Examination of egg production with the sub-standard size of the barley replaced the basal feed on the laying hens

The two experiments were conducted to study the effects of different levels of the barley replaced feed to determine their influence on egg qualities. In experiment 1, hens were allocated to each of 5 treatments for 28 days. First group were given diet based on maize (the basal feed) as the control. The two of five groups of hens were given diet of the levels (15% or 30%) replaced of the basal feed. The other two of five groups of hens were given diet of the levels (15% or 30%) replaced of the basal feed supplemented with a 5% crab husk respectively. In experiment 2, hens were allocated to each of 4 treatments for 70 days. First group was given diet based (the basal feed) on maize as the control. The second group of hens was given the basal feed supplemented with a 5% crab husk. The third group of hens was given diet of the level (45%) replaced of the basal feed. The fourth group of hens was given diet of the level (45%) replaced of the basal feed supplemented with a 5% crab husk. As a result, there was no influence in the egg qualities. However, it improved egg yolk color of the basal feed supplemented with a 5% crab husk, while that of the barley replaced the basal feed decreased significantly (p0.05). Moreover, the feed did not influence on the fatty acid contents in yolk. We examined the antibody test of Newcastle disease (ND) with hemagglutination inhibition (HI) test after 14 days of the vaccination. HI tires of the control plot (the basal feed) were higher than that of the barley replaced the basal feed supplemented with a 5% crab husk plot (p0.05). Also, the boiled eggs prepared from the control plot (the basal feed) and the barley feeding replaced the basal feed supplemented with a 5% crab husk plot were evaluated by sensory test. The barley feeding replaced the basal feed supplemented with a 5% crab husk plot showed higher values for the taste of yolk (p0.05). The barley feeding replaced the basal feed with crab husk 5% plot was significantly favored in the sensory test (p0.05).
