Effects of Salmonella typhimurium lipopolysacharide(LPS) and dietary krill meal on the Growth and feed utilization were investigated in broiler chicks. Eight cages of five newly hatched chicks each were assigned and fed to one of the experimental diets containing 0.0,(basal) 0.5 or 1.0% krill meal during 3 weeks of experimental period. And half(four) of the eight cages were i.p. injected with saline or LPS(Immune response activation) every alternate day three times beginning 8 day-old during 2 week of age. Dietary krill meal did not affect growth, feed efficiency, nitrogen balance(NB), uric acid excretion, and ME utilization when the saline was injected. However, the immune response activation lowered daily gain and feed intake and NB and increased uric acid excretion, and the relative liver and spleen weight. Also, birds fed diet containing krill meal 1.0% reduced the feed efficiency and increased spleen weight, and ME and NB or ME required for gain compared with those fed basal and krill meal 0.5% diets in LPS-injected chicks. During recovery period from the immunological stress in 3rd week of age, the krill meal diet reduced the weight of liver and spleen, The results showcd that dietary krill meal did not affect the growth of broiler chicks, but the higher uric acid excretion or dietary ME value indicated the increased protein decomposition or absorption of dietary energy sources in immune response activated birds.

Effect of dietary krill meal levels on the cellular immunity was studied in broiler chicks activated immune response. One day old male broiler chicks(Ross) were fed the experimental krill meal 0.0(basal), 0.5, 1.0 and 2.0% diets for 3wks. Blood TNF-α activity, ovotransferrin level and Con A induced proliferation of PBMC and splenocytes after 24 hr(21 d age) of the croton oil 10㎕ injection intra- musculary at the age of 20 days compared to the control olive oil. Krill meal diets did not affect growth performance of broiler chicks and plasma ovotransferrin levels but decreased significantly(p<0.0001) TNF-α like activity and proliferation of PBMC relative to krill meal 0.0% diet. And the proliferation of splenocytes were significantly(p<0.05) increased in birds fed krill meal 1.0% diet relative to krill meal 0.5 and 2.0% diets. The croton oil injection induced a significant(p<0.0001) increases in the TNF-α activity or the PBMC proliferation and enhanced circulating ovotransferrin levels relative to the olive oil. In birds injected with the croton oil the proliferation of PBMC was reduced linearly with the increase of dietary krill meal levels, and the proliferation of splenocytes was decreased in the krill meal 1.0 and 2.0% diets relative to olive oil. These results indicated that dietary krill meal changed the innate and cellular immunity in broiler chicks activated by the injection of croton oil.

In order to observe the infectivity, growth and development and adult morphology of Metorchis orientalis, a total of 40 chicks were experimentally infected with 100 metacercariae respectively, collected from Pseuderasbora larva. The worms of various developmental stages were recovered from chicks at 1.5, 3, 5, 7, 9, 11, 1:k and 21 days after infection, and they were prepared for morphological observations and measurements. All of the worms were found in the gallbladders of chicks, and their recovery rate was 32% in average. The growth of the body was rapid from 9 to 11 days after infection. The genital primordia appeared in 1.5 and 3-day old worms, and ovary and testes were first observed in 5-day old worms. Thereafter, genital organs gradually matured and completed up to 11 days after infection. The adult worm was leaf-like, and possessed a con- voluted tubular seminal vesicle, an ovoid ovary, a sac-like seminal receptacle, 2 lobed-testes and follicular vitellaria. Eggs were $31.9{\times}15.3{\;}\mu\textrm{m}$ in average size, ellipsoid to elliptical in shape and possessed abopercular thickenings. From the above results, it is concluded that M. orientalis grows in sigmoid pattern in chicks, and their genital organs fully matul.e between days 9 and 11. It is also confirmed that a chick is a new definitive host of M. orientalis.

