Swine Influenza

[nemo]

This past couple of months, areas of Bulacan, Neuva Ecija, Pampanga, and Tarlac was hit by an outbreak.  Most likely suspect is an Influeza virus.  The virus is more commonly known as the Swine flu virus. The disease is common in the Philippines and the usual sign are:

Fever
Anorexia
Coughning
Difficult of breathing
Discharged in the eyes and nose
Abortion if pregnant.

In the past this disease is not considered as threatening as it is now. In fact most farm do not vaccinate for this kind of virus.

So what went wrong?  Why is the disease become so damaging?  A possibility is the mutation of the virus. It mutated to a more virulent form and because most farmer do not vaccinate for swine influenza the sudden appearance of this mutated virus cost damage that is so swift.

Another possibility is that imported breeding hogs introduce a new virulent type of swine influenza in our country. This introduction of new virulent form cost the onslaught.

Treatment:  Because it is a virus there is no treatment for this disease. The most practical to do with this type of cases is to give antibiotic to prevent secondary infection and give immune boosters to increase production of immunoglobulins that will combat the virus. Restrict access to farm, do not allow anyone to enter your farm except your helper and you. Keep the dogs, rat, chicken out of the pen.

Dr.Nemo,thanks for the info,should we give shots to our hogs for this,at what age is it best to give the shots?what about pregnant sows?can this affect other livestock,saw on the news the UK now has blue tongue,cattle goats,I do not think they said hogs.Blue tongue looks bad.
Good Day To You Doc.                          mikey

To be honest your area is not that high risk compared to luzon. So, i would not suggest to you to vaccinate. Unless your local government say so.

Usually shots are given when they are still gilt(6-8 months old). Giving vaccine in pregnant sow is usually 3 weeks before they farrow. But this is depending also to the recommendation of the manufacturer of the drug.

Thanks Doc,will let brother in law know just in case,wants to be ready,one never knows,we always keep the hog operations in lock down,the problem in this world today people have the ability to travel far and wide in a short time span.
Good Day To You Doc.                                 mikey

Your welcome

Doc,
This thread is very helpful.  We have been using LincoSpectin from Pfizer.  5 days before weaning and 5 days after weaning.  Seems to be helpful.  The bigger ones, we were lucky enough to vaccinate with Flusure prior to the outbreak in Bataan area.

You are very fortunate.

Bulacan area has almost little piglet production last month and this month.

So expect that prices of pork will go high until May next year.

saan po tinatamaan ng swine flu sa sow ba o piglet?   maybe price will not go up next year dahil may importation.

[nemo]

Sows, actually yun sinabing hog cholera sa bulacan yung mga kakilala ko na vet swine flu ang kanilang diagnoses. 

[Slyfox]

tinatamaan ang sow tapos ma affected na ang piglet. tnx for the info doc

[nemo]

abortion is the result of this disease in pregnant sow.

anu ng latest na balita sa SFV meron pa ba? saang lugar?

Totoo po ba na matagal maglandi ang mga sow na tinamaan ng SFV? anu po ang dapat kong gawin?

thks

[nemo]

Wala na po akong naririnig.

As to scientific journal haven't read that SFV causes late heat/ovulation in animal.

Try to flush or give ADE muna.

Hi Doc Nemo,

Good day...

Nabasa ko yung mga questions regarding SFV. Doc puede pa bang paganakin ulit yung tinamaan ng Swine Flu Virus dati? Isang beses pa lang cya nanganak pero namatay lahat, ngayon kasalukuyang buntis ulit ito wala kayang magiging epekto sa magiging anak nya ulit?

Thank you,

Jim

Scientifically speaking adviseable na  to just cull it.  There are issues sometimes that this animal would be carrier of the disease.

Personal opinion:  Give it another chance.  IF you have  already vaccinated all your animal then chances of an outbreak is much smaller.  And also economic wise it difficult to produce another sow.

Possible effect is that it will have small litter size.
