브로일러 계군에서 질병으로 인한 피해를 파악하는데는 어느 분야보다도 자료의 부족을 절감하게 된다. 필자가 파악하기로는 몇개 사료회사에서 사료의 질을 파악하는 방편의 일환으로 생존율을 조사하고 있으나 자료를 얻기가 쉽지 않고 또한 자료를 구한다 치더라도 조사대상 농장의 전반적인 사양관리상의 수준 등을 고려할 때 그것이 국내에서의 브로일러의 생존율을 대표하기보다 왜곡된 자료일 가능성이 많다. 그래도 유일하게 신빙성이 있는 자료는 가축위생연구소와 대학에서 실시하고 있는 가금질병 진단써비스 자료이다. (중략)

브로일러 사육과정에서 3주 이후에 흔히 발생하는 다리, 관절, 발톱 등의 이상으로 압사 또는 발육부전이 나타나 외모가 흉스러운 상품으로 인하여 경제적 손실과 사료요구율을 저하시키는 예가 종종 발생한다. 이때 농장에서는 급여사료의 미량성분 부족이나 병아리의 불량추에서 발생하는 것으로만 생각할 수 있으나 그 요인은 여러 가지가 있을 수 있어 최근 외국에서의 문헌에 실질적인 발생요인을 기술하였기에 인용, 기고하여 각 농장에서 피해를 최소화할 수 있도록 조치하는데 도움이 되었으면 한다.

An experiment was carried out to evaluate the feeding value of hydrolyzed leather meal (HLM) replacing fish meal A total of 240 day-old female chicks of Maniker strain was divided into 20 groups of 12 birds ecah. Each groups was assigned to one of the five dietary treatments (0. 1. 2, 4 and 6% HLM). The feeding trial was conducted for six weeks. Results obtained are summarized as follows: 1. The HLM used in this experiment contained 74.41% crude protein. 17.0% crude ash and 2.0% chromium. Pepsin digestibility of the protein was measured to be 85%. Amino acid contents were also determined 2. The inclusion of HLM up to 4% in broiler rations did not depress the growth rate, feed consumption and feed efficiency of experimental birds. However, these performance parameters were significantly (p＜0.05) depressed when fed 6% HLM. These results indicate that HLM in place of fish meal can be used up to 4% in tile broiler rations.

This study was carried out to investigate the influence of dietary xanthophylls supplementation on the antioxidant and color properties of broiler meat. After raised for 6 weeks, broilers were slaughtered and stored at 3$^{\circ}C$ for 9 days. Experimental treatments were divided into lutein, canthaxanthin, astaxanthin and capsanthin. The supplementation level was adjusted to 30 ppm. The pH values of the thigh was higher(P<0.05) than those of the breast. No differences in pH values were shown among xanthophylls treatments. Xanthophylls supplementation to chick inhibited the formation of TBARS(Thiobarbituric acid reactive substance) and POV(lipid peroxide) of broiler meat during storage. At 9 day storage, the TBARS and POV of xanthophylls treatment decreased as compared to the control(P<0.05). The broiler meats fed astaxanthin had antioxidant effects in both breast and thigh. Dietary xanthophyll supplementation to chick decreased the CIE L(lightness) and increased a(redness) values of broiler meats fed canthaxanthin increased(P<0.05) during storage. These results indicated that broiler meats fed xanthophylls had dark-red color and antioxidant effect during refrigerated storage.

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.
