, which comprises the steps of medicine adding, segregation, early transfer and the feeding of early weaning by piglet feed, wherein the medicine adding is performed before and after the delivery of a sow, the advanced medicine adding is used to kill off microorganisms which is expected to be killed, and the medicine adding is also performed from the birth of a suckling piglet to the weaning; the segregation adopts that the parturient sow is transferred into a clean farrowing house for delivery from the pregnancy, and the piglet at the age of between 10 and 14 days is transferred into a clean and comfortable breeding house from the farrowing house; when the level of a maternal antibody of the piglet at the age of between 10 and 14 days is in higher state, the piglet is moved away from the sow and is transferred into a cleaner environment; and the piglet feed for segregated early weaning adopts four stages to feed. The piglet has early weaning segregation time, high survival rate, and quick growth speed, the segregated early weaning of the piglet can save feeding cost of the sow, improve the yearly parity number of the sow, improve the utilization rate of the farrowing house, and reduce the probability that the piglet is infected with sow diseases, and a segregated early weaning technology of the piglet is suitable for the application of modern pig farms.

Description

technical field [0001] The invention belongs to the technical field of livestock feeding, and in particular relates to an early isolated weaning method for piglets. Background technique [0002] Segregated Early Weaning (SEW) is a new technology that has been promoted and used in Europe, North America, Japan, South Korea and Taiwan in the past ten years. SEW means that when the maternal antibody level of piglets is high and the proliferation of pathogenic bacteria and viruses is weak, piglets are isolated and raised in an environment with as few pathogens as possible, and a disease prevention barrier is established between sows and piglets to prevent lactating sows from Transmitting the disease to piglets can greatly reduce the chance of vertical transmission of pathogens, and can also greatly reduce the risk of common diseases in conventional pig farms. The United States began to promote this technology in 1992, and it is now widely used. Piglets are generally weaned at th...

Problems solved by technology

However, in production practice, because early isolated weaning of piglets breaks the normal growth process of piglets, weak piglets will have severe stress reactions, and poor handling may easily cause diarrhea, growth retardation, and even death of piglets

The supply of nutrition for piglets after weaning is the key factor to reduce stress and increase growth rate. There is no mature post-weaning feed for piglets in the existing market, which also limits the promotion of early isolated weaning technology for piglets
