Summary
This paper shows that the study of animal behaviour is a valuable aid to the improvement of the management of grazing livestock under extensive conditions. The food available to grazing animals in developing countries, and particularly in the dry season in the tropics, is often of very low quality and, in addition, is frequently available at low densities per unit area. Grazing ruminants attempt to adapt to these adverse conditions by increasing the time for which they graze each day and also by dispersing more widely. However, the time for which animals can graze may be limited by solar radiation and fly irritation in the day, and by the confining of the animals in pens at night. The adverse effects of the above limitations may be partially overcome when adapted local breeds are used. Dispersion of animals improves their ability to make use of extensive pasture and in order to encourage it, an understanding of the factors that affect it such as breed difference, social behaviour, adaptation and location of watering points and other unique environmental factors must be achieved. The paper concludes with recommendations of areas worth further research.
Résumé
Cet article montre que l'étude du comportement animal est une aide appréciable pour l'amélioration de la conduite du bétail au pâturage en élevage extensif. La nourriture disponible pour les animaux au pâturage dans les pays en développement, particulièrement en saison sèche sous les tropiques, est souvent de très faible qualité et, de plus, fréquemment disponible en faible densité par unité de surface. Les ruminants essaient de s'adapter à ces mauvaises conditions en augmentant leur temps de pâturage chaque jour et aussi en se dispersant plus. Cependant, le temps de pâturage peut être limité par les rayons du soleil et l'irritation due aux mouches le jour, et par le confinement des animaux à l'enclos la nuit. Ces effets défavorables peuvent être partiellement surmontés par l'utilisation de races locales adaptées. La dispersion des animaux améliore leur possibilité d'utilisation des pâturages extensifs et pour favouriser cela, une compréhension des facteurs qui les affectent comme la différence de race, le comportement social, l'adaptation et la situation des points d'eau et d'autres facteurs du milieu doivent être considérés. L'auteur conclut en recommandant d'autres recherches valables pour ces régions.
Resumen
Este articulo demuestra la importancia de estudiar el compartamiento de animales en pastoreo, para mejorar el manejo extensivo. El forraje disponible por unidad de superficie en países en vías de desarrollo es escaso y de mala calidad, sobre todo en época seca. Los rumiantes tratan de adaptarse a estas condiciones adversas incrementando el tiempo de pastoreo y dispersándose. Sin embargo el tiempo de pastoreo puede estar limitado por la radiación solar y la irritación causada por moscas durante el dia o porque los animales son encerrados durante la noche. Estos efectos pueden contrarrestarse utilizando razas criollas y bebederos estratégicamente localizados. Se requiere entonces más profundidad en estudios etológicos para incrementar la productividad de animales en pastoreo extensivo.
