Project Achievements
Indonesia
The most important achievement on the
prolific sheep component was the development
of a criterion for identifying homozygous (1p F)
ewes. This will significantly speed up the
development of the two lines. In the hair sheep
program, further evidence on the remarkable
regularity of reproduction of the local North
Sumatran ewes was obtained, and a health
component was added to this program.

sheep approached that of the larger Finnsheep
and Dorset breeds in a more favorable environ-
ber 9-15, 1990. A total of 28 papers were presented.
Attendance was approximately 60
people, with invited participants from USA,
Australia, Thailand, Philippines and Malaysia.
A proceedings is being prepared, which will
include two papers from the breeding project.
An invited paper entitled 'The Prolificacy
Gene of Javanese Sheep" was presented at
an international conference on "Major Genes for
Reproduction in Sheep," held in Toulouse,
France, on July 16-18,1990.
Results of a two-year study that was a
part of the Outreach Pilot Project (OPP) was
summarized in a paper to be submitted to a
research journal. A paper on the performance of
North Sumatran sheep was accepted for publication
in Small Ruminant Research.
Other publications from the Indonesia
CRSP breeding project are reported in the
"Publications" section of this report.

One of the major accomplishments was
the publication of the manual, 'Sheep Production
and Management in a Mediterranean
Climate: The Agropastoral System of Morocco,"
in English and in French.
