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 thepiglet 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
The invention belongs to the penkeeping technical field, be specifically related to a kind of segregated early weaning method of piglet.
Background technology
Piglet isolate in early days ablactation (Segregated Early Weaning, SEW), promptly be over past ten years in Europe, a kind of new technology of promoting the use of of ground such as North America, Japan, Korea S and China Taiwan.SEW is meant in piglet maternal antibody level higher; The cause of disease flora, when virus multiplication is more weak; The piglet isolated rearing in the least possible environment of pathogene, is set up the diseases prevention barrier between sow and piglet crowd, prevent that nursing sow infects eqpidemic disease to piglet; To reduce the probability of pathogene vertical transmission significantly, also can reduce the common disease risks in one-stop operation pig farm significantly.The U.S. began to promote present technique in 1992; Generally use at present; Piglet is generally in the wean of 21 ages in days, and European technology is the wean of 28 ages in days, separates feeding and management through early stage ablactation of piglet and ablactation piglet with sow; Thereby improve the nonproductive fate that swinery health status and productivity can also shorten sow simultaneously, improve the utilization ratio of the sow and the equipment of raising pigs.Piglet isolates trophic factors that ablactation mainly involves biological safety problem and the piglet on pig farm in early days and absorbs and utilize problem, and is promptly healthy with malicious sow with ill anti-to cross sow be the most dangerous propagating source in pig farm.Numerous disease is safe to sow itself; Immune; But can be under the situation that does not show any clinical symptoms; Give piglet with pathogen propagation when 15～20 days immune antiboidies through the breast milk transmission fade away in the nascent back of piglet, thereby cause the contagiosity eqpidemic disease of piglet, like Escherichia coli, streptococcus, salmonella, cloth disease, CSFV, parvovirus, rotavirus etc.Therefore, piglet is carried out 10～14 age in days ultra-early weanings and adopts the isolated rearing mode, the chance that receives disease infection just reduces greatly.But in production practices, because the piglet segregated early weaning has been broken the normal growth course of piglet, weak piglet can produce gross stress reaction, handles with great difficulty not cause grice diarrhoea, growth retardation even death.The supply of wean back piglet nutrition be reduce stress and improve the key factor of growth rate, the existing market does not also have feed behind the ripe weaned piglet, is the popularization of restriction piglet segregated early weaning technology yet.
Summary of the invention:
