Summary

Analyses of the 1991 lambing records of 27 flocks comprising 15020 ewes on the Ceylanpinar State Farm showed clearly that age significantly affects fertility, abortion and still births, twinning, number of lambs born per ewe served and per ewe lambed. Mean twinning rates for the 2, 3, 4, 5, 6, 7 and over age groups were 2.1, 8, 0, 15.3, 14.8, 12.4, and 13.4 % respectively. Fecundity increased until the ages of 4 and 5, but started to decline with further increase in age.

Previous research on the same farm concluded that high plane of nutrition (flushing) can increase twinning significantly (127.7 versus 106.1 %). Another research showed that twinning can be successfully increased to over 65 % by using intra-vaginal sponges.

In a recent study conducted on Ceylanpinar, mean lactation length and lactation yield were found to be 168.3 days, 174.6 kg; 187.2 days, 231.4 kg and 175.6 days, 170.5 kg for the exceptional ewes of the national flocks, exceptional ewes of the State Farm and the control ewes respectively. The outstanding ewes of Ceylanpinar State Farm demonstrated a clear superiority over the other two groups with respect to lactation yield.

Due to its high milk producing potential Awassi breed can be utilized as sire in improving milk production of many non-improved Asiatic and African breeds. In Turkey it has been successfully used in crossing with Akkaraman and Da^oliç. It has also been crossed with some indigenous breeds of Iran, Cyprus, Egypt, Iraq, Spain and Yugoslavia with the objective of increasing milk production in the crossbreds.

However for the genetic improvement of the Awassi sheep, the unique population of Ceylanpìnar State Farm represents a good experimental material. A variation of 97.5-469.2 kg in lactation yield among all the State Farm Awassi indicates the scope for the success of the future genetic improvement of this breed.
