1: Kev xaiv lub sijhawm pub mis

Nrog rau qhov nce ntawm piglets qhov hnyav, qhov kev xav tau ntawm cov as-ham txhua hnub nce zuj zus.Tom qab lub ncov ntawm lub sij hawm pub mis, piglets yuav tsum tau weaned raws sij hawm raws li poob ntawm sows 'yuag thiab Backfat.Feem ntau ntawm cov chaw ua liaj ua teb loj feem ntau xaiv cov yub rau li 21 hnub, tab sis qhov yuav tsum tau muaj cov cuab yeej tsim khoom yog siab rau 21 hnub weaning.Kev ua liaj ua teb tuaj yeem xaiv yub rau 21-28 hnub raws li lub cev lub cev ntawm cov noob qoob loo (rov qab rog <5 hli, lub cev hnyav <10-15kg).

2: Qhov cuam tshuam ntawm kev txiav tawm ntawm Piglets

Cov kev ntxhov siab ntawm cov piglets weaned muaj xws li: pub hloov pauv, los ntawm cov kua pub rau khoom noj;Ib puag ncig ntawm kev pub mis thiab kev tswj hwm tau hloov ntawm chav tsev me nyuam mus rau chaw zov me nyuam;Tus cwj pwm ntawm kev sib ntaus sib tua ntawm pab pawg thiab mob hlwb ntawm weaned piglets tom qab tawm hauv sows.

Weaning stress syndrome (pwsd)

Nws hais txog kev mob raws plab, rog rog, tsis muaj sia nyob, tus nqi noj zaub mov tsis zoo, kev loj hlob qeeb, stagnation ntawm kev loj hlob thiab kev loj hlob, thiab txawm tias tsim cov npua tawv los ntawm ntau yam kev ntxhov siab thaum lub sij hawm weaning.

Lub ntsiab kev kho mob tshwm sim tau raws li nram no

Pub noj ntawm npua:

Qee tus npua tsis noj ib qho khoom noj li ntawm 30-60 teev ntawm qhov hws, kev loj hlob stagnation lossis qhov hnyav nce (feem ntau hu ua rog poob), thiab lub voj voog pub mis yog ncua ntev dua 15-20 hnub;

Mob plab:

Cov kab mob raws plab yog 30-100%, nrog rau qhov nruab nrab ntawm 50%, thiab qhov hnyav tuag yog 15%, nrog rau edema;

Txo kev tiv thaiv:

Kev mob plab ua rau tsis muaj zog tiv thaiv kab mob, tsis muaj zog tiv thaiv kab mob, thiab yooj yim kis kab mob thib ob ntawm lwm yam kab mob.

Pathological hloov tau raws li nram no

Pathogenic microorganism kab mob yog ib qho tseem ceeb ua rau mob raws plab los ntawm kev nyuaj siab syndrome nyob rau hauv weaned piglets.Kev mob raws plab tshwm sim los ntawm kab mob kab mob feem ntau tshwm sim los ntawm cov kab mob Escherichia coli thiab Salmonella.Qhov no feem ntau yog vim thaum cev xeeb tub, vim tias cov tshuaj tiv thaiv kab mob hauv niam mis thiab lwm cov tshuaj inhibitors hauv cov mis nyuj inhibit qhov kev loj hlob ntawm E. coli, piglets feem ntau tsis tsim tus kab mob no.

Tom qab weaning, lub digestive enzymes nyob rau hauv cov hnyuv ntawm piglets txo, lub digestion thiab nqus tau ntawm cov zaub mov muaj peev xwm txo, protein spoilage thiab fermentation nce nyob rau hauv lub tom ntej ib feem ntawm txoj hnyuv, thiab cov khoom ntawm niam cov tshuaj tiv thaiv yog cuam tshuam, ua rau poob. ntawm kev tiv thaiv kab mob, uas yooj yim rau kev kis kab mob thiab raws plab.