In order to utilize health food chick bean as a raw material for cosmetics, the skin improvement effect of a mask pack made of chickpea Natto fermented with Bacillus subtilis Natto strain was studied. Powder obtained by lyophilization of chickpea Natto was applied to a facial mask pack as a paste formulation. This Natto pack was applied to subjects in their 50s and 60s to investigate their effect on skin improvement. As the number of treatments of Natto pack increased, the skin was improved and the improvement effect was remarkable after 4 treatments. After four times treatments, moisture content and sebaceous secretion increased by $8.4{\pm}3.6%p$ and $4.0{\pm}2.3%p$, respectively. Skin pores and wrinkles were also decreased by $1.8{\pm}0.3%p$ and $1.8{\pm}0.9%p$, respectively. Skin pigmentation decreased by $1.3{\pm}0.2%p$ and skin tone also increased from 55.2% to 55.9%. These results indicate that Natto product obtained by fermenting chickpea has the effect of improving skin such as moisturizing, pore, wrinkle, pigmentation, sebum secretion and skin tone, and can be used as a raw material for various functional cosmetics.

금년 종계업계는 지난 4월부터 100원대의 병아리 가격이 7개월간 형성되면서 그 어느때 보다 어려운 시기를 보내야만 했다. 최근에 420원까지 가격이 상승하고는 있지만 장기간의 종계 불황으로 도태 물량이 늘어나면서 나타나는 일시적인 현상으로 어려움이 아직 끝나지 않은 상태이다. 특히 사료가격 인상 등으로 생산비가 상승하면서 농가의 어려움은 더욱 커지고 있다. 본고는 이러한 어려운 현실에도 불구하고 오직 건강한 병아리 생산을 위해 혼신의 힘을 다하고 있는 광천부화장 김진영 씨를 만나 양계인 2세로써 최근의 종계업계 현황과 새해 설계를 들어보았다.

본 연구는 초등학교 실과교과 '동물 기르기 단원'의 병아리 부화수업을 위한 교수-학습자료 개발을 위해서 실시되었다. 본 연구의 진행을 위해서 수정란, 부화기 및 육추기 등의 준비와 동시에 부화수업을 위한 사전 지식이 탐구되었다. 뿐만 아니라 본 수업을 위한 학습지도안이 총 3차시의 분량으로 만들어졌다. 본 수업을 통한 교육적 효과는 아동들로 하여금 직접 경험하고 실습하는 과정에서 배우게 되는 외재적 효과는 물론이거니와 무엇보다도 생명의 소중함을 깨닫게 하는 내재적 가치도 함께 기대할 수 있을 것이다.

육계사육에 있어 생산성 향상을 위해 해야 할 일이 무엇일까? 계사시설, 환기, 병아리 품질, 사료선택등 몇 가지 사항들을 나열해 볼 수 있겠지만 무엇보다 기본이 되고 밑바탕이 되어야만 하는 것이 바로 '사양가'를 꼽을 수있다. 사양가는 병아리 입추부터 출하까지 사육방법에 있어 선택과 결정을 하며 이를 실행에 옮기는 총책임자로서 사양성적으로 결정짓는 가장 중요한 요소인 것이다. 이번호에는 이천지역에서 위치한 명성농장을 방문하여 오랜 기간동안 꾸준히 우수한 성적을 유지하고 있는 사육비결을 들여다 보았다.

산란계업계에서는 부화 직후 숫병아리 초생추를 감별해 내는 것이 일반적이다. 산란계 숫병아리는 계란 생산에 적합하지 않고, 닭고기 생산에도 자원효율이 너무 낮아 결국 조기 처분하게 된다. 최근에 이러한 관행은 동물복지 문제점으로 지적되고 있어 이를 해결하기 위해 부화 기간 중 닭의 성별을 판별하는 기술이 모색되어 왔다. 핸드릭스·제넥틱스사는 2012년 이후 이러한 분야의 개발을 적극적으로 추진해 왔다. 본고는 이 회사의 산란계정보 「Layer Vision」 제22호(2020년 1월 발행)에 소개된 계란 내 감별기술에 대하여 발췌·번역·게재한 것이다.
