to commercial strains under village systems. An increasing loss of genetic diversity has been observed for all agriculturally used species, and more than half of
common livestock breeds especially poultry are now endangered or at risk of extinction [57]. Agriculturally important genetic stocks include those selected for various
production-related characteristics. These include egg production, body shape, feeduse efficiency, leg strength, and disease resistance. Ironically, these selected stocks
that are particularly vulnerable when funds become limiting, because improvements
in production-related traits require many years and a relatively large number of birds
each year. With the increasing attention given to the characterization of the African
genetic resource [58]. The first phase of characterization involves the identification of
populations based on morphological evaluations. Morphometric measurements have
been used to evaluate the characteristics of various Egyptian local strains of chickens
[59], and production and some physiological aspects as well. Recently, Molecular
markers have proven to be superior to the conventional methods for determining
gene flow in chicken stocks. Also, information on hereditary variety can give essential contribution to design successful strategies for preservation and restoration of
characteristic local breeds. The generation of the apparatuses in advance of sequencing (molecular markers, linkage maps, BAC libraries, and so on.) was being started
to preserve the accessible unrivaled germplasm of the Egyptian indigenous chickens
utilizing different molecular methods [60–62]. Even though the local breeds contain
genes germane to their adaptation to specific environments and local breeding objectives, the local chickens confront genetic disintegration which may prompt the loss
of profitable genetic variability in particular traits. Like this, indigenous chicken has
continuously been replaced and substituted by intensive industrial stocks, undermining genetic power and diversity. Besides, Policies to protect the local species will
require more scientific contributions on the genetic structure in its local dissemination extend. The assumption is that exotic breeds are better. On the other hand, this
is not generally the case.
5.2 Animal Genetic Diversity
The primary main purpose in domesticated animals’ developments in Egypt is to give
animal protein to take care of the growing demand in the short run. This has been
done regularly with little thought for environment and supportability factors. In this
setting, local breeds are infrequently wrongly thought of as something of the past. In
Egypt, the normal lactation drain yield in Friesian dairy animals is less of what 33%
of its genetic potential. Exotic breeds have an important role in expanding national
production, yet their utilization must be supported, and the expansion of their genetics must be under control. The Egyptian dairy cattle had eight breeds: two of them
were vanished or reduced (African aurochs and Hamitic longhorn) while the other six
breeds are Baladi, Domiette, Egyptian, Maryuti, Menufi, and Saidi, are yet present.
Conversely, the Egyptian animal breeders mentioned that the Egyptian local cattle
are just a one breed called Baladi. Indigenous population may have distinctive names,
