Resumen
Immunological castration is a method for managing odor, by this technique is a
whole animal breeding free of boar taint by a non invasive method thus pigs are
castrated in order to reduce aggressive behavior, to facilitate management and
eliminate the characteristics odor of fresh carcass male pigs from integers which
becomes less appetizing. For this reason, it had been studied mechanisms to
reduce such problems by the method of castration being the most acceptable
results using the synthetic protein analogous GnRF (Improvac), vaccine which
allows the castration of male pigs to through the formation of antibodies against
the Gonadotropins Releasing Factor (GnRF), the same is the achieve similar
effects of surgical castration. Calderón, O. (2010) notes that inmunocastrads pigs
reached weights, weight gain, daily weight gain, feed conversion and back fat
thickness of 113.22 kg, 44.45 kg, 987.61 g, 3.69 and 12.05 mm, more efficient
pigs surgically castrated, being similar to those reported by Agroterra.com.
Concluding that the inmunocastration of pigs can record increasing weight of
34.44 %, compared to surgical castration increasing 33.31 %, so a better weight
gain, consequently better-feed conversion in pigs; recommending the
inmunocastration in pigs to eliminate the aggression, meat flavor and improve
productive parameters.