Physiologic:

Gastric acid secretion tsis txaus;Tom qab hws, qhov chaw ntawm lactic acid raug txiav, qhov tso tawm ntawm gastric acid tseem tsawg heev, thiab acidity nyob rau hauv lub plab ntawm piglets yog tsis txaus, uas txwv tsis pub lub activation ntawm Pepsinogen, txo qhov tsim ntawm pepsin, thiab muaj feem xyuam rau lub digestive system. pub, tshwj xeeb tshaj yog cov protein.Indigestion feed muab tej yam kev mob rau kev loj hlob ntawm pathogenic Escherichia coli thiab lwm yam kab mob pathogenic nyob rau hauv cov hnyuv me, thaum lub sij hawm kev loj hlob ntawm Lactobacillus yog inhibited, nws ua rau indigestion, plab hnyuv permeability teeb meem thiab raws plab nyob rau hauv piglets, qhia kev nyuaj siab syndrome;

Cov enzymes digestive hauv plab hnyuv tau tsawg dua;Thaum muaj hnub nyoog 4-5 lub lis piam, lub plab zom mov ntawm piglets tseem tsis paub qab hau thiab tsis tuaj yeem tso cov enzymes digestive txaus.Weaning piglets yog ib hom kev ntxhov siab, uas tuaj yeem txo cov ntsiab lus thiab kev ua haujlwm ntawm digestive enzymes.Weaned piglets los ntawm niam mis mus rau cog raws li pub, ob qhov sib txawv ntawm cov khoom noj khoom haus, ua ke nrog lub zog siab thiab muaj protein ntau pub, ua rau raws plab vim plab zom mov.

Khoom noj khoom haus:

Vim tias cov kua txiv hmab txiv ntoo tsawg dua, cov khoom noj tsis zoo ntawm cov plab hnyuv siab raum, cov enzymes qis, thiab cov ntsiab lus ntawm gastric acid tsis txaus, yog tias cov ntsiab lus ntawm cov protein ntau hauv cov khoom noj ntau dhau, nws yuav ua rau plab zom mov thiab raws plab.Cov ntsiab lus muaj roj ntau hauv cov khoom noj, tshwj xeeb tshaj yog tsiaj rog, yog ib qho yooj yim ua rau raws plab hauv cov piglets weaned.Cog lectin thiab antitrypsin hauv pub tuaj yeem txo qhov kev siv ntawm cov khoom soybean rau piglets.Antigen protein nyob rau hauv soybean protein tuaj yeem ua rau mob plab hnyuv, villus atrophy, cuam tshuam rau kev zom zaub mov thiab kev nqus ntawm cov as-ham, thiab thaum kawg ua rau kev ntxhov siab ntxhov siab hauv piglets.

Environmental Factors:

Thaum qhov kub ntawm qhov sib txawv nruab hnub thiab hmo ntuj tshaj 10 ° Thaum cov av noo siab dhau lawm, qhov tshwm sim ntawm kev mob raws plab kuj yuav nce ntxiv.

3: Tswj kev siv cov kev ntxhov siab ntawm lub cev

Cov lus teb tsis zoo rau kev ntxhov siab yuav ua rau tsis muaj kev puas tsuaj rau piglets, suav nrog atrophy ntawm plab hnyuv villi, tob zuj zus ntawm crypt, qhov hnyav nce, nce kev tuag, thiab lwm yam, thiab tseem ua rau muaj ntau yam kab mob (xws li Streptococcus);Kev loj hlob ntawm piglets nrog qhov sib sib zog nqus qhov muag thiab gluteal groove poob qis heev, thiab lub sijhawm tua yuav nce ntau dua ib hlis.

Yuav ua li cas los tswj kev siv cov kev ntxhov siab ntawm lub cev, ua rau piglets maj mam txhim kho qib ntawm kev pub mis, yog cov ntsiab lus ntawm peb theem kev siv tshuab, peb yuav ua cov lus piav qhia ntxaws hauv ntu hauv qab no.

Teeb meem hauv kev txiav thiab tu

1: Cov rog ntau dua (qhov hnyav nce tsis zoo) tshwm sim hauv kev txiav ≤ 7d;

2: Qhov kev faib ua feem ntawm cov npua tsis muaj zog nce tom qab weaning (kev hloov pauv, kev yug me nyuam);

3: Tus nqi ntawm kev tuag nce;

Kev loj hlob ntawm npua poob qis nrog kev loj hlob ntawm lub hnub nyoog.Piglets pom kev loj hlob ntau dua ua ntej 9-13w.Txoj hauv kev kom tau txais txiaj ntsig zoo tshaj plaws ntawm kev lag luam yog yuav ua li cas kom siv tag nrho cov txiaj ntsig kev loj hlob ntawm theem no!

