Can the energetic supplementation of ewes influence the behavioral performance of their newborn lambs?
The present work evaluated the effect of an energetic supplement (an extra 15% of the requirement) intake during the last month of gestation on the suckling behavior of neonatal lambs born from these ewes.

| description | The present work evaluated the effect of an energetic supplement (an extra 15% of the requirement) intake during the last month of gestation on the suckling behavior of neonatal lambs born from these ewes. The study was performed in a semi-intensive and commercial flock under hot sub humid tropical conditions. 12 Pelibuey ewes and their 20 newborn lambs were included. Five lamb behaviors were evaluated: number of vocalizations (NV), attempts to stand up (ASU), latency to keep stands (LKS), started looking for the udder (SLU) and achieved an effective suckling (AES). Twelve lambs conformed the control group [CG] and came from seven ewes which received an energetic supplementation of 7.37 megajoules of metabolizable energy per day (MJ EM/d). Likewise, eight lambs conformed the treatment group [TG] and came from five ewes which received a high energetic supplementation of 10.85 MJ EM/d. Both groups of ewes gave birth simultaneously. Response variables were initially categorized in low-or-high intensity using their quartile distribution and considering the median value as the reference point and analyzed post-hoc with the Fisher test. Behaviors of high and low intensity in lambs were similar in four of the five variables observed for both treatments. A significant difference was observed in the frequency of ASU, in lambs born from treated ewes when compared with lambs born from control ewes (P = 0.0281). The present results suggest that under semi-extensive breeding systems, the extra supplementation of ewes at 15 % of their energetic requirements during the last pregnancy month is reflected just in a slight improvement of the lamb’s behaviors. |

El presente trabajo evaluó el efecto del consumo de un suplemento energético (15 % extra del requerimiento) durante el último mes de gestación sobre la conducta de amamantamiento de los corderos neonatos nacidos de estas ovejas. El estudio se realizó en una granja comercial semi-intensiva bajo condiciones tropicales cálidas subhúmedas. Se incluyeron 12 ovejas Pelibuey y sus 20 corderos recién nacidos. Se evaluaron cinco conductas del neonato: número de vocalizaciones (NV), intentos para ponerse en pie (IQP), latencia para ponerse pie (LDP), comienzo de la búsqueda de la ubre (BU) y amamantamiento efectivo (AE). Doce corderos conformaron el grupo control [GC] y provenían de 7 ovejas que recibieron una suplementación energética de 7.37 mega julios de energía metabolizable por día (MJ EM/d). Por su parte, ocho corderos conformaron el grupo tratado [GT] y provenían de 5 ovejas que recibieron una suplementación energética alta (10.85 MJ EM/d). Ambos grupos parieron de manera simultánea. Las variables de respuesta fueron inicialmente categorizadas como de baja o alta intensidad utilizando la distribución de sus cuartiles y considerando el valor de la mediana como punto de corte y analizadas post-hoc a través de la prueba de Fisher. Las conductas de alta y baja intensidad de los neonatos fueron similares en cuatro de los cinco comportamientos observados en ambos tratamientos. Se observó una diferencia significativa en la frecuencia de intentos para ponerse de pie en los corderos de ovejas tratadas comparados a los corderos de ovejas control (P = 0.0281). Estos resultados sugieren que en sistemas de crianza semi-intensivos, la suplementación extra del 15 % de las madres durante el último mes de gestación solo se refleja en una ligera mejoría de las conductas de sus neonatos.
