The use of work animals began long before humankind
started to practice agriculture. The use of animal power is
now considered by many people to be archaic and
inefficient. Yet, despite the more than 50 years spent
promoting tractorization in developing countries, the
development gap between industrialized-countries and those
with weak, highly dependent economies has increased.
Moreover, the use of current production models, which are
more critically dependent on fossil fuel, cannot be
considered universally feasible. Alternative energy sources
such as the effective use of work animals must urgently be
established. Animals not only provide the means by which
millions of families make a living, but they also contribute to
ecologically and socially acceptable production systems.
Moreover, the efficiency of their energy inputs into crop
production is higher than that of machines. The rational use
of work animals has the potential to contribute, specifically,
to the living conditions and security of small-scale
