Manejo de las explotaciones de ganado ovino en Extremadura: efecto del tamaño del rebaño

Abstract

[ES]El objetivo del trabajo es conocer el efecto del tamaño de los rebaños de ganado ovino de carne sobre el manejo en las distintas etapas del ciclo reproductivo en condiciones reales de explotación en Extremadura. Para ello se utilizó la información correspondiente a 724 encuestas realizadas en ganaderías de Oviso, S.C.L. entre octubre de 2009 y enero de 2010. La información recogida incluyó una valoración del manejo en: precubrición, cubrición, preparto, parto, post-parto y lactación. Se establecieron 6 grupos de tamaño, con una disminución en el número de explotaciones al aumentar el tamaño de los grupos. Al aumentar el tamaño de los rebaños aumenta el número de parideras/año y se acorta la duración de las cubriciones. La valoración del manejo durante las etapas del ciclo reproductivo aumentó (mejor manejo) al hacerlo el tamaño de los rebaños desde los más pequeños hasta el grupo 5 (de 1200 a 2000 ovejas) y disminuir en el grupo de mayor tamaño. La calificación global es relativamente baja y sólo superan el 60% de la calificación máxima las explotaciones entre 1200 y 2000 cabezas, tamaño que podemos considerar como óptimo desde el punto de vista productivo y del manejo reproductivo de las explotaciones.

[EN]The study aims to understand the differences among farms of different sizes on the management at different stages of reproductive cycle in real conditions of exploitation of sheep meat in Extremadura. We used the information on surveys conducted in 724 herds in Oviso, SCL between October 2009 and January 2010. The information collected included an assessment of management on: premating, mating,prelambing, lambing, postlambing and lactation. 6 groups were established in size, with a decrease in the number of farms by increasing the size of the groups. By increasing the herd size increases the number of lambing / year and shortens the duration of mating. The assessment of handling during the stages of the reproductive cycle increase as the herd size from the smallest to the group 5 (from 1200 to 2000 ewes) and decrease in the larger group. The overall rating is relatively low and only exceeded 60% of the maximum grade holdings between 1200 and 2000 heads, a size that can be considered as optimal from the standpoint of production and reproductive management of farms.