Cov txiaj ntsig tau pom tias los ntawm kev txiav tawm mus rau 9-10w, txawm hais tias lub peev xwm tsim tau ntawm piglets yog siab heev, nws tsis yog qhov zoo tshaj plaws hauv kev tsim npua tiag;

Yuav ua li cas kom ceev cov piglets loj hlob thiab ua kom lawv qhov hnyav 9W ncav cuag 28-30kg yog tus yuam sij los txhim kho qhov ua tau zoo ntawm kev yug npua, muaj ntau qhov txuas thiab cov txheej txheem yuav tsum tau ua;

Kev kawm thaum ntxov ntawm cov dej thiab cov khoom noj khoom haus tuaj yeem ua rau piglets paub cov dej haus thiab kev noj zaub mov, uas tuaj yeem siv cov txiaj ntsig super pub mis ntawm kev ntxhov siab, txhim kho qib pub ntawm piglets, thiab muab kev ua si tag nrho rau kev loj hlob ntawm piglets ua ntej 9- 10 lub lis piam;

Kev noj zaub mov tsis pub dhau 42 hnub tom qab txiav qhov kev loj hlob ntawm tag nrho lub neej!Kev tswj hwm kev siv cov kev ntxhov siab los ntawm kev txo qis los txhim kho qib ntawm kev noj zaub mov tuaj yeem ua rau 42 hnub qub noj zaub mov kom ntau dua li qhov ua tau.

Cov hnub xav tau rau piglets kom ncav cuag 20kg lub cev qhov hnyav tom qab weaning (21 hnub) muaj kev sib raug zoo nrog kev noj haus lub zog.Thaum lub zog digestible ntawm cov khoom noj nce mus txog 3.63 megacalories / kg, qhov zoo tshaj plaws kev ua tau zoo tus nqi yuav ua tau tiav.Lub zog digestible ntawm kev txuag kev noj haus tsis tuaj yeem ncav cuag 3.63 megacalories / kg.Nyob rau hauv cov txheej txheem ntau lawm, tsim nyog additives xws li "Tributyrin,Diludine" ntawm Shandong E.Fine tuaj yeem xaiv los txhim kho lub zog digestible ntawm kev noj haus, txhawm rau ua tiav cov nqi zoo tshaj plaws.

Daim duab qhia tias:

Kev loj hlob txuas ntxiv tom qab weaning tseem ceeb heev!Kev puas tsuaj rau lub plab zom mov yog qhov tsawg kawg nkaus;

Kev tiv thaiv muaj zog, tsis tshua muaj kab mob, kev tiv thaiv tshuaj zoo thiab ntau yam tshuaj tiv thaiv, qib kev noj qab haus huv;

Thawj txoj kev pub mis: piglets tau weaned, ces poob mis nyuj rog, tom qab ntawd rov qab, thiab tom qab ntawd nce qhov hnyav (li 20-25 hnub), uas ua rau lub sijhawm pub mis ntev thiab nce tus nqi yug me nyuam;

Txoj kev pub mis tam sim no: txo qhov kev ntxhov siab, txo cov txheej txheem kev ntxhov siab ntawm piglets tom qab weaning, lub sij hawm ntawm slaughter yuav luv;

Thaum kawg, nws txo cov nqi thiab txhim kho cov txiaj ntsig kev lag luam

Pub mis tom qab weaning

Qhov hnyav nce hauv thawj lub limtiam ntawm kev txiav yog qhov tseem ceeb heev (Qhov hnyav nce hauv thawj lub lim tiam: 1kg?160-250g / taub hau / W?) Yog tias koj tsis nce phaus lossis txawm poob phaus hauv thawj lub lim tiam, nws yuav ua rau muaj qhov tshwm sim loj;

Cov piglets thaum ntxov weaned yuav tsum tau zoo kub (26-28 ℃) nyob rau hauv thawj lub lim tiam (txias kev nyuaj siab tom qab weaning yuav ua rau mob loj tshwm sim): kev noj zaub mov tsis txaus, txo digestibility, txo tus kab mob, raws plab, thiab ntau yam kab mob tsis ua hauj lwm;

Txuas ntxiv pub ua ntej weaning pub (siab palatability, siab digestibility, siab zoo)

Tom qab weaning, piglets yuav tsum tau pub kom sai li sai tau los xyuas kom meej cov khoom noj khoom haus tsis tu ncua ntawm plab hnyuv;

Muaj ib hnub tom qab rhais chaw, nws tau pom tias piglets lub plab yog shriveled, uas qhia tau hais tias lawv tseem tsis tau paub txog qhov pub, yog li yuav tsum tau ntsuas kom induce lawv noj sai li sai tau.Dej?

Txhawm rau tswj kev mob raws plab, cov tshuaj thiab cov khoom siv raw yuav tsum raug xaiv;
