ABSTRACT.
Early maternal care contributes to the normal development of the physiological, social and emotional functions of the offspring. As sheep are a strongly gregarious species, separation and isolation of an individual from the flock provokes fear and, consequently a stress response. The first aim of this study was to compare the stress response to social isolation of rams that were reared by their mothers or artificially reared. A complementary objective was to compare the cortisol response to an ACTH challenge in both groups of rams. Rams were: 1) separated from their dams 24?36 h after birth (Week 0) and artificially fed with sheep milk until Week 10 (group AR, n = 14); or 2) reared by their dams until Week 10 (group DR, n = 13). The rams were then kept in separate, adjacent paddocks for the rest of the study. When they were 8 months old, 10 animals randomly selected from each group were isolated from the group in an unfamiliar pen during 10 min. Behavioural (the number of lines crossed, frequencies of vocalizations, eliminations, sniffing, escape attempts and freezing), physiological (heart and respiratory rate, and rectal temperature), biochemical (total blood proteins, globulins and albumin), and endocrine (serum cortisol concentrations) variables were recorded. Dam-reared rams eliminated (defecations + urinations) more times and crossed more lines during the social isolation test than AR lambs (P < 0.05). The increase in total proteins and albumin concentration after the social isolation test was also greater in DR than AR rams (P = 0.01 and P < 0.01 respectively). Artificially-reared rams had greater globulin concentration than DR rams after the test (P = 0.04). When rams were 2 years old, ACTH was administered to 10 rams randomly selected from each group, and the cortisol response was measured. Dam-reared rams had greater cortisol concentrations than AR rams at 150 and 180 min after the administration of ACTH (P < 0.05). In conclusion, artificially reared rams were less affected by social isolation and had lower adrenal response to an ACTH challenge than rams reared by their mothers. This study suggests that the relationship with the mother plays a key role in the development of rams? social behaviour. © 2018 Elsevier B.V. MenosABSTRACT.

Hay que tener presente que de los corderos que mueren en los primeros 30 días de vida, el 68% muere antes de las 72 horas pos nacimiento, siendo el complejo
inanición-exposición (pérdida de calor, hipotermia, agotamiento de reservas, otros) el responsable de la mayoría de esas muertes, y donde factores ambientales
como incremento del viento, abundantes precipitaciones y bajas temperaturas pueden incrementar los efectos adversos de este complejo (Mari, 1979; Fernández
Abella, 1995). Por lo tanto, se entiende que el acceso a información que permita prever o disminuir la influencia negativa del complejo inanición-exposición
sobre la supervivencia de corderos, puede traducirse en un incremento del porcentaje de señalada, con la consecuente mejora de los índices reproductivos y
económicos para el rubro ovino. En este contexto, el Secretariado Uruguayo de la Lana, las Facultades de Agronomía y Veterinaria, de la Universidad de la República, y el Instituto Nacional de Investigación Agropecuaria, conformaron en el año 2017 un equipo de trabajo para el desarrollo de una herramienta que permitiera poner a disposición de los productores de ovinos información de condiciones ambientales durante la parición. Como resultado del trabajo de este grupo se generó una herramienta llamada: Previsión de condiciones ambientales para la producción ovina, la cual se basa en la estimación de un índice biometeorológico denominado Índice de Enfriamiento o Chill Index. |
