aves caseras y en conejos, tuvo como
resultado una mejora rápida de la calidad
de la carcasa, y permitió la expansión y la
especialización de establecimientos de
crianza (Singleton, 2001).
Actualmente, la IA se realiza en casi
todos los animales de granja: vacas, yeguas,
ovejas, cabras, cerdas, conejas, pollos,
pavos entre otros. Sin embargo, las mejoras
tecnológicas de esta biotécnica provienen
mayoritariamente del éxito obtenido en la
producción de vacas lecheras (Vishwanath
2003). Durante la última década, el uso de
la IA en la producción de ganado porcino
ha aumentado considerablemente de 5% en
1990 hasta aproximadamente 60–70% en
el año 2000, sin embargo en relación al
ganado vacuno, raramente se utiliza semen
congelado (Singleton, 2001).
En este contexto, la inseminación
artificial disminuye y/o elimina
enfermedades sexuales, permite el uso
intensivo de machos con un alto valor
genético, el transporte rápido del semen a
diferentes lugares y también aumenta la
eficiencia de estimación del valor genético.
A escala mundial se realizan
anualmente más de 100 millones de
inseminaciones artificiales en vacunos, 40
millones en cerdos, 3,3 millones en ovejas
y 0,5 millones en cabras. Son muy pocos
los países en desarrollo donde se practica
la inseminación artificial en una escala que
repercuta considerablemente en la
producción ganadera Ruane &
Zimmermann, 2003). En el Perú sólo entre
el 3 y 4% de las vacas en producción son
inseminadas artificialmente, siendo los
mayores demandantes los productores de
las principales cuencas lecheras del país que
manejan ganadería intensiva y semi
extensiva. Existe interés por consolidar una
Red Nacional de Postas de Inseminación
Artificial, autogestionarias y sostenibles, bajo
un esquema empresarial, que permita
brindar el servicio con mayor efectividad.
Independiente del sector público, cada posta
cuenta con el apoyo efectivo de las
Municipalidades, Asociaciones de
Productores Ganaderos, Direcciones
Regionales Agrarias y Empresas Privadas.
El Ministerio de Agricultura y el Instituto
Interamericano de Cooperación para la
Agricultura en el Perú (IICA) entregaron
en el mes de enero del año en curso equipos
(1 moto, 2 tanques criogénicos, 1 maletín
de inseminación y 3 teléfonos celulares)
iniciando una primera etapa de reactivación
de 20 postas, ubicadas en los departamentos
de Puno, Cusco, Ica, Moquegua, Tacna y
Lima. En otros países la técnica de
Inseminación Artificial es una metodología
adoptada por muchos ganaderos, quienes
encuentran en ella el medio más barato y
factible para el mejoramiento de sus hatos
ganaderos.
SINCRONIZACIÓN E INDUCCIÓN
DE LA OVULACIÓN
El conocimiento de los mecanismos
involucrados en el control del ciclo estral
(de la ovulación, de la función luteal, de la
dinámica folicular, etc.) dan las bases para
comprender y establecer métodos
eficientes de sincronización del celo, así
como también la superovulación, es decir
los tratamientos que aumenten el número
fisiológico de ovulaciones (Callejas, 2001)
La determinación del momento ideal
para la inseminación en mamíferos de granja
es muy importante. En general, el momento
correcto de la inseminación en vacas es a
las 12 horas después del comienzo del estro
(Hunter & Greve, 1997). Sin embargo,
como la detección del estro no es siempre
fácil, la determinación del momento ideal
de la inseminación se dificulta. Es necesario
disponer de hembras receptoras en un
momento muy preciso y conocido del ciclo
estral cuando se procede a la transferencia
de embriones recientemente colectados o
producidos in vitro o que han sido
previamente obtenidos y congelados (Van
Eerdenburg et al, 1996).
Actualmente, usando el método de
hisopado vaginal, estamos logrando la
detección del celo en hembras de cuy. Los
resultados preliminares indican que el ciclo
estral en esta especie presenta tres estados
visibles al microscopio: diestro (336 horas),
proestro (14 horas) y estro (8horas).
