“…En los últimos 15 años esta tecnología se ha usado para el estudio de diferentes variables de comportamiento y seguimiento de animales domésticos: ovejas, [17][18][19] cerdos ibéricos 20 y ganado bovino. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] La tecnología GPRS (General Packet Radio Service) es utilizada en telefonía móvil y permite la transmisión y recepción de datos desde una terminal por medio de paquetes. Las tradicionales redes GSM (Global System for Mobile Communications) no se adaptan adecuadamente a las necesidades de envío de datos con terminales móviles, por ello surge una nueva tecnología portadora denominada GPRS que unifica el mundo IP (Internet Protocol) con el mundo de la telefonía móvil, creándose toda una red paralela a la red GSM y orientada exclusivamente a la transmisión de datos usando la red de telefonía por vía satélite.…”

ResumenEn los últimos años, el comportamiento del ganado vacuno en pastoreo ha sido poco estudiado, en comparación con el comportamiento en granja. Además, en determinadas razas criadas en sistemas extensivos, la presencia humana puede modificar o interrumpir sus pautas etológicas: los animales se alejan de quien los observa. El uso de la tecnología GPS-GPRS en la monitorización de bovinos explotados en régimen extensivo nos permite disponer de datos de interés en tiempo real; proporciona información sobre desplazamientos, distancias recorridas, territorio pastoreado, zonas más frecuentadas, pautas de comportamiento, etc. En esta investigación, se monitorizaron, mediante la implantación de collares GPS, 21 vacas de diferentes edades, de tres ganaderías de la provincia de Salamanca pertenecientes a la raza bovina lidia. El estudio se llevó a cabo durante ocho meses, distribuimos a los animales en cercados de diferentes dimensiones y características orográficas, y recogimos datos de su posición geográfica cada 15 minutos. Además de corroborar el buen funcionamiento de los dispositivos GPS, se estableció el área de campeo para cada animal: la media fue de 56 ha. Elaboramos un gráfico de su ritmo circadiano con las distancias recorridas por horas, donde se observa una tendencia a iniciar la actividad diaria unas horas antes del amanecer, atenuar su actividad al anochecer y durante la noche, así como mantener una fase de reposo nocturno de aproximadamente siete horas. También analizamos la distancia diaria recorrida (3.15 km media/animal), donde encontramos diferencias sustanciales en función de la edad, la superficie/animal disponible en el cercado, el día y la noche, y la época del año. Nuestros resultados son valiosos para un mejor manejo de las superficies pastables con cercados en los que los animales utilicen toda la superficie disponible.Palabras clave: GPS, GPRS, distribución espacial, pastoreo, sistemas extensivos, percepción remota, telemetría, ámbito hogareño.Monitorización del ganado lidia con tecnología GPS-GPRS; estudio del comportamiento en pastoreo y la distribución espacial

“…Global Positioning Systems (GPS) and Geographical Information Systems can be used efficiently to gather data on flock or herd spatial behaviour (Barbari et al, 2006) and are currently the most popular tool for studying the distribution of grazing pressure on rangeland. Recently, research has also investigated the potential of virtual fencing to control animal distribution in extensive grazing systems.…”

In the countries surrounding the Mediterranean basin, most of the semi-natural grazing lands are covered by rangelands. Rangelands can be defined as highly heterogeneous natural vegetation communities with high conservation value, growing in harsh environments (poor soils, unfavourable climatic conditions). In the recent socio-economic context, traditional livestock grazing practices that enabled one to reconcile rangeland preservation and animal production no longer apply, especially because they require labour that has become scarce and costly. The consequence is rangeland degradation, due to underutilization in Southern Europe, and overutilization in Northern Africa. We analysed issues raised by rangeland utilization in livestock farming systems of the Mediterranean basin. Based on a review of the scientific literature about rangeland utilization in this area, we argue that the best way to reconcile animal production and rangeland preservation would be to promote management practices allowing animals to express their adaptative capacities in feeding behaviour and productive response. In order to propose management practices adapted to extensive and simplified systems, we conclude that research efforts should focus on: (i) proposing a functional characterization of vegetation heterogeneity at the scale of the vegetation community, (ii) validating the criteria determining animals' foraging behaviour on Mediterranean rangelands, (iii) developing and using simulation models to test management strategies against seasonal and long-term variability in climatic conditions and (iv) evaluating the potential of modern technologies for improving rangeland utilization.

“…When goats and sheep were herded, they still travelled a similar distance, which increased to 10.1 km/day. Barbari et al (2006) noted that the spatial distribution of grazing cattle was much wider at night than during the day, which may correspond to a greater distance travelled at night than during the day. These researchers also noted a bimodal distribution over the 24-h clock.…”

“…These researchers also noted a bimodal distribution over the 24-h clock. However, cattle tended to increase activity from dawn until noon, and then decrease until late afternoon at which time activity increased until near midnight (Barbari et al 2006). This differs from the goats and sheep on this study by a lag of 4 h in the morning and a longer time interval between peaks.…”

Goats and sheep often graze together and guardian dogs are commonly used for protection from predators. The objective of this experiment was to characterise how goats, sheep and guardian dogs interact spatially when grazing the same pasture by use of global positioning system (GPS) collars as an unobtrusive means of behaviour monitoring. In 2002 and 2003, three meat goats and two sheep in a group of 12 of each species were randomly chosen and, along with a guard dog, fitted with GPS collars. Minimum distance travelled between consecutive 30-min fixes and distance between any two animals at the same fix time were calculated using spherical geometry. In 2002, the dog travelled the least between fixes during the day but more at night than either goats or sheep. However, in 2003, there was not a significant species difference in distance travelled in 24 h or during the day or night. All species travelled significantly more during day than night but none were stationary at night. Distance amongst goats and between sheep tended to be greater during day than night; distance between goats and sheep was greater than the distance amongst goats or between sheep. Hence, goats and sheep interacted as two separate entities rather than as one large herd/flock. Distance between the dog and goats was closer than between the dog and sheep, indicating a clear preference of the dog for goats that could relate to a difference in previous exposure to the two species. In summary, based on these findings protection by a guardian dog would be greater for a small group of goats than sheep and much greater than for a mixed species group. Or, with a large group of grazing animals, the number of dogs required for a certain level of protection would rank goats B sheep B mixture of goats and sheep.
