Second FAO Electronic Conference on Tropical Feeds
Livestock Feed Resources within Integrated Farming Systems

Abstract of twenty second paper, from David Little et al.

Questions that might stimulate discussion on this topic
include:

1. Do you have similar figures showing the advantage of using
by-products and of recycling wastes at small farm level?

2. Do you have economic figures on the benefit of integrating
different animal species on the farm for optimizing the use of
by-products and wastes?

3. In your region, is cultural aversion a major constraint
preventing the use of livestock wastes (pig and poultry
manure...) in fish culture? What are the other constraints?

4. What would be the impact of the introduction of a biodigestor
in the systems reviewed in this paper?

5. How do you compare these systems with the one exposed by
George Chan concerning south-eastern China (Eleventh paper)?

ABSTRACT

An analysis of production and distribution of rice products
within a village, Ban Thap Hai, in Udorn Thani, Northeast
Thailand suggests that current patterns of utilisation constrains
use in integrated fish culture. Most rice bran (80%) is used by
the rice miller to feed pigs. The remaining 'grower's share' is
split between use as a supplementary feed for scavenging poultry
and for fish. The extent of, and constraints to, integration
between livestock and fish in the current situation are
discussed. Potential fish production through direct use of
ricebran and from livestock wastes is modelled based on data from
on-station and on-farm research. The impact of changing
distribution and use of surplus rice paddy and rice bran in the
village on livestock and fish production is then considered.
Feeding management for scavenging poultry has an important effect
on productivity of both poultry and, subsequently, the amount of
wastes available for fish culture. Inorganic fertilisation
increases fish yields from feeding limited amounts of ricebran
directly to fish or via poultry by over 100%. Retention of rice
byproducts by the growers could have a major impact on total
poultry and fish production in the village, potentially doubling
the amount of fish that can be produced. The importance of
off-farm factors in constraining smallholders' use of rice
byproducts for livestock and fish will continue to increase.
