Swine

The porcine respiratory disease complex is a model for use of immunomodulators. The respiratory clinical signs may result in variable mortality and morbidity rates, but they lead to a decreased growth rate and a worse feed efficiency ratio. It is a clear example of multifactorial disease with high economic impact.

Inmunicin Maymó affects the immune system of the pig:

  • Maximizes in the immune response in vaccine programs against PRRSV when given prior to the vaccine.
  • Improvement of production parameters:
    • Improves average daily gain.
    • Decreases mortality.
  • Efficacy results (3):
    • Swine producer with 2,135 sows in Lleida area, Spain.
    • Confirmed diagnosis of PRDC by PRRS.
    • Produces 3,600 pigs monthly.
    • Data of 28,200 untreated pigs were compared with data of 13,000 treated animals.

Rabbits

The purpose of the use of Inmunicin Maymó in rabbits is to improve the immune response after vaccination and, indirectly, to improve production parameters.

Currently, some field trials are being conducted to assess efficacy in rabbits and breeding females.


Turkeys

Inmunicin Maymó is used in turkeys to improve the immune status and to obtain better production parameters, as well as lower incidence of clinical problems. From an epidemiological point of view, the most critical phase is the brooding stage, since this phase is where viruses are recirculating and where attenuated live vaccines are applied.

In a preliminary study, several brooding batches were treated. Weight and mortality rate during the first 28 days of life were measured. Data about mortality are promising.

Another interesting use would be the improvement of vaccine response in replacements in female turkeys.
