REPRODUCTIVE SEASONALITY AND ITS CONTROL IN SPANISH SHEEP AND GOATS

Sheep and goat breeds from subtropical, middle and high latitudes show seasonal changes in reproductive activity. In general, the breeding season starts in autumn and ends in winter, with anoestrus in spring/summer. An endogenous circannual rhythm driven and synchronised by the annual photoperiod cy...

description	Sheep and goat breeds from subtropical, middle and high latitudes show seasonal changes in reproductive activity. In general, the breeding season starts in autumn and ends in winter, with anoestrus in spring/summer. An endogenous circannual rhythm driven and synchronised by the annual photoperiod cycle regulates the onset and offset of the breeding season. However, the timing and duration of the breeding season can be affected by interactions between the photoperiod and factors such as breed, geographical origin, nutritional and lactational status, social interactions, and the season of parturition. Seasonality in reproduction is naturally accompanied by variation in the availability and price of meat, milk and cheese over the year, affecting the economy of farmers, consumers and the food industry alike. The control of reproduction outside the normal breeding season by inducing and synchronizing oestrus and ovulation plus the use of artificial insemination and/or natural mating would help ensure the year-round availability of products. This review describes the seasonal variation in the sexual activity of ovine and caprine species with special regard to local Spanish sheep and goats breeds, examines how the photoperiod regulates their annual reproductive cycle, and discusses a number of strategies that can be used to induce and synchronise ovulation outside the natural breeding season.

En tÃ©rminos generales, la estaciÃ³n reproductiva comienza en otoÃ±o y finaliza en invierno, con el perÃodo de anestro en primavera/verano, estando regulado el comienzo y final de la estaciÃ³n reproductiva por el ritmo endÃ³geno circanual sincronizado por el fotoperiodo. Sin embargo el inicio y duraciÃ³n de la estaciÃ³n reproductiva puede estar afectado por la interacciÃ³n del fotoperiodo con otros factores tales como la raza, origen geogrÃ¡fico, lactaciÃ³n y estado nutricional, interacciones sociales y Ã©poca del parto. Estas variaciones estacionales de la eficacia reproductiva, se traducen en variaciones en la oferta de leche y carne a lo largo del aÃ±o, afectando a los rendimientos econÃ³micos de los productores y los precios al consumidor. El control de la reproducciÃ³n fuera de la estaciÃ³n reproductiva mediante metodologÃas de inducciÃ³n y sincronizaciÃ³n de la ovulaciÃ³n, ya sea aplicando inseminaciÃ³n artificial o cubriciÃ³n natural, puede asegurar el mantenimiento de la oferta de estos productos, a lo largo del aÃ±o. Esta revisiÃ³n describe los cambios estacionales en la actividad reproductiva de ovinos y caprinos, con especial Ã©nfasis en las razas espaÃ±olas, profundizando en cÃ³mo el fotoperiodo regula el ciclo reproductivo anual, y valorando diferentes estrategias que pueden ser utilizadas para la inducciÃ³n y sincronizaciÃ³n de la ovulaciÃ³n fuera de la estaciÃ³n reproductiva.Universidad Autónoma de YucatanMCINN2011-12-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://www.revista.ccba.uady.mx/ojs/index.php/TSA/article/view/1350urn:ISSN:1870-0462-tsaes.v15iS1.1350Tropical and Subtropical Agroecosystems; Vol 15 (2012): Supplement 1, Special Issue - Advances in Animal ReproductionTropical and Subtropical Agroecosystems; Vol 15 (2012): Supplement 1, Special Issue - Advances in Animal Reproduction1870-0462reponame:Tropical and Subtropical Agroecosystemsinstname:UNIVERSIDAD AUTÓNOMA DE YUCATÁNinstacron:UADYenghttps://www.revista.ccba.uady.mx/ojs/index.php/TSA/article/view/1350/702https://www.revista.ccba.uady.mx/ojs/index.php/TSA/article/downloadSuppFile/1350/549https://www.revista.ccba.uady.mx/ojs/index.php/TSA/article/downloadSuppFile/1350/550info:eu-repo/semantics/openAccessoai:ojs.www.revista.ccba.uady.mx:article/13502024-08-22T17:23:01Z
