Is it necessary to increase the amount of swine fever for 40 pound piglets?

2 yuan a pound,,, I was angry ,,, the test.

At present, there are three commonly used swine fever vaccines, namely live swine fever cell vaccine (cell seedling), live swine fever suckling rabbit tissue vaccine (tissue seedling), and swine fever spleen live rhea vaccine (tissue seedling). The toxicity content of each head of cell seedlings and tissue seedlings is not the same, each part of cell seedlings is not less than 750RID (rabbit body reaction volume), and each part of tissue seedlings is not less than 150RID.

Healthy pigs were inoculated, and the effect of cell seedlings and tissue seedlings was comparable; In the case of emergency inoculation, tissue seedlings are preferred over cell seedlings. The reason is that some tissue proteins in the tissue seedlings, especially the lymphokines in the spleen lymph seedlings, are immune promoters. However, it should be noted that tissue seedlings cannot be used for advanced immunization, and it may induce severe immune stress responses in piglets that have not eaten colostrum.

Immunization program Under normal circumstances, 25 30 days of age and 55 60 days of age are immunized once, and sows are immunized once before breeding. In areas with a high incidence of swine fever, piglets should be immunized in advance, that is, before eating colostrum.

Immunization dose: 1 cell seedling for advanced immunization, 4 cell seedlings or 2 suckling rabbit tissue seedlings or 1 spleen drenching seedling for other immunization. In this way, appropriately increasing the immune dose can break through the interference of maternal antibodies, reduce the toxinization and detoxification of immune pigs, and prevent subclinical infection of swine fever. However, it is not necessary to increase the amount too much, such as 10 or 20 heads, which will cause waste, and may also cause the immune tolerance of pigs, resulting in immune failure.

Generally, pigs are raised to 200 pounds to be slaughtered, during which the average feed to meat ratio of pigs is about: 1, but if you continue to raise, first, with the increase in the size of the pig, the energy consumption increases, and the second pig has passed the stage of rapid growth, and the weight gain rate has decreased greatly, so the feed to meat ratio will increase sharply.

Pigs weighing 400 pounds of feed have completely lost their economic value, and no one has yet studied how much feed and how much meat pigs will eat at this stage, so you can only experiment if you want to get the answer to your question.

Suckling pig (birth - 28 days) suckling pig feed first day;

The first day of piglet feed in the early stage (29-60 days);

Late piglet (60-77 days) piglet feed first day;

The first day of pig feed in growing pigs (78-119 days);

fattening pigs (120-168 days) large pig feed first day;

In the late fattening period (145--slaughter), the first day of intensive large pig feed.

The optimal daily gain, feed intake, feed-to-meat ratio of pigs at each stage is 1, 24-26 days old (daily weight gain of more than 267g, feed intake of more than 334g day, feed ratio of 27--56 days old (10--20kg) daily weight gain of more than 468g, feed intake of 766g or more, feed ratio of 57--88 days old (20--40kg) daily weight gain of more than 655g, feed intake of more than 1386g day, feed ratio of 89--124 days old (40--70kg) daily weight gain of more than 741g, feed intake of more than 1911g day, feed ratio of 125--158 days old (70--90kg) daily weight gain of more than 765g, feed intake of more than 2555g day, feed ratio of the whole process (daily weight gain of more than 653g, material ratio.

1: ** program for unexplained hyperthermia in piglets, pregnant pigs, and breeding boars.

Plan 1: Bingjian series piglets, pregnant pigs, breeding boars).

Bingjian series injection (pig homologous refined serum antibody freeze-dried powder) each set of this product according to 200kg weight ** nucleic acid peptide 400 kg bottle, depending on the severity of the disease, 12 times in a row, once a day.

Scheme 2: serum immunopeptide (porcine homologous refined serum immunoglobulin).

Serum immune peptide 200 kg bottle Cephalosporin Pioneer 300 kg set mixed injection, once a day, for three days.

Plan 3: 200 kg bottle of serum immune peptide and 400 kg bottle of nucleic acid peptide, once a day, for three days.

2. Health care program for fattening pigs and sows (available for pregnant animals).

Prevent mild swine fever, epierythrocytosis, influenza, constipation and other diseases.

Medication 1: Inject 20ml of 200 kg of serum immunopeptide into each head, and use it for 3 times. The use of this product about seven days before the sow gives birth can avoid the weakening of the piglet after the sow, the occurrence of multiple diseases, and reduce the mortality rate of piglets.

How many times do I need to be vaccinated against swine fever? It should be said that swine fever can only be fought. ** The drug vaccine has little effect. Let's get rid of the germs first.

Swine fever vaccine should be at least five times to suppress swine fever.

The dosage of swine fever vaccine is 50 servings.

<> live swine fever vaccine is generally 2 ml (1 serving). The live swine fever vaccine is suitable for the swine Changying herd where swine fever occurs, and can be used alone or in combination with anti-swine fever serum, it is an over-the-counter drug with a shelf life of about 1 year at minus 15 °C.
