This study aimed to investigate the physicochemical properties of chicken breast ham manufactured with broiler (BR), spent broiler breeder hen (SBBH), and spent laying hen (SLH). The water holding capacity and final yield of chicken breast ham manufactured with SLH was significantly lower than chicken breast ham manufactured with BR and SBBH (P<0.05). The lightness and redness of chicken breast ham manufactured with SBBH were significantly higher than those of chicken breast ham manufactured with SLH (P<0.05). The yellowness of chicken breast ham manufactured with BR and SLH was significantly higher than that of chicken breast ham manufactured with SBBH (P<0.05). The shear force of chicken breast ham manufactured with SLH was the highest. The tenderness and overall acceptability of chicken breast ham manufactured with BR and SBBH were significantly higher than those of chicken breast ham manufactured with SLH. Therefore, SBBH and SLH can lead to various textures of chicken breast hams.

산란노계를 적기에 좋은 가격으로 처리하기가 점점 어려워지고 있다. 군납의 문은 더욱 좁아지고 육가공분야에서의 이용도 아직 요원하다. 이러한 산란노계의 처리와 효율적 이용방안은 무엇인가.

본회는 올해부터 산란노계출하 알선사업을 시행한다. 본 사업의 궁극적인 목적은 산란노계산업 활성화 및 산란계산업 발전에 기여하며, 산란계 농장의 노계출하를 안정적으로 적정가격에 수취할 수 있는 기반을 만들어 보고자 함에 있다. 또한 노계정육에 대한 소비가 늘어나면서 노계업체 또한 안정적인 작업물량 확보가 중요해졌고, 상호 협력하여 중간손실비용을 줄임으로써 효율을 높여 산업을 발전시킨다는데 큰 의미를 두고 있다. 산란노계출하 알선사업에 대해 간략하게나마 소개하고자 한다.

The objective of this study was to determine the effect of the meat from spent laying hen on the shelf-life and physicochemical properties of emulsified sausage. Four types of sausage were made: 0% (Control), 10% (T1), 20% (T2) and 30% (T3) of spent hen meat added. Each sausage type was tested in triplicate. The addition of spent hen meat resulted in decreased crude fat and cooking loss, and increased WHC (water holding capacity), CIE $a^*$ and hardness. Values for crude fat and cooking loss were significantly decreased by the addition of spent laying hen meat relative to the control (P<0.05). Especially, T3 was significantly (P<0.05) decreased compare to other treatment groups. Spent laying hen meat addition had no significantly effects on moisture, crude protein, crude ash, pH, WHC, TBARS (thiobarbituric acid reactive substance) values, shear force, total plate counts (TPC), CIE $L^*$ and $b^*$ values. In conclusion, this study demonstrates that the addition of spent laying hen meat to emulsified sausages tended to improve sausage quality.

산란계 경영에 있어서 실제 사업의 처음이 초생추 또는 중추의 입식이라면 노계도태는 그 끝이라고 할 수 있다. 계사를 청소하고 소독을 한 후 입추시기와 품종 등을 신중히 고려해 병아리를 입식하고 각종 백신을 접종하고 세심하게 길러내어 성계로 만들어 놓고 갖은 질병의 지뢰밭을 통과하면서 최대한으로 계란을 낳게 하다보면 어느덧 우리의 알 기계는 노후되어 도태시기를 결정하게 된다. 필자는 지난 15년간 고창양계라는 부화장에 근무하면서 주로 병아리 판매업무에 종사하면서 전국의 사양가분들과 접촉해온 경험이 있는 바, 대부분의 농장주들이 마지막 단계인 이 노계도태를 단순히 병아리를 새로 받기 위해 즉흥적으로 그 시기를 결정하거나, 거꾸로 노계를 도태한 후 서둘러 신규입추를 추진하는 등 실로 비합리적인 경우가 너무 많았음을 기억하면서 이번 기회를 통해 노계도태의 모든 부분을 정리해 보고자 한다.

This study was performed to investigate the development of smoked chicken using old laying hens. Seventy two-weeks-old, spent laying hens were fed commercial feed (control) supplemented with 100 IU ${\alpha}$-tocopherol plus 10% squid liver oil (treatment) for 15 days and slaughtered. Smoked chickens were manufactured with spent laying hens in this study, Moisture and crude ash contents in smoked chicken of treatments were higher (P＜0.05) than those of control group due to the feeding 100 IU ${\alpha}$-tocopherol plus 10% squid liver oil. No differences were observed in fatty acid and amino acid composition between control and treatments. In sensory evaluation, the springiness of smoked chicken was evaluated optimum for 32% consumer. The elastic, blend, specific flavor and smell of the smoked chicken of the treatment were not different from those of the control. However, 46% of tested panel answered that the springiness was higher in the treated-group due to the feeding 100 IU ${\alpha}$-tocopherol plus 10% squid liver oil. These results indicated that smoked chickens would be developed with spent laying hen after feeding 100 IU ${\alpha}$-tocopherol plus 10% squid liver oil and sensory evaluation.

The effect of supplemental yellow ${\beta}$-8-Apo-carotenoic acid ethyl ester (ACA) (0~300mg/kg feed) on its accumulation in each body part of laying hens and the pigmentation in egg yolk was determined. The chickens used in this study were 78-wk-old ISA brown laying hens. ACA significantly affected the color of the bodies of laying hens. The yellowness ($b^*$) but not the redness ($a^*$) and, the lightness ($L^*$) of the skin, and muscle as measured by a colorimeter significantly (P < 0.05) increased when ACA was fed at 50~100 mg/kg feed. Egg yolk color was also significantly affected by feeding ACA longer than 2 days (P < 0.05) at the levels higher than 50 mg/kg feed. Conclusively, ACA is recommended for improving yellowness of skin.
