Poultry production and its product consumption are progressively increasing globally. In Ethiopia, chicken production plays a great role as a primary supply of eggs and meat in rural and urban areas and as a source of income for smallholder farmers. The interest of the farmers to maximize poultry products is increasing. Therefore, different parts of the farmers are practicing crossbreeding unsystematically. However, crossbreeding is not advised and recommended by government due to its impact on genetic diversity and losing of the important traits of local chickens; thus, policy of the government has prepared different strategies to improve livestock development. There is no good breeding scheme introduced so far to avoid such kind of impacts or else regulator laws to avoid uncontrolled breeding activities. Therefore, conservation of locally adapted indigenous chicken breeds has become an important objective in sustainable animal breeding, as these breeds represent a unique genetic resource. And even if the indigenous chickens are low in productive performance, it has its unique and important characteristics such as brooding, tolerance of the disease and harsh environment of tropics, and giving good product under good management condition. Hence, breeding program targeting improvement of indigenous chicken should focus on within breed selection rather than crossbreeding with exotic chicken breeds, this would help to maintain the indigenous chicken unique attributes which are appreciated by producers and avoid genetic erosion and dilution and contribute to their conservation. Nevertheless, the indigenous chicken breeds in most African specifically in Ethiopia countries are little studied and the existing reports lack consistency. Therefore, further research is recommended to evaluate the performance, egg quality and carcass yield potentials of indigenous chickens under improved feeding and management systems.

Status and challenges of available feed resources and it's quality under the changing climate in Adami Tulu Districts of East Shoa Zone, Ethiopia

district of the East Shoa Zone Oromai Region, Eethiopia, with
the objectives to assess the existing status of feed resource under climate change and examine chemical composition. Feed
sample from grazing lands (protected communal (PC), protected
private (PP) and unprotected communal (UnPC) and crop residues were used for chemical composition analysis (23 from the
natural pasture (NP) and 48 from crop residues (CRs). Out of 23
herbaceous species identified in ATJK district, Cynodon dactilon
in ATJK district was the dominant grass species. The average
mean DMY (ton ha-1) of grass obtained from PPGL (2.43) and
PCGL (2.36) was significantly (P<0.01) higher than that from
UnPCGL(1.18) in ATJK . The mean value of CP contents of CRs
in ATJK district were 3.5±0.17 for maize Stover (MS) to 6.5±0.93
for Haricot bean (HCB) straw. The NDF contents of CRs were
between 63.5±1.83 for HCB to 79.74±1.24 for maize Stover (MS).
The ADF contents of CRs varied from WS (49.12±2.82) to HC
(52.63±1.16) in ATJK district. Generally, the nutritive values of
the evaluated feed resources were lower than the minimum and
should supplement with protein and energy source. The analysis of meteorological data of 30 years of ATJK district indicated
that; as temperature increase, the annual rainfall decrease and
increases the rate of crop water use. This situation of climate
change affects directly or indirectly the nutritive values and yields
of the crop, natural pasture, and production and productivity of
livestock and it will be suggested that to study the effects of climate on soil and animal feed nutrients.

The climate change especially global warming may highly influence production performance of farm animals throughout the world. Among the environmental variable that affect animals heat stress seems to be the intriguing factor making animal production challenging in many geographical locations in the world. All animals have a range of ambient environmental temperature termed as thermo neutral zone and temperature above or below this thermo neutral range of the animal create stress condition in animals. A thermal environment is a major factor that affects milk production in dairy cow especially on animals of high genetic merit. Milk yield decline by 0.2kgper unit increase thermal humidity index (THI) when it exceeded 72.The increase in milk yield, increase sensitivity of animals to thermal stress and decline the threshold temperature at which milk losses occur. Animals can adapt the hot environment, however the response mechanism are helpful for survival but are detrimental to productive and reproductive performances. Heat stress due to high ambient temperature accompanied with excess humidity cause infertility in most of the farm species and adverse effect on reproductive performance of farm animals. Changes in rainfall and temperature regimes may affect both the distribution and abundance of disease causing vectors, as can changes in the frequency of extreme events like animal feed quality, range condition and increase unpalatable species. Higher temperature resulting from climate change may increase the rate of development of certain pathogen or parasites that have one or more life cycle stages outside their animal host. This may shorten generation times and possible increase the total number of generations per year leading to higher pathogen or parasite population size. Therefore, the future directions to mitigate the effects of climate change were improving animal genetics and their health, improving their nutrition and improving manure and land management.

The chicken meat and egg resource in Ethiopia is play significant role in poverty alleviation generation additional income and religion or cultural reason. In general, poultry consumption accounts for less than 1% of the total annual food needs of farm households. The major constraints of poultry production in Ethiopia were meat and egg processing materials, prevailing disease, predators, nutrition, poor housing, weak agricultural extension service; low income level, religion and gender are also the constraints to poultry production and its meat consumption in Ethiopia. Generally the objectives of egg processing were; to safe products, to use as an ingredient for other foods, duration of shelflife to match expectation, convenient packaging for end users and meet local regulations in place or customer requirements.
