Genetic Improvement of Sheep in Cyprus by Selection and/or Crossbreedings not easy and depends on the mode of inheritance of particular traits. The first step is to define the program’s aims or breeding goals, then to devise measurement techniques. A general outline of a commonly used strategy is presented in Fig. 1.

A Strategy for the Exploitation of Sheep Genotypes for Improved Flock PerformanceThere are two main methods for the genetic improvement of sheep in North Africa and West Asia. One is within-breed improvement of the native, mainly fat-tailed sheep while the other is the importation of genotypes from other areas to replace or be incorporated into the existing genotypes.

The Awassi Sheep Breeding Project in SyriaThe fat-tailed Awassi is indigenous to West Asia. In Syria it is the main source of milk, meat, and wool, accounting for about 69% of total meat production, 17% of milk production, and 40% of milk products. The value of sheep production is about 25% of total agricultural production.

Sheep Breeding in Jordan and a Proposed Awassi Breed Improvement ProgrammeThe tradition of keeping semi-nomadic flocks of small ruminants extends back to the start of civilization in the Middle East. As population and living standards have increased, farming practices and values have also changed, with increasing pressure to improve productivity in all sectors of agriculture including animal production.

Improving Livestock Production from Straw-Based Dietsnditions, straw is also deficient in the nutrients required by the microbes that digest straw e.g., Co and S, and in the minerals essential to the well-being of the animal e.g., P, Na, Mg, Cu, and Zn.
