Quality of egg could be categories internal and external quality of egg.Įxternal factors including cleanliness, freshness, and egg weight and Gas concentration and orie-ntation is also play a prime importance. For maintain of egg quality, temperature, humidity, Source of nutrients for human and it is nutritious, economical and easily Local chicken raised in different production management system.Įgg quality traits refers that the characteristics of an egg which affect The goal of thisĪnalysis was the quality of intern-al and external egg from exotic and Quality features in the light of all-inclusive researches. Of local and exotic breed chicken for production of egg for its specific The objective of this review was to demonstrate the potential The duration of egg storage and technique also affect albumen and yolk Handling techniques affected the internal and external egg quality and For betterīreeding strategies and reproductive parameters of chicken production valuable egg quality traits are needed. Transportation, and egg market influence by yolk color. Strength are very significant egg quality traits to handle egg during One of the determinant factors of externalĪnd internal egg quality traits are embryonic development of an eggĪnd the viability of the new hatched chick. Egg quality couldīe seen in two ways internal egg quality (yolk and albumin heightĪnd diameter, yolk color, yolk and albumin weight, Haugh unit) andĮxternal egg quality (egg weight, length and shell thickness) on theĮgg content and egg shell.

Rural area is free range scavenging system in which they are allowed toĮxercise freely around the home during at day time. The major production system of chickens in Show a large variation in body conformation, plumage color, comb The mostĭominant chicken types reared in Ethiopia are local ecotypes, which Potential farm animal genetic resources in the country.
This implies that local chickens are playing significant role as Poor quality feeds and have products that are preferred by consumers.
They play an important role in theĮconomic development of rural communities and they are known-n toīe relatively resistant to some infectious diseases, good converters of Production systems to supply the fast-growing human population with BackyardĬhicken production is therefore important in low-income, food-deficit Income hatching for replacement home consumption. They are reared in theĬountry mainly for social and economic requirements including cash
Vital role for livelihood of rural farmers as source of income and to Indigenous chicken production in Ethiopia is playing a The current annual per capita consumption is not greater than 2 eggs Indigenous chickens is estimated at 40-60 small eggs. It implies that improved exotic chicken play a great role to satisfy theĮgg demand of the population. The estimated annualĮgg production of 59 million chickens is 151.47 million egg of whichĦ9.23 million (47.7%) eggs found from the improved exotic chicken. Internal egg quality External egg quality Indigenous chicken Improved chicken IntroductionĬhicken population in Ethiopia is over 59 million out of whichĥ0.91 million (85.7%) of chickens are indigenous and improvedĮxotic chicken comprise about 8.51 million (14.3%) and which isĬlustered in to 8 indigenous chickens’ breeds. Similarly, internal and external egg quality variations have been observed between the indigenous and improved chicken populations hence, a profoundly egg chemical composition evaluation is needed to show the level of egg composition differentiation and similarity between them. Therefore, the present review study suggests that exotic chicken like that of local chicken have ability to produce good egg quality which is directly favors the economic preference of consumers under extensive feedingbased production system. The egg qualities of chickens depend on their genotype, age of hen, quality and quantity of feed and storage condition of egg, embryonic development of the egg and production system. Under village condition, local and exotic chickens have higher Hugh unit and deep yellow color. The result of the studies on the quality egg from chicken (exotic and local) obtained from different management have shown that there are significant difference both the internal and external egg quality characteristics. The goal of this analysis was the quality of egg from exotic and local chicken raised in different production management system. The aim of this review was to show the possibilities of using local and exotic breed chicken for production of egg for its specific quality features in the light of all-inclusive researches.
