The effect of stocking density on the growth and meat quality of native Korean chickens was investigated. A total of 364 one-day-old native Korean chickens were randomly assigned to one of 5 treatments, each of which was replicated 4 times. Five distinct stocking densities-14, 15, 16, 18, and 22 birds/㎡-were compared. The diet was fed ad libitum for 10 weeks. Results indicated that the final body weight, body weight gain, and feed intake were lower (P<0.05) for the 22 birds/㎡ stock density as compared to the other stock densities. There was no significant difference in the feed conversion ratio, proximate analysis (DM, crude protein, crude fat, and crude ash), water-holding capacity, and cooking loss among the different stock densities. These results indicate that increasing the stock density to 22 birds/㎡ elicits some negative effects on the growth performance and meat quality of Korean-native chickens.

This study was conducted to evaluate the potential of using laying hens as meat type chickens. Male broiler (Ross 308, R3), laying hens (Hy-Line Brown, HL), and Korean native chickens (Hanhyup-3, H3) were used, and 100 heads of each were prepared. Carcass characteristics, meat quality, and sensory quality characteristics were compared as analysis items. The rearing environment and feed for all treatments were identical to the broiler rearing manual, and the lighting system was maintained at 23L:1D. Feed and water were provided ad libitum. The test ended when the average weight of each treatment group reached 1.5 kg, and individuals of similar weight were randomly selected and compared. As a result of this study, the live weight of the selected individuals was approximately 1.5 kg, which was similar for all treatments (P>0.05). However, carcass weight and ratio and breast meat production were highest in R3, while HL had higher ratios of legs, wings, and neck (P<0.05). The H3 group showed high pH and WHC levels and low cooking loss, and R3 improved chicken meat color (P<0.05). In particular, the fat content in meat was lowest in HL (P<0.01). Nucleic acid substances ATP, Hx, ADP, AMP, and INO were abundant in R3, and IMP content was highest in HL (P<0.05). In sensory evaluation, all treatments showed similar characteristics and overall preferences (P>0.05). Based on the findings, it appears that HL, a male laying hen, produces meat with unique characteristics such as low fat content and high IMP content.

소득수준이 높아지면서 소비자들의 축산물 구매 성향이 품질과 안전성 우선으로 바뀌고 있다. 닭고기 역시 HACCP, 친환경 농산물 인증마크, 등급판정, 품질보증마크 등을 통해 보다 더 안전하고 믿을 수 있는 닭고기를 소비자에게 공급하고 있다. 하지만 지정마크의 홍보 부족으로 정작 소비자들은 마크의 의미를 모르는 경우가 많이 있다. 소비자들이 안전하고 믿을 수 있는 닭고기를 선택할 수 있도록 이번호 특집에서는 닭고기 제품에 표시되어 있는 지정마크에 대해 자세히 알아보자

지난 4월 1일부터 닭고기 등급판정 시범사업이 실시되고 있다. 9월 현재 체리부로, 농협계육가공분사, 하림 3개 업체가 참여하고 있다. 이들 업체들은 닭고기 등급제 참여로 국내산 닭고기의 위생적인 가공처리와 품질 고급화를 촉진하는 전환점이 되며 고품질을 요구하는 소비자들의 신규 창출 및 유통업체와 소비자간 믿을 수 있는 거래 기회를 제공할 것으로 기대하고 있다. 닭고기 등급판정 시범사업이 시작된 지 5개월이 지났는데 이런 참여업체들의 반응을 점검해 보았다.

This paper reports the results of the research on the effects of probiotic yogurt on the microbiological quality, pH, and sensorial characteristics of fresh chicken meat when packed with probiotic yogurt. The chicken meat pieces were packed with yogurt and were stored at $10^{\circ}C$ for 7 days. Samples were taken after 0, 2, 4, and 7 days of storage, and were analyzed for total bacterial count, E. coli, and coliform, and for the chemical parameters, including the pH. In the control group (packed without yogurt), the Pseudomonas species predominated when the spoilage was obvious after 4-day storage at $10^{\circ}C$. The yogurt-mixed chicken meat package was found to have a significantly lower total viable count and significantly fewer coliform bacteria during storage. Furthermore, the yogurt package showed a growth-inhibiting effect on the Salmonella typhimurium, which were inoculated into the chicken meat pieces for the study. The study findings indicate that probiotic yogurt can be used in packing fresh chicken meat to decrease the population of spoilage bacteria therein and to extend its shelf life.
