Basic principles in pig breeding

Food is essential to the success of a pig. Without them it would be impossible to end happily and profitable time, the release of a population of pigs, much less fattening. If we go deeper, there would be any use to help us improve fertility, fertility and birth of our little universe hog.

Because of this, food plants strive to produce high quality, which can be used by the producer on their farms, with the certainty that they are purchasing the ideal fuel for our animals to complete their production cycle in time and weight, making it gain, the initial investment in purchasing the balance.

Likewise, companies that work are dedicated to the production of premixes, with which the swine producer makes its own food.

The detail is on those factors that we get out of hand as:

• The grains we use.
• The cost of them.
• Cereals by government ordinance requires us to purchase.
• The origin of the grain.
• Proper handling of raw materials.
• Good use of the storage silos.
• Proper maintenance of the silos.

From these and other factors we would be aware, but how hard we try, we can have some blunder, we would trigger the end of a long journey, perhaps the presence of inappropriate levels of mycotoxins.

Of course, that the control of fungi in cereals with fungicides is effective, the use of scavengers in the food too, and maybe it's easier to control if we produce our food. If we are to buy, commercial insurance companies will be watching this. In addition to mycotoxins, also affect the liver: Antibacterials that are broken in it, infectious diseases, bacterial toxins, stress, among others, that detract from the animal capacity. But one way or another, the producer can also be protected with other products on the market to aid the liver in pressing moments of an attack by these silent enemies.

There are products that have natural active ingredients for use in both drinking water and in food, which have, among others, and cholagogues choleretic effects. Correct and improve liver function by increasing the excretion of bile, essential for the absorption of fat soluble vitamins and fatty acids, which are active in tissue restitution. This increase bile flow causes an increased removal of enteric bacteria in the stool, reducing the potential of causing enteric diseases. Similarly, increased lipid digestion and absorption of fat-soluble amino acids, thus improving feed conversion and weight gain. Thanks to the improvement and increase of liver function induced by the extract of Cynara scolymus or better known as artichoke, plus choline chloride, yields a hepatoprotective effect and aid liver function. Choleretic and cholagogue action of its components improves the hepatic metabolism of healthy animals and allows quick recovery of productive capacity in animals affected by toxic processes.

The constant attack immunosuppressive items as viruses, bacteria, mycotoxins, has encouraged scientists worldwide to develop compounds from diverse backgrounds and with different mechanisms of action, capable of modulating the immune response. The bacterial origin are perhaps the best studied, they act on the host's ability, either specific or nonspecific, as this modulation is specifically tied to a given antigen. These compounds are called immunomodulators and physiological or pharmacological action on the immune system, optimizing its defensive reaction to external aggression is defined as immunomodulation.

These immunomodulatory activated defense cells. Macrophages are empowered to perform phagocytosis, T cells increase secretion of cytokines, B cells produce more antibodies. These immunomodulatory activated defense cells.

Immunomodulators enhance cell-mediated immunity, making it easier to antigen presentation by macrophages to T cells and thus trigger a series of steps to reach the immunological destruction of the pathogen. Also, modulate antibody production accelerating cell division of B lymphocytes, increasing the production of antibodies.

In a conference held in Spain where veterinarians were recognized related to pig farming in the country, discussed the latest knowledge and advances in research of the disease swine, immunosuppression and immunomodulation.

As referred to immunomodulation, showed different programs using an immunomodulatory compound inactivated cells of Propionibacterium granulosum and lipopolysaccharide of E. cell coli.

In all cases we recommend the application of the dose before delivery to the pig breeding to further enrich the colostrum that the pig is going to take in order to increase their level of immunity.

Other programs were:

* The immunomodulator and stimulating immunity in bacterial infections
* Shorten the duration of antibiotic treatment.
* The immunomodulator and stimulating immunity in viral infections.
* Improved therapeutic response to infection in animals whose immune system is damaged by PRRS.
* Improved the effect of vaccination of AD by increasing the primary response against viral antigens. * Combat immunosuppressive effects of circovirus.
