  • This study was performed to evaluate the effect of the level of stocking density of housing with or without window on chicken meat quality. The incidence of $1^+$ grade of whole chicken housed with window significantly influenced by stocking density. The incidence of $1^+$ grade chicken at high stocking density ($0.050\;m^2$/head), standard stocking density ($0.066\;m^2$/head), and low stocking density ($0.083\;m^2$/head) was 26, 52, and 66%, respectively. Breast muscle of chicken housed with window and with low stocking density showed higher incidence of $1^+$ grade than high stocking density. Also minor and severe PSE (pale, soft, extractive) incidence of chicken meat were showed 4% each, while the $1^+$ grade chicken was not appeared at low density. In chicken thigh, the incidence rate was not affected by stocking density. In chicken housed without window, the incidence of $1^+$ grade chicken in high, standard, and low stocking density was 18, 8, and 46%, respectively. Also, the incidence of $1^+$ grade chicken breast was 2.6 times higher than the chicken in low stocking density. However, incidence of $1^+$ grade thigh was not affected by the stocking density. These results suggest that high stocking density significantly reduced the incidence of $1^+$ grade chicken meat regardless of housing with or without window.

  • 본회는 지난 6월 22일 대전 소재 리베라호텔에서 '2010전국채란인대회'를 개최하였다. 이날 참석한 채란농가를 대상으로 채란업의 안정적인 방안을 모색하기 위해 '계란유통구조 개선'을 주요 내용으로 여론조사를 실시하였다. 설문조사에 참여한 채란농가는 총 234명으로 농가당 평균 49,567수(성계 기준)를 사육하는 것으로 조사되었다. 계사형태는 개방계사가 69.7%, 무창계사가 30.3% 형태를 보였고, 사육시설은 A형케이지가 68.4%, 직립식케이지가 29.6%, 기타 2%로 나타났다. 본고에서는 설문 내용을 바탕으로 분석 정리하였다.
