C ME containing reconstituted freeze-dried coconut milk did as well
and in many cases better than refrigerated milk extender in the fertility
trials. In Uganda where the CME technique was first adopted in 1963,
substantial gains have been made in expanding the practise of artificial
insemination. Since 1963 they' ve added over 10 new A.l. sub-stations
to the 20 which were already in existence. Plans are currently underway
to increase the present number of yearly inseminations with CME from
approximately 9,000 to 25,000 by 1970. In both Paraguay and El
Salvador small-scale experiments have been tried to prolong the life
span of frozen sperm after thawing by re-extending and storing them in
C ME at room temperatures. Paraguay (1) reported 9 pregnancies out of
30 first inseminations, and El Salvador (2) 2 out of 5 with re-extended
semen in CME which was 24 hours old at the time of insemination.

The results obtained from several countries demonstrate the useful-
ness and versatility of CME in improving and expanding artificial insem-
ination practices. This is particularly evident in countries where arti-
ficial insemination and consequently the upgrading of cattle production
has lagged behind because the large scale use of low temperature methods
for the conservation of bull semen has been impractical and too costly.
