Abstract
Con el objetivo de evaluar los tres tiempos de administración de la bacteria-toxoide Clostridium perfringens tipo C y Escherichia coli sobre el estado productivo e inmunológico en lechones lactantes; se empleó 36 marranas gestantes de la línea genética Camborough 29 y 149 lechones lactantes provenientes de estas. Las marranas fueron inmunizadas y distribuidas en 3 tratamientos, cada uno con 3 repeticiones: 86 días de gestación, 93 días de gestación y 100 días de gestación, siendo evaluados por un periodo de 49 días. Se realizó el análisis de varianza para los parámetros productivos y variabilidad de leucocitos; y el Xi ^2 para él % de morbimortalidad, donde la ganancia de peso diario tuvo diferencia estadísticamente significativa (P<0.05) entre el T1 y T3; al igual que la variabilidad de leucocitos, que hubo diferencia significativa (P<0.05) entre los promedios de los tres tratamientos. La morbilidad si tuvo relación (P<0.05) con los tiempos de inmunización, a diferencia de la mortalidad que no tuvo relación (P>0.05) con los tiempos de inmunización. La inmunización realizada a los 100 días de gestación registró mejor ganancia de peso diario y mayor concentración de leucocitos en los lechones lactantes.
ABSTRACT With the aim of evaluating the three administration times of the bacterium-toxoid Clostridium perfringens type C and Escherichia coli on the productive and immunological state in lactating piglets; 36 pregnant sows of the Camborough 29 genetic line and 149 lactating piglets were used. The sows were immunized and distributed in 3 treatments, each with 3 repetitions: 86 days of gestation, 93 days of gestation and 100 days of gestation, being evaluated for a period of 49 days. The analysis of variance was performed for the productive parameters and leukocyte variability; and the Xi ^ 2 for him% of morbidity and mortality, where the daily weight gain had a statistically significant difference (P <0.05) between T1 and T3; Like the variability of leukocytes, there was a significant difference (P <0.05) between the averages of the three treatments. Morbidity was related (P <0.05) to immunization times, unlike mortality that was not related (P> 0.05) to immunization times. Immunization performed at 100 days of gestation recorded better daily weight gain and higher leukocyte concentration in lactating piglets.
